The Myths

Myth #1: My child is only affecting their muscle and body fat by not eating.

  • Their stomach and intestines may work slower leading to pain, constipation or bloating.

  • Your child may develop anemia, poor immune function and bleeding disorders. Children who haven’t  started puberty may have delayed puberty or slow growth.

Myth #2: Eating disorders are a choice to not eat enough food.
TRUTH: Eating disorders are complex medical and mental illnesses that patients don’t choose.

Myth #3: I caused my child’s eating disorder.
TRUTH: Eating disorder researchers and clinical experts believe that eating disorders are caused by both environmental and genetic factors. People’s genes put them at risk to develop an eating disorder,and then different social pressures may cause them to develop the disorder.

Your child will need help managing their emotions and thoughts around eating adequate amounts of food. This is why having a mental health provider such as a counselor or a therapist is so important in the treatment of eating disorders.

Myth #9: My child will never recover from an eating disorder.
