What is waist-to-height ratio?
Waist-to-height ratio compares your waist measurement with your height. Many health experts consider it more useful than BMI for estimating abdominal fat and obesity-related health risks.
Why abdominal fat matters
Excess fat around the waist may increase risk of:
- Type 2 diabetes
- Heart disease
- High blood pressure
- Fatty liver disease
- Metabolic syndrome
- Sleep apnea
