Inflammatory Bowel Disease Center

Welcome to the Dartmouth-Hitchcock IBD Center

Crohn’s disease and ulcerative colitis are chronic inflammatory bowel diseases that affect over one million people in the United States. The Dartmouth-Hitchcock Inflammatory Bowel Disease Center is the only center in Northern New England exclusively dedicated to the care of patients with Crohn’s disease, ulcerative colitis and other inflammatory bowel diseases. At our Center, we follow over 2,000 patients with IBD.


Our providers have extensive experience using both standard and cutting edge therapies. We aim to fine-tune medical therapies to get the most benefit possible to improve the quality of life of our patients. Our surgeons are skilled in the advanced techniques required to care specifically for patients with IBD.

Quality of Care

In collaboration with the Crohn’s and Colitis Foundation of America (CCFA), the Dartmouth-Hitchcock IBD Center is leading a national effort to improve the quality of care delivered to all patients with IBD. By measuring what we do well and identifying where we can do better, our goal of this patient-centered program is to improve the quality of life for everyone affected by IBD.
