Obesity is a common health condition that affects people of all ages worldwide. It happens when the body stores too much fat, which can harm overall health. Many factors—such as diet, lifestyle, genetics, and environment—play a role in weight gain. Understanding obesity is important because it increases the risk of serious diseases like diabetes and heart problems. The good news is that small, consistent lifestyle changes can help manage weight and improve health. This article explains obesity in simple terms, including its causes, symptoms, and practical ways to prevent and manage it safely.
What is Obesity?
Obesity is a condition where a person has excessive body fat that may harm their health. It is often measured using Body Mass Index (BMI), which compares weight to height.
