Sameer Patel — Founder & Editor
Sameer Patel is the founder and editor of My Medicine Advisor. He is not a doctor or medical professional — before starting this site he worked in banking, and he now researches and edits health information full-time.
He started My Medicine Advisor to make clear, well-sourced health information freely available to anyone. Every article is researched from recognised authorities such as the WHO, CDC, NIH, and NICE, drafted with the help of AI tools, and edited by hand, with sources linked so readers can check them. The calculators on the site use established, published formulas, each one named so you can look it up yourself.
My Medicine Advisor is currently a one-person operation with no clinical review panel, and the site is open about that. If you're a qualified clinician or researcher interested in reviewing content, Sameer would genuinely like to hear from you via the contact page.
