Stomach discomfort after eating watermelon on an empty stomach may be caused by watermelon being too cold, gastroenteritis and gastric ulcer.
1. Watermelon is too cold: if you eat iced watermelon on an empty stomach, it causes the gastrointestinal tract to be cooled, which stimulates the vasoconstriction of the blood vessels distributed on the mucous membrane of the gastrointestinal tract, resulting in insufficient blood supply to the gastrointestinal tract, and then you will experience discomfort.
2. Gastroenteritis: Because the mucosa of the gastrointestinal tract is repeatedly stimulated by inflammatory factors, it becomes sensitive, and when you eat watermelon on an empty stomach, the large amount of juice contained in the watermelon stimulates the mucosa of the gastrointestinal tract, thus causing discomfort.
3. Gastric ulcer: eating watermelon on an empty stomach stimulates the gastric mucosa to secrete gastric acid, which can cause stomach discomfort when it stimulates the ulcer surface on the gastric mucosa.
If you have an upset stomach after eating watermelon on an empty stomach, you must go to the hospital in time to find out the cause of the disease and actively cooperate with the professional doctor’s treatment.
