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.

How CMP and BMP Blood Tests Differ and Which to Choose

Know Which Critical CMP Values Are Emergencies
Critical CMP values are the few results that signal a true emergency—mainly electrolytes and blood sugar, where potassium near 6.0 mEq/L can't wait.
Understanding Low Sodium Causes and the Signs That Matter
Low sodium is more often a water problem than a salt one. Here's what actually causes it, and why a level below 125 mEq/L can signal an emergency.
What a Low Albumin Result Means and Why It Happens
Low albumin is a clue, not a diagnosis. Because albumin has a 21-day half-life, one low reading reflects weeks — not a bad day. See what drives it.
Understanding High Potassium Causes and When to Act
High potassium on a blood test isn't always dangerous — and sometimes it isn't even real. Learn to tell a true result from a false one, and when it's urgent.
