Raye, it depends on what you mean by 'light.' If the stool color is verging on white, then no it's not. It could suggest not enough bile is being release, especially if you're experienicng constipation-like events.
If you're talking about a yellow-y color and the stools are soft/mushy, then it could be too much bile output or bile being dumped at inappropriate times.
Thank you so much for your reply. I am talking yellow stool, but at times it is almost white. I had pancreatitis prior to having my gallbladder out due to gallstones. Three weeks after my surgery I began to have the upper right quadrant pain. My doctor thinks the surgeon may have left stones in my common bile duct. I fear that I may have Sphincter of Oddi. Again, Thank you for your reply.
I falled to mention that when I had pancreatitis I experienced white stools.
You need to request further testing. You may want to consider asking about an MRCP to see if any stones or sludge can be found in ducts - can and does happen. Also get your liver and pancreatic enzyme levels checked.
