Yes, that is correct. After having bypass surgery it affects the bile acid in our bodies. I also had my gallbladder out, which is double whammy for me. I had suffered with diarrhea for years. Saw a Gastro Dr. for a year, who kept insisting it was the foods that I was eaten. She had her own agenda. I got an appointment with a Gastro Dr. at Jefferson University in Phila. Within 45 minutes, he diagnosed me, drew me a diagram of what was happening and put me on a cholesterol tablet 2xday (Im down to 1) and it was a complete game changer. I was advised to get a second opinion after my first Gastro Dr. sent me to a surgeon! He was flabbergasted that she did so. Recommend me to get a 2nd opinion, but, not with any of the other doctors in that practice, because they share info. So I hope that this helps!
