There are many reasons for excess stomach acid and acidosis, mainly two: (1) physiological acidosis. When mental tension, excessive fatigue, emotional upset, cerebral cortical dysfunction, can not be well governed by the nerves of gastric acid secretion, prompting an increase in gastric acid secretion; dietary improprieties, such as too sweet, too salty, too spicy, too acid, too cold, too hot food can stimulate the secretion of gastric acid increase; some coarse grains, sweet potatoes, potatoes, etc., containing a lot of starch, sugar, acid, and so on, will stimulate the stomach to produce a large amount of gastric acid, and is not easy to digest the food In addition, the leftover sugar in the gastrointestinal tract will ferment, which will also trigger the production of pantothenic acid. Certain medications, such as aspirin, reserpine, and prednisone, can also stimulate increased acid secretion. Physiological acidosis does not require special treatment, as long as the elimination of triggering factors can be resolved.　　(2) Pathologic acidosis. Chronic gastritis, gastric or duodenal ulcer disease, etc., can increase gastric acid and often lead to acid reflux. Pathological acidity to find the cause of the disease, you can take drugs to inhibit acidity, such as calcium carbonate, gastroparesis, etc., Chinese medicine Wu Bei San, Zuo Jin Jiu and so on.
