Feeling no fullness after eating, and getting hungry again shortly afterward.

Feeling hungry soon after eating without a sense of fullness may be caused by factors such as improper diet, gastritis, diabetes, and other conditions. Treatment generally depends on the specific underlying cause and should be conducted under a doctor's guidance. A detailed analysis is as follows:

1. Improper Diet

If insufficient food is consumed in daily life, it may lead to hunger shortly after meals. This condition can usually be improved by moderately increasing food intake.

2. Gastritis

Consuming contaminated food may lead to Helicobacter pylori infection, triggering gastritis. Inflammation of the gastric mucosa can stimulate feelings of hunger. Patients may take medications orally as directed by a physician, such as omeprazole enteric-coated tablets or sucralfate chewable tablets.

3. Diabetes

Insufficient insulin secretion in the body may lead to diabetes, causing the body to lack energy and resulting in persistent hunger. Patients typically need to promptly take prescribed oral medications as directed, such as metformin hydrochloride sustained-release tablets or Jiangtangning capsules.

In addition to the above causes, this symptom may also result from hyperthyroidism, gastric ulcers, hypoglycemia, and other conditions. It is recommended that patients seek timely medical evaluation upon experiencing discomfort to avoid delaying recovery.
