What should I do if I have stomach pain after eating leftover cold watermelon?

Abdominal pain after consuming leftover chilled watermelon requires targeted interventions—such as pharmacological treatment, physical therapy, and dietary adjustments—based on the underlying cause.

1. Pharmacological Treatment

If abdominal pain following consumption of leftover chilled watermelon is caused by acute gastroenteritis and symptoms are severe, antispasmodic medications—such as belladonna or atropine—may be prescribed under a physician’s guidance to inhibit intestinal smooth muscle spasm and relieve pain. If diarrhea accompanies the abdominal pain, adjunctive agents such as montmorillonite or diphenoxylate may be used to slow intestinal motility and alleviate diarrhea.

2. Physical Therapy

In cases where indigestion causes mild abdominal pain after eating leftover chilled watermelon, gentle abdominal massage or local abdominal heat application may help enhance intestinal motility and improve abdominal blood circulation, thereby alleviating symptoms.

3. Dietary Adjustment

If abdominal pain results from cold-induced irritation, symptom relief can be achieved by drinking moderate amounts of warm water and maintaining a light, soft, easily digestible diet to reduce the digestive burden on the intestines.
