Awaiting fit test results then likely to be referred for colonoscopy. Suffering with constipation for a while and feeling like there is some kind of blockage, doctor has examined and done full bloods both were fine. Given treatment for constipation which worked but resulted in quite severe diarhea, some weight loss but this could be down to having to go to the toilet more. Trying not to google and think the worse but not great with health anxiety so it’s hard not to worry. If fit test comes back positive is there anything else it could be other than the dreaded? Late 40s and on good health normally, don’t smoke and hardly drink if it makes any difference. I know no one can diagnose but just looking for some reassurance really.
