Dr. Catania Explains Body Mass Index and What It Means


For years, doctors have used the body mass index (BMI) to determine if a patient is at a healthy weight. BMI calculation divides an adult’s weight in kilograms by their height in metres squared. As well as measuring your BMI, health care professionals may take other factors into account when assessing if you’re a healthy weight.

A normal BMI is between 18 and 25. Robert Catania, MD, FACS, FASMBS, Surgical Director of Bariatric Surgery at Southern New Hampshire Weight Management, says in the United States most adults have a BMI between 25 and 30.

Dr. Catania urges patients who are having trouble losing weight and who are having a problem with their health to reach out to his office. “There are many options available to help patients be successful,” Dr. Catania says.
