What you will learn
Medically reviewed by
Dr. Shanto Arian is an internal medicine physician now specializing in clinical and aesthetic dermatology, with a parallel academic focus on epidemiology and public health. He holds an MBBS, MPH, MSc (UK), MRCP (UK), MRCPI (Ireland), Diploma in Dermatology (UK), and Diploma in Aesthetic Medicine (USA). Dr. Arian trained in internal medicine, including hospital work on hematology cases such as graft-versus-host disease, before moving toward dermatology. Skin is one of the earliest places diabetes shows itself, from acanthosis nigricans and diabetic dermopathy to slow foot wound healing, and that intersection is where his clinical and Diabic-review work meet. On Diabic, Dr. Arian medically reviews content on diabetes diagnosis, complications, dermatologic manifestations, and pharmacotherapy, ensuring every claim aligns with current ADA, NICE, and peer-reviewed literature.
