Okay, here it is (it was Lindsey, aka Coltsfan715):
<div class="FTQUOTE"><begin quote>Also to add not only can being sick affect your blood sugar but your blood sugar CAN affect your breathing. When your blood sugar is high it sends out a distress signal to your immune system that there is an infection (hence why many people that are sick have correlating high blood sugars). Whether or not you have an infection the body's immune system is getting that signal and the immune system starts to respond - hence attacked parts of your body that do not need the help persay. That overactive immune system can lead to inflammation in the lungs, more constricted feelings in the chest, excess coughing and so on. </end quote></div>
And it was in <a target=_blank class=ftalternatingbarlinklarge href="http://forums.cysticfibrosis.com/messageview.cfm?catid=1149&threadid=23408&highlight_key=y">this thread.</a>
And I also stumbled across this one day from <a target=_blank class=ftalternatingbarlinklarge href="http://cystic-l.org/handbook/html/complications_of_cf.htm#Diabetes">Cystic-l handbook, diabetes complications</a>:
<div class="FTQUOTE"><begin quote>One last interesting fact, that our diabetes docs let drop like it was common knowledge (which it WASN'T to any of us pulmonary people): If your blood sugars go over 200 (see Measurement of Blood Sugar below), your white blood cells go on holiday. CF bacteria grow really well in a high-sugar atmosphere, and then the WBCs shut down "your body's main infection fighting mechanism , so that's why PWCF get so sick so fast when they get diabetes.</end quote></div>
Seems kinda contradictory, unless it is that higher blood sugars (over 140 and under 200) can cause inflamation, and over 200 are bad for encouraging bacteria growth (???).
