Common causes: Foreign strains of Escherichia coli produce toxins that prevent intestinal water absorption.; Salmonella and Shigella bacteria cause true dysentery.; Giardia parasite from contaminated water is another cause..

- For non-bacterial diarrhea: 3 tablespoons of raw unprocessed wheat bran daily in fruit juice has been shown to provide relief.

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Prevention while traveling: drink only acidic drinks (fruit juice) or sealed bottled/carbonated beverages. Avoid uncooked vegetables, salads, unpeeled fruits, ice cubes, and anything prepared with unpurified water. Boil water for 3–5 minutes. Make sure utensils are washed with purified water. When ill: stick to cooked simple foods — rice, bananas, cooked grains, clear broth — and stay very well hydrated.
⚖️ Good to know
- Warning signs that indicate something more serious: abdominal bloating with vomiting and pain (may indicate colitis, appendicitis, or intestinal obstruction)
- black or red stools (bleeding or parasitic infection)
- white or pale stools (liver disease)
- fever with diarrhea (serious infection). Amoebic dysentery is particularly dangerous in Mexico and Central America — do not ignore it. The commercial drug Entero-Vioform, sometimes given to travelers, is banned in Japan and Sweden due to risk of severe nerve and eye damage — avoid it.
🩺 When to see a doctor
