ive had my gallbladder removed in 2010, and have had painful gas on both sides of my stomach and chest, several bouts of constipation, obvious diahrrea and fatigue. My PCP, just put me on cholestyramine powder. She said it binds the fats that your body cant break down, which will stop the diahrrea, constipation and gas pains. Thus making me have normal bowel movements. Is this true?
