How can i help my sister with her body dysmorphic disorder?

Support: Tough but hang in there . Body dysmorphic disorder is an illness and require treatment. This is tough as you do not want your loved one to go to doctors and get unnecessary surgeries. I think that a professional will also have to be involved cannot go this alone. Needs therapy and medications possibly.

See psychiatrist: She should see a psychiatrist. Ask her if you can accompany her so you can get guidance
