Shakes with added fiber 2 days post op?

I'm 2 days out from surgery and am home on protein shakes and clear liquids. One of my shakes has the same consistency as the others  but has 3 grams of fiber. Does this matter or should I avoid? I thought fiber is hard to digest...

If it's in shake form, and the shake is an approved part of your group's plan, I wouldn't worry. I drink half a Premier Protein shake a few days a week, and have since my full liquids phase (which began day 3 post op) and the fiber in the shake has never bothered me. 

Thanks!
