I was told that pouches stretch and can also shrink and that the fact that I was intubating too often (not allowing my pouch to fill to capacity) was causing it to shrink. When Dr C went in to fix it in 2007 it had shrunk to just under 2 pints when it was normally a quart or more when I was doing well. It happened often during the period when I had a 'broken' valve and couldn't allow my pouch to fill.
There is definitely some level of elasticity to our guts...I am just not sure to what extent they stretch and stay distended or can shrink back.
I wonder if it is like skin? It stretches and shrinks back but not always or totally and after a while the fibers can break and never come back.
It is an interesting question and it is probably different for each or us depending on our collagene level or hormones or age.
Anybody out there with the answers?
