Hi My surgery is on the 24th May. I have been on optifast for 3months.I have been having 3 shakes a day and vegetables.Hasn't been easy but I am determined to get rid of a lot of fat of my liver which the doctor found when she did a gastrocopy(camera down the throat) they also said I had an enlarged spleen. I have lost 25 kilos. Has anyone else been told they have a fatty liver or enlarged spleen.
