I don't know about the pumpkin but I always have a small bag and a few cans of I/D food at home just in case. Thor is a little ah "delicate" at times.
We do, too!
Once in awhile, just like all of us, or a child, the intestines just get a little bug.
Another suggestion, is a dollop of yogurt, atleast once a day.
With the surgery, pain meds, stress, injury, the healthy bacteria in the intestines is destroyed. What happens then is that the bad bacteria have an opportunistic advantage.
C dif can result, a compromised immune system, constipation, toxins are not expelled, UTI can present ...
If yogurt is not an option, you can go to Whole Foods and/or any other Natural Supplement store and purchase refrigerated acidophilous. This is in a liquid form and it is the live healthy bacteria in mammals' intestines.
Start with a 1/2 teaspoon once a day. PM with any questions. There is so much more available.
