What does it mean when you have the urge to have bowel movements but can't go?

Stool urgency: This is a common complaint but the differential diagnosis is quite broad and evaluation is key to distinguishing a functional process versus an inflammatory one (e.g. Crohn's), malabsorption (e.g. celiac sprue), maldigestion, infection, functional issue (like rectal dyssynergia, pelvic floor dysfunction). Time to discuss this condition with your physician.
