Anorexia and Siblings: What Can I Do to Help?

If your brother or sister has suffered from anorexia, you may feel at a complete loss as to how to help or support your family member through this devastating illness. Anorexia and siblings present a unique challenge.

As a sibling, you have likely seen many changes in your family member as Anorexia develops, be it subtle or drastic. Perhaps you have been in denial about the behaviors you have seen in your brother or sister.

Maybe you have felt confused about patterns you have seen your sibling develop or frustrated at the strain that has been put on your family as a result of anorexia.

A Complex Disorder with Complex Emotions

You have likely experienced a myriad of emotions as you have observed many changes in your loved one, and know that you are permitted to feel such things. Anorexia is a complex psychiatric disorder that involves an intricate web of factors, and the process of overcoming this illness will require dedication.

As a sibling, it may be helpful to learn the basics of Anorexia to have a better understanding of what your sibling may be facing.

How to Start

To start, know that the eating disorder is not anything that was “caused” by any one person or factor. You or your parents or anyone else for that matter cannot assume responsibility for causing Anorexia to develop in your sibling. Anorexia develops as a result of multiple factors, including biological predispositions.

The nature of your sibling’s genetic make-up and neurobiology had a tremendous influence on whether or not they would develop Anorexia, and these are factors that no single person has any control over.

By understanding that you cannot change the past or the fact that your sibling has developed Anorexia may help alleviate any guilt or responsibility you may be feeling. Know that you can look ahead with hope for your entire family.

What Can I Do to Help?

This might be under the guidance of a family therapist and treatment team. Collaborate with your parents or guardians to understand your role in the recovery process. Your brother or sister will need a support system at home, and being on the same page can promote consistent practices for recovery.

If your family is working with a therapist, inquire about family-based treatment, which has been an effective treatment method for anorexia.

Your Sibling Is Separate from Their Eating Disorder

Throughout this process, try to remember and focus on your sibling as a separate entity from the eating disorder. Anorexia is a vicious disease that can take over everything you once knew to be true about your sister or brother.

As recovery takes place, you will see them emerge once more, and your love and support can help them through this process.
