Sleeping cough is due to lying down at night while sleeping, the abdominal organs and septal muscles are elevated, resulting in restricted lung diastole, coupled with high vagal excitation, all of which can lead to increased coughing. Consider the possibility of the following diseases: i. Allergic asthma, also known as cough variant asthma, is mainly a dry cough, which requires the addition of wheezing medication for relief. Chronic laryngitis. Common bronchial and lung infections. IV. Cardiac insufficiency, which mainly occurs in patients with combined organic heart disease, such as coronary heart disease, pulmonary heart disease, congenital heart disease, heart valve disease, etc. V. Reflux esophagitis, which is easily overlooked, is mainly gastric juice, which flows back into the esophagus at night due to lying down, and in severe cases, enters the trachea, bronchi and lungs through the pharynx, leading to coughing, and general antibiotics and other treatments are ineffective. Gastroscopy reveals changes in the esophageal mucosa such as congestion, erosion and ulceration. There may be burning and painful sensation behind the sternum at the same time, so it is recommended to go to the hospital for examination.
