Obesity Topic Guide

Obesity is a long-term health condition defined as having an excessive accumulation of body fat that poses a risk to our health. It is commonly identified in adults with a Body Mass Index (BMI) of 30 or higher, and children with a BMI at or above the 95th percentile for their sex and age.

Having too much body fat can cause inflammation and other lasting changes in the body. Obesity raises the risk of many serious health problems for both children and adults. The risk is higher with the more weight a person has and the longer they carry it for. In children and adults, obesity increases the chance of health problems, such as high blood pressure, heart disease, type 2 diabetes, liver disease, and some forms of cancer, among other health problems. Eating healthy foods, being physically active, and managing stress can help prevent obesity and support better overall health.
