Why is BMI important?

A Body Mass Index (BMI) in the Obese range can increase the probability of contracting the following chronic conditions and diseases:

  • Diabetes
  • Hypertension
  • Heart Disease
  • Stroke
  • Cancer

Insurers take BMI into consideration when deciding whether or not to offer life, TPD, trauma or income protection cover. Sometimes if an individual’s BMI is in the obese range a premium loading will be applied to reflect their increased risk profile. Those individuals who have a BMI above 40 may struggle to obtain cover.

There are an increasing number of insurers who offer premium discounts for a healthy BMI. This includes discounts at the beginning of a policy and also rewards for maintaining a healthy BMI during a policy’s term. Find out how much you can save.
