Childhood obesity can have a harmful effect on the body in a variety of ways. Obese children are more likely to have:
High blood pressure and high cholesterol, which are risk factors for cardiovascular disease (CVD). In one study, 70% of obese children had at least one CVD risk factor, and 39% had two or more.
Increased risk of impaired glucose tolerance, insulin resistance and type 2 diabetes.
Breathing problems, such as sleep apnea, and asthma.
Joint problems and musculoskeletal discomfort.
Fatty liver disease, gallstones, and gastro-esophageal reflux (i.e., heartburn).
Obese children and adolescents have a greater risk of social and psychological problems, such as discrimination and poor self-esteem, which can continue into adulthood.
