What causes stomach pain after eating?

The term "stomach" may refer to the abdomen. Generally, abdominal pain after eating could be caused by improper diet, indigestion, gastritis, cholecystitis, gastric ulcers, and other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Improper diet: Eating too quickly or consuming excessively cold or raw foods may irritate the gastrointestinal mucosa, leading to gastrointestinal dysfunction and subsequent abdominal pain. It is advisable to chew food thoroughly and eat slowly, avoiding cold or raw foods such as ice cream and popsicles.

2. Indigestion: This may be related to weakened gastrointestinal motility or insufficient gastric acid secretion. After eating, food may not be fully digested and absorbed, remaining in the gastrointestinal tract and causing symptoms such as abdominal pain and bloating. Patients are advised to take medications such as Baohe Pills, Jianwei Xiaoshi Tablets, or Simo Tang Oral Liquid as directed by a physician to alleviate symptoms.

3. Gastritis: This is usually associated with long-term improper diet or Helicobacter pylori infection. The patient's gastric mucosa may become damaged, and gastric acid secretion may increase after eating, which can irritate the injured mucosa and lead to symptoms such as abdominal pain, nausea, and vomiting. Patients are advised to take medications such as Compound Rennet Capsules, Potassium Citrate Bismuth Tablets, or Colloidal Fruit Pectin Bismuth Capsules as prescribed.

4. Cholecystitis: This may be related to gallstones or infections. When inflammation occurs in the gallbladder wall, bile secretion and excretion may be obstructed. After eating, especially fatty foods, the gallbladder may be stimulated to contract, thereby exacerbating inflammation and causing abdominal pain. Patients are advised to strictly follow medical instructions and use medications such as Cefixime Capsules, Minocycline Hydrochloride Capsules, or Cefixime Granules to relieve symptoms.

5. Gastric ulcer: This may be associated with long-term irregular eating habits, excessive stress, and other factors. Patients often experience abdominal pain after meals, accompanied by symptoms such as heartburn and acid reflux. It is recommended that patients use medications such as Esomeprazole Magnesium Enteric-Coated Tablets, Rabeprazole Sodium Enteric-Coated Tablets, or Lansoprazole Tablets under the guidance of a doctor.

It is recommended to maintain good dietary hygiene, avoid overeating, and consume moderate amounts of easily digestible, nutritious foods such as noodles and milk, which may aid in recovery.
