I've recently had my gallbladder removed. Would Bile Salt Supplements help my digestive system?

Due to my gallbladder removal last September, I've been gaining weight and my digestive track has not been normal. I've been reading a lot of information on this subject and it was suggested that I might be lacking the sufficient amount (or low intensity) of the bile my body is accustomed to prior to my gallbladder surgery and thus bile salt supplements might be beneficial. But I haven't found any rock hard evidence to support that. Are there any risks ociated with bile salt supplements? Would it really be beneficial in this situation?
