Poop might not be dinner table talk—but it’s one of your body’s most honest health indicators. Whether your stool is hard, soft, or runny, its shape, texture, and frequency can provide insight into your digestion, hydration, and even underlying medical conditions.
This guide breaks down the Bristol Stool Chart and explains what each type means—and when it’s time to consult a BASS Medical Group provider.
What Is the Bristol Stool Chart?
Developed by researchers at the University of Bristol, this chart categorizes stool into seven types based on appearance and consistency. It's used by medical professionals worldwide to help assess bowel health.

Bristol Stool Types and What They Mean
Pro Tip: Type 3 and 4 are considered “ideal.”
Why Does My Stool Look Like That? Common Causes
- Hard, Lumpy Stool (Type 1–2)
May be caused by dehydration, low fiber intake, or medication side effects. - Loose or Watery Stool (Type 6–7)
Often caused by infections, food intolerance, stress, or digestive disorders like IBS. - Floating Stool
Could indicate fat malabsorption or pancreatic conditions. - Pale or Yellow Stool
May suggest liver or gallbladder issues.
When Should You See a Doctor?
You should schedule an appointment if you notice:
- Blood in stool (bright red or black)
- Persistent constipation or diarrhea
- Unexplained weight loss
- Changes in bowel habits lasting more than 2 weeks
- Yellow or greasy stool
