What is Crohn's disease? Foundation basics

Selected Crohn's & Colitis Foundation educational content and Marks are used on IBDPal under license. This page bridges Crohn's and Colitis Foundation education on Crohn's disease with IBDPal tools for logging and visit preparation. The Foundation does not endorse IBDPal. Education only, not medical advice.

What Crohn's can affect

Crohn's may involve any part of the gastrointestinal tract from mouth to anus, often in patches. Deep inflammation can lead to strictures or fistulas.

Common symptoms include diarrhea, pain, fatigue, weight change, and perianal disease. Symptom patterns tracked over several days are more useful to your clinician than a single snapshot.

Extraintestinal manifestations may affect joints, skin, and eyes. Discuss how this topic applies to your current disease activity with your gastroenterologist. Logging patterns in IBDPal or a notebook helps clinicians see trends beyond a single visit. Your GI team can adjust recommendations based on labs, imaging, and symptom trends. Second opinions are reasonable when plans feel unclear or symptoms persist despite treatment. If symptoms worsen while you try these steps, contact your clinic using your flare pathway. Bring these observations to your next IBD appointment so your team can personalize advice.

Disease patterns clinicians track

Location such as ileal, colonic, or ileocolonic disease shapes monitoring.

Behavior includes inflammatory, stricturing, and penetrating phenotypes. Write down questions for your gastroenterologist before each visit so limited appointment time is used well.

Ask your GI team to explain your latest imaging and endoscopy in plain language. Bring these observations to your next IBD appointment so your team can personalize advice. Children, older adults, and post-surgical patients may need modified guidance from specialists. Patient education supports shared decision making; it does not replace individual medical assessment.

Partnering with your care team

Track stools, pain, and medications in IBDPal between visits.

Do not use education pages for emergency triage. Tell your team about travel, work stress, sleep changes, and menstrual cycle timing when symptoms shift.

Report fever, severe pain, or obstruction symptoms promptly. Patient education supports shared decision making; it does not replace individual medical assessment.
