Introduction
The management of stomach pain caused by intense physical activity after meals depends on the underlying cause. Common factors include blood redistribution, indigestion, acute gastroenteritis, gastric ulcers, and intestinal obstruction. It is recommended to seek timely medical attention, undergo appropriate diagnostic tests under a doctor's guidance, and receive targeted treatment based on the specific cause and clinical symptoms to promote recovery.

The management of stomach pain caused by intense exercise after meals depends on the underlying cause, with common factors including blood redistribution, indigestion, acute gastroenteritis, gastric ulcers, and intestinal obstruction.

1. Blood Redistribution

Engaging in intense physical activity immediately after eating may lead to a redistribution of blood flow in the body—for example, more blood flowing to active muscles—resulting in relatively reduced blood supply to the gastrointestinal tract. This can cause gastrointestinal discomfort and abdominal pain, which is generally a normal physiological response. Symptoms can usually be relieved through appropriate rest.

2. Indigestion

Frequent overeating can increase the digestive burden on the gastrointestinal system, leading to indigestion. During exercise, this may trigger excessive spasms of the gastrointestinal tract, causing abdominal pain along with bloating and belching. It is recommended to take medications such as Jianwei Xiaoshi tablets, Compound Pepsin Powder, or Lactase Tablets under medical guidance to enhance gastrointestinal motility and promote recovery.

3. Acute Gastroenteritis

When acute inflammation of the gastrointestinal mucosa is present, intense exercise may increase abdominal pressure, causing intestinal muscle spasms and resulting in severe pain, diarrhea, and bloating. Under medical supervision, antibiotic medications may be used to control inflammation and support recovery. Commonly prescribed drugs include Norfloxacin Capsules, Levofloxacin Hydrochloride Capsules, and Amoxicillin Capsules.

4. Gastric Ulcer

If there are ulcers or erosions in the gastric mucosa, intense exercise may increase intra-abdominal pressure, irritating the ulcer site and causing severe abdominal pain, acid reflux, and bloating. Under a doctor’s advice, medications that protect the gastric mucosa can be used to reduce irritation and improve symptoms. Common options include Lansoprazole Enteric-coated Capsules, Omeprazole Enteric-coated Capsules, and Rabeprazole Sodium Enteric-coated Tablets.

5. Intestinal Obstruction

In individuals with a history of surgery leading to adhesions and intestinal obstruction, vigorous exercise may alter local blood circulation, worsening inflammation and edema, thereby intensifying pain and causing symptoms such as cessation of gas passage and abdominal distension. Prompt medical attention is typically required, and surgical intervention under medical guidance may be necessary to release the adhesions and restore normal bowel function.

When abdominal discomfort occurs, it is advisable to seek timely medical evaluation and proper treatment to prevent serious complications and promote symptom improvement.
