Anorexia nervosa (AN) is a serious life-threatening disorder that develops in adolescence. It is a long-term anorexia caused by adverse psychological factors. Early on, it is characterized by active dieting and anorexia, which leads to lack of appetite, poor nativity, endocrine metabolic disorders, and, if left untreated, can lead to death. There are indications that treatments for children and adolescents are being updated, but efficacy remains unknown. Evidence to date suggests that family-based treatment (FBT) is a very effective treatment. an important model of FBT treatment is the ability of parents to be committed to helping their children regain weight and health. What can parents do? Parents are advised to: 1. Early diagnosis and treatment is a prerequisite. Find ways to seek medical attention and focus on the influence of family factors; 2. The principles of family-based treatment (FBT) should begin with parents recognizing that the eating disorder is not their fault and that they do not have to blame themselves. It is currently believed that eating disorders are caused by multiple factors, both genetic and environmental, and it is difficult to find a definite cause in a specific child; 3. Parents should be aware that their child is no longer able to take care of himself because he has suffered from a more serious illness; 4. Parents have the responsibility to supervise their children’s eating and behavior, and they should instruct their children in proper diet and exercise to ensure weight regain. Parents should take a firm stance and insist that their child consumes adequate nutrition, adding nutrition to their child will be more difficult as their child may become angry and defiant. Both parents may encounter this situation and they need to work together; 5. Parents should have a higher level of tact to get their child to actively commit to their increased nutrition; 6. Parents can read books about anorexia nervosa to increase their experience and skills in treating the condition; 7. Parents can utilize the internet and need to look for knowledge and help; 8. Parents need to build a rapport with their child; 9. Initially the Treatment may be difficult because in most cases the child is reluctant to go to the doctor and often does not recognize that his eating habits are abnormal. So it is not necessary to obtain their consent at the beginning, because parents have the right to exert influence within the limits of their authorization by making the child bear the consequences of bad behavior (e.g. withdrawal of activities of interest) by making a good agreement before the beginning of the treatment, which will influence the choices of their child. Rewarding benign behavior and punishing undesirable behavior can be beneficial in correcting a child’s eating abnormality; 10. Make it clear to the child that restoration of good health and weight regain is non-negotiable; 11. Help the child to understand that improving the way they eat is necessary and raise their level of awareness. This makes them more likely to cooperate. Doctors can suggest changes to parents, such as parents or siblings doing fun playful activities with them after eating to help the child deflect the feeling that they are obese.
