Why is my poop sticky and smelly?

Published in Digestive Health 3 mins read

Sticky and smelly poop can result from a combination of factors, often related to your diet and digestive health. Here's a breakdown of potential causes:

Potential Causes of Sticky and Smelly Poop

The stickiness and smell are often related to what your body is (or isn't) absorbing correctly. According to a summary from 03-Sept-2024, sticky poops can be caused by excessive fat in your stool (steatorrhea) due to diet, bile duct obstruction, and malabsorption disorders like celiac disease.

Here's a deeper dive:

  • Steatorrhea (Excess Fat):

    • Diet: A diet high in fat can sometimes overwhelm your digestive system, leading to undigested fat in your stool. This makes it sticky and often gives it a foul odor.
    • Bile Duct Obstruction: Bile helps break down fats. If your bile ducts are blocked (by gallstones, for instance), fat digestion is impaired, leading to steatorrhea.
    • Malabsorption: Conditions like celiac disease damage the small intestine, hindering its ability to absorb nutrients, including fats. This also contributes to steatorrhea.
  • Excess Mucus:

    • Food Sensitivities: Certain foods might irritate your digestive tract, causing it to produce more mucus.
    • Intestinal Infections: Infections can inflame the gut lining, increasing mucus production.
    • IBS/IBD: Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD), such as Crohn's disease and ulcerative colitis, can lead to inflammation and increased mucus.
    • Cystic Fibrosis: This genetic condition can affect mucus production in various organs, including the intestines.

What to Do

If you're experiencing sticky and smelly poop, consider the following:

  1. Dietary Review: Reflect on your recent meals. Have you consumed unusually fatty foods?

  2. Monitor Symptoms: Keep track of any other symptoms you might be experiencing, such as abdominal pain, bloating, diarrhea, or weight loss.

  3. Consult a Doctor: If the problem persists or is accompanied by other concerning symptoms, see a doctor. They can perform tests to determine the underlying cause and recommend appropriate treatment. This could include tests for:

    • Fecal Fat Test: Measures the amount of fat in your stool.
    • Blood Tests: To check for celiac disease or other malabsorption issues.
    • Stool Cultures: To identify any infections.
    • Imaging Studies: Such as ultrasounds or CT scans, to examine your bile ducts and other organs.
