Careful, current and personal
Dr. Siddiqui believes good hormone care starts with listening. Many of her patients have been told their labs are "fine" while they still feel unwell, or have tried diet after diet without lasting results. She takes the time to find out why.
Her focus areas include medical weight loss, diabetes, thyroid disease, bone health and hormone conditions such as PCOS and low testosterone. As a board-certified obesity medicine specialist, she treats weight as the medical condition it is, using FDA-approved treatments and plain-language explanations.
She also teaches the next generation of doctors as core faculty for the internal medicine residency and site director for the endocrinology fellowship.
