Bowel issues should be a subject to itself! So many answers! First, she should be discussing with oncologist. Drugs like odansetron and olanzepine are prescribed for us with the “potential” for constipation. It’s much more than the potential!!!
I will not take them after one horrible experience.
Some of the many things I was advised:
1) drink a cup of warm prune juice
2) add Benefiber to diet
3) take gentle acting Senna pill
4) all else fails-suppository

Help your friend speak to their nurse about some of these options and more. I’m sure many more can chime in!
