Jill Gaidos, MD, specializes in treating patients with inflammatory bowel disease (IBD), including ulcerative colitis and Crohn’s disease.

Dr. Gaidos says she was drawn to IBD because of its variety. “I like how I get to do procedures and see some patients maybe only once, but I also get to care for others over the span of many years,” she says. “It’s not algorithmic medicine of doing one test, then another test. You have to think about the entire patient—it’s a mix of acute and chronic cases.” 

She enjoys helping patients better understand their IBD and the medications that can be used to help treat their IBD. “My goal is to get the patient feeling as close as possible to how they felt before their IBD symptoms started so they can return to enjoying life again,” she says. “It’s really nice when you see a patient and explain everything to them and they come back and tell me they had no idea of how bad they had been feeling until they started to feel better.” 

As the director of clinical research for the Yale Inflammatory Bowel Disease Program, Dr. Gaidos helps patients understand the treatment options available as not all IBD medications work for all IBD patients. “We are learning more about what causes ulcerative colitis and Crohn’s disease. Hopefully, one day we will be able to predict which patients we can put on which drug earlier instead of having them try two or three to find out what works.”
