What causes abdominal bloating and pain after eating?

Abdominal bloating and pain after eating may be caused by physiological factors or pathological conditions such as insufficient gastric motility, gastric ulcers, etc. The specific analysis is as follows:

1. Physiological Factors

If the food consumed during meals is high in carbohydrates, excessive hydrogen sulfide gas may be produced during acid digestion in the stomach, leading to bloating and abdominal pain after eating. Symptoms can be relieved through clockwise abdominal massage and improving dietary habits.

2. Pathological Factors

1) Insufficient Gastric Motility

Insufficient gastric motility may result from disorders of gastric secretory function, significant emotional fluctuations, etc., causing food to fail to digest and absorb properly after entering the stomach. This delayed gastric emptying leads to the aforementioned symptoms. Treatment may include medications such as sulpiride tablets or metoclopramide tablets, taken as directed by a physician.

2) Gastric Ulcer

Helicobacter pylori infection is a primary cause of gastric ulcers. When the stomach lining is eroded by gastric acid, ulceration occurs, resulting in impaired gastrointestinal function and the associated symptoms. Patients may take medications such as sucralfate chewable tablets or bismuth potassium citrate capsules as prescribed by a doctor.

In addition, postprandial abdominal bloating and pain could also be caused by intestinal spasms, chronic gastritis, duodenitis, duodenal ulcers, intestinal obstruction, or gastric perforation. It is recommended to maintain a balanced and reasonable diet in daily life.
