Several home remedies can help ease diarrhea and speed recovery, with the most effective options being oral rehydration, probiotics, gentle foods, and avoiding certain triggers. Most cases of acute diarrhea resolve within a few days without medication, but what you eat and drink during that window makes a real difference in how quickly you bounce back.
Stay Hydrated First
Diarrhea pulls water and electrolytes out of your body fast, so replacing fluids is the single most important thing you can do at home. Water alone isn’t ideal because it doesn’t replace the sodium and potassium you’re losing. A simple oral rehydration solution works better: mix about six teaspoons of sugar and half a teaspoon of salt into a liter of clean water. Sip it steadily throughout the day rather than gulping large amounts at once.
Broth-based soups are another excellent option because they deliver both fluid and electrolytes naturally. Coconut water works too, since it contains potassium. Watch for signs that you’re falling behind on fluids: extreme thirst, dark urine, dizziness, dry mouth, or skin that stays pinched when you pull it up and release it. In infants and toddlers, warning signs include no wet diapers for three hours or more, no tears when crying, sunken eyes, or unusual drowsiness.
What to Eat (and What to Skip)
The old advice was to stick strictly to the BRAT diet: bananas, rice, applesauce, and toast. That’s fine for the first day or two, but Harvard Health notes there’s no research showing it works better than a broader bland diet. You don’t need to limit yourself to just those four foods. Brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereal are all easy on the gut and equally appropriate early on.
Once your stomach starts settling, expand to more nutritious options so your body has the fuel to recover. Cooked squash, carrots, sweet potatoes without the skin, avocado, skinless chicken or turkey, fish, and eggs are all bland enough to tolerate but provide the protein and vitamins your body needs. The goal is to return to a normal diet relatively quickly rather than starving your system of nutrients for days.
Equally important is knowing what makes diarrhea worse. Coffee stimulates your digestive tract to move faster and less efficiently, which can worsen loose stools. Alcohol irritates the stomach lining and slows your nervous system’s control over digestion, often producing watery stools. Sugar-free gum, candy, and diet drinks containing sorbitol, sucralose, or aspartame can have a laxative effect, especially when combined with other triggers. Greasy, fried, and high-fiber foods are also worth avoiding until things calm down.
Probiotics That Actually Help
Not all probiotics are created equal when it comes to diarrhea. Two strains have the strongest evidence behind them: Lactobacillus rhamnosus GG (often labeled LGG) and Saccharomyces boulardii, a beneficial yeast. Both are widely available in supplement form at pharmacies and grocery stores.
For acute infectious diarrhea (the kind you get from a stomach bug or food poisoning), both LGG and Saccharomyces boulardii shorten the duration by roughly one day. That finding comes from multiple clinical trials involving thousands of participants. For LGG, the effective dose in studies was at least 10 billion colony-forming units (CFU) per day. For Saccharomyces boulardii, studies typically used 1 to 10 billion CFU daily for 5 to 10 days.
If you’re dealing with diarrhea caused by antibiotics, probiotics are particularly useful. LGG cut the risk of antibiotic-associated diarrhea in children by 71% at doses of 10 to 20 billion CFU per day. Saccharomyces boulardii cut the risk roughly in half for both adults and children. Starting a probiotic at the same time you begin antibiotics, rather than waiting for symptoms to appear, gives you the best protection. Look for supplements that list the specific strain and CFU count on the label.
Ginger and Other Herbal Options
Ginger has a long history of use for digestive complaints, and there’s a reasonable basis for it. Ginger appears to reduce muscle spasms in the lower digestive tract, which can ease cramping and slow the urgency to go. It also influences chemical signals in the gut that are linked to nausea and gastrointestinal distress. Fresh ginger steeped in hot water for 10 to 15 minutes makes a simple tea. You can also chew on a small piece of peeled ginger or use ginger powder.
Black tea is another traditional remedy, partly because of its tannin content. Tannins are compounds that create an astringent, slightly drying effect on tissues, which is why strong tea makes your mouth feel dry. That same property may help reduce excess fluid secretion in the gut. Steep the tea for a bit longer than usual to increase the tannin concentration, but keep in mind that black tea contains caffeine, so don’t overdo it.
Peppermint tea is another common choice for digestive discomfort. It can help relax intestinal muscles and reduce the cramping that often accompanies diarrhea, though it’s better suited to the pain side of things than stopping loose stools directly.
Zinc for Children
For children with diarrhea, zinc supplementation is a strategy backed by the World Health Organization. The recommended dose is 20 mg of zinc per day for 10 to 14 days, or 10 mg per day for infants under six months. Zinc helps restore the intestinal lining and supports immune function during a bout of diarrhea. Zinc supplements for children are available as dissolvable tablets or syrups at most pharmacies. This is particularly relevant in settings where children may have marginal zinc status to begin with, but it’s a safe and inexpensive addition to oral rehydration in any context.
How Long Diarrhea Should Last
Most acute diarrhea from a virus, food poisoning, or mild bacterial infection clears up within two to three days with home care. If it stretches beyond that, or if you notice blood or mucus in the stool, a fever above 102°F (39°C), or signs of dehydration that aren’t improving with fluids, those are signals that something more than a home remedy is needed. For young children, the threshold is lower: if a child can’t keep down enough fluids to stay hydrated, that warrants prompt attention.
