ComplicationsBy Mayo Clinic staff
Childhood obesity can have complications for the physical, social and emotional well-being of your child.
- Type 2 diabetes. Type 2 diabetes in children is a chronic condition that affects the way your child's body metabolizes sugar (glucose). Type 2 diabetes is caused in part by a poor diet, and can often be reversed by eating healthier foods and exercising.
- Metabolic syndrome. Metabolic syndrome isn't a disease itself, but a cluster of conditions that can put your child at risk of developing heart disease, diabetes or other health problems. This cluster of conditions includes high blood pressure, high blood sugar, high cholesterol and excess abdominal fat.
- High cholesterol and high blood pressure. Your child can develop high blood pressure or high cholesterol if he or she eats a poor diet. These factors can contribute to the buildup of plaques in the arteries. These plaques can cause arteries to narrow and harden, which can lead to a heart attack or stroke later in life.
- Asthma and other breathing problems. The extra weight on your child's body can cause problems with the development and health of your child's lungs, leading to asthma or other breathing problems.
- Sleep disorders. Sleep apnea, a condition in which your child may snore or have abnormal breathing when he or she sleeps, can be a complication of childhood obesity. Pay attention to breathing problems your child may have while sleeping.
- Early puberty or menstruation. Being obese can create hormone imbalances for your child. These imbalances can cause puberty to start earlier than expected.
Social and emotional complications
- Low self-esteem and bullying. Children often tease or bully their overweight peers, who suffer a loss of self-esteem and an increased risk of depression as a result.
- Behavior and learning problems. Overweight children tend to have more anxiety and poorer social skills than normal-weight children have. At one extreme, these problems may lead overweight children to act out and disrupt their classrooms. At the other, they may cause overweight children to socially withdraw. Stress and anxiety also interfere with learning. School-related anxiety can create a vicious cycle in which ever-growing worry fuels ever-declining academic performance.
- Depression. Low self-esteem can create overwhelming feelings of hopelessness in some overweight children. When children lose hope that their lives will improve, they may become depressed. A depressed child may lose interest in normal activities, sleep more than usual or cry a lot. Some depressed children hide their sadness and appear emotionally flat instead. Either way, depression is as serious in children as in adults. If you think your child is depressed, talk with him or her and share your concerns with his or her doctor.
