Crap Story
Saturday, December 30th, 2006Well… I shall end this year with a crap story…
Many years ago, I was staying over in
Dennis’s place. He is a good friend from meds school. The next
morning, while he was busy preparing a simple breakfast, I went to
pooh in his toilet.
“CH, you very ‘kengchao’ (ie great),
can shit so early in the morning! I can’t do that… I can only shit
after eating my breakfast…”
“I never have that problem, I can
shit anytime. Well… maybe you should try sitting on the toilet
early morning before breakfast, I am sure you can do it…”
“Really cannot lah… before
breakfast, no 灵感(Ling2
Gan3, ie inspiration) to shit. Must be something to do with the
pressure in the stomach; after eating the pressure built up, then it
push the shit out the other end…”
Well… many years after graduating
from meds school, I was preparing for a talk about management of
constipation in childhood, I came a cross this article suggesting to
sit children with constipation on a potty after meal time to
encourage defecation. The physiology explanation for doing so is to
make full use of the Gastrocolic reflex.
When food enter the stomach, there is a
reflex increase in muscle contraction in the colon, this is the
gastrocolic reflex. This reflex also explained why newborn baby pooh
every time they have a breast feed. It also explained why Dennis was
able to shit after breakfast.
The moral of the story are..
-
It is never too late to learn
physiology… -
My friends who are scattered
around the world… I still think about you guys (or at least your
crap stories) even though we are not in constant contact. Thanks
guys for the card from BELFAST…
Happy New Year!
