What is IBD? Foundation patient basics

Selected Crohn's & Colitis Foundation educational content and Marks are used on IBDPal under license. This page summarizes Crohn's and Colitis Foundation patient education on what inflammatory bowel disease is and how to use those materials with your clinician. The Foundation does not endorse IBDPal. Education only, not medical advice.

IBD in plain language

Inflammatory bowel disease includes Crohn's disease, ulcerative colitis, and sometimes IBD-unclassified. Chronic inflammation damages the digestive tract over time without treatment.

Symptoms may include diarrhea, rectal bleeding, abdominal pain, weight loss, and fatigue. Some people have joint, skin, or eye involvement. Symptom patterns tracked over several days are more useful to your clinician than a single snapshot.

IBD differs from irritable bowel syndrome, which does not cause the same inflammatory damage on scopes. 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.

How diagnosis is made

Gastroenterologists combine history, exam, stool tests, blood work, imaging, and endoscopy with biopsy.

Disease location and behavior guide therapy. Ask your team to explain your classification in writing. Write down questions for your gastroenterologist before each visit so limited appointment time is used well.

Online education prepares questions; it does not replace testing. 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.

Using Foundation pages with IBDPal

Start with the Foundation What is IBD page as the authoritative source, then explore disease-specific pages.

Log symptoms in IBDPal between visits so patterns are visible. Medication adherence and follow-up labs are as important as diet changes for many IBD patients.

Bring unfamiliar terms to clinic for clarification. 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.

Treatment overview at patient level

Goals include healing inflammation, preventing complications, and restoring quality of life.

Medications range from anti-inflammatories to biologics. Surgery helps some patients. Tell your team about travel, work stress, sleep changes, and menstrual cycle timing when symptoms shift.

Nutrition, mental health, and vaccines are part of whole-person care. Patient education supports shared decision making; it does not replace individual medical assessment.
