Overview

If your BMI calculator results were higher than expected, you might be feeling a little caught off guard right now. And that’s okay. Weight gain typically occurs slowly over the course of many years. So unless you’re regularly consulting a BMI chart, surprising results are to be expected.

But knowledge is power. Now that you know which BMI range you fall into, you can make a plan of action. Keep reading to learn more about BMI for women, what it means for a woman your age, and whether your BMI qualifies you for weight loss treatment.

What is BMI?

BMI stands for Body Mass Index, a classification system that helps determine whether you’re at a healthy weight for your height. A BMI calculator is a tool healthcare providers can use to help assess your risk of weight-related health conditions like type 2 diabetes and high blood pressure.

Healthcare providers also rely on BMI results to determine whether you qualify for medical weight loss treatments.

BMI for women is calculated in the same way as it is for men. It’s simply your body weight (in kilograms) divided by your height (in meters) squared.

BMI calculators don’t incorporate factors like:

  • Age
  • Sex or gender
  • Race or ethnicity
  • Body composition

Because your BMI results don’t factor in key information like your age or medical history, providers use BMI alongside other health assessments when diagnosing obesity and recommending weight loss treatments. A qualifying BMI for weight loss injections is typically 30 or higher or 27 or higher with at least one weight-related condition.

If you're considering weight management options, using a BMI calculator or referring to a BMI chart for women can be a great first step in understanding your weight and discussing potential treatment plans with a healthcare provider.
