Eating disorders cross and blur the distinction between problems that are mental and those that have a physical basis. There is obviously some association both within families as well as with other personality and character traits and behaviors and the various eating disorders, but it is not that simple. If someone you love has lost significant amounts of weight quickly and you are concerned about their health or their fixation on their weight, it is appropriate to discuss your concerns with them. Obviously, this is a tricky situation, as it people's weight is a very personal topic. It is also important to encourage healthy behaviors, and weight loss
can be healthy for many of us on the heavy side of the spectrum. If you are concerned, a potential place to start would be to address the issue with some general questions. As some people want to talk about it and others will quickly become defensive, it may be necessary to speak with a closer family member or a guardian, who may be able to encourage the person to seek help from a physician sooner. Please use caution as you broach the subject, but it is appropriate to be concerned.
