Sara Lewin

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.
