Stomach flatulence and frequent urination may be caused by drinking a lot of water or eating too much water-rich food, or urinary system diseases. If the patient drinks a lot of water in a short period of time or eats more water-rich fruits and foods, indigestion and other conditions may occur, resulting in stomach bloating, abdominal distension, frequent urination, etc. This is a normal physiological phenomenon. If the patient has stomach bloating and frequent urination without drinking and eating, it may be caused by inflammation of the urinary system, such as urethritis, etc., and the patient may show symptoms such as increased urination, small amount of urine, and abdominal bloating and discomfort. Patients who do not get better from long-term gastric distension and frequent urination should go to the hospital in time for examination and treatment under the guidance of the doctor to avoid delaying the condition.
