Autumn is a good season for allergic diseases. The incidence of cough variant asthma in children is currently on a significant rise. However, the disease often starts with a cough and does not manifest as wheezing, so children are often misdiagnosed as having upper respiratory tract infections or bronchitis, and treatment is often ineffective or has little effect. Misconceptions about cough variant asthma in children have led to an increasing number of children with the disease turning into typical bronchial asthma, which should be taken seriously by parents. Coughing is an important defense mechanism in the body, as secretions and inflammatory substances in the airways can be expelled from the body with coughing. The presence of cough symptoms indicates that the body may be in a pathological state. Chronic cough in children is usually a cough that lasts for more than 4 weeks and often bothers children and their parents. There are many causes of chronic cough in children, and allergies are an important one. Children often have a chronic cough that is not improved over time. Since coughing usually occurs at night or early in the morning, and usually not during the day or rarely during the day, parents tend to think that their child has a cold or flu and don’t pay much attention to it, or they just give them antibiotics and cough medicine. In fact, the child is suffering from cough variant asthma. Over time, the child can develop into a typical bronchial asthma. Therefore, it is important to have a clear diagnosis and standardized treatment in time. Common symptoms of cough variant asthma: Usually no fever. Spitting of white foamy sputum. Likes to rub the eyes and nose and scratches the scalp. Sweating and restlessness during sleep, preferring to sleep curled up. Mostly coughing, not wheezing. The three main characteristics of cough: coughing at night before going to bed; waking up in the middle of the night; waking up in the morning. Some children can cough for up to three months at a time. The most important thing to do is to eliminate the causes: 1. When the seasons change and the temperature changes suddenly, parents should try to keep their children warm to avoid catching a cold or catching a cold. 2. Avoid foods that can cause allergy symptoms, such as seafood, cold drinks, etc. 3. Don’t keep pets and flowers at home, don’t lay carpets, and avoid contact with pollen, dust mites, oil fumes, paint, etc. 4.Do not let children sleep with long fluffy toys. 5.In bathrooms and basements, dehumidifiers and air filters should be used, and the filters should be replaced regularly. Treatment should be standardized: According to the global standardized asthma treatment program developed by the World Health Organization, a stepwise, graded treatment according to the severity of symptoms should be used. Combined treatment with inhaled hormones, bronchodilation, taking anti-inflammatory and desensitizing drugs, etc. is also advocated, along with Chinese herbal compresses, etc. to treat both the symptoms and the root cause.
