I am concerned about a person I know who has undergone a profound unexplained weight loss over the past year. She is 44, 5'4", and weighs 93 lbs- she has dropped 6 sizes in a year and a half. She is NOT anorexic or bulimic - her partner and people who work with her see her eat and she does not have ambivalence or odd habits with food.
There is no drug use that I know of. She does not have health insurance- so although it is a concern- a workup would be expensive. She works full time and does not miss work. Still, it seems to me that something very serious must be wrong and that her heart might be at risk if she keeps losing weight. I am concerned, but I don't know what to do.
