Asthma is a disease of the airways (bronchi) that affects the smaller lungs, caused by inflammation of the bronchi. In most cases, the public does not know why inflammation occurs, but inflammation can irritate the muscles surrounding the windpipe, causing them to contract, making it difficult for air to enter and flow out of the lungs, leading to wheezing and difficulty breathing. Inflammation also causes mucus to form in the walls of the tubes, causing coughing and further obstructing airflow.<\/p>\n
According to Su Yongbai, a general practitioner in private practice: "When an asthma attack occurs, the patient's bronchi will constrict. Common symptoms are coughing, wheezing, dyspnea, and chest tightness. Symptoms can be mild, but they can also suddenly change to It is very severe, and then returns to normal. Acute asthma can last for several hours or several days. Most patients have constricted airways, which will return to normal naturally or after treatment. However, the symptoms of asthma are generally very typical. Doctors can easily make a clinical diagnosis. If in doubt, they can arrange some simple tests, such as common lung function tests, peak expiratory flow meter, etc. Asthma can occur at any age, but usually starts in childhood, only 5% is Asthma does not appear until adulthood."<\/p>\n
Asthma is a kind of bronchial disease that is difficult to cure. However, Dr. Su said that most patients can improve significantly if they take the medicine as directed. Commonly used asthma medications include bronchodilators, inhaled corticosteroids, and leukotriene modulators. Generally speaking, these drugs are sufficient to reduce airway inflammation and relieve tracheal constriction problems. However, those with asthma problems should follow up regularly and take drugs as needed.<\/p>\n
Dr. Su pointed out that in addition to genetic factors, for adult patients, asthma may also be related to exposure to allergens or substances such as dust mites, smoke, pollen, chemicals and animal hair in the living environment. On the other hand, seasonal changes will affect patients. Whether it is changes in cold or heat, or changes in humidity, there is a chance to trigger asthma. Therefore, November-December and March-April are the peak periods for admission of asthmatic patients. At this time, you should make sufficient preparations to keep warm. You may wish to bring a neckerchief, cap, coat, etc. to go out on the street to reduce the irritation of the trachea and reduce breathing through the mouth. Without the protection of the nose, dry and cold air will directly enter the trachea, which will cause cause asthma.<\/p>\n

2. Pay attention to the weather changes. When you go out in winter or when the cold current hits Hong Kong, you should wear warm clothes.<\/p>\n
3. Avoid eating foods that have caused allergies (such as shrimp, crab, clams) or drugs (such as aspirin, penicillin).<\/p>\n
4. When suffering from respiratory tract infection such as cold and cold, it should be treated as soon as possible and take medicine according to the doctor's instructions.<\/p>\n
