I. Symptoms and characteristics of allergic cough
Children with allergic cough cough for a long time, usually more than 2 months and the reason is unknown; Generally, there is no fever, because there is no source of infection in the body, so the sputum spit out is white foam sputum; Allergic cough often occurs in hot and cold alternation or seasonal alternation. Common symptoms are: children like to rub their eyes and nose and scratch their scalp; Lie down and sweat profusely (commonly known as steamer head); Sleeping restlessly, like to sleep curled up, coughing more violently, breathing more rapidly, and recurring attacks. In allergic cough, cough is the main symptom, but there is no asthma symptom. Allergic cough has three characteristics: three coughs: one before going to bed at night, one after waking up in the middle of the night and one after waking up in the morning. The light person coughs three or five times, and the heavy person coughs like a machine gun, blushing and blushing, and tears and runny nose flow together. Some children can cough for three months in a row, much like the symptoms of whooping cough.
Experts remind: Children who cough repeatedly for more than 1 month should go to the local allergy center to test the airway reactivity in time and look for allergens in order to make a definite diagnosis. Those patients with high IgE or eosinophils in laboratory test results are powerful clinical indicators for the diagnosis of allergic cough.
Second, allergic cough's reason is allergic constitution.
Allergic cough is easy to happen in children with allergic constitution. Allergic constitution refers to the congenital defect of immune function in the body, and the immune response in the body will reduce the number of TH 1 cells. After foreign related antigen substances (pollen, mites, fungi, etc.). ) enter such a human body, and constantly produce a variety of cytokines such as IgE and increased eosinophil production, prompting the immune response to form a humoral immune response to TH2 pathway, resulting in a series of harmful reactions.
On the other hand, most children's allergies are acquired. The better the living conditions, the higher the proportion of children suffering from allergic diseases. Electromagnetic radiation from various household appliances, computers and mobile phones is a major factor causing allergies. Because children aged 3-6 are lively and like curious new things, when they often sing with a microphone, watch TV at close range or get close to the computer, electromagnetic waves will easily enter their bodies, while children's own resistance is lower than that of adults, and their body's adjustment ability after radiation is relatively poor. Therefore, parents should minimize their children's close contact with radiation.
Allergens causing this disease include: inhalation allergens, the most important of which is dust mites inhaled from respiratory tract. About 80% of asthma attacks are related to this mite attached to dust. They often fly in the air, float for a long time and are constantly inhaled by children; Foods that are easy to cause when allergens are ingested include milk, eggs, fish and shrimp, foods containing spices, and wheat foods. Most of them belong to foreign proteins; Contact allergens, including cosmetics, essence, iodine, rubber, plastic toys, etc. Infectious allergens, such as pneumococcus, Haemophilus influenzae, Klebsiella pneumoniae, Staphylococcus aureus, hemolytic streptococcus, adenovirus, respiratory fusion virus, parainfluenza virus, etc. It is the main "culprit" that leads to asthma attacks in children under 5 years old. In addition, children with allergies are often allergic to "cold", and once they encounter cold air or cold air, they will cause allergic attacks.
Third, allergic cough treatment: you can't give your child a cough blindly.
Because allergic cough usually attacks at night or in the early hours of the morning, he usually doesn't cough or rarely coughs during the day. Parents often think that the child is infected with upper respiratory tract or bronchitis caused by a cold, and blindly give the child antibiotics and cough medicine, and the treatment often has no effect or little effect. After a long time, children can develop into typical bronchial asthma. Therefore, it is very important to make a clear diagnosis and conduct standardized treatment in time.
At present, people's concept of treating allergic diseases has gradually changed from the previous symptom treatment to paying attention to the adjustment of allergic constitution. Focus on improving allergic constitution and improving immunity from the root. Modern medical research on microecology has found that a new strain of antiallergic lactic acid bacteria can improve allergic constitution and fully participate in human metabolism, immune development, immune repair and immune response balance. One or more strain compositions represented by Xinmin Kang antiallergic probiotics have the ability of enhancing antiallergic, which is unknown in the prior art, and the method of regulating TH2 immune response which is 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.
Fourth, how to prevent "allergic cough"
Avoid incentives and reduce allergen exposure. When the seasons alternate and the temperature changes suddenly, do a good job of cold prevention and warmth to prevent colds and colds; Stay away from allergens or undergo desensitization treatment; Enhance physical fitness, combine work and rest, and balance nutrition. Do not use carpets, stuffed furniture and stuffed toys; Control the indoor humidity below 50% to control the growth of dust mites and molds.
No pets or flowers at home; Don't lay carpets; Don't let children fall asleep with plush toys; When you take the mat out for use the next summer, don't just scrub it with a wet cloth. It is better to put it in a big bathtub, soak it in boiling water for two hours, and then expose it to the sun to completely kill mites.
We should also pay attention to our diet. The general principle is a delicious, light and nutritious diet. Because irritating food will aggravate cough, so eat less salty, sour and spicy food. Give a warm diet, noodles and soup are good. Do not eat cold food and drinks, and stay away from ice cream, ice cream and iced soda.
