Ahsan Uddin, M.D.

Endocrinology deals with glands and hormones—pituitary, thyroid, pancreas included. That short list covers fronts where imbalances show up fast. Ahsan Uddin, M.D. keeps offices on the 3rd floor of 505 East 70th Street, inside Helmsley Tower, mid-block between York Avenue and the East River. Hormone swells, metabolic slowdowns, or glandular confusion aren’t waiting for tomorrow—neither does the next patient.

Call (646) 962-3442 for an opening without fanfare. Restroom nearby is handy. The building’s lobby receives steady sunlight after noon. Parking is off-avenue toward the FDR, and traffic moves reliably at midday. For the precise route, use the map and watch the last block sign.
