what is the correct level of blood sugar after working out?

Are you a diabetic? On any medications?

It's common for glucose levels to rise immediately after working out, due to the stress hormone cortisol, which blocks the action of insulin. Your levels should eventually drop, and stay lower than they would have if you hadn't worked out, for several hours after working out.

It won't affect your weight loss.

As long as you are within safe levels after working out, you don't need to worry. I don't have a rise after working out, so I have to be careful not to drop too low. It's very easy for me to dip into the 70's when exercising. I avoid this by eating something like a piece of fruit before working out, and a roll of smarties candy after working out.

If you need to lower your levels, low impact exercise such as walking usually helps to lower levels without being stressful enough to trigger a cortisol reaction.

Exercise means using your muscles, which require energy. Some if that comes from carbohydrate, aka sugar; your blood ferries it around your body. This is perfectly normal, happens to everybody, including those who are losing weight.

I know of someone here on MFP that found when he ended his workouts on a high note (i.e. working his *kitten* off to the last minute of his workout), the blood sugar spike was much higher and lasted longer than when he did a gradual cool-down at the end of his workout. YMMV, but if the spike worries you, you might try a longer, more gradual cool-down at the end of your workout and see how that works for you.

It is called a "glucose dump" Basically, your body is doing what it is supposed to do. It takes about 15-20 minutes of activity to deplete the glucose in your bloodstream so the stored glucose is released to continue to give you energy. What is left over will get stored for future use.

I am diabetic so I was worried the first time I tested right after a workout and had a number around 140. I asked my doctor (a Certified Diabetic Educator) and she said to not worry about it. Having glucose in your blood is not an issue as long as it goes down. Just like eating a meal, the number should be back close to normal about 2 hours after the end of the workout.

Are you seeing a diabetic specialist or endocrinologist? Ask what numbers you should watch out for. My Dr. told me to treat a workout like eating a meal as far as what numbers I should look for.

Thank you for this.

When I was first diagnosed with diabetes I tried working out when I had high blood sugar after a meal once, because I heard diet and exercise was a good way to bring my sugars down. I obviously wasn't dealing with the diet well, but at least I could exercise!

But when I checked my sugar when I got home from the gym it was even higher than when I left. I was very confused, and that made me give up on exercise for the time being. I thought I was atypical and that exercise would do more harm than good for me. (Obviously I gave up too quickly, I wasn't really ready to commit to exercise and looking for an excuse to quit)

I never thought to ask my doctor about it, or check my sugars again two hours after exercise. It's a good thing I'm pretty, because I'm not that bright.

Now that I know this I can do some testing with my meter (I only have like 500 strips to use up... ) and see how the numbers really fall.

I've done some experimental testing just to see what happens. One day I tested every hour for the fun of it. It was interesting to see the rise and fall, even when I did nothing. My numbers rose after eating, then fell, then rose again even though I ate nothing and did not work out. Obviously, this was my body releasing glucose because it hadn't been fed and needed energy. All of this just means that one single test (or one high number) means nothing in the overall scheme of things. Consistently high numbers or a high average does.

@YepltsKriss,
I'm eating 1500 to 1800 a day so my intake is not the issue and I work out 4 to 5 times a week. I asked this,question to educate myself from others. I am trying to figuer out what combination of food and exercise will help me lose wieght but keep my blood sugar normal. I'm know what foods will give me high blood sugar but was told working out will too and it was not good. so I'm confused but still working out

Who told you that? What is your a1c? Like I told @jesslla , the important thing for diabetics like me is averages, not an individual BG number. Post-workout higher numbers are NOT going to affect your weight loss. If they did, I wouldn't be here 82 lb. lighter than when I first started.

That sounds like an interesting idea. I have plenty of strips, like I said, so I think I'll do that for a couple days and see what comes of it. My app I track my sugars in will even average them out for me, which will be interesting too.

My last A1C was 5.9, which was good, but knowing what my day looks like would be neat to know too.

My A1C is usually between 5.0 and 5.4 (have another due in a couple of weeks) so I don't worry about an individual high number. Living with T2Dm is all about living with averages. I am a bit of a data geek so I find it interesting to see how my numbers climb up and down over the day.
