Body Mass Index – BMI

Body Mass Index (BMI) Explained

Body Mass Index (BMI) is a simple and widely used method to assess whether a person has a healthy body weight for a given height. It is calculated by dividing a person’s weight in kilograms by the square of their height in meters (kg/m²). BMI provides a reliable indicator of body fatness for most people and is used by healthcare professionals to screen for weight categories that may lead to health problems.

How BMI is Used

BMI is a valuable tool for:

  • Assessing Weight Status: It helps determine if an individual is underweight, normal weight, overweight, or obese.
  • Identifying Health Risks: Higher BMI values are associated with an increased risk of chronic diseases such as heart disease, diabetes, and certain cancers.
  • Guiding Treatment Plans: Healthcare providers use BMI to develop personalized weight management and treatment plans.

BMI by the Numbers

According to the American Heart Association, BMI categories are as follows:

  • Below 18.5: Underweight – May lead to health risks such as inhibited growth and development, fragile bones, anemia, fertility problems, and a weakened immune system.
  • 18.5 to 24.9: Normal weight – Associated with a lower risk of serious health conditions.
  • 25 to 29.9: Overweight – Increases the risk of cardiovascular disease, diabetes, and other health issues.
  • 30 or higher: Obesity – Significantly increases the risk of chronic diseases such as heart disease, stroke, type 2 diabetes, and certain types of cancer.

Why BMI is Important

Understanding your BMI is crucial for several reasons:

  • Health Indicator: It provides a quick snapshot of your health status related to weight.
