Children who always clear their throats and make uttering noises may be related to non-disease factors such as dry environment and greasy diet, but may also be associated with lesions such as childhood tics, colds or nasopharyngeal inflammation. If it occurs frequently, you need to visit a hospital promptly to identify the cause. I. Non-disease factors: 1. Environmental factors: More dust in the air or too dry indoors, while babies drink too little water, can lead to throat discomfort and frequent throat-clearing uttering sounds. Parents should supervise their children to drink more water to prevent discomfort caused by a dry throat, and properly turn on the humidifier at home to keep the house moist. 2, dietary factors: Some children love to eat sweets, fried food, and drink all kinds of drinks, and because the proportion of sugar and fat in food is high, it will lead to more saliva secretion in the mouth and a sticky feeling, and then children will clear their throats and make uttering sounds. Parents should pay attention to the diet, give children more fresh vegetables and fruits, and eat less snacks. Second, disease factors: 1, children’s tics: habitual throat clearing is one of the symptoms of children’s tics. If a child clears his or her throat at a high frequency for a long time, with abnormal pronunciation, but no other uncomfortable symptoms, you need to go to the hospital for a consultation. If the child is diagnosed with tic disorder, he or she needs to take calcium and vitamin D supplements as prescribed by the doctor. Parents should often remind to correct the child’s behavior, but avoid criticism and scolding to avoid causing psychological trauma to the child; 2. Cold: cold can cause sore throat, phlegm, itchy throat and other uncomfortable symptoms, which can lead to throat clearing all the time, and symptomatic treatment drugs can be taken under the guidance of the doctor, such as acetaminophen for high fever and acetaminophen for sore throat. If the cold is healed, the throat clearing will stop. 3. Nasopharyngeal diseases: If pharyngitis, rhinitis or sinusitis occurs, there will be a foreign body sensation in the throat and the discomfort will be relieved by clearing the throat. Parents are advised to take their children to the ear, nose and throat department. Antibiotic treatment, such as penicillin, is available for acute pharyngitis, and gargling with compound borax solution and furacilin solution is available for chronic pharyngitis. Nasal sprays, such as budesonide nasal spray, can be applied for rhinitis or sinusitis.
