Me too!
After the birth of my last baby, I couldn't walk for 5 minutes without needing to explode. And explode I did. Took babe into all kinds of loos in the buggy and in the sling. Just horrible. I thought it was due to my gut being moved about during the cesarean birth. I had adhesions around the bowel which put it into spasm.
Was constantly knackered and reluctant to go anywhere.
Have always had a nervous tummy- just before going on stage / giving talks I would have explosive diarrhoea, so an overactive adrenal response. And just before and during the first days of my period, would explode for a few days as well.
Got a bad tummy big on hols and shat constantly for two weeks. Couldn't sight see, just had to stay in the hotel room, or venture very gingerly to the terrace. Had to put nappy cream on my bum it was so raw, even with a bidet. Came home and took grapefruit seed extract and ponstan.
Had antibiotics for about a year for a persistant infection and back to square one, exploding and swelled up with gas.
Until my GP recommended the FODMAP diet, which after a few weeks did the trick, and for the first time in five years I had a normal poo. No exploding and no cramps. My god just wonderful. A normal one, like before, not runny, scrapy, sore, explosive, gassy, stinky or in tough little bits and then exploding.
I'm fine now, with no IBS at all. I no longer have to carry all the stuff I used to, and can pop out and run around with the kids, without clenching, having to stop walking suddenly wondering if I needed new clothes, or the really awful sudden loo trips.
Maybe try the FODMAP.? It's not a nice diet, no healthy things, but when you're no longer offered a seat on the bus, (if you've been brave enough, or have enough energy to get one), it's doable, and the FODMAP doesn't last forever.
I didn't have any problems when on hormonal contraception, and now am on HRT, still no problems.
It's so nice to be able to swim again without the fear.
