Tips to quickly stop coughing at night lack scientific evidence and are not true. There are many reasons for coughing at night, such as cough variant asthma, cardiac insufficiency, gastroesophageal reflux disease. 1. Cough variant asthma: a special type of asthma, mainly manifested as irritating dry cough, mostly at night and early morning episodes, without obvious wheezing, shortness of breath and other symptoms. Inhaled glucocorticoids (e.g. budesonide) combined with bronchodilators (e.g. salbutamol) are recommended. 2. Cardiac insufficiency: the night cough is mainly caused by the change of body position, which leads to blood stagnation in the lungs, causing pulmonary stasis and edema, thus causing the night cough, which can be alleviated by adopting the sitting position. 3. Gastroesophageal reflux disease (GERD): when lying down, acidic reflux material may reflux to the pharynx, stimulate the pharynx and trachea, and cause nighttime coughing, pharyngeal discomfort and other symptoms. Coughing can be reduced by inhibiting gastric acid secretion such as omeprazole and promoting gastric motility such as domperidone. There are many other reasons for coughing at night, you should go to the hospital in time, to clarify the cause of the disease, under the guidance of the doctor, to avoid delaying the condition. The drugs appearing above also need to be administered under the guidance of a doctor.
