Ooh, lots of questions!
Gallbladder was removed due to it perforating. The result is that since its removal, I now have developed IBS.
It gets much worse when I reduce carbs (pasta, bread, potatoes) and increase my intake of fruit and vegetables.
My thyroid function is fine (or within "normal" range), it's being checked reasonably regularly as due to also having non-anaemic iron deficiency. Probably related to the not eating masses of green leafy vegetables as it causes my IBS to flare up. GP is investigating this and as I can't tolerate iron supplements, we're looking at alternatives.
Carbs are mainly... bran cereal in the morning (IBS related), sandwich or pasta Boots meal deal at lunch. Dinner is potatoes, rice, pasta as part of the main meal although once (maybe twice) per week it's probably carb based - something like lasagna, macaroni cheese, pasta bake. Usually on days I work late so time is short and I can pre-prepare.
Working on potion size (reducing slowly so I don't then get empty and do a panic overeat).
Hope that all makes sense!
