I have worked with children on both ends of this spectrum. Ones who are overweight and ones who are underweight. There are many reasons why children are either of these things. Some of them are physical and some are emotional. The one realistic thing is that even if it starts out as physical, if you bring negative attention to it, it will become emotional. It will become what the child tells themselves. Some children who are being molested will become overweight or underweight to try to make themselves unattractive. Some become overweight or underweight because that is the only thing they have control over. This can become an addiction for people who suffer from an eating disorder. If it is a control issue, it is because they feel their life is out of control and they need to feel like they can control something to make themselves feel secure. Feeling your life is out of control, as a child, usually means that the people who are supposed to be in control, parents, are out of control. The situation then makes the child feel insecure, unsafe in their environment and so they have to control something in order to feel safe and in control. What they put into their bodes is often the only thing that they feel they can control. Sometimes it is controlling when it comes out of their bodies as well. Either by vomiting or by defecation. Withholding their bowels is a way to feel in control of their environment as well. Trying to control what goes in or out of their bodies is often the only thing in control in their lives, or so they feel.
Stopping this is done the same way any other behavior is changed unless it has become an addiction. Then a rehab is in order. There are several across the country and they are very good at changing this behavior. These video’s will help you to relax and get rid of those things standing in the way of your making better choices for yourself. Link to the relaxation and guided imagery video’s. Enjoy!
