What causes thickening of the gastric wall?

In general, gastric wall thickening may be caused by factors such as acute gastritis, chronic gastritis, gastric ulcers, gastrointestinal polyps, or gastric cancer. A detailed analysis is as follows:

1. Acute Gastritis

The gastric mucosa has a strong regenerative capacity. When the gastric wall is infected by pathogens such as bacteria or viruses, resulting in mucosal damage, the repair process may lead to thickening of the gastric wall.

2. Chronic Gastritis

Chronic gastritis is a long-term inflammation of the gastric mucosa, commonly caused by prolonged acid reflux, infections, or autoimmune responses. The inflammatory stimulation leads to thickening of the gastric wall and may be accompanied by damage and atrophy of the antral glands.

3. Gastric Ulcer

When ulcers develop in the gastric mucosa, they can cause abnormal over-secretion of gastric acid. The gastric tissue's response to excessive acid secretion may result in thickening of the gastric wall.

4. Gastrointestinal Polyps

Gastrointestinal polyps refer to protruding tissues on the stomach or intestinal wall, which can be either benign or malignant. Larger polyps may cause localized thickening of the gastric wall.

5. Gastric Cancer

After the development of malignant tumors in the stomach, tumor infiltration and invasion into surrounding tissues can stimulate the gastric wall, leading to its thickening.

Patients are advised to seek timely medical attention and, under a doctor’s guidance, use medications such as bismuth potassium citrate tablets, colloidal bismuth pectin capsules, rabeprazole sodium enteric-coated tablets, or lansoprazole tablets for treatment. If symptoms are severe, surgical intervention combined with chemotherapy may be recommended under medical supervision. It is also important to maintain healthy lifestyle habits and avoid spicy or irritating foods to promote recovery.
