I haven't heard or read anything about gallbladder problems re LC WOE. What I have heard plenty of is well-meaning but misinformed friends and co-workers ready to ascribe any ache or pain to the Atkins plan. Fortunately, none of them can ever site any hard data to back up their claims.

Regardless of whether your diet is causing this or not, if the pain persists or gets worse, get to a doctor. If it's nothing you'll have peace of mind and move on. If not, you can get it treated and move on.

I hope you feel better soon!
