You told me you have had recent obstructions and that you had been advised
to have another resection. Please be advised that the tissue (probably
to the previous resected intestine is involved) cannot be reversed
by the diet. The diet prevents further inflammation of tissue but
cannot reverse damage that is already there.
Therefore, before you go on the diet, you have two choices:
(1) You avoid even some of the "legal" foods that might plug
up the narrowed ileum or
(2) you have the resection and start from fresh and that way you can
eat just about all foods recommended.
I have experience with similar
situations; it is not unusual. What happens usually is that (if you
decide not to have the resection immediately) is that you will progress
but, occasionally, (not anywhere as often) will have an obstruction
if you have things like spaghetti squash, lots of raisins, grapes,
very fibrous foods like whole nuts, etc. Often, the inflammation will
the affected area and you can do very well watching some of the foods
(you will get plenty to eat) and may not need the second resection.
Others have the resection and eat carefully for about one month and
then eat all of the foods allowed. The reason for this is because:
once the affected area has undergone inflammation for extended periods,
that part of the intestine loses its
elasticity (yes, there are actually fibers in the intestinal wall that
are called elastic fibers) and is unable to "give and take" (stretch
and relax) as normal intestinal wall does. So, even on the diet, if
the area is really fibrotic, then some foods on the diet can actually
plug it up like the raisins, grapes, spaghetti squash, etc.
