Hypos (Low Blood sugars) happen to T2 too. Are you new to exercise?

It's not unusual to have low BS after excercise or doing strenuous work. I have them some time but don't go as low as 54. Already when the BS hits 80 I can feel a little jittery. When I went to a trip to Tokyo last year it's hard to rent a car because of the lack of parking so I mostly travelled by walking or catching the train and a few times I could feel my BS go low. Now I know why the Japanese people are trim because most of them walk and commute by train , buses or ride a bicycle.

If I were at 84 (4.67 for me) and I wanted to exercise hard or do physical work or do a gig (fiddle), I would have to boost my sugar to 144 (8) in order to prevent a hypo - I learnt this the hard way on two occasions (once I nearly blacked out and another time I was well on the way with the world spinning around me).

The reason being that for me unless I do this, there is not enough sugar in my system to replace the energy used by the muscles.

I picked up the tip from an article about an Olympic rower who is type 2 (he boosts even higher before an event) and another article about a canoeist who spent 10 minutes going round in a small circle until she got it together enough to take some sugar.

The metformin inhibits your liver from releasing stored glucose while the glyburide makes you pancrease produce more insulin. Talk to your doctor, it maybe time to change your meds.

Im a T1 and do have to do this, too.

That reminds me. When I know I am going be working physically as well as boosting my sugar beforehand, I don't take my glitazone (which does the same job as the glyburide). I restart the glitazone after I have finished working and when testing shows that my sugar levels have stabilised again, which is usually a couple of hours later.

Also, I snack every two hours whilst working and if I need to work very intensely using a lot of power, I take one dextrose tablet every hour.

Starting at a level of 8 (144), this will with luck, keep me at about 6 (108) for the duration.
