Diarrhea after eating chilled watermelon is often caused by acute gastroenteritis due to eating cold and bacterial food, and should be relieved by general treatment, antidiarrheal, rehydration and anti-infection.
1. General treatment: patients should rest as much as possible, pay attention to abdominal warmth, drink plenty of warm water and hot water, eat small meals, avoiding the intake of greasy, irritating food.
2. Antidiarrhea: If the patient has a lot of diarrhea that is difficult to relieve, he/she can take antidiarrheal drugs such as montelukast and loperamide.
3. Rehydration: If the patient is dehydrated due to diarrhea, oral rehydration salts can be taken for mild to moderate cases, while intravenous rehydration is needed for severe cases.
4. Anti-infection: If the acute gastroenteritis is caused by bacterial infection, antibiotic treatment is needed.
If the patient’s diarrhea is not relieved or even aggravated after home treatment, he should go to the hospital in time.
