Introduction
Stomach bloating after meals may be caused by improper diet, eating too quickly, indigestion, gastritis, gastric ulcers, or other reasons. If discomfort occurs, it is recommended to seek medical attention promptly. In daily life, it is important to adjust dietary habits by choosing light and easily digestible foods, engaging in moderate physical activity to promote gastrointestinal motility and aid digestion, thereby preventing and relieving post-meal stomach bloating.

Under normal circumstances, postprandial bloating may be caused by overeating, eating too quickly, indigestion, gastritis, gastric ulcers, or other reasons. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:

1. Overeating

Overeating or binge eating, especially consuming excessive oily, spicy, or hard-to-digest foods, places a heavy burden on the stomach and may lead to postprandial bloating. It is recommended to adjust dietary habits by avoiding overeating, chewing food thoroughly, and choosing light, easily digestible meals.

2. Eating Too Quickly

Eating rapidly causes food to enter the stomach without being adequately chewed, increasing the digestive burden on the stomach and often resulting in postprandial bloating. One should slow down during meals, chew food thoroughly, and avoid talking while eating to reduce the amount of swallowed air.

3. Indigestion

Indigestion is mainly caused by gastrointestinal motility disorders or reduced gastric receptive relaxation function. Weakened gastrointestinal function and insufficient secretion of digestive juices cause food to remain in the stomach for prolonged periods and delay gastric emptying, leading to postprandial bloating. It is recommended to take medications such as digestive enzyme tablets, dry yeast tablets, or lactase tablets under medical guidance.

4. Gastritis

Gastritis may result from physical stress, medication-induced injury, alcohol irritation, or other factors. Inflammation and damage to the gastric mucosa impair its motility and prolong gastric emptying time, which may cause postprandial bloating, along with symptoms such as belching, acid reflux, and upper abdominal pain. Patients may follow medical advice to use medications such as famotidine tablets, multienzyme tablets, or omeprazole enteric-coated tablets.

5. Gastric Ulcer

Gastric ulcers are primarily caused by Helicobacter pylori infection or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs). Impaired digestive function in patients can lead to postprandial bloating, possibly accompanied by acid reflux, abdominal pain, and loss of appetite. It is recommended to take medications such as domperidone tablets, mosapride citrate, or rabeprazole sodium enteric-coated tablets as directed by a physician.

In daily life, one should adjust their diet by choosing light and easily digestible foods, engage in moderate physical activity to promote gastrointestinal motility and aid digestion, thereby preventing and relieving postprandial bloating.
