Dr. Sara Lewin is a gastroenterologist who specializes in caring for patients with inflammatory bowel diseases, disorders of the small intestine and nutritional deficiencies. In addition to evaluating patients in the clinic, she performs procedures to examine the digestive tract. These include upper endoscopy, colonoscopy, capsule endoscopy – in which the patient swallows a tiny camera that transmits images – and double-balloon enteroscopy, in which the doctor can enhance viewing by inflating balloons attached to the endoscope.

Lewin's research interests include improving care for hospitalized patients with gastrointestinal illnesses and the complications of inflammatory bowel disease.

Lewin earned her medical degree at UCSF, where she then completed a residency in internal medicine, followed by fellowships in gastroenterology and inflammatory bowel disease. She belongs to the American Association for the Study of Liver Diseases, American Gastroenterological Association, American College of Gastroenterology, American Society for Gastrointestinal Endoscopy and Northern California Society for Clinical Gastroenterology.

    I can't say enough good things about my doctor and the attendant physician. Both were models of what professionals should be. They were what one hopes for in a fine physician and Doctor Lewin is a credit to her profession.

    Dr. Lewin has a very good understanding of my condition and has prescribed treatment, testing etc that's really helping address the disease. We had a good discussion on the current treatment and have a thorough follow up plan for the rest of the year.

    One of the best health care experiences with a doctor I've had in my life. Dr Lewin is a treasure and I'm delighted to have her as my doctor. I felt like all of my questions were answered with detail, care, and the best current medical knowledge. I felt completely heard and received very clear instructions for my further treatments.

    Dr. Lewin was very empathetic about my recent hospitalization, listened to my questions, provided thoughtful answers, and explained things clearly. She came up with a clear treatment plan in case I have another flare. I felt heard and supported by Dr. Lewin after a scary health crisis. She also coordinated care with my PCP while I was waiting for a follow up visit and is very responsive by Mychart.

    Dr Lewin Is fantastic at relating to me as an intelligent human being (a skill many MDs lack). I appreciate the 2 way conversation around treatment options given my more complex case. She really is a phenomenal physician and I wish more doctors could learn from her bedside manner
