Asthma

 

Asthma is a chronic disease, swallowing, or narrowing of air passageways, creating extra mucous. This condition makes breathing difficulties, whistling sounds, wheezing, shortness of breath, and coughing. 

Asthmatic patients’ airways are always inflamed and sore. When something triggers asthmatic patients, the muscles around airways become tight, creating more difficult breathing, even problem in air exchange, and causes chest tightness.

Timings of asthmatic attacks depend on patient physical activity. Sometimes asthma is a minor nuisance for some people, while mostly it interferes in every action and leads to life-threatening asthmatic attacks. 

Asthma can't be treated but can control, consulting with your doctor.

Symptoms:

Asthmatic signs and symptoms include

Pain and chest tightness

Trouble in sleeping due to shortness of breath, coughing and wheezing.

Whistling sounds during exhale (especially in children).

Wheezing and coughing attacks worsen due to viral infections, exceedingly cold, and flu.

Shortness of breath

Types of Asthma

Allergic Asthma 

Adult-Onset Asthma

Asthma-COPD Overlap

Nonallergic Asthma

Occupational Asthma

Exercise-Induced Bronchoconstriction (EIB).

Exercise-Induced Bronchoconstriction (EIB).

As we all know, Staying active will keep you healthier and profitable for muscle strength. Still, your consultant physician makes you a proper schedule for exercise for Asthmatic patients, according to your physical report. Proper management is required to keep symptoms under control; otherwise, the conditions become worse and fatal. A chronic asthmatic patient can have an attack during exercise.

Adult-onset Asthma:

This type of asthmatic condition occurs in people older than 20 years. Usually occur in women during pregnancy or after menopause. Lung function tests can diagnose it through a spirometer device. Calculate the rate of inhaled or exhaled air through the lungs.

Allergic Asthma 

It can trigger by airborne particles, pollens, dust, slits, pet dander, mould spores, and skin particles.

Occupational Asthma:

The most common type occurred by workplace irritants including, chemical, gases, and fumes.

Asthma-COPD overlap:

 It terms as ACOPD, not a separate disease but an overlap disorder caused by some factors. Mostly asthma occurred in childhood while COPD at age 45 or above. The causing reason for asthma is unknown, but COPD is due to smoking.

Nonallergic Asthma:

Some nonallergic factors are activated by stress, smoke, viral respiratory infection, anxiety, cold air, and worse throat.

Causes:

It's complicated to say why people get asthma, a combination of genetic and environmental factors. Some allergic factors make your airways swallowed and narrow, causing difficulty in breathing. Untreatable conditions make it worsen and cause a severe stage of asthma that can be fatal. 

Diagnosis:

 Doctors can diagnose them by taking some medical history through your symptoms and performing physical lung tests using a spirometer device. Chest X-rays also help to distinguish between asthma and pneumonia. 

Asthmatic Triggers:

Many irritants activate asthma, including many allergy-causing agents, but it depends and varies from person to person.  

Respiratory infections

Physical activities

Air pollutants such as smog and pollen

Some kind of medications including, Aspirin, Beta-blockers, nonsteroidal anti-inflammatory drugs, naproxen sodium and ibuprofen.

(GRD)Gastroesophageal reflux disease, a stomach disorder in which the stomach acid back up in your throat.

Risk Factors:

Various factors involve increasing your chances of getting asthma;

Genetic factors, you get through your siblings or close relative genetically.

Atopic dermatitis (red itching fever) or hay fever (coagulation, runny nose, eye itching problem).

Obesity and being overweight.

Smoking

Exposure to occupational activators like farming, hairdressing and smog.

Complications in Asthma:

Continuously narrowing of bronchial tubes affects your breathing rate.

Signs and symptoms with asthmatic server attacks can disturb your working ability.

Asthmatic attacks and whistling sound cause sleeplessness, which lead to anxiety and depression.

There are many severe side effects of long-term medications used for controlling asthma.

But proper treatment and preventions can overcome long term and short-term complications.

Preventions:

you and your physicians can control it by proper management. Design a step by step plan of life, change your lifestyle according to it. It will surely help in preventing asthmatic attacks.

