Sourness in the mouth after eating sweets may be caused by digestive system diseases, oral diseases, diabetes and other reasons.
1. Digestive system diseases: If the patient suffers from gastritis and gastric ulcer and other diseases, after eating sweets, the gastric mucosa will secrete too much gastric acid, resulting in heartburn and acid reflux symptoms, which leads to acidity in the mouth after eating sweets.
2. Oral diseases: If the patient has stomatitis and other diseases, after the sweet food enters the mouth, the food residue will mix with the saliva and bacteria in the mouth, resulting in acidity and fermentation, which leads to sourness in the mouth after eating sweets.
3. Diabetes: Usually this kind of patients will have sugar metabolism disorders, and consuming sugary foods may lead to sourness in the mouth.
There are many other possible causes of acidity after eating sweets, and it is recommended that patients actively seek medical attention to clarify the cause of the disease and then standardize the treatment.
