What are the symptoms of asthma?

summary

Recently, I read a report that many children have asthma, and the prevalence of asthma is very high. Most of them are caused by allergic constitution and environmental factors, and some are related to polygene inheritance. Genetic factors are usually caused by environmental factors. The main environmental factors are: 1. Inhaled dust mites, pollen fungi, animal fur, 2. Infections such as bacteria, viruses and parasites, 3. Food such as fish, shrimp and crab eggs, 4. Drugs such as aspirin, and climate change. Exercise or pregnancy can cause asthma. Asthma is everywhere. The main symptoms are as follows

What are the symptoms of asthma?

Asthma can also be divided into acute attack period and chronic persistent period and remission period. Acute attack will suddenly occur or aggravate chest tightness, shortness of breath, cough and other symptoms, but also accompanied by dyspnea, low expiratory air flow as its characteristics. The cause of the disease is usually caused by contact with allergen irritants or improper treatment.

Generally, the attack can occur within a few minutes. After a few hours or days, it can be relieved by bronchodilators, and sometimes it can be relieved by itself. When the attack occurs, the chest is over inflated, and the heart rate will increase, abnormal movements of chest and abdomen will appear, and cyanosis will occur. The physical examination can't see the abnormality when it doesn't attack.

The specific cause of asthma is not very clear, usually accompanied by wheezing dyspnea or paroxysmal chest tightness and cough. Those who are more serious will be forced to sit breathing and not to lie down, dry cough or cough up a large amount of white foam sputum, or even cyanosis. The process is very painful.

matters needing attention

Keep away from allergens and minimize unnecessary irritation and contact. Always have bronchodilators around you. Try not to eat hard, cold, fried food. Also try not to eat fish, shrimp, crab, eggs, milk and other allergic food. Usually drink more water to supplement the lost water.