Follow your Asthmatic Management Plan: Make a plan with the complete guidance of your doctor and medical care team; that plan is about taking medicines, vaccines, exercise, diet plans to prevent attacks. Strictly follow it; being a persistent disease, you need regular treatment and diagnosis. 

Get vaccinated for influenza and pneumonia. Take vaccinations against viral infections and try not to get common cold and flu because it triggers asthma. 

AvoidTriggers. Many sorts of asthmatic activators and allergy, causing irritants to avoid the stop in inhaling them through a face mask— ranging from pollen and mould spores and cold air and pollution — can trigger asthma attacks. Try to Find out what worsens your asthma, create your asthmatic attacks, and avoid those triggers. 

Monitor your breathing Rate. Record your breathing rate with home peak instruments, and whenever you feel it's abnormal and some shortness of breath, instantly take your medicines; it will overcome the severeness of attack.

Take proper medication as prescribed. Do not take or change your medicines without consulting with your doctor. Even your asthma seems good to take your medication correctly, keep your medicine all time with you.

Use a quick-relief inhaler. Use inhalers such as albuterol in shortness of breath. If your asthma isn't under control, then seek medical consulting's about adjusting your treatment.

Treatment

Bronchial thermoplasty:

Therapeutic radiofrequency energy through electrodes to air passageways reduces muscle tightness, only for severe conditions not widely available.

Bronchodilators:

It can take as a nebulizer, help in relaxing muscle stuffiness within a minute, and open the airway.

Anti-Inflammation: Use or inhales corticosteroids or other anti-inflammatory drugs that help to breathe correctly. 

Anticholinergics: They help to prevent muscles from tightening around airways. 

There is no cure for asthma but can control by managing your lifestyle and proper treatment. Untreated asthmatic conditions can lead to permeant loss of lungs

Asthma Overview Content

 

