This may be TMI as it is about my bowels
For context I'm 25, obese but otherwise healthy. I have always passed 'pellet' stools or pebble type 'sausages'.
On the 15 May I had a smooth 'sausage' bowel movement that was sticky and hard to 'clean up'. I'd had a stressful week and hadn't been eating much at all then on the Friday evening we had dominos with friends. After I ate it I started having upper stomach pain but no one else did. Over the next week I was passing sausage shaped stools that - to a normal person - would have been absolutely normal if not a little hard to clean up. I was going every other day/every 2 days as is normal for me.
On the weekend of the 21 May I hadn't been for a couple of days so passed a bigger stool which was fine but still 'smooth' rather than my pebbles again sticky and hard to clean up. Then 45 mins later I had to go again which was obviously much less solid but still in one sausage like piece. Before having this movement I got lower stomach pain as if I was going to have an upset tummy.
This week I've gone every other day/2 days as normal and things were beginning to improve and seem to be going, slowly, back to normal, hardly any stickiness etc. Yesterday I came home from work and went to the loo, it came out as a normal size for what I would usually say was my 'pebble sausage' but smooth, was difficult to clean though and sticky. Thought maybe it's just a buildup where I hadn't been for a couple of days and the ones I'd passed before were smaller. I must have passed that one at 5:30pm then woke up at 1am ish with upset tummy pain and had to go quickly to the toilet where I passed a loose stool but it was easy to clean! As soon as I went I started having that upset tummy pain again so took some Imodium to try and calm it down. At 1:15ish I had to go again and this time it was full on diarrhoea, but again easy to wipe.
There has been no blood that I can see and everything has been a normal shade of brown (except for the diarrhoea last night where it was a Sandy brown colour). I have had no pain except for the tummy upset incidents and before this started and I haven't been going any more than usual up until last night!
I'm terrified I have bowel cancer and this is the change in bowel habits. The only other thing I can think of is wheat sensitivity - I did cut it out for a couple of days just out of curiosity and it did seem to help slightly... I honestly am so worried. I will of course try and make a GP appointment on Monday unless you feel it should be before? But getting an appointment is a little tricky!
Any words of reassurance or any ideas from anyone would be great fully received.
