Hi, I m a 25 year old female, weigh 53kg, 5 6 tall. I had kidney stones last year and lost a fair bit of weight, I ve since got better and put weight back on, I ve recently though, had no appetite whatsoever and have been losing weight again. I ve also been really cold , and feeling week in general. 100% not pregnant. There is no signs of another kidney stone/ water infection etc. Thanks in advance
