Bronchial asthma is what we often call asthma, when asthma attacks, you can see that the patient has difficulty breathing, very uncomfortable, asthma is easy to recur, and serious may lead to death, pay more attention in life to prevent this disease, so how to prevent bronchial asthma?

1. How to prevent it

(1) Quit smoking and limit alcohol

Cigarettes can cause many diseases, and the chemicals in cigarettes and the smoke emitted when smoking have a direct effect on asthma sufferers, as they can irritate the respiratory tract, so patients should quit smoking. In addition, patients should avoid passive smoking as much as possible. Alcohol should also be consumed sparingly.

(2) Avoid contact with allergens

People with asthma should be aware of which substances may irritate their respiratory tract and try to avoid contact with them, for example, patients who are sensitive to animal hair should not keep pets at home, and other allergens that are prone to cause illness such as blankets, etc., should also avoid contact with them, or wash them with hot water every week.

(3) Prevention of respiratory tract infections

When the weather is cold, inhaling cold and dry air is not good for people with asthma, so try to avoid going out during an asthma attack. If you must go out, drink some warm water and wear extra clothes before going out. It's a good idea to wear clothing that protects you from wind and rain to help keep you warm. If necessary, wear a scarf or mask to protect your mouth and nose to avoid direct exposure of your respiratory tract to cold air and try to inhale warm air. People who are not allergic to the influenza vaccine can get the flu vaccine.

(4) Keep indoor air circulation and clean

Asthma patients should pay special attention to indoor cleanliness and air ventilation, as dust mites and bacteria in the air are the main allergens causing asthma attacks, so they should be cleaned frequently to reduce dust in the air.

(5) Moderate exercise

Some people stop all exercise because exercise may trigger asthma, which is actually a wrong approach, because exercise can effectively enhance the heart and lungs, which can greatly help control the disease.Asthma patients can exercise as usual as long as they consult their doctor before choosing exercise, and swimming is a very suitable exercise for asthma patients, because there is enough water, so most of them will not cause illness.

2. Asthma dietary contraindications

(1) Seafood

Asthma is easily induced by allergic factors, and seafood allergy is also a common allergic disease, so asthma patients with a history of seafood allergy or allergies to seafood should usually eat less or try not to eat seafood products such as fish, shrimp, crabs, etc.

(2) Spicy

Because spicy food can irritate the airways and worsen symptoms in people with asthma, people with spicy foods such as onions, garlic, ginger, pepper, and star anise should stay away.

(3) Cold food

In the summer, many people eat cold and refreshing foods such as ice cream and smoothies, but asthma sufferers should stay away from these cold foods even in summer. This is because these cold foods can irritate the patient and cause certain allergic reactions.

3. Asthma treatment

Asthma treatment medications can be divided into two main categories, namely reliever medications and control medications. Palliative medications used in acute asthma exacerbations provide rapid relief of symptoms and should be carried with the patient at all times and used when necessary.At the same time, relieving drugs can also be used to prevent exercise-induced asthma, and can be used 10~15 minutes before exercise if clearly ordered by a doctor. Control drugs are mainly used for long-term asthma control and therefore need to be used for a long time. Such as inhaled corticosteroids, long-acting beta-2 agonists. Placing both drugs in the same inhalation device reduces inflammation in the airways and relaxes the airways for good asthma control. When inhaled corticosteroids are swallowed into the body, they can be excreted quickly without side effects. Adverse effects of inhaled hormones are mild, mainly local effects, such as hoarseness and oropharyngeal candida infection, which can be avoided by using a spacer and rinsing the mouth after medication.

Although there is no single treatment or drug that can cure asthma, a large clinical trial has shown that continuous inhalation therapy with fluticasone propionate and salmeterol can achieve good control in 80% of patients with bronchial asthma.Severe refractory asthma is very difficult to treat and control, and it is difficult to effectively control it with drugs, so it is necessary to carry out in-depth individualized treatment of severe asthma, and remarkable progress has been made in the surgical treatment of asthma in recent years.

If you have asthma-related symptoms, you must go to a regular hospital in time, carry out standardized treatment under the guidance of a doctor, find a treatment that suits you, and insist on rational medication. It is understood that through standardized treatment and adherence to rational drug use, the complete control rate of asthma can reach 45.3%.
