What causes stomach pain when hungry?

Generally, stomach pain triggered by hunger may be caused by gastric acid irritation, gastritis, gastric ulcer, duodenal ulcer, cholecystitis, or other conditions. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Gastric acid irritation: When fasting for prolonged periods, the concentration of gastric acid in the stomach increases, which may irritate the gastric mucosa and cause stomach pain. The discomfort typically subsides after eating, and usually does not require concern.

2. Gastritis: Gastritis refers to inflammation of the gastric mucosa, which may be caused by infections, improper diet, long-term use of certain medications, or other factors. Symptoms include abdominal bloating, belching, nausea, and loss of appetite, and may also involve the aforementioned pain. Patients can take medications such as domperidone tablets, ranitidine hydrochloride capsules, or omeprazole enteric-coated capsules under medical guidance.

3. Gastric ulcer: In patients with gastric ulcers, there is damage to the gastric mucosa. During hunger, excessive gastric acid secretion directly irritates the damaged area, causing pain. Appropriate medications prescribed by a doctor—such as rabeprazole sodium enteric-coated tablets, cimetidine tablets, or amoxicillin capsules—can help improve symptoms.

4. Duodenal ulcer: A classic symptom of duodenal ulcer is fasting pain—pain becomes evident when hungry and improves after eating. This occurs because excess gastric acid during fasting irritates the damaged area of the duodenum. It is recommended to follow a physician’s instructions and use medications such as lansoprazole tablets, rabeprazole sodium enteric-coated capsules, or colloidal bismuth pectin capsules for treatment.

5. Cholecystitis: In patients with cholecystitis, gallbladder function is impaired and bile secretion becomes abnormal. During hunger, insufficient bile secretion may lead to indigestion and stomach pain. Additionally, cholecystitis may cause biliary colic and other symptoms. Under medical supervision, patients may use medications such as anti-inflammatory and cholagogue tablets, ursodeoxycholic acid tablets, or dl-anisodamine tablets for treatment.

In daily life, it is recommended to maintain a positive mindset, avoid spicy, stimulating, and greasy foods, get adequate rest, and develop healthy lifestyle habits.
