I keep having episodes around once a week where I'll get intense stomach cramps in the middle of my abdomen (around my belly button area) when having a bowel movement, and will pass a lot of stool going from a normal consistency to diarrhoea or a mushy consistency. During this I will be drenched in sweat, ringing ears and be close to passing out. Afterwards I feel exhausted and usually need a nap, it doesn't affect my appetite but my stomach will feel a little sensitive after for a day or so. My stool always smells weird when I'm having one of these episodes, it doesn't smell like 'poo', I can't describe it but it smells kind of bitter or chemically.
I've done a food diary and can't find any patterns.
For background last year I had two of these episodes which resulted in blood in my stool, a few months apart. During both episodes I was passing blood for several days. I went to the GP and had high inflammation/calprotectin (1000+) and was referred for a colonoscopy. I had the colonoscopy earlier this year and everything was normal (including biopsies) so the gastroenterologist discharged me. I had a coeliac blood test which was negative.
I want to go back to the GP but I think they will just say it's IBS if my colonoscopy was normal? It's starting to really affect my life as I feel so scared of having one of these attacks when I'm out. I feel so vulnerable and scared when I'm having one, I honestly feel like I'm dying. The idea of having it happen when I'm out of the house makes me so anxious.
