According to BMI classification, what does a BMI less than 18.5 indicate?

A BMI (Body Mass Index) less than 18.5 indicates underweight status. This classification is utilized to assess whether an individual's body weight is within a healthy range in relation to their height. The BMI scale categorizes values into specific groups:

• Underweight is defined as a BMI below 18.5.

• Normal weight ranges from 18.5 to 24.9.

• Overweight is classified as a BMI between 25 and 29.9.

• Obesity is a BMI of 30 or higher.

Individuals with a BMI below 18.5 may be at risk for nutritional deficiencies and other health issues, which is why it's considered essential to monitor and address the underlying causes of low body weight. In contrast, the other classifications are established by higher BMI thresholds associated with increased health risks. Understanding these categories helps healthcare professionals assess and manage patient health effectively.
