Overweight children may not only have health hazards, but can also have higher risk of foot problem. Kids who carry surplus pounds may be doing unending damage to their feet. Dr. Darryl Haycock a foot and ankle surgeon in private practice in Lima, Ohio says "When there is an increased amount of weight and stress being placed on the foot, it can cause some significant changes in foot structure. Children's feet aren't fully developed until the age of 14 or 15 for girls, 15 to 17 for boys, meaning their foot bones are "easily moldable." As few as 15 to 20 extra pounds can add to flattening of the arches and inflammation of the growth plate in the heel. It's difficult to determine whether children are obese because they have foot problems in the first place, which make it painful for them to be active, or whether the obesity is causing the changes in foot structure. Children and adolescents who are overweight are more likely than their normal weight counterparts to suffer bone fractures and have joint and muscle pains, according to a study conducted at the National Institutes of Health.

Treatment of foot problems generally begins with conservative therapies such as custom-made shoe inserts, known as orthotics, and physical therapy. If such approaches don't work, surgery to correct the problem may be recommended.
