Phlegm will appear when the weather is cold.

Allergic cough, also known as cough variant asthma, is an allergic disease. Allergic cough's clinical manifestations are: chronic cough without cause for more than two months, paroxysmal irritating dry cough, or a small amount of white foam-like sputum; When inhaled, it can aggravate the irritating smell; Many antibiotics were ineffective, and there was no obvious abnormality in chest X-ray or CT examination. According to experts, through clinical examination, allergic cough can be diagnosed if eosinophils increase and serum IgE is above 200. Allergic cough is more common in children, with a long course of disease and easy recurrence of symptoms, which often gives people the impression that it is difficult to cure.

Etiology of allergic cough.

Two factors caused by allergic cough: one is allergen; Second, allergic constitution; Only both, allergens are only inducing factors, but in the final analysis, the cause is human allergic constitution.

1, allergic constitution refers to the innate defect of immune function in the body, and the immune response in the human body will reduce the number of TH 1 cells. After foreign related antigen substances (pollen, mites, fungi, etc.). ) Entering such a human body, it will continuously produce a variety of cytokines such as IgE and eosinophil production, promote the immune response to form a humoral immune response to TH2 pathway, and produce a series of harmful reactions.

At the same time, allergies are hereditary. When both parents are allergic, their children are 80% likely to be allergic; Simple mother allergies, children have a 50% chance of allergies; A simple father is allergic, and his children are 40% likely to be allergic.

2. Allergens. Including diet, inhalants, climate, exposure to allergens and so on. Among them, seafood, spicy food, wine, inhaled pollen, dust mites, cold weather, exposure to chemicals, soap and detergents are the most common inducements in allergic cough. For such complicated reasons, allergic cough has repeated attacks due to the interweaving of various pathogenic factors and inducing factors.

Allergic cough's repeated misunderstanding: Anti-allergic drugs can be used immediately when you are sick. Most of the immediate antiallergic drugs are antihistamines and hormones, which have no therapeutic effect on the progress of allergic diseases. Repeated use or ineffective or serious adverse reactions may easily lead to obesity, decreased resistance and other problems. Therefore, we should change our ideas and pay attention to the treatment in remission. Therefore, the experts put allergic cough mainly pays special attention to the four methods:

1, avoid allergens

Once exposed to allergens, it often leads to allergic cough's perennial attacks. Therefore, for patients in allergic cough, the way to avoid recurrent allergic cough is to avoid allergens.

Common allergens are as follows: 1, contact allergens: such as cold air, hot air, ultraviolet rays, radiation, cosmetics, shampoo, detergent, hair dye, etc. 2. Inhalable allergens: such as pollen, mites, catkins, dust, animal dander, paint, oil fume, etc. 3. Edible allergens: such as milk, beef and mutton, eggs, fish and shrimp, seafood, etc.

2. Improve allergic constitution

Antibiotics are widely used in clinical treatment in allergic cough. Antibiotics are mainly composed of antibiotics, most of which are broad-spectrum, killing a large number of probiotics in the human body while killing pathogenic bacteria. Therefore, the key to treat allergic cough is to reverse allergic constitution. Modern medical research on microecology has found a new strain group of antiallergic lactic acid bacteria. One or more strain compositions represented by Xinmin Kang anti-allergic probiotics have the ability to improve anti-allergy, which is unknown in the prior art, and the method of regulating TH2 immune response overreacted due to allergy by enhancing TH 1 immune response. It is mainly to seek alternative anti-allergic therapy other than drugs, and to improve the ecological balance of intestinal microorganisms, the largest immune organ of human body, by using active and non-pathogenic microorganisms, so as to promote the secretion of interferon and regulate the activity balance of immune cells. Xinminkang anti-allergic probiotics have the international patent certification of reducing serum IgE allergic antibody. After continuous supplementation for more than 8 weeks, the concentration of IgE in the body decreased, so that allergens gradually could not combine with IgE antibodies in the body, and thus allergic biochemical reactions no longer occurred. Therefore, Xinmin Kang probiotics can regulate allergic constitution, while drugs can only relieve symptoms, but not regulate allergic constitution.

3. Develop good living habits

The occurrence of allergic cough is closely related to the working conditions and lifestyle of patients, as well as air pollution and other factors. Therefore, in normal times, we should adjust our lifestyle reasonably according to our own situation. At ordinary times, we should maintain a healthy diet, quit smoking and drinking, at the same time, we should maintain the law of life, pay attention to the combination of work and rest, and don't be too tired.

4, prevent colds, improve the body's ability to adjust.

Allergic cough is mostly caused by colds. Therefore, you should pay attention to keep warm at ordinary times, and you can raise your head and shoulders slightly with a pillow when you sleep. The temperature in the bedroom should be moderate, not too cold. Pay attention to keep warm when sleeping, especially your feet. During the cold epidemic, wear a mask when going out, avoid public meetings, go to public places as little as possible, and reduce the possibility of infection.