 Asthma is a narrowing of the airways, causing difficulty breathing. Understand the causes, symptoms, diagnosis and treatment of asthma. What is asthma? Asthma affects the lungs of children. The most common symptoms of asthma are asthma, coughing, and breathing problems. Other health problems can also cause these symptoms. Therefore, it is difficult for doctors to diagnose asthma at first, especially in infants and children. Asthma affects your child's lungs for life. Sometimes the child feels better. Sometimes it feels severe. When the child’s asthma is more affected If your child’s asthma is more affected, the airway will become narrower. At this time, it is difficult for the child's lungs to inhale and exhale air. Asthma airway constriction During an asthma attack, the muscles around the airways become tight, The airway narrows, making breathing difficult. Children with asthma have three factors that narrow the airways: The airway lining thickens and expands. This is called inflammation. The muscles around the airway tighten. This is called bronchospasm or bronchoconstriction. The airway produces a lot of transparent mucus. This mucus is thicker than normal and can block the airway. Help children feel more comfortable There are several ways you can help your child feel more comfortable: Read this page to learn more about childhood asthma, read other books on asthma, and consult a doctor. Make sure that your child takes the medicine exactly as prescribed by the doctor. Understand the causes of childhood asthma and try to stay away. Triggers can aggravate your child’s asthma. Incentives aggravate your child’s asthma Triggers can aggravate your child’s asthma. Every child with asthma suffers from different triggers. Cooperate with your child’s doctor to find out the triggers that trouble your child and understand how your child can avoid these triggers. The following are some common triggers: Infectious diseases, such as colds and flu Cigarette or tobacco smoke Woodsmoke and lampblack Things that cause allergic reactions pet Air pollution Humid climate Cold weather Drugs, such as ASA (aspirin) or ibuprofen Strong smell or spray movement Asthma medication Asthma medicine can keep your child’s lungs healthy and prevent your child’s asthma from getting worse. These drugs cannot treat asthma, but they help keep your child’s lungs healthy. Many asthma medicines used by children are inhaled. These medicines are called inhaled medicines. Corticosteroids are one of the best-inhaled asthma drugs. Studies have shown that inhaled medicines for childhood asthma are very safe. Your child can use it for several years without affecting growth. After inhaling the medicine, children should rinse their mouth or drink a sip of water or juice. This helps prevent sores in the mouth. The main inhaled drugs used for childhood asthma are control drugs and relievers. Asthma control drugs are drugs that prevent the lining of the airway from swelling. With daily use of control drugs, your child’s swelling and mucus volume will decrease. Inhaled control drugs include beclomethasone (Qvar), budesonide (Pulmicort), budesonide plus formoterol (Symbicort), ciclesonide (Alvesco), fluticasone (Flovent) and fluticasone plus salmeterol (Advair) ). Singulair is a tablet-type control drug. Even if it looks good, your child should take control medications every day. Make sure your child continues to use the control medicine until the doctor allows it to stop. Asthma relief medicine Relief medications can help treat asthma symptoms such as cough or asthma. Relief drugs can relax the muscles around the airways. The airway opens after the muscles relax. At this point, the child can breathe more easily. Relief medications include salbutamol (Airomir or Ventolin) and terbutaline (Bolicani). If your child has asthma, relievers should be used. If the doctor thinks that the child has improved, stop using the daily relief medicine. The doctor will tell the child to use relief medication before exercising. Early warning signs of worsening asthma in children Asthma symptoms appear slowly over time, usually hours or days. The small changes in your child's body when symptoms of asthma appear are called early warning signs. The early warning signs are different for each child. You will find these signs are not easy to detect. Here are some common early warning signs. Signs you can see or hear Persistent cough Coughing to vomiting Night cough asthma Have difficulty breathing Fatigue soon after starting a game or exercising Breathing faster than usual Impatient temper, unstable temperament Signs of a cold sneeze What the child tells you "I'm tired." "My chest hurts." "Difficulty breathing." "There is noise when breathing (asthma)." What to do when your child shows early warning signs If you see any early warning signs, follow the action plan that you and your doctor have developed together. If you have not made an action plan, consult your doctor to make it. Danger signs that your child's asthma gets worse If your child shows any of the following signs of danger, be sure to follow the action plan that you and your doctor have developed together. Unable to stop coughing and vomiting Difficulty speaking Feeling tired and unable to wake up Blue lips or skin Inhale (inhale) the skin on the neck or chest when breathing Follow the action plan to let your child use relief medication. Take your child to the nearest emergency department or call an ambulance. Asthma and exercise Although suffering from asthma, the child is still very active and likes to exercise. All children should play and exercise. Your child needs to play with other children to maintain healthy growth. Sports will aggravate some children's asthma We know that exercise can make some children's asthma worse. Your child will show some warning signs of asthma during and after exercise. During exercise, children can perform some operations to suppress asthma: If you use control medications regularly, the signs of asthma will decrease during exercise. Make sure your child does simple, gentle exercises when starting and ending exercise. That is to warm up and ease exercise. The doctor will tell the child to use relief medication before exercising. Keep in mind that relievers can help treat asthma symptoms such as cough or asthma. If your child uses these drugs 15 or 20 minutes before exercise, it will reduce the warning signs of asthma. If asthma gets worse during exercise, the child should do some short-term exercise and rest during exercise. If your child starts asthma while exercising, he should stop the activity. Then, your child will follow the action plan that you and the doctor have made. Important matters With asthma or, even if your child looks better, his airway will swell for 6 to 8 weeks, or even longer. The child should continue to use the control medicine. You should follow the action plan that you and your doctor have made. This is a written action plan that records the daily activities of how to control asthma. The plan also records what to do when your child’s asthma gets worse. If you work hard to keep your child away from things that aggravate asthma (asthma triggers), you can help your child prevent other symptoms of asthma. If your child is over 6 years old, you can consult a doctor about the "inflation" test for asthma, which is a lung function test. This test is used to diagnose and monitor asthma. Emergency situations If the following conditions exist seek medical attention immediately: Relief medication is ineffective or lasts 4 hours The child's symptoms do not get better after 2 to 3 days Child's symptoms get worse If the following situations occur, go to the nearest emergency department immediately: Your child is unable to eat, sleep or talk due to the onset of symptoms Your child has shortness of breath or aspiration in the throat or under the ribs Extra doses of relievers are still ineffective Point The most common symptoms of asthma are asthma, coughing, and breathing problems. When a child's asthma attacks, his airways will narrow, which makes it difficult to inhale and exhale from the lungs. Make sure that your child takes the medicine exactly as prescribed by the doctor. Find the cause of childhood asthma and try to stay away. If you notice any early warning signs of worsening asthma in your child, follow the action plan that you and your doctor have made. Dangerous signs of asthma include difficulty speaking, sleeping abnormally or waking up, blue lips or skin, and inhalation of the neck or chest skin while breathing. If you see these signs, give your child a relief medicine. Take your child to the nearest emergency department or call an ambulance.

