Adverse effects of childhood weight loss may include gall bladder disease, which can occur in adolescents who lose weight rapidly. Another concern is inadequate nutrient intake of essential or non-essential nutrients. Linear growth may slow during weight loss. However, impact on adult stature appears to be minimal. Loss of lean body mass may occur during weight loss. The effects of rapid weight loss (more than 1 pound per month) in children younger than 7 years are unknown and are thus not recommended.
There is a clear association between obesity and low self-esteem in adolescents. This relation brings other concerns that include the psychological or emotional harm a weight loss program may infer on a child. Eating disorders may arise, although a supportive, nonjudgmental approach to therapy and attention to the child’s emotional state minimize this risk. A child or parent’s preoccupation with the child’s weight may damage the child’s self-esteem. If weight, diet, and activity become areas of conflict, the relationship between the parent and child may deteriorate.
