I Had Gastric Bypass Surgery Rny and I'm having constipation problems my surgeon told me I could use stool softener I don't know witch one is good?

DSS: A commonly used stool softener is docussate sodium, or DSS (brand name Colace). Its a gel- capsule, and it softens and lubricates your stools. Increasing soluble fiber and drinking plenty of fluid is an even better and more healthy way to soften your stools. Add at least 2 tablespoons of soluble fiber (Metamucil, Citrucel, etc.) to a glass of juice or on cereal each day is usually enough. ...Read more

The key is liquid intake. ...Read more
