I had 2 pieces 2.5 cm and several smaller stones in my gallbladder. I took Gallmet-Natural for about six months before the surgery. They took out 1 and 0.5 cm stones. It was a cholesterol stone. Unfortunately no ultrasound was done before the surgery. I should have, I could feel myself getting better, but I didn't think so. I might have kept my gallbladder. I still take Gallmet to this day, it helps a lot.
