Why Do I Keep Pooping So Often: Causes, Solutions, and When to Worry

Frequent pooping can be due to diet, fiber, caffeine, infections, or conditions like IBS. See a doctor if it persists.

Normal range

From 3 times a day to 3 times a week is normal.

Common causes

• Diet and fiber.
• Caffeine.
• Stress.
• Infections.
• IBS.
• Medications and sweeteners such as sorbitol.
• Lactose intolerance.

Other causes

IBD, celiac disease, an overactive thyroid.

See a doctor

If you have blood, weight loss, fever, night symptoms or it lasts more than 2 weeks.

What is normal

Healthy people have bowel movements anywhere from three times a day to three times a week. Frequent bowel movements are a change from your normal pattern. Pooping more than 3 times a day regularly, with loose stools, is generally classified as diarrhea.

Diet causes

• High fiber intake or sudden diet changes.
• Caffeine, alcohol and sugary drinks.
• Artificial sweeteners (sorbitol, xylitol, mannitol).
• Lactose intolerance.
• Spicy or fatty foods.
• Fluids and large meals due to the gastrocolic reflex.

Medical causes

• Irritable bowel syndrome (IBS), affecting about 10% to 15% of people worldwide.
• Infections: viral, bacterial, parasites such as Giardia.
• Inflammatory bowel disease (Crohn’s disease and ulcerative colitis).
• Celiac disease.
• Hyperthyroidism, which speeds up metabolism.
• Medications such as antibiotics, metformin, magnesium supplements and laxatives.
• Colon polyps or cancer, less commonly.
• Anxiety and stress.

Food intolerances

Fructose, lactose, gluten, and FODMAPs in some people.

What to do

• Track what you eat and your bowel movements.
• Stay hydrated.
• Try eliminating suspected foods for 2 weeks.
• Consider a low FODMAP diet under dietitian guidance.
• Consider probiotics, which have modest evidence in IBS.

See a doctor if

Frequent stools last more than 2 weeks, with blood, black stools, severe pain, weight loss, fever, night time diarrhea or signs of dehydration. People over 45 with new bowel changes should be screened for colorectal cancer.

What counts as normal

Normal bowel frequency ranges from three times a day to three times a week. Going more often than usual can result from high fiber intake, coffee, artificial sweeteners such as sorbitol, lactose intolerance, stress or infections. Irritable bowel syndrome affects about 10 to 15 percent of people, and inflammatory bowel disease, celiac disease, an overactive thyroid, and medications like metformin and magnesium can cause frequent stools.

Next steps

Keep a diary of foods and symptoms, reduce triggers and stay hydrated. See a doctor if frequent stools last more than a few weeks or come with blood, black stool, weight loss, fever, nighttime symptoms, severe pain or anemia. Doctors may order stool tests, blood tests or colonoscopy. The USPSTF recommends colorectal cancer screening for adults aged 45 to 75. Seek urgent help for signs of dehydration like dizziness or very little urine.
