Obesity means having too much body fat. It is different from being overweight, which means weighing too much. Both terms mean that a person's weight is greater than what is considered healthy for his or her height. Children grow at different rates, so it isn't always easy to know when a child is obese or overweight. Ask your doctor to measure your child's height and weight to determine if he or she is in a healthy range.
Obesity is considered a long-term complex disease. Many factors are involved in determining why some people are heavier than others and how much risk they have for developing other medical problems.
