What BMI actually tells you

BMI is a screening ratio of weight to height — useful as a population-level signal, blunt as a personal one. It can't see muscle, frame, or metabolic health. Clinicians use it as one input among many, which is exactly how you should read your number.

When a clinician look makes sense

If your BMI sits at 27 or above, clinical weight-management guidelines may open options worth an honest conversation. A licensed clinician reviews your full picture — history, medications, goals — within 24 hours at GetSeen Health, and tells you plainly whether a program fits.

Good questions

Asked before starting

Is BMI accurate for athletes?

It overestimates for muscular builds — one more reason it's a screening signal, not a diagnosis. A clinician review weighs the full picture.

What BMI qualifies for medical weight loss?

Guidelines commonly reference 30+, or 27+ with a weight-related condition — your clinician applies them to your actual history, not just the number.
