🧮 BMI Calculator for Seniors
Age-adjusted results with guidance specific to adults over 65 — built by a pharmacist
⚠️ Important for older adults: Standard BMI ranges were developed using younger adult populations. For adults over 65, many clinicians use a slightly higher healthy range (BMI 23–30) because modest extra weight can be protective in older age. This calculator shows both ranges.
