What is the classification associated with a Body Mass Index (BMI) below 18.5?

A Body Mass Index (BMI) below 18.5 is classified as underweight. This classification indicates that an individual's body weight is considered too low for their height, which can pose health risks such as nutritional deficiencies, weakened immune function, and osteoporosis, among others.

BMI is a widely used tool that helps assess whether an individual's body weight is within a healthy range compared to their height. The categorization of BMI into various ranges helps healthcare professionals evaluate potential health risks and provide appropriate guidance. The thresholds established by the World Health Organization categorize BMI as follows: underweight (BMI less than 18.5), normal weight (BMI between 18.5 and 24.9), overweight (BMI between 25 and 29.9), and obese (BMI 30 and above). Understanding these categories is essential for promoting a healthy lifestyle and addressing any associated health concerns.
