Bloating and drooling can be caused by indigestion, chronic gastritis, gastrointestinal dysfunction and so on. 1. Indigestion: If patients often eat irregularly or eat too much, it is easy to cause the burden of the stomach and intestines to increase, resulting in slowing down the peristalsis of the stomach, food stagnation in the stomach, which will lead to gastric bloating and drooling. 2. Chronic gastritis: if affected by bile reflux, Helicobacter pylori infection and other factors, resulting in gastric mucosal damage, erosion, leading to decreased digestive function, which can also cause gastric bloating, acid reflux, drooling and other symptoms. 3. Gastrointestinal dysfunction: If the patient is in a situation of long-term tension, anxiety and stress, it is easy to cause the cerebral cortex to innervate the gastrointestinal nerves, as well as the nerves of the salivary glands to be disturbed, so that the digestive function is affected, resulting in gastric distention, drooling, nausea, vomiting and other symptoms. It is recommended that patients go to the hospital in time, under the guidance of the doctor, according to the patient’s specific condition, to take targeted treatment.
