However, when I last had a colonoscopy I was given something to clear my colon so that they could see what was going on. What they didn't tell me was that I would need to repopulate my gut to make up for all that had been lost. I had some later issues which I feel might have been made worse by this.
A probiotic to start with might help. Maybe others might have some ideas on this. You could ask the doctors when you have the colonoscopy.
You would only need to come off iron for a week at the most, it wouldn't be for ever. You might notice returning fatigue, but you can start the iron again after the procedure is over.
