Keeping an eye on your poop’s color, size, and consistency can give you important insights into your digestive health. The Bristol Stool Chart, a widely used tool among healthcare professionals, helps you categorize your stool and detect potential issues. Your poop can provide daily clues about your body's overall well-being.
The Bristol Stool Chart
The Bristol Stool Chart helps describe different types of stool, from hard and lumpy to watery and loose. By comparing your stool to the chart’s seven types, you can figure out what's “normal” and when it might be time to see a healthcare provider.


Stool Types on the Chart:
Hard, separate lumps (difficult to pass)
Sausage-shaped but lumpy
Sausage-shaped with cracks on the surface
Smooth, soft stool shaped like a sausage (ideal)
Soft blobs with clear-cut edges (easily passed)
Mushy with fluffy pieces and ragged edges
Watery with no solid pieces (entirely liquid)
Types 3 and 4 are considered healthy.
Types 1 and 2 might indicate constipation, while Types 5 through 7 suggest diarrhea.
Why is My Poop This Color?
Poop color can vary due to diet, medications, or health conditions. Normally, stool is brown because of bilirubin, a compound created during the breakdown of red blood cells. However, certain foods, like beets or black licorice, can alter its color.
Black stool: Could result from consuming blackberries or certain medications, but may also indicate bleeding in the gastrointestinal tract.
Red stool: Often caused by food dyes, but if it’s mixed with blood, it might signal conditions like hemorrhoids or colorectal cancer.
Pale or gray stool: This suggests a lack of bile, potentially caused by a blockage in the biliary system, which requires medical attention.
How Diet Affects Stool
What you eat directly impacts the shape, consistency, and color of your stool. A well-balanced diet with fiber and proper hydration promotes healthy bowel movements.
Fiber: Essential for bulking up stool and keeping it soft. Without enough fiber, you may experience constipation.
Water: Stool is about 70% water. Not drinking enough water can cause harder stools and lead to constipation.
Caffeine: Can act as a laxative by speeding up digestion, which may lead to looser stools.
When to See a Healthcare Professional
Certain changes in bowel habits may indicate a more serious problem. Seek medical advice if you experience:
Sudden changes in bowel habits
Frequent diarrhea or constipation
Greasy, foul-smelling stools
Red, black, or pale stools
Abdominal pain, fatigue, or weight loss accompanying stool changes
The Bottom Line
Your poop can tell you a lot about your health. The Bristol Stool Chart is a helpful tool to monitor your digestive system. Regular bowel movements with soft, easy-to-pass stool are ideal, but if you notice any concerning changes, it’s important to consult a healthcare provider.
