Questions about Vodka and Exersise.

1, The liver dumps sugar into the blood when excercising, T2s can't always handle this and BGs go up.
Non T2s use the sugar as energy so no rise in BGs.

2, See above.

3, Alcohol keeps the liver busy dealing with it so that the liver doesn't have time to put sugar into the blood, when the liver has dealt with the alcohol a T2s BGs will often rise as the liver over compensates.

4, Alcohol simply keeps the liver busy as above.

Topics I've been interested in!
The exercise - to start with, your blood sugars go down as you use glucose in the blood. But, with lots of vigorous effort, the liver starts to dump glycogen out to replace the glucose to give you the energy you need so your sugar rises. However, the benefit of the exercise probably outweighs the temporary rise in sugar level.
Alcohol - my favourite subject! I kept a graph of all readings after meals when I had alcohol before compared to when I didn't. The post prandial readings were ALWAYS lower after alcohol. Does it make you pay after? I kept a further graph of fasting sugars when I'd drunk alcohol the day before compared to when I didn't, again ALWAYS lower when I'd had a drink the day before, UNLESS I got carried away, like on holidays, for an extended period after which my fasting sugars rose for a few days.
Basically, alcohol is seen as a toxin by the liver and is "Prioritised" for treatment. It interferes with the ability of the liver to produce sugar after eating carbohydrates because the liver is sorting the alcohol out. It also results in reduced sugar levels when you're not eating, to a degree where you can go dangerously low if you're on certain meds (like insulin obviously). I'm on diet only fortunately, so I just seem to benefit from a nice bottle of Rioja! I'll probably die of cirrhosis before the diabetes gets me!
