Stomach pain after meal

As modern diet is better and people's eating habits are becoming more and more irregular, stomach pain after meals is a common phenomenon. Try not to exercise right after a meal; wait an hour and a half before doing any activity. First of all, stomach pain may be caused by gastroptosis or enteritis. If it is more serious, it may be nausea and vomiting accompanied by stomach discomfort. The best time to exercise is to walk around one and a half hours after a meal.

1. Acute gastritis

The onset is acute and the clinical symptoms vary in severity. The most common is acute simple gastritis, the main symptoms of which are upper abdominal pain, abdominal distension, belching, loss of appetite, nausea, vomiting, etc. Those caused by Salmonella or Staphylococcus aureus toxins are often accompanied by diarrhea, fever, and even dehydration and shock. Acute erosive hemorrhagic gastritis may cause vomiting of blood and black stools. The main clinical manifestations of acute suppurative gastritis are systemic sepsis and acute peritonitis. The symptoms of acute corrosive gastritis are the most obvious, manifested as severe pain in the mouth, throat, behind the sternum, and upper abdomen after swallowing corrosives, accompanied by nausea, vomiting, and even vomiting blood. The mucous membranes of the lips, mouth, and throat can produce caustic scabs of different colors, which help to identify various corrosive agents.

2. Chronic gastritis

The clinical manifestations of different types of gastritis may vary, but the symptoms lack specificity, and the severity is often inconsistent with the severity of the lesion. Some patients may be asymptomatic.

(1) Upper abdominal pain or discomfort Most gastritis patients experience upper abdominal pain or discomfort. Most upper abdominal pain is irregular and has nothing to do with diet. The pain is generally diffuse upper abdominal burning pain, dull pain, bloating, etc.

(2) Upper abdominal distension and early satiety Some patients experience abdominal distension, especially a noticeable feeling of fullness after a meal. It is often caused by food retention in the stomach, delayed emptying, and indigestion. Early satiety refers to a feeling of fullness soon after eating despite having a clear sense of hunger, and a significant reduction in food intake.

(3) Belching, acid reflux, and nausea Belching indicates an increase in gas in the stomach, which is discharged through the esophagus, temporarily relieving upper abdominal fullness. Acid reflux is caused by increased gastric acid secretion.

(4) Other severe atrophic gastritis patients may have weight loss, glossitis, and diarrhea; autoimmune gastritis patients may have anemia.

3. Peptic ulcer is a common digestive tract disease that can occur in the esophagus, stomach or duodenum. It can also occur near the gastrojejunal anastomosis or in the Meckel diverticulum containing gastric mucosa. Upper abdominal pain is the main symptom of this disease. It is mostly located in the upper abdomen, but may also appear in the left upper abdomen or behind the sternum or xiphoid process. It often presents as dull pain, bloating, or burning pain. The pain of gastric ulcer usually occurs within 1 hour after a meal, gradually eases after 1 to 2 hours, and the above rhythm returns after the next meal. Some patients may be asymptomatic, or may have complications such as bleeding and perforation as the first symptoms.
