Bile salts are released into your stools by your liver, giving the stools a brown color. If your liver is not producing enough bile, or if the flow of the bile is blocked and not draining from your liver, your stools will be pale or clay-colored...since hida and biopsy negative...I would suggest you to consult your surgeon and get examined as early as possible they will help by treating your condition based on few other lab investigations reports...Regards.
