Hi Todd
In response to your feeding tube question. I had one for 6 months and found heavy excercise pretty uncomfortable. I didnt do any running or strenuous sweating excercise during that time- I walked alot did the eliptical on occasion when I felt up to it... there are people who have them for life who I'm sure do excercise a lot...
I had some clogging problems towards the end - flushing with warm water after feedings is important. If it gets clogged you can also flush it with a bit of fizzy water. Also I wrapped an ace bandage kind of thing around my waist and tucked it up that way so it wouldnt get hung up on my clothing and pull- which was painful and was a nuicance when I was active.
Hope that helps. Also hoping that your father in law gets through this all without toomuch discomfort!
