Beginning EBRT next week. Do I need to follow a low-fiber diet?

Posted by johnny8924 @johnny8924, Feb 6 11:42am

I failed my first EBRT simulation and was advised to follow a low-fiber FODMAP diet and take GAS-X when needed to "ensure" a clean rectum and to eliminate gas. I passed my second simulation yesterday. The FODMAP diet provides some benefits but also some slight constipation issues. I'm not looking forward to following this diet for 28 EBRT sessions. Any advice, suggestions, recommendations, etc are very appreciated. Thank you.

Thanks, Phil. the pharmacist and the oncologist said the foods to be avoided, and the herbal drink that I was asked to stop taking, they interact with Orgovyx -- can make the possible side effects worse. So far, I haven't experienced the SEs yet (in my 4th week with Orgovyx). My herbal drink has anti-oxidants -- protecting both the good cells and the cancerous cells. Protecting the cancer cells will make Orgovyx less effective. That's the message I got from what they were saying. I am inclined to give them the benefit of the doubt, for now.

Oh for sure - NO antioxidants! But what does that have to do with fiber? Only if the AI’s were in a high fiber drink would there be a reason to avoid it.
Once you are done with worrying about rectal gas for SBRT you can eat all the fiber you desire.

What was your brother's total dose of radiation over those 5 sessions?

I didn't see Jeff's reply to the above question specifically.
It's more likely than not, his brother's total dose was 40 Gy, same as mine (this past Apr 9-21). I read elsewhere that max is 60 Gy for a PCa treatment.

It can go higher than 60 gy for SBRT, but that's close to the max — definitely a curative rather than palliative dose.

As I mentioned elsewhere (or in this thread?), I discovered later that one of the reasons they pack the 60 gy into just 5 sessions in the U.S. is related to billing: U.S. Medicare won't pay for the 20 sessions they spread it out over in other countries
