Introduction
Abdominal pain generally refers to stomachache. Abdominal pain after overeating may be caused by indigestion, intestinal flora imbalance, chronic gastroenteritis, irritable bowel syndrome, duodenal ulcer, or other reasons. It is recommended to seek proper medical treatment promptly. If the pain is severe, it is advisable to go to the relevant department of a hospital for a comprehensive examination and receive standardized treatment to relieve symptoms.

Abdominal pain generally refers to stomachache. Abdominal pain after overeating may be caused by indigestion, intestinal flora imbalance, chronic gastroenteritis, irritable bowel syndrome (IBS), duodenal ulcer, or other reasons. It is recommended to seek timely and proper medical treatment.

1. Indigestion

This may occur when consuming excessive amounts of food, leading to poor digestion due to insufficient secretion of digestive juices. Undigested food accumulates in the stomach, causing discomfort such as nausea and constipation. Under a doctor's guidance, medications such as multienzyme tablets, compound gentian and sodium bicarbonate with sugar-coated pepsin tablets, or gentian and sodium bicarbonate tablets can be used to aid digestion and improve symptoms.

2. Intestinal Flora Imbalance

This condition results from an imbalance in gut bacteria. Consuming large amounts of food at once increases digestive burden and reduces digestive function, leading to excessive food stagnation and fermentation, which may cause abdominal pain and bloating. As prescribed by a physician, medications such as compound digestive enzyme capsules, pancreatin capsules, or lactase tablets may help improve the condition.

3. Chronic Gastroenteritis

Chronic gastritis often leads to weakened gastric motility. Overeating prolongs gastric emptying time, and during food breakdown, irritation to the stomach lining may trigger gastric muscle spasms, resulting in abdominal pain and diarrhea. Following medical advice, medications such as clarithromycin tablets, bismuth potassium citrate capsules, or omeprazole magnesium enteric-coated tablets can help control the condition.

4. Irritable Bowel Syndrome (IBS)

Common triggers for IBS include stress and dietary irritants. Eating too much can further increase intestinal sensitivity and disrupt normal intestinal motility, causing nausea, pain, and other discomforts. Under medical guidance, antispasmodic drugs such as scopolamine patches, bromoscopylamine tablets, or belladonna tablets may be used to relieve pain.

5. Duodenal Ulcer

Excessive food intake stimulates increased gastric acid secretion and faster intestinal motility, which can significantly irritate the ulcer site, causing intense pain that typically worsens after eating. As advised by a doctor, gastric mucosal protectants such as ranitidine hydrochloride tablets, colloidal bismuth pectin capsules, gastric mucin capsules, or vitamin U belladonna aluminum capsules may help alleviate symptoms.

If the pain is severe, it is advisable to promptly visit the appropriate department at a hospital for comprehensive evaluation and proper treatment to relieve symptoms.

Conditions that can be relieved are mostly mild to moderate abdominal pain caused by inflammation or spasms, such as primary dysmenorrhea (accompanied by abdominal bloating and cramping pain) or mild inflammatory abdominal pain due to gastroenteritis.

Can stomach pain cause appendicitis?
In general, whether stomach pain causes appendicitis depends on the specific circumstances. Stomach pain caused solely by conditions such as gastritis or gastric ulcers usually does not lead to appendicitis. However, in some rare cases, early appendicitis may initially present as stomach pain, which can easily be confused with gastric issues; therefore, careful differentiation is necessary. It is important in daily life to maintain regular eating habits, avoid overeating or consuming spicy and irritating foods, and reduce factors that may cause stomach discomfort or trigger appendicitis.