Health care for patients with asthma

 

1. What is asthma? Asthma is a chronic bronchial disease. The patient's bronchial tubes become swollen and narrowed due to allergic inflammation, making breathing difficult. Asthma is a global problem, with 300 million asthmatics worldwide. The incidence and severity of asthma are increasing, and 180,000 patients die from asthma every year. The medical use and cost are very high. The general rule: cities are higher than rural areas; more children than adults. 2. What are the clinical manifestations of asthma? Symptoms such as recurrent wheezing, shortness of breath, chest tightness or coughing often develop and aggravate at night and (or) in the morning. Most patients can relieve themselves or be relieved by treatment. At night, yang is latent in the human body (hormone levels decrease), inflammatory cell infiltration in the airway increases and inflammatory substances are produced, which makes asthma symptoms more obvious. Also Besides, exposure to allergic factors or poor asthma control can make asthma symptoms worse at night (taking long-acting control drugs every day to control asthma inflammation can avoid night attacks) 3. What are the causes of asthma? Genetic factors Environmental factors Indoor allergens Outdoor allergens Smoking 2 Air pollution Factors that worsen asthma Allergens Air pollution Respiratory infections Exercise and hyperventilation Climate change Sulfur dioxide Food, additives, medicines

4. What is the relationship between climate change and asthma attacks? Changes in temperature, humidity, and air pressure may all be factors that induce asthma. According to the survey, the incidence of asthma is the lowest in the hottest seasons, and higher in autumn and winter, but most patients who relieve in summer can also cause asthma attacks due to inhalation of certain irritants, smells or ingestion of certain substances. Asthma can occur in the same season, but it can also occur repeatedly in different seasons. Acute airway stenosis and increased airway resistance that occurs after strenuous exercise. It may cause exercise-induced asthma in patients, especially teenagers (at this time, please consult a doctor to control asthma). 5. Asthma patients need to pay attention to their disease. (1) Asthma patients’ cognition of their own condition is still far from their actual symptoms, and they tend to underestimate their actual symptoms and pay attention to them after a severe attack. This leads to increasingly serious symptoms, even due to ineffective treatment. Face danger to life. 3 Surveys have shown that more than 80% of patients fail to effectively control their disease, which means that they will face the risk of severe asthma attacks and long-term lung damage. (2)  asthma is harmful. A sudden attack of asthma can cause pneumothorax, respiratory failure, and even life-threatening; growth and development disorders, obstructive pulmonary disease and chronic pulmonary heart disease, missed work and miss study affect children’s mental development, asthma is poorly controlled, and the accumulated inflammation can cause permanent damage to the respiratory tract, seriously affecting the patient Lung function and future life. Therefore, the control of asthma inflammation is the most important, which requires daily use of asthma control drugs to curb the deterioration of asthma. 6. What should I do if I have asthma? 1. Western medicine inhalation therapy In 1994, the World Health Organization formulated a global strategy for asthma management and prevention, namely the Global Asthma Prevention and Treatment Initiative-GINA. The global asthma academic community unanimously recommends inhalation therapy. Every patient should carry a bronchodilator (Trone) with them in case of emergency. It is necessary to persist in inhaling corticosteroids (Seretide, fix done, and be done) every day for anti-inflammatory. Inhaled corticosteroids can solve the fundamental problem of asthma. Asthma is a chronic disease of the airway. Like other chronic diseases, such as diabetes and hypertension, asthma also requires long-term medication control. Why advocate inhalation therapy? Compared with oral administration, inhalation therapy has the following advantages. The medicine can reach the lungs. 