I'm 20 years old and female. Had acute lymphoblastic leukaemia age 2-4. Yearly checks afterwards were always normal thankfully. I haven't been poorly since I was 15. 

I got a call from the drs a few weeks ago as someone in my family messaged them concerned about my weight.

I agreed to see the dr about my weight loss but that time, I didn't want to admit to myself (let alone the dr) that I've not been eating much on purpose and going on walks a lot more to lose weight even though I'm already underweight. I don't understand why I'm like this because I used to love food but I'm going to tell my dr next time about this.

I said that I have just lost my appetite and stressed (I feel guilty about lying, I know I should have just been honest). She weighed me, felt my tummy and listened to my chest and said she'll request a CT scan. She also asked me to give a stool sample and a bowel screening test. I didn't expect any of those to be abnormal.

My screening test is positive at 400 and my faecal calprotectin is slightly raised. I didn't expect those at all, especially since I didn't see blood when I did the test.

Now I've realised my weight has gone down very fast and it's probably not caused by just diet and exercise.

I'm going to have a phone appointment tomorrow to discuss test results.

Any advice?
