What Causes Stomach Pain After Eating Watermelon?

        Common causes of stomach pain after eating watermelon include spleen-stomach deficiency-cold, gastric chilling, gastric inflammation, or unclean watermelon.

1. Spleen-Stomach Deficiency-Cold

In patients with spleen-stomach deficiency-cold, symptoms such as epigastric pain and cold intolerance are common. Watermelon is a cold-natured food with high water content; consuming it may excessively chill the gastrointestinal tract, irritate the gastric mucosa, trigger excessive gastric acid secretion, and exacerbate these symptoms—thus leading to stomach pain after eating watermelon.

2. Gastric Chilling

Due to its cold nature, excessive consumption of watermelon can cause gastric chilling and stimulate gastric smooth muscle, potentially inducing smooth muscle spasm and resulting in paroxysmal abdominal pain. In such cases, stomach pain after eating watermelon is also commonly observed.

3. Gastric Inflammation

If a patient suffers from gastric inflammatory conditions such as gastric ulcers or chronic gastritis, ingesting watermelon may directly irritate existing gastric lesions, causing persistent epigastric pain.

4. Unclean Watermelon

If the watermelon is contaminated and proper hygiene is not observed during consumption, pathogen infection may occur, leading to acute gastroenteritis—and consequently, stomach pain after eating watermelon.
