What is asthma?

In fact, many people suffer from asthma in life, and it affects everyone regardless of age or gender. However, when it comes to what asthma is, many people may not really understand it. We only know that it will affect our health and life, so let's take a look at what asthma is and what are the factors that cause this disease?

No matter what kind of disease it is, only if we fully understand its symptoms and know the causes of the disease can we really find the right medicine for it. Therefore, in life we ​​should learn more about the symptoms of these diseases and effectively help ourselves treat them.

"Asthma" is a common disease that is characterized by repeated attacks and long-term non-healing. It is a chronic disease. Some asthma patients develop the disease in their adolescence and still suffer frequent attacks in old age. Therefore, there is a saying that “internal medicine cannot cure asthma”. Bronchial asthma is a disease of highly sensitive bronchi caused by certain allergens from the outside world or in the human body (non-allergic factors can also cause it). Due to the bronchi's oversensitivity to irritants (allergens), the bronchi undergo extensive, reversible spasm and stenosis. The clinical manifestations are paroxysmal expiratory dyspnea with wheezing, which lasts for several minutes to several hours and improves on its own after treatment. In severe cases, the symptoms may last for several days to weeks or may occur several times a day, causing great pain to the patients. If asthma persists for a long time, the human body will experience various symptoms of hypoxia, such as myocardial hypoxia and cerebral hypoxia, leading to serious consequences such as angina pectoris, heart failure, and pulmonary encephalopathy. Long-term recurrent attacks are often complicated by chronic bronchitis, emphysema, and cor pulmonale.

Bronchial asthma can occur at any age, but 50% of patients develop the disease in childhood. 20% of patients have a family history. (I) Causes of the disease: (1) Some people with allergic constitutions inhale allergens such as pollen, mites, fungal spores, etc.; eat fish, shrimp, scale insects, milk, eggs; and come into contact with certain drugs such as penicillin. (2) Respiratory tract infections, cold air, irritating gases, mental stress, etc. can cause asthma attacks. (3) Occupational exposure to animal, plant or chemical dusts such as cotton wool, grains, mushroom dust, animal fur, pesticides, plastics, paints, chemical raw materials, etc. (4) Drug-induced asthma attacks, such as aspirin, bacterial vaccines, antivenom, and propranolol. (5) Post-exercise asthma is more common in children and young people. It occurs 2 to 5 minutes after strenuous exercise and can last for tens of minutes to more than an hour. The reason may be related to inhaling cold air, or it may be caused by excessive exhalation of carbon dioxide in the body after exercise and relative lack of oxygen.

The above is a detailed introduction to asthma. After understanding it, we found that there are actually many factors that can cause asthma. Some food allergies in daily life may trigger asthma. Therefore, everyone still needs to pay attention to various preventions, so as to help you stay away from the trouble of asthma.
