Definitely worth a check with your GP about the best course of action. I'm still having a lot of problems after having mine out in early March. It's nice not to have a skanky gallbladder festing inside anymore and the attacks though.
I have to be very careful with fat still and not eat too much so have been trying to have more smaller portions to keep me going through the day, a little porridge pot for breakfast at work, a banana for a snack, a plain ham sandwich for lunch and cereal/grain bar for a snack etc... I trial little bits of things with fat in to see if it's calming down but not much joy and I'm running before I even finish the meal sometimes and have had accidents.
I have been trying lots of chicken noodle simmer soups with bread to dip and wraps or the small bread (like the Warburtons toastie) sandwiches with wafer thin chicken and tomatoes and a bit of salad cream.
My main issue is very bad diarroeah (and horrible bloating and discomfort with it and air, had been burping a lot but that's calmed down a lot now). I had bile acid malabsorption before and it responded well to medication (bile acid sequestrants) but not so much anymore, it can take the edge off it but not control it.
I've mentioned it to my GP (when speaking about other stuff) but have said I'm still waiting to see for a bit in the hope it settles itself down. I had a big problem with lactose and gluten years ago (after having eating disorder issues) and had to avoid them for quite a while but managed to reintroduce them after some time so long as I don't overdo it.
