Sara Lewin

MD

Gastroenterologist

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.

    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

    She listened to my description of my problem and ways I had compensated to take care of it. She assured me that she would have more information from an upcoming procedure and we could discuss further with the upcoming procedure.

    She is very professional and was enthusiastic to help me. I opted out at this time for the treatment she would be providing only because my condition had improved after taking Budesonide for almost three months which was ordered by my gastroenterologist. Would definitely reconnect with her if the need arises.
