The severity of nocturnal reflux can be divided into physiological and pathological. Physiological reflux can be relieved by improving diet and lifestyle, while pathological reflux can be relieved by medication. 1. Improve diet and lifestyle: If it is related to diet, such as eating more at night, drinking alcohol, eating more sweets or eating more fried food or high-fat diet, it may aggravate the nocturnal acid reflux, and you should eat a light diet and drink less alcohol and smoke less cigarettes. If acid reflux is more serious when you sleep at night, you can raise the head of the bed appropriately, which can reduce the reflux symptoms. 2. Application of drugs: If it is pathologic, such as reflux esophagitis, acid reflux is more obvious, you can consider taking rabeprazole, pantoprazole, omeprazole and so on. If there are symptoms of severe reflux at night, you should consult a doctor in time for a clear diagnosis.
