My dd 23 was overweight at 5'4 and 12 stone. She decided she wanted to lose weight about four months ago which I supported. She's now told me that she now weighs only 7 and a half stone. I'm concerned that she's not weight so quickly and about how obsessed she is with what she eats. I know she's an adult but she's still only young and still my daughter. I would like her to go to the doctor but unfortunately she doesn't want to go which I respect as she's an adult but I'm so worried about her health.
