I have read that bile is composed primarily of water but also contains a quantity of cholesterol. After bile is utilized for digestion, the body absorbs it for recycling by the liver. If bile production is increased as a result of liver flushing, even though much of it leaves the body, I'm sure that much of it is absorbed. I'm not surprised that blood cholesterol might rise after the first few flushes. It seems logical that more and more flushes will eliminate more and more cholesterol from the liver which will eventually reverse the rise in cholesterol. It is likely a build up of cholesterol concentration in bile in the liver's ducts which started the stone formation in the first place. Among other things, drinking a lot of water will help keep bile flowing and will reduce cholesterol concentration in bile, once good flow is established by the flushes.
