There are many reasons for more gas and stomach discomfort in the afternoon, usually caused by disorders of intestinal flora, indigestion, enteritis and cholecystitis. 1. Intestinal flora disorders: intestinal flora disorders can cause intestinal dysfunction and produce more gas, leading to abdominal discomfort. 2. Indigestion: Due to insufficient secretion of digestive enzymes or slow intestinal peristalsis, it is difficult to digest some food, and symptoms such as abdominal distension, abdominal pain, and excessive flatulence may occur. 3. Enteritis: Bacterial infection in the intestinal tract can destroy the intestinal flora, resulting in abdominal pain, abdominal distension, and excessive flatulence. 4. Cholecystitis: When cholecystitis occurs, the discharge of bile decreases, the ability to break down food fats is weakened, and a large amount of fat accumulates in the intestines, which can also lead to increased gas, and cholecystitis itself can also show symptoms of abdominal discomfort. If the above symptoms continue to be unrelieved, it is recommended to go to the hospital in a timely manner, under the guidance of a professional doctor to clarify the cause of the disease, so as to avoid delaying the condition.
