How the anorexic BMI screening works

This calculator uses the standard BMI formula and compares it with a 17.5 threshold. That cutoff is commonly referenced in clinical screening for anorexia nervosa, but it does not confirm a diagnosis. A full assessment considers eating behaviors, medical history, lab values, and mental health context.

Why the 17.5 number matters

  • It reflects a BMI level often cited in diagnostic criteria and screening tools, including summaries on Calculator.net.
  • Screening thresholds are designed to prompt follow-up, not replace a clinician's evaluation.
  • BMI alone cannot capture nutrition status, body composition, or individual health needs.

Use this result with care

If your BMI is below 17.5, or if you feel worried about your eating patterns or weight changes, please seek professional support. Early guidance can be protective, and you deserve care that considers the whole picture.
