Have you considered or tried an old fashioned water enema instead of the suppositories? I would suggest a warm 3 pint soap or salt solution enema as an alternative.

I'm wondering if the polyps in your gallbladder are restricting bile flow. Bile is the main way that you digest your food in the intestinal tract, restricted file flow could account for every one of the symptoms you described.

Have you tried liver flushing?

I have had a number of the problems you described. It turned out that I have 2 kinds of gluten sensitivity - Celiac Sprue and non-celiac sprue (one cause of Leaky Gut Syndrome). The Tests for Celiac Disease do not show the Leaky Gut problem, I found that I was at risk for it only because I had the genetic marker (DNA) tests done.

I tried to use various fibers for years and even if I could tolerate them at first eventually they were too upsetting to use. In addition to being gluten free I been helped by a program to improve intestinal and body health (See the Liver Flush Forum ) and following the Specific Carbohydrate Diet (website online).

It is possible that the polyps could be parasites since no biopsy was done. Flatworms know as Flukes are common in the bile system and can clog it up. I have used many herbal parasite herbs to get rid of these invaders. If you have 'liver spots' or 'age spots', small to fairly large raised brown areas on your skin it is likely these are 'fluke spots' and are an indication tho not proof that you are carrying these parasites. See the CZ parasite Support Forum for herbal remedies.

Hope this helps.
