Sweet mouth should be based on the cause of the disease to determine what western medicine to take. People feel that sweet mouth is caused by physiological factors or pathological factors. It is recommended to go to the hospital for examination to clarify the cause of sweet mouth and treat the cause. 1. Physiological factors: after eating too many sweets and drinks, people will experience the phenomenon of sweetness in the mouth, which is normal and does not need to be disturbed. It is recommended to choose light and easy-to-digest food and eat more vegetables and fruits in moderation. 2. Pathological factors: people due to improper diet, resulting in gastrointestinal tract dysfunction, triggered by a variety of gastric digestive enzyme secretion disorders (such as increased salivary amylase secretion, etc.), will trigger sweet mouth. It is recommended to take hypoglycemic drugs (e.g., acarbose, etc.) under the guidance of a doctor. For people with gastrointestinal dysfunction, it is recommended that they take medicines to promote gastrointestinal dynamics (such as mosapride, etc.) and medicines to protect gastric mucosa (such as magnesium alumina carbonate, etc.) reasonably under the guidance of doctors. If necessary, go to the hospital for treatment.
