Low Potassium Levels and Weight loss

[nh_user_1431600]

Over the last couple of years, my daughter, now 15 has lost alot of weight and most recently has experienced low potassium levels. she now takes a daily supplement twice a day. She has had numerous blood tests and examinations to try and determine why her levels keep dropping but no results as yet. She is eating more than she used to and drinks plenty but does not seem to be urinating or pooing much. As parents we are obviously concerned with her health and have seen many different specialists about the situation. Has anyone else experienced this and if so, what measures have u taken or what did the doctors say. My daughter promised that she is not vomiting so we cannot understand how her levels keep dropping as soon as she stops taking the supplement. She also sees someone from an Eating Disorder Team to talk about the food she eats
