It may not always be possible to prevent or stop IBS diarrhea, but you have lots of ways to make bouts of diarrhea less common, head them off quickly when they do occur, and manage the accompanying symptoms. The basics of this include:
Learning which foods trigger or prevent diarrheaLearning which medications trigger diarrheaStaying hydratedCaring for irritated skin around the anus
Stop Diarrhea Through Diet
Prevent diarrhea in the first place by maintaining a healthy, well-balanced diet free of trigger foods. Trigger foods are different for everyone with IBS, but some common ones include:
AlcoholArtificial sweeteners or sugar substitutesArtificial fat (Olestra)Carbonated beveragesCoconut milkCoffee (even decaffeinated)DairyEgg yolksFried foodsOilsPoultry skin and dark meatRed meatShorteningSolid chocolate
You may also want to try a low-FODMAP diet, which restricts certain sugars that are hard for the body to digest. The American College of Gastroenterology’s 2021 IBS Guidelines recommend a limited trial of this diet.
Increasing Soluble Fiber
Adding soluble fiber to the diet may help reduce diarrhea from IBS. Some sources of soluble fiber include:
BarleyBrown riceCurrantsDried beansFigsFrench breadFresh peasMethylcellulose (Citrucel)Oat BranOatmealPastaPrunesPsyllium husks (Metamucil)RaisinsRiceSourdough breadSoy
Drugs That Can Cause Diarrhea
Some common medications that can cause diarrhea include:
Antibiotics Blood pressure medications Antacids containing magnesium
If you’re taking a new medication and experience diarrhea, ask your healthcare provider or pharmacist if the drug could be the cause.
Staying Hydrated
When you do have diarrhea, be sure to drink plenty of fluids to prevent dehydration. The fluids lost through diarrhea can dehydrate you quickly, especially if diarrhea is severe or goes on for an extended period of time.
While water is great for replacing that lost fluid, you may want to consider replacing electrolytes with:
Beef or chicken brothRehydrating drinks like Gatorade or PoweradeFruit drinksSoda pop
However, be careful with fruit drinks and soda, as some contain artificial sweeteners and caffeine that may trigger IBS.
Taking Care of Tender Skin
Irritation in and around the anal area can be common with severe or prolonged bouts of diarrhea. This can often occur as a result of wiping frequently as well as from the bile that’s being passed with diarrhea.
Keep the area clean using water and personal care wipes instead of toilet paper. A spray nozzle on the shower is helpful for washing thoroughly at home. Be sure the water isn’t too hot, though, or it could irritate things more.
When away from home, keep travel-sized wipes in your purse, pocket, or car. Or, pack some regular wipes from home in a plastic baggie with a secure closure.
A barrier cream can help soothe the skin and protect it from further diarrhea damage. Look for:
Diaper rash creams with zinc oxidePetroleum jellyVitamin A or vitamin D creams
A Word From Verywell
Having frequent diarrhea is not only painful and inconvenient, it can also be embarrassing and make you afraid of going out. When you take steps to prevent it, though, and you’re prepared for when it does hit, you’ll feel more confident and able to do the things you enjoy. Working with your healthcare provider and sticking to your treatment and management strategies are all part of that.
