BMI Categories and Ranges

Underweight: < 18.5

Your Body Mass Index(BMI) indicates that your body weight is considered lower than what is healthy for your height. Being underweight may indicate insufficient muscle mass or body fat, and it can increase the risk of nutritional deficiencies, weakened immunity, and other health issues.

Normal weight: 18.5 – 24.9

This is considered a healthy weight range for most adults. Maintaining a BMI in this range is generally associated with a lower risk of chronic diseases, balanced energy levels, and overall good health.

Overweight: 25 – 29.9

Your weight is higher than what is considered healthy for your height. Being overweight can increase the likelihood of developing conditions such as high blood pressure, type 2 diabetes, and cardiovascular disease. Lifestyle adjustments, including diet and exercise, may help reduce these risks.

Obesity I: 30 – 34.9

This is the first stage of obesity, indicating mild excess body fat. Health risks such as heart disease, high blood pressure, and metabolic disorders are higher in this category. Medical consultation may be recommended to manage weight and prevent complications.

Obesity II: 35 – 39.9

This stage represents moderate to severe obesity. Individuals in this range are at significant risk for serious health issues, including type 2 diabetes, heart disease, sleep apnea, and joint problems. A structured weight management plan with medical supervision is often advised.

Obesity III: ≥ 40

Also known as severe or morbid obesity, this category carries very high health risks. It is strongly associated with life-threatening conditions such as cardiovascular disease, stroke, diabetes, and certain cancers. Intensive medical intervention, lifestyle modification, and sometimes surgical options may be considered.
