I never had a gallbladder attack, so I don't know what that is like. My gallbladder was only functioning at 13%. It was very swollen and hard. The surgeon told my husband after the surgery that he saw scarring on my gallbladder too. If I had waited, I could have had a full blown attack. With 2 young boys here at home, I didn't want to chance it.
I don't think you can lose weight from gallbladder surgery alone. I had to change the way I ate before I had my surgery, not only because of my gallbladder, but because of heartburn and nausea. I still have heartbrun, not as bad, but I am still getting it.
If you choose to eventually eat anything you want, you won't lose weight. But if you decide to change the way you eat for your health, you can lose some weight.
Gallbladder surgery doesn't cause a huge weight loss unless you are one of those people who has trouble eating afterward.
But I know my gallbladder was shot because of all the years of eating whatever I wanted. Now, after the surgery, I am still watching what I eat, and when I get the ok from the surgeon, I will start walking again.
It might not cause weight loss on it's own, but going through gallbladder surgery was a wake up call for me. Sure, if I wanted to, I could eat whatever I wanted, but why put more undo stress on my body. I want a healthy heart too!
So, after your surgery, take it easy. I have stuck to the low-fat diet so I wouldn't be nauseous all the time. I haven't had any nausea. It has helped me, it might not help everyone.
