I had my gallbladder out and it seems to have created a few problems ... a few months after, I was hospitalised with diverticulitis (which comes and goes, and nearly always results in hospital time), and a few months after that, I suddenly felt really unwell ... lots and lots of hospital tests later I still didn't have a diagnosis until one day a thought popped into my head to ask if I'd been tested for coeliac disease (I do not know why I thought that - must've been a guardian angel). Anyway, that's what it was.
Actually getting my gallbladder removal surgery in the first place was a very long and frustrating process ... I saw three surgeons, none of which felt that my condition was bad enough (it most certainly was - I was crouched over in pain, trying to wriggle it out, several times a day). Finally, my GP told me to go the ER next time it happened - which I did - and it was taken out a couple of days later.
Five years later, there are things I just cannot have anymore ... standard milk (I drink lactose free), some types of coffees, milky drinks (even if made with lactose-free milk), fatty foods ... it's a bit of a nightmare. Socially, it's better that I stay home. I still get "phantom" gallstone attacks, which feel like I'm being stabbed. They're so painful that if I'm driving, I have to pull over off the road and stop until the attack passes.
