About Dr. Ruth Weinstock, MD PhD
Updated Sep 20, 2026Dr. Ruth S. Weinstock is an endocrinologist in Syracuse, New York, who treats diabetes and metabolic conditions. She is a SUNY Distinguished Service Professor and chief of the Division of Endocrinology, Diabetes and Metabolism at SUNY Upstate Medical University, where she has been on the hospital medical staff since 1986 and division chief since 1994.
She founded and serves as medical director of the Joslin Diabetes Center at Upstate and is also medical director of Upstate's Clinical Research Unit. She directs the endocrinology fellowship program, which means she trains doctors who are specializing in this field.
Research is a large part of her work. Her Upstate profile says her focus is preventing and treating type 1 and type 2 diabetes and its complications, obesity, better delivery of diabetes care, and reducing gaps in care. She reports co-authoring more than 300 publications and working as a principal or co-investigator on more than 130 diabetes studies funded by the NIH, non-profits, and industry.
Under CMS Open Payments, she received a total of $118.67 across three records from 2021 to 2025, all from Mannkind Corporation. Payments from industry to doctors are common and legal, and this amount is very small.

- Direct checks of New York state medical board discipline records and court records were not completed during this research, so nothing has been either found or ruled out in those categories. upstate.edu

A word of caution about these numbers
A payment does not mean your doctor is compromised or acting unethically. Most of these entries are drug samples left for patients, or lunch brought in for the office staff, and the amounts are usually small. Research funding and speaking at medical meetings are also normal parts of a clinical career.
As a rough guide, a total under $15,000 a year is usually not a concern. Much larger sums, especially from one company whose product your doctor recommends to you, are worth asking about. You are allowed to ask.
