Hello my name (… female) I am almost 21 years old, for the past year or so I have noticed a massive change in myself, I have went from being 12 stone down to 8 without having any change of diet or exercise and this was in the space of about 5/6 months I put it down to stress with college but I am no longer under stress. I have always had an issue with my weight so when I first started to lose it I was sort of happy but then it got worrying. I have now started noticing bruises that randomly appear all over my legs without any injury and I am constantly pale in colour. I have been tested for an iron deficiency and thyroid but they came back clear. what could this be?