4. Small dosage, fast action, high safety, and good curative effect. 2. Chinese medicine treatment Chinese medicine believes that the spleen is the source of sputum, the lung is the organ for sputum storage, and the kidney is the main source One of the functions is to receive qi. Therefore, the lung, spleen, and kidney function are imbalanced, and asthma can occur. In the treatment, the lung, spleen, and kidney functions are also regulated. When there is no seizure, strengthening the body is the first, that is, to supplement the law; when the seizure is the main attack, that is, to reduce the law. Specifically, you need to ask a Chinese physician for syndrome differentiation and treatment. 7. What is the relationship between allergic rhinitis and asthma? Allergic rhinitis is manifested as itchy nose and eyes, sneezing, nasal congestion, and watery nasal discharge. Statistics show that among patients with bronchial asthma, about 56%-74% have allergic rhinitis, and the incidence of bronchial asthma in patients with allergic rhinitis is greater than 60%. It can be seen that the relationship between allergic rhinitis and bronchial asthma is relatively close, and allergic rhinitis should be actively prevented and treated to reduce the incidence of bronchial asthma. Eight|Can asthma attacks be prevented? The precautionary principles are 1. Look for predisposing factors: minimize the chance of triggering an asthma attack. 2. Enhance immunity and physique 5 (1) Medical physical exercise (before various exercises, a small number of bronchodilator drugs can be used to prevent asthma attacks) (2) Lifestyle (keep a happy mood) (3) Drug prevention ( Use regularly) Specific prevention methods: 1. Avoid allergens. Common allergens include wind pollen (medium tree, castor, wormwood, etc.), mould spores, house dust, certain productive dust (such as cotton dust, silk moth dust, yam powder, certain detergents and certain Stimulating gases and drugs from chemical plants), etc. The room should be ventilated on time, the light should be sufficient, and the temperature should be appropriate. When cleaning the bedding and cleaning and spraying alcohol and insecticides, ensure that the patient leaves the scene, quit smoking, etc. to prevent air pollution 2. Pay attention to summer treatment. From the small summer to the beginning of autumn, it is called "Fuxia" or "Dogtian", which is the time when the temperature is the highest throughout the year and the sun is the strongest. "Spring and summer nourish yang", treatment at this time can enrich the patient's yang energy and enhance disease resistance. 3. Pleasant emotions. Many clinical data indicate that 30% of -70% of asthma is induced by emotional factors. Emotional triggers mainly include excessive tension and anxiety, especially worry, grievance and anger. Although these are not the primary causes of asthma, they can affect the number of attacks and the condition. Therefore, patients with asthma should be happy, open-minded, and avoid emotional stimulation to avoid recurrence. 4. Pay attention to diet and recuperation. Avoid eating foods that can induce asthma, such as crabs, shrimp, and milk. Eating should not be too sweet (such as chocolate), too greasy (such as animal fat), not too aggressive (such as cold ice cream, spicy, wine, strong tea, etc.). Vegetables such as radish, loofah, and canavalinus can not only supplement a variety of vitamins and inorganic salts, but also have the effects of expelling wind, lowering qi, and reducing phlegm, which is beneficial to prevent asthma attacks. To prevent vegetable food from getting colder, add a proper amount of ginger when cooking. Eating a certain amount of pears, citrus, loquat, walnut kernels, bananas, sesame seeds, honey, etc. can help smooth stools, reduce abdominal pressure, and prevent asthma attacks. 6 It is necessary to pay attention to prohibit smoking and alcohol, quit smoking and more tea. Because smoking can cause increased secretions in the respiratory tract, reflex bronchospasm, and difficulty in expectoration, it is conducive to the growth and reproduction of viruses and bacteria and makes chronic bronchitis worse. Tea contains theophylline, which can excite the sympathetic nerves, dilate the bronchi and reduce the symptoms of cough and asthma.

