Practical guide
What to eat when you have diarrhea
A flexible, evidence-aware guide to eating during recovery.
Seek prompt medical care for blood or black stool, severe pain, confusion, fainting, signs of serious dehydration, or diarrhea in a very young infant. Higher-risk people should contact a clinician sooner.
Quick answer
You usually do not need to stop eating. Drink first, then eat according to appetite. Choose familiar, easy-to-tolerate foods and temporarily reduce anything that clearly worsens urgency, cramping, or bloating.
Key takeaways
- Preventing dehydration is the first priority.
- Most short episodes improve with fluids, rest, and a return to normal food as tolerated.
- Medicines are not right for every person or every cause.
- Persistent or severe symptoms need medical evaluation.
A practical food plan
Start with modest portions. Soup, rice, toast, oatmeal, potatoes, bananas, crackers, eggs, yogurt if tolerated, and lean meat are common options. Your normal diet can often resume as appetite returns.
Foods that may aggravate symptoms
Alcohol, large fatty meals, heavy spice, high caffeine intake, and very sugary foods or drinks can worsen symptoms for some people. Temporary lactose intolerance can occur after gastroenteritis.
Children and infants
Children should generally continue age-appropriate food, and infants should continue breast milk or formula unless a clinician advises otherwise. Hydration and warning signs are more important than forcing a restrictive menu.
After symptoms improve
Expand food variety gradually. If one food repeatedly triggers diarrhea, note the pattern and discuss it with a clinician if the problem continues.
Common questions
Is the BRAT diet necessary?
No. Those foods may be tolerated, but an overly restrictive diet can lack protein, fat, and other nutrients.
Should I avoid dairy?
Only if it worsens symptoms. Temporary lactose intolerance can happen after an intestinal infection.
Are probiotics required?
No. Evidence varies by strain and situation; they are not a substitute for hydration or medical care.
