Many people search for blood in the stool and miss the quieter siblings: mucus, sudden urgency, and tenesmus (the feeling you still need to go when little comes out). These symptoms are common in colitis and deserve clear language at visits.

Plain definitions

• Mucus: clear, white, or yellow jelly-like material with stool
• Urgency: little warning before a bowel movement
• Tenesmus: straining or incomplete emptying with small volume

If bleeding is also present, read blood in stool with IBD.

What to track for 48 hours

Count daytime and night trips, estimate mucus versus blood, and note whether urgency wakes you. Night symptoms often matter more to clinicians than a single daytime rush. Pair with flare first 48 hours while you message the clinic.

When to escalate care

• Heavy bleeding, dizziness, or black stools
• Fever with severe pain on immunosuppression
• Inability to keep fluids down

See when to go to the ER for red flags.

Questions for your GI team

• Does this look like active colitis or infection?
• Should we check calprotectin or stool studies first?
• What bathroom-access plan is realistic for work or school?