5. Avoid fatigue. Because of overwork, it will consume righteous qi, damage the internal organs, cause low resistance, and become a trigger for asthma attacks. 6. Insist on proper exercise. You can choose medical exercises, Tai Chi, Wu Qin Xi and other items according to your physical fitness to improve the body's disease resistance. The amount of activity should be no obvious shortness of breath, accelerated heartbeat, and excessive fatigue. Physical exercise should pay attention to gradual and orderly progress, and do what you can Prevent overwork, such as walking, Tai Chi, etc. Studies have shown that exercises of less than 5 minutes are less likely to cause asthma attacks, and 5-10 minutes of vigorous exercise can cause asthma attacks. 7. Establish a good doctor-patient relationship. As a chronic disease, long-term treatment is imperative for asthma. Strengthening the communication and exchanges between doctors and patients can make the disease of asthma patients better controlled. Only with good treatment and complete control can patients be more confident in overcoming asthma

Asthmatic Bronchitis

 Asthmatic bronchitis is a chronic airway inflammation involving a variety of cells, especially mast cells, eosinophils, and T lymphocytes. In susceptible persons, this inflammation can cause recurrent symptoms such as wheezing, shortness of breath, chest tightness, or coughing, which usually occurs at night or in the early morning. Such symptoms are often accompanied by extensive and variable restriction of expiratory flow rate, but can be partially relieved naturally or after treatment; this symptom is also accompanied by increased airway responsiveness to various stimulating factors.

Asthmatic bronchitis is not the same as asthma. We know that The trachea, bronchi, and bronchiole are relatively narrow, and the elastic fibres around it are not well developed. Once infected by viruses or bacteria, the mucous membranes will become congested and swollen, leading to spasm of the bronchi and bronchiole. Asthmatic bronchitis is asthma that appears based on infection, and its clinical features are 1. It is common in puffy children under 3 years old. 2. Often have a history of eczema or other allergies. 3. Most of them have expiratory dyspnea, shortness of breath, and flapping of the nose 2-3 days after the upper respiratory tract infection. In severe cases, there may be triangulation, that is, the suprasternal fossa, intercostal space, and supraclavicular depression. 4. Auscultation of both lungs is dominated by wheezing, prolonged exhalation, often accompanied by moderate wet rales. 5. There is a tendency to recur. As most children grow older and the body's resistance increases, the number of attacks will gradually decrease until they are cured. The connection between asthmatic bronchitis and asthma Although asthmatic bronchitis is not the same as asthma, there is a certain connection between the two. Some asthmatic bronchitis can easily develop into asthma after a few years: 1. Patients with asthmatic bronchitis often have a clear family history or patients with allergic reactions and allergic diseases in the family; 2. Asthma symptoms occur repeatedly, and often still cannot be relieved with age. 3. Non-infectious factors such as allergies often cause attacks; 4. A small dose of epinephrine was injected subcutaneously at the time of the attack, and the effect was immediate. Therefore, for asthmatic bronchitis with the above four points, follow-up should be strengthened, and under the guidance of a doctor, preventive measures should be action taken to prevent a recurrence Disease complications edit Pneumonia, emphysema, bullae, pulmonary heart disease, bronchiectasis, etc. Pathological editing of aetiology The aetiology of asthma is not very clear. 

