Does Fiber aid more in controlling Diarrhea or Constipation?

My hubby's blood pressure meds really destroy his digestive track. He takes Amodium-D to help with the diarrhea, but it has it's limits. The diarrhea is a consistant side-effect of all blood pressure medications, so nothing thus far is out there that he can switch to.

I'm trying to find a natural – NON CHEMICAL – way of aiding in normalizing his digestive track.

Any suggestions please & thanks!!

It does both. Try getting more soluble fiber and less insoluble fiber.
