he is talking about the canadian measure of mmol/l not our mg/dl standard in the US. normal blood sugar level in that unit of measure can be anywhere from 3.9mmol/l to 7.7 mmol/l depending on time of day, food intake, etc...
Look, get it checked by a good dr... diabetes is no joke... I have had severe panic attacks with heart rate above 150.... bp nearly 180/120 (MY normal BP is usually 104/66),... but my sugar levels were always well within norms... Stress is not likely to cause the pancreas to produce that much insulin... If that was the case then your level should have been super low when paramedics checked it before
blood sugar is metabolized by the liver, kidneys and insulin is produced by the pancreas... any of these could cause the problem
A heart rate of 125 is no biggie when youre stressed... in fact when you have a stress test done i have had heart rates up above 180. Here is a tip... dont concentrate too much on your heart rate as long as you are not having chest pains and the rhythm is steady and above 50bpm.
Good luck man! Having a health concern can trigger panic/anxiety... so if you expect it, it isnt so scary... and Panic Attacks DO NOT kill. Get some sort of benzodiazepine to help when the anxiety starts to build.
