Why did allergic cough appear?
Modern medicine believes that allergic cough's disease is due to abnormal immune response caused by external environmental factors, which leads to imbalance of Th 1 and Th2 immune response. The main immunopathological feature is the infiltration of cells expressing Th2 cytokines in tissues. The main reasons for allergic cough are:
1, heredity and physique: According to statistics, when both parents have allergic symptoms, the attack rate is as high as 90%, while when only one parent has allergic symptoms, the attack rate is sometimes as high as 70%, so hereditary allergic cough plays a very important role in the etiology.
2. Environmental changes: The fluttering of pollen, the amount of dust, the level of temperature and humidity, the change of heat and cold, the stimulation of sunlight or ultraviolet rays, and whether there is special body odor may all induce allergic cough.
Infection: sometimes it is good, but due to upper respiratory tract infection, it may be caused by virus or bacteria, which stimulates tissue cells and produces allergic reactions.
4. Foods with allergens: such as eggs, milk, wine, peppers, cabbage, seafood, etc. Even ice products are possible.
How is allergic cough treated?
Step 1: Try to stay away from allergens.
Dust mites, dermatophagoides farinae and molds are the three most common allergens. At home, first of all, try to keep it dry, not particularly wet, because if children come into contact with mold on the ground, the incidence of rhinitis is higher. Also, the bedding at home should be cleaned frequently, not the bed. Minimize the shaking and sweeping action, and shake off the dust mites at home during the shaking. In addition, if you are allergic to some fur, you must put away your hair pads, carpets, mattresses and pillows at home to reduce allergens at home. In addition, parents should keep allergic children away from the grass, and at the same time, the temperature difference in autumn is large, so they should pay attention to keeping their children warm and cold. Of course, it is not easy to completely avoid allergens in life.
Step 2: Patients with mild symptoms can choose medication.
You can usually prepare some anti-allergic drugs at home. Oral antihistamines (loratadine tablets, Ebastine Tablets, Cetirizine Tablets, etc. ) or leukotriene receptor antagonist (children can choose montelukast sodium chewable tablets) is the first choice.
Drug therapy can usually achieve good results in a short time, but repeated application or ineffective or serious adverse reactions can easily lead to obesity, decreased resistance and other problems.
Step 3: It is necessary to adjust immunotherapy appropriately.
Compared with the "symptomatic treatment" of drugs, regulatory immunotherapy is "etiological treatment", and its curative effect lies in solving immune overreaction, reducing serum IgE antibody and reducing allergic reaction.
In the International Immunotherapy or Radical Measures for Allergic Cough and Asthma in Children, it is argued that when allergic diseases occur, such as allergic eczema, urticaria, recurrent allergic rhinitis and recurrent allergic cough and asthma in children, the immune response in the human body will reduce the number of TH 1 cells. Stimulated by allergens, many cytokines, such as increased IgE production and eosinophilia, are constantly produced, which promotes the immune response to TH2 pathway and forms humoral immune response. Children with asthma in allergic cough can be supplemented with an active antiallergic probiotic component-Xinminkang Probiotics, which can participate in the regulation of immune cytokines. This rare probiotic with antiallergic activity can promote the secretion of interferon in vivo to regulate TH 1 immune response and resist immunoglobulin IgE. By enhancing the TH 1 immune response of immune cells to regulate TH2 immune response which is overreacted due to allergy, children's anti-allergic ability can be improved. This safe intervention of Xinmin Kang probiotic antiallergic immunity in regulation therapy can greatly reduce or shorten the course of treatment of antiallergic western medicine, and regulate immunity to reduce allergy.
Step 4: Daily preventive health care
Studies have found that more contact with nature and regular physical exercise can resist allergies;
Healthy diet (eat more fresh fruits and vegetables) can resist allergies;
Drink plenty of water and eat foods rich in vitamin C. Vitamin C can maintain immune function, inhibit histamine production in the body, improve capillary permeability and relieve symptoms.