Many survey data show that the prevalence rate of relatives of asthma patients is higher than the group prevalence, and the closer the kinship, the higher the prevalence; the more severe the patient’s condition, the higher the prevalence of their relatives. The genes related to asthma have not yet been fully clarified, but studies have shown that there are multiple genes related to allergic diseases. These genes play an important role in the pathogenesis of asthma. Precipitating factors Environmental factors also play an important role in the onset of asthma. There are many related predisposing factors, including inhaled antigens (such as dust mites, pollen, fungi, animal dander, etc.) and various non-specific inhalants (such as sulfur dioxide, paint, ammonia, etc.); infections (such as viruses, Respiratory system infections caused by bacteria, mycoplasma or chlamydia); food antigens (such as fish, shrimps and crabs, eggs, milk, etc.); drugs (such as propranolol, aspirin, etc.); climate change, exercise, pregnancy, etc. All may be predisposing factors for asthma. 1. Respiratory tract infection Asthma has an important relationship with respiratory tract infections. Upper respiratory tract infection is a relatively common predisposing factor. Most asthma patients experience increased wheezing after respiratory tract infection, which is more pronounced in children. Investigations have shown that the main cause of asthma exacerbation is viral respiratory infections. Respiratory tract infections have the potential to increase the anti-inflammatory effects of the airways, and this factor is very similar to the pathogenesis of asthma. 2. Non-specific factors Dust, gasoline, smoke, pain, and other irritating odours and cold air can stimulate the sensory nerve endings of the bronchial mucosa, reflexively cause vagus nerve excitement and cough and cause bronchial smooth muscle spasm based on airway hyperresponsiveness. 3. Overwork Both intense exercise and long-term physical work can induce asthma. 4. Mental reasons Severe changes or fluctuations in mood can be predisposing factors for asthma attacks. Sadness, worry, overexcitement, and even laughter can also cause asthma attacks. 5. Occupational reasons, For example, pharmaceutical factories and chemical companies are allergic to certain drugs and raw materials, and medical staff is allergic to certain drugs. 6. Climate factors: temperature, air pressure, humidity, etc. 7. Exercise factors Because exercise-induced asthma is also called exercise-induced asthma, it refers to acute and temporary obstruction of the airway after a certain amount of exercise. Clinically, the main manifestations of an acute attack of asthma are different in severity, and it can be relieved by itself. 8. Foggy and dusty environment. Smoking, special odours (odours, fireworks, mosquito coils, car exhaust, campfire smoke, etc.), cooking fumes, etc. can all be asthma triggers. Dichlorvos and insecticides can also aggravate the patient's condition in the summer in my country. 9. Air-conditioned rooms with the obvious temperature difference between entering and leaving I know the cause and pathology of asthmatic bronchitis. The symptoms of asthmatic bronchitis and asthma-related symptoms include coughing, wheezing, dyspnea, chest tightness, and expectoration. The typical manifestation is exhalation dyspnea with episodes of wheezing. In severe cases, they may be forced to sit or breathe, dry cough or spit a lot of white foamy sputum, or even cyanosis. Asthma symptoms can occur within a few minutes, after a few hours to a few days, with bronchodilators or self-relief. Most patients with early or mild symptoms have episodic cough and chest tightness as their main manifestations. These manifestations lack characteristic

Differential diagnosis (1) Bronchopneumonia Severe bronchitis and bronchial pneumonia are sometimes difficult to distinguish in the early stage, but in general, bronchial pneumonia has shortness of breath and respiratory obstruction and fixed small moist rales can be heard in both lungs, especially at the bottom of the lungs; beside the spine and under the armpits, it is obvious. (2) Bronchial asthma The disease is more common in older children with a history of recurring asthma. Asthma attacks can be unrelated to infections or can be induced by infections. Generally, there is no fever, and it often occurs suddenly in the morning or at night. The application of bronchodilators can quickly relieve it. (3) bronchiolitis Mainly caused by a respiratory syncytial virus infection, more common in infants less than 6 months old. The onset of illness is often sudden. At the beginning of the illness, the respiratory symptoms are far more serious than those of poisoning. It is manifested as episodic wheezing, expiratory dyspnea, obvious tri-concave sign, and cyanosis, generally not high body temperature, obvious wheezing in both lungs, lungs There may be fine wet rales at the bottom. Also Besides, recurrent bronchial inflammation should be distinguished from bronchial foreign bodies, congenital upper respiratory tract malformations, right middle lobe syndrome, and other diseases. Related information edit Asthmatic bronchitis should also be distinguished from cardiac asthma, the former is mainly dyspnea It is more common in young people with normal blood pressure, while the latter has difficulty breathing and exhaling. There are more middle-aged and elderly people with symptoms such as high blood pressure and arrhythmia. It is difficult to have a long-term effective treatment plan after suffering from asthmatic bronchitis. When the onset occurs, you should stay in bed, take a semi-sitting position, keep the environment quiet and sanitary, and avoid allergic stimulation. In general, anti-asthmatic drugs can be used in treatment. For collapsed patients, it is necessary to rehydration in time and eats salt and sugar water appropriately to prevent dehydration
