Polyps in the gallbladder occur in response to severe bile duct congestion in the liver. This also causes a fatty liver, as you can read up in The Amazing Liver Cleanse(www.1stbooks.com). Your digestive problems are a direct result of bile duct congestion. Removing the gallbladder is very risky, especially if there is a fatty liver. And, of course, it is not a cure, but a harbinger of new and more serious health problems than you already have. It is better to clean out the bile ducts through a series of liver cleanses (see above book), which will allow the liver to remove the fatty deposits and the gallbladder to repair itself and clear the polyp.
HRT products and the contraceptive pill are among the leading causes of stone formation in the liver. They have contributed to innumerable cases of chronic disease. Eating dead flesh is another major causes of gallstones. It thickens the blood veseel walls and forces the liver to produce more cholesterol (the extra amounts turn into stones). In addition, they cause lymphatic congestion, leading to weight gain. For eating a balanced diet accordig to your bodytype, please refer to The Key to Health and Rejuvenation). To help clear the polyp directly, which is only a symptom and not the problem here, I suggest you take "The Indian Herb" from lifelinewater.com.
