Hi everyone, I'm going through a tough time at the moment and hoping some of you could help. I was diagnosed with IBS a year ago, went to my GP with typical IBS symptoms, carried out blood tests, stool tests etc- all came back normal so IBS was found to be the culprit. Around 4 months ago I noticed some red flag symptoms (persistent diarrhoea/mushy stools with a lot of blood/mucus, weight loss- roughly half a stone although I'm still losing, lack of appetite, severe debilitating abdominal pain, neausea, waking at night in pain, extreme tiredness, joint pains), so I went back to my GP who suspected IBD. They ordered 3 stool samples and wanted to check my calprotectin levels, which turns out they couldn't do as a specialist only could ask for calprotectin test apparently. All my inflammatory markers on blood tests came back fine. I was still having symptoms so I was referred for a colonoscopy and had it done yesterday- everything looked normal on my colon, and bowel, no signs of inflammation. Dr did take some biopsies though due to the bloody diarrhoea. Although I am relieved there is nothing seriously wrong I am just not convinced this is down to just IBS. Background I'm 23 btw, take mebeverine 3 times daily (was on buscopan but changed to mebeverine as buscopan not helping anymore). Can anyone shed some light on this possibly? Thanks.
