Frequent reflux and acid reflux may be caused by improper diet, chronic gastritis and gastroesophageal reflux disease. Frequent acid reflux may be due to improper diet and irregularity, often eat stimulating food, resulting in excessive secretion of gastric acid and acid reflux symptoms; it may also be due to chronic gastritis, which causes damage to the gastric mucous membrane function, leading to reflux. It may also be due to gastroesophageal reflux disease (GERD), in which the anti-reflux structure and function are impaired and the esophageal clearance is reduced, leading to the occurrence of acid reflux. In addition, long-term smoking and drinking alcohol can also cause stimulation of the gastric mucosa, causing excessive secretion of gastric acid. When acid reflux occurs frequently, there may be other causes, such as stomach tumors, gastric ulcers, you should go to the hospital in time for examination, to clarify the cause of the onset of the disease, and receive further treatment.
