Belle, antibiotics usually cause diarrhea in these parts - so did Xeloda
and the pain meds - oral or iv - constipate and make existing constipation worse.
I know the ostomy is still new enough to be a factor in this. In the beginning I relied on 3x daily dulcolax but then would need immodium to balance, and it would always overcorrect. But some advice I got from my SIL (the nun-WOC nurse) was to let my diet help regulate me as much as I possibly could and try to wean off the OTC stool softeners and anti-diarrheals as much as possible.
It took some patience - a couple weeks - but now I take as little OTC stuff as I can possibly get away with, and use the foods I react to for their best qualities. I do take one stool softener (generic dulcolax) in the morning and one at night for the 1st couple days after chemo (5FU is constipating, so is Erbitux.) But I also use non-medication things - heat, abdominal massage, drinking warm broths, ice cream, molasses cookies (w/a hit of ginger, too), prune juice, coffee, fats will all loosen me up. Rice, cheese will both tighten me up. It really didn't take long to figure out what foods produced which effects and which had no effect.
Paying attention to what non-medical elements helped me regulate mean that I'm a lot less dependent on OTC stuff (and their overcorrections) for regulation. I don't eat cheese or rice the 1st 2-3 days after chemo, and I don't eat ice cream the last 2 days of my cycle. And things are mostly pretty predictablle.
Hope you're feeling better.
Be in harmony with your expectations. -
