Most people get acute diarrhea and recover within a few days. The real risk is dehydration, not the stool itself. Know what helps, what doesn’t, and when to call a doctor.
Common causes include viruses (norovirus, rotavirus), food poisoning (bacteria like Salmonella or E. coli), medication side effects, and travel-related bugs. Onset is usually sudden — one meal or a day after exposure — and symptoms are loose stools, cramps, sometimes vomiting or fever.
Start with fluids. Sip oral rehydration solutions (ORS) if you can — they replace salts and sugar your body loses. If ORS isn’t available, mix 1 liter of water with 6 teaspoons sugar and half a teaspoon salt as a temporary option.
Adults should aim for small, steady sips: about 200–400 mL after each loose stool. For babies and young children use WHO or pediatric ORS and follow package directions. If a baby is breastfeeding, keep breastfeeding.
Eat when you can. Plain foods that are gentle on the gut help: bananas, rice, plain toast, and boiled potatoes. Avoid high-fat, spicy, or very sugary foods until you’re better. Skip dairy for a few days if milk makes symptoms worse.
Over-the-counter options can help symptoms. Loperamide (Imodium) reduces stool frequency in adults and is useful for short-term relief if you’re not febrile and don’t have bloody stools. Bismuth subsalicylate (Pepto-Bismol) can ease nausea and stool frequency. Don’t use loperamide if you suspect severe bacterial infection (high fever, bloody stool) or if a child has certain illnesses — check with a clinician first.
Call a doctor right away if you have any of these: a fever over about 38.5°C (101.3°F), blood in the stool, severe belly pain, signs of dehydration (dry mouth, very little urine, dizziness), or diarrhea lasting more than 48–72 hours. For infants, older adults, and people with weakened immune systems, seek care sooner — they dehydrate faster and infections can be more serious.
If you’ve recently traveled to a high-risk area, taken antibiotics, or eaten undercooked meat or raw shellfish, tell your provider — those details change testing and treatment. Antibiotics are only needed for specific bacterial causes; they won’t help viral cases and can sometimes make things worse.
Most acute diarrhea clears with fluids and simple care. Watch for warning signs, keep sipping ORS, and rest. If you’re unsure, a quick call to a clinic can save a lot of worry.
During holidays and special occasions, managing acute diarrhea can be quite challenging. In my experience, it's essential to stay hydrated by drinking plenty of water, clear broth, or oral rehydration solution. I also recommend eating a bland diet, including foods like bananas, rice, applesauce, and toast, to help the digestive system recover. Over-the-counter medication like Imodium can also be helpful in controlling diarrhea symptoms. Lastly, it's important to practice good hygiene by washing hands frequently to avoid spreading the infection to others.
