Bladder and Bowel Preparation for prostate radiation

I have multiple bowel issues - with IBS a shorthand for it, so problem is both constipation and diarrhea. I just want to control *when* so I can have it empty for treatment. Miralax (recommended by GI) has been a great help, but not sufficient, or I'm using it wrong or at the wrong time. Also, I have only been using it for a few weeks.

The Miralax will definitely help the constipation. But because it is an osmotic laxative it could cause a watery stool. IBS is a certain entity, but unfortunately, even GI doctors use it as a catch all term for unexplained digestive issues - it’s not!
I suggest the FODMAP diet - look it up. It excludes many trigger foods - certain sugars and carbs that are fermentable and produce gas, which is a big no-no if radiation is involved.
I don’t have IBS and I basically followed this diet for the 6 weeks leading up to my 25 sessions. It’s not a guarantee, but by eliminating the gassy, fermentable components of your diet you will hopefully eliminate the “triggers” causing diarrhea.
The Miralax should keep you regular but if you find it’s not enough, I also used Healthy Fiber (amazon) - a guar gum based, non-fermentable fiber additive; drink PLENTY of water with it!
Stay away from psyllium - very irritating if you have IBS. Hope this helps
