Overweight and obesity also increase the health risks for children and teens. For example, type 2 diabetes once was rare in American children, but the number of children with it today has grown rapidly. Early onset of type 2 diabetes can cause the early onset of complications such as vision loss, nerve damage, and cardiovascular disease.3 Researchers express concern that because of obesity, today's children will be the first generation that may not live as long as their parents.4
Some of the possible effects of obesity in children include:5
- High blood pressure and cholesterol
- Liver disease
- Sleep apnea and other lung-related problems
- Problems related to bone development
- Early onset of menstruation for girls
- Increased risk of cardiovascular disease in adulthood
In addition, overweight children are more likely to become overweight or obese as adults.
