Quick Answer
Most loose motions are short-lived and settle with hydration and rest. If diarrhea lasts beyond 5 days, has blood, fever or severe pain, or causes dehydration, it needs specialist evaluation. Dr. Anando Sengupta investigates and treats persistent diarrhea with stool tests, blood work and colonoscopy when indicated.
Common causes of loose motions
- Viral gastroenteritis — rotavirus, norovirus, adenovirus
- Bacterial infections — E. coli, Salmonella, Shigella, Campylobacter
- Parasitic — Giardia, Entamoeba histolytica
- Food poisoning — staphylococcal toxin, Bacillus cereus
- Traveller's diarrhea — usually enterotoxigenic E. coli
- Antibiotic-associated — including C. difficile colitis
- Functional / IBS
- Lactose / fructose intolerance
Home care for mild loose motions
- Drink ORS (one packet in 1 litre of clean water) — 250 ml after every loose stool
- Continue eating — banana, boiled rice, curd, plain toast, khichdi
- Avoid milk, oily food, raw salad, fruit juice, alcohol
- Loperamide 2 mg after each loose stool, max 8 mg/day — only if no fever or blood
- Probiotics may help shorten the illness
See a doctor urgently if: blood or pus in stool, high fever (>39 °C), severe abdominal pain, >6 stools/day, dehydration signs, recent antibiotics, immunocompromised state, or no improvement after 5 days.
