The Bristol Stool Chart turns awkward bathroom descriptions into numbers clinicians understand. For IBD, types 6 to 7 often track flares, while type 1 to 2 may appear with pain meds, dehydration, or distal disease patterns.

Quick tour of types 1 to 7

Type 1 is hard lumps; type 4 is smooth sausage-like; type 7 is entirely liquid.

• Types 1 to 2: constipation range
• Types 3 to 4: often goals in quiet disease for many people
• Types 5 to 7: looser to liquid, common in flares or infections
• Blood, mucus, urgency, and night stools add context beyond Bristol alone
• Use our interactive checker in Tools Lab to practice logging

How to use it well

• Log the most representative stool of the day, not every variation
• Add urgency score and night waking
• Bring a 7-day Bristol log to infusions or clinic
• Try the Bristol and flare checker

Bristol does not replace calprotectin, endoscopy, or exam findings.

When to seek care promptly

• Sudden shift to type 7 with dehydration
• Bloody liquid stools with dizziness
• No stool plus severe bloating (possible obstruction pattern)

This page cannot diagnose you. Severe bleeding, black tarry stools, fainting, fever with rapid decline, or inability to keep fluids down need urgent evaluation. See when to go to the ER and flare help.

Common myths

• Only type 4 means remission. Remission is clinical and endoscopic; stool form helps but is not the whole story.
• You must photograph every stool. Numbers and notes are enough for most visits.
• Bristol diagnoses Crohn's. It is a communication tool.

Questions for your gastroenterologist

• What Bristol range should I aim for on my therapy?
• How do we combine Bristol with calprotectin?
• Should I log separately during steroid tapers?
