A child’s dry cough without sputum all the time may be caused by a foreign body or inflammation that irritates the respiratory tract. Cough is one of the more common clinical respiratory symptoms, and diseases such as laryngitis and tonsillitis are often accompanied by a dry cough without sputum all the time, which may affect the child’s rest and even induce serious complications. 1. Foreign body: The child accidentally ingests smaller items such as toy parts, which are not detected in time, stimulating the respiratory tract and causing a dry cough all the time. It is recommended to go to the hospital and remove the respiratory foreign body under the operation of professionals. 2. Inflammation: Inflammation commonly caused by upper respiratory tract infections, including laryngitis, rhinitis, colds, tonsillitis, etc. In addition to dry cough without sputum all the time, children often have a sore throat, nasal congestion, runny nose, tonsil pain, enlarged tonsils, etc. You can go to the hospital to combine clinical examination, and symptoms for a comprehensive analysis to determine the cause and treatment; 3. Gastroesophageal reflux: It may be due to the child’s underdeveloped gastrointestinal function, or long-term high-fat diet and other factors that lead to frequent gastroesophageal reflux in children. In addition to having your child change poor eating habits, you can also take medications such as proton pump inhibitors, stomach acid inhibition, and mucosal protectors to neutralize stomach acid as prescribed by your doctor for treatment. In addition to the above causes, allergies and cold air irritation can also cause a child to have a dry cough without phlegm. If the dry cough is severe, it is recommended to go to the hospital in time to clarify the cause and treat it earlier to avoid delaying the effect of treatment and making the condition worse.
