My husband and I are very concerned about our married daughter, age 27, because we think she may be anorexic. She is 5'9" and weighs 120. At one time, about 4 years ago,she weighed 175, and 3 years ago, she was down to 135. Now it's 120, and she is very, very thin. She loves to cook for her husband, but is a "Sugar Buster" dieter, supposedly, and does not eat what she cooks. The women on his side of the family are tall, slim and fit. Our daughter and her husband are both very intelligent---no lack of medical knowledge, but strong denial. She has a very strong will, and though he is a strong guy, she has shown herself capable of manipulation and ---just say it---lying. We do not know what is the truth anymore. They live across the country, and we visit several times a year, back and forth. We are thinking an intervention may be needed but don't know where to begin. They are very private, of course, but we are honestly afraid for her life. I've kept this brief---but where and when and how should we become involved??? Thank you so much.
