Stomach discomfort and profuse secretion of saliva are caused by weak spleen and stomach, food irritation, gastroesophageal reflux and other factors. In Chinese medicine, the spleen is the main regulator, and when the human body has a weak spleen and stomach, it promotes the function of the intestines and stomach, and the digestion and decomposition of food will be affected, which will cause the symptoms of stomach discomfort. At the same time, it is unable to regulate the water transportation in the body, so it will lead to the secretion of saliva more. Daily diet should try to avoid eating too spicy, stimulating food, such as chili peppers, onions, garlic, this kind of food into the stomach will cause stimulation of the mucous membrane of the stomach wall, which will cause contraction of the wall of the stomach, resulting in pain in the stomach, the pain salivary glands will be stimulated, which will lead to an increase in salivary secretion. Gastroesophageal reflux is mainly caused by excessive secretion of gastric acid and reflux of food in the stomach. Due to the excessive secretion of gastric acid, the gastric mucosa will be damaged, resulting in acid reflux, heartburn, burning and pain. As the gastric acid will damage the esophageal mucosa, it will cause the salivary glands to be stimulated, which will also cause increased salivary secretion.
