What causes asthma? 1

What causes asthma?

First, allergens. Dust mites, skin scales of cats and dogs, mold, pollen, milk, eggs, silk, feathers, moths, cotton wool, fungi and drugs are all important allergens.

Second, physical and chemical factors. Inhalation of smoke, dust, vegetable oil, gasoline or paint, cold air and other odors can stimulate sensory nerve endings under bronchial mucosa and cause asthma.

Third, infection. Colds and upper respiratory tract infections are the most common causes, especially in winter and spring or when the climate is changeable. Fourth, climate change. It is easy to catch cold in cold season, leading to respiratory tract infection, or sudden weather change and low air pressure.

Fifth, mental emotions. Emotional fluctuations may be the cause. Such as anxiety, sadness, excessive excitement and even laughter can also lead to asthma attacks.

Sixth, excessive fatigue. Aggressive or long-term physical labor and intense competitive exercise can induce asthma.

How to relieve asthma

(1) Patients who smoke should give up smoking first. The incidence of chronic bronchitis is many times higher than that of non-smokers. After quitting smoking, patients' lung function has been greatly improved, and passive smoking should also be avoided.

(2) Strengthen physical exercise and enhance physical resistance. The amount of exercise depends on your physical condition. Walking, boxing, jogging, etc. You can breathe fresh air every morning to promote blood circulation. Winter exercise can improve the adaptability of respiratory mucosa to cold air.

(3) Adjust the room temperature reasonably to prevent colds. In winter, the indoor temperature should not be too high, otherwise the temperature difference with the outdoor is large and it is easy to catch a cold. Summer should not be greedy and cool, and the air conditioning temperature should be moderate, otherwise it is easy to suffer from "cold" and induce bronchitis when going out. Go to the crowd as little as possible during the flu season, sweat a lot, don't take off your clothes suddenly to prevent colds, and pay attention to changing clothes with the seasons. The elderly can get flu shots to reduce the chance of catching the flu.

What causes asthma? 2 The difference between asthma and allergic asthma.

Symptom difference:

1. Symptoms of allergic asthma: This type of asthma will have symptoms of sneezing, runny nose and cough. If not treated in time, it may increase the burden of bronchus, which may lead to asthma. In severe cases, it may be forced to sit or breathe in an upright position. When it is dry, it is easy to have a lot of white sputum and even cyanosis.

2. Symptoms of variant asthma: Its symptoms are dry cough, and it is more serious. The patient coughed for more than 2 months without obvious inducement, mostly at night or in the morning, and the exercise and cold air induced aggravation.

Etiological differences:

1, cause of allergic asthma: allergic asthma is a chronic airway inflammation involving many kinds of cells, especially mast cells, eosinophils and T lymphocytes, which is mostly caused by allergens!

2. The etiology of variant asthma:

(1) endocrine disorders, low activity, malnutrition or overnutrition;

(2) Air quality has a great relationship; (3) Excessive mental stress.

How to treat asthma and allergic asthma?

The main manifestation of asthma is dyspnea and it is very easy to relapse. The treatment of asthma mainly lies in finding allergens, removing allergic factors and relieving tracheal spasm. No matter what type of asthma, you should go to the hospital for examination, actively find out the factors that cause allergies, and then desensitize to recover. In acute attack, anti-inflammatory, antispasmodic, antiasthmatic, antiallergic and symptomatic treatment can be given appropriately.
