Allergic cough is also known as cough variant asthma. Chronic cough (more than 4 weeks) is its only or main clinical manifestation. It often has no obvious symptoms or signs of wheezing and shortness of breath, but it has airway hyperresponsiveness. Mainly manifested as irritating dry cough, usually severe cough, and night cough is its important feature; Cold, cold air, dust, lampblack and deep breathing can easily induce or aggravate cough. There are no obvious signs of infection or cough symptoms that are ineffective after long-term antibiotic treatment.
Many children in allergic cough have begun to appear frequently, especially at this stage, which happens to be the early winter season, and winter is a relatively dry season. Many children don't pay much attention to drinking water, and even play without drinking water almost all day, which will cause respiratory irritation in the process of playing. After that, the situation in allergic cough will be more serious.
Second, find the cause of allergic cough.
Modern medicine thinks that allergic cough has two reasons:
On the one hand, all allergic diseases are induced by contact allergens, which are the basis of allergic reactions. Common allergens include inhaled allergens, such as dust, pollen and animal fur. Biological allergens, such as mold; Food allergens, such as seafood and other foods; Exposure to allergens, such as cosmetics and paints; Physical factors such as sun exposure, cold air and cold water.
On the other hand, individuals are allergic, and allergic constitution is prone to family aggregation. For example, if one parent is allergic, then the child is likely to be allergic. If both parents are allergic, then the child is allergic. There is a high probability that the interaction between allergen and allergic constitution will lead to allergic reaction, and both of them are indispensable.
Third, is allergic cough allergic? How to judge allergic constitution?
Allergy is just a physical definition of allergic people. When exposed to the same substance, healthy people will not be allergic, and allergic people will have allergic reactions. So does the frequent appearance of allergic cough mean that it is allergic? It is indeed possible that you are allergic, because allergic cough itself is closely related to the allergic reaction of the body. allergic cough appears many times in a short time, indicating that the body is in a highly sensitive state. So how to judge allergic constitution? There are mainly the following rules.
1, the probability of allergic diseases is relatively high. For example, you often have allergic cough asthma, allergic virginity, urticaria, eczema and other diseases. If it happens more than four times a year, it is most likely allergic.
2. After outdoor activities, I often feel itchy eyes or nostrils, coughing, sneezing and running nose repeatedly.
If you are a child, you will sweat more than children of the same age and catch a cold more easily. Paroxysmal cough will occur after strenuous activity.
4. Your last generation had a history of allergy.
5. Through allergen testing, I found that you are allergic to many common substances.
Fourth, allergic cough-treatment and life care of allergic constitution
1, general processing
Eliminate the cause. Improve environmental conditions, dustproof, cooling, ventilation, etc. Avoid high temperature drying and inhalation of dust and harmful substances; Strengthen personal protection, such as wearing masks and preventing colds.
2. Western medicine treatment
Antibiotics and antitussive drugs are ineffective in the treatment of allergic cough, so antiasthmatic drugs and antiallergic drugs should be used. Both ketotifen and salbutamol can treat allergic cough. Cough will disappear within 2-5 days after treatment. Some children take medicine for about two weeks before their cough can be relieved.
Allergic cough can be treated step by step or according to the severity of patients' symptoms. At the same time, inhaled hormones can also be used in combination with drugs such as bronchiectasis and anti-inflammatory and desensitizing drugs.
3, immune regulation allergic constitution
Many drugs have a remarkable effect on alleviating the allergic cough problem. However, these drugs are likely to contain antibiotics and hormones, which are harmful to children's health. In addition, these anti-allergic drugs are effective when used, and will recur as soon as they stop, and the symptoms will be more serious. They must be used with care.
In recent years, after many discussions on allergy science, immunologists have found that people with allergic diseases or allergies can improve their immune system if they eat some bacteria that are beneficial to the human body. Among them, six kinds of anti-allergic probiotic strains contained in Xinmin Kang probiotics have a great stimulating effect on intestinal immune system. The results of clinical human experiments confirmed that the allergic respiratory response was obviously slowed down after stimulating the trachea before and during sensitization, and the symptoms such as cough and asthma caused by respiratory allergy were effectively suppressed. Including inhibiting the production of specific IgE antibody, reducing the number of eosinophils infiltrated in respiratory tract, tracheal inflammation and respiratory tract overreaction. In addition, oral administration of Xinmin Kang antiallergic probiotics can induce Th2 overreaction caused by allergen stimulation, so as to correct the immune response and make it become Th 1 normal. Therefore, we come to the conclusion that supplementing Xinminkang anti-allergic probiotics not only helps to adjust the allergic constitution, but also reduces the IgE concentration in the body. Even in allergic season, allergens can't combine with IgE, so allergic reactions don't occur.
4. Life care
Special attention should be paid to the main principles of avoiding cold stimulation, maintaining good physique and avoiding contact with allergens in life; Put on clothes when you get up in the morning to avoid catching cold. Brush your teeth and wash your face with warm water after getting up; After bathing or shampooing, dry your body and hair as soon as possible; Wear a mask when going out or riding a motorcycle or bicycle in cold weather to keep your mouth and nose warm; Don't swim and get wet in the morning; Stop sick children from playing too much and chasing, running and jumping; Please don't be too tired or stay up late, try to ensure enough sleep and maintain strong physical strength; Avoid allergies caused by dust mites.
