yesterday I started a walking program (which is a huge thing for me). Anyhow, I walked yesterday and again today. This morning, I got up, checked my BS and it was high (181). I went on my walk (30 minutes/1.5 miles) and when I got back home, checked my BS and it was down to 141!

Is it normal for it to drop like that? Or was part of it the passage of time (about an hour between the levels being taken)?

My numbers only changed by 2 today but we walked faster. So, I think what Betty and Gabby stated is very true.

I really have to keep testing to see what is going to happen.

What a great question. And what great answers.
I have been very limited on exercise so far this year. Drs. orders of keeping legs elevated most of the time. Now in 2 weeks I'll have 2 weeks I can walk as much as possible. Then major surgery and gradual walking. So when I'm finally back to being able to exercise, I wont be as confused if my numbers seem crazy.
Diabetes: It's a whole lot of new stuff to learn. It affects so many things I would never have thought about.
Again thanks to all of you for the education!

About a month ago I over did it at Moe's one night when I was starving. We went to the mall and a movie afterwards and I checked my BG in the middle of the movie to see how it did and my BG was 248, an hour later when we got home I checked and it was still 179 so I took off and ran around the block then waited 15 mins and checked again and it was 123. That sold me on exercise helping and I have been working out regularly ever since. My numbers are so much better now and I feel so much better, I think the exercise is a bigger help than the Metformin which I hope to drop or cut back anyway soon if my Dr. okays it at the end of the month when I go back for my 3 month check. I would like to try to control this with diet and exercise alone if I can.

Best to you in this goal! I've been walking for years and the doc three weeks ago told me I had to do more then just walk. Joined a gym, have been going faithfully four times a week for an hour a day. All I have seen so far is that I've gained 8 pounds. I'm eating right, just won't lose. Currently the heaviest I've ever been 275! Can't run or jog because of head injury, and walking is very hard cause of sciattic pain. Feel better when I go, but I'll quite if I keep gaining.

Just be careful… your blood sugar will vary, sometimes changing by 10-15 points, just based on normal metabolism (stress, temperature measurement, etc). Generally, low intensity exercise will decrease blood sugar. Higher intensity exercise (which sometimes can even be walking for some individuals who are deconditioned) can have a tendancy to increase blood sugar. During strenuous exercise your muscles need more glucose so they send a signal for more energy which comes from the blood glucose or stored glycogen in your liver. As your body responds by releasing more glucose and without sufficient insulin, very hard exercise and sometimes even novel exercise will cause a rise in blood glucose levels.

As diabetics test before and if your blood sugar is between 100-250 it is safe to exercise. If it is less than 100, eat 15 grams of carbohydrate, and recheck your blood sugar in 15 minutes. If your blood sugar is 250+ you need to delay exercise until it is below 250.

I didn't know that. Thanks for telling me.

I have to thank Gabby for making me aware of it too. I was experiencing rises after I had always experienced drops. I didn't realize it was due to my stepping up my workouts making them more intense.

Yes, your results are typical and normal.
Exercise helps the body utilize insulin more efficiently, allow for your cells to absorb the glucose, thereby lowering your blood glucose level.
That's one of the reasons that doctors recommend exercise and physical activity among pre diabetes and diabetes patients.

So, that is also why there can be concerns about low blood sugar after exercise?

MAYS 2010-07-06 12:13:05 -0500 Report

That is not much of a factor in type 2 diabetics as it is in type 1 diabetics.
As a type 2 diabetic, your body's regulation system still works, not as well as it should but your chance of lowering your blood glucose to life threatening levels by exercising is highly unlikely, unlike a type 1 diabetic who, by taking insulin and exercising can run the risk of glucose depletion.

The problem can become a major one if you are insulin resistant.
Exercise is great for helping the body to become less resistant to insulin but it can make you feel very exhausted and stressed out during periods of exercise or physical activity as the body's cells are trying to become receptive once again to the insulin.




Talk to your doctor before beginning any physical activity if it will be a part of your attempt to control your blood glucose level, also monitor your blood pressure and keep a log book of your activities and results, the documentation could prove to be very helpful in evaluating your progress.

(I hope that I didn't stray too far away from your discussion)

Here are some of the benefits of exercise for type 2 diabetics:

Exercise helps control type 2 diabetes by:

Improving your body's use of insulin.
Burning excess body fat, helping to decrease and control weight (decreased body fat results in improved insulin sensitivity).
Improving muscle strength.
Increasing bone density and strength.
Lowering blood pressure.
Helping to protect against heart and blood vessel disease by lowering 'bad' LDL cholesterol and increasing 'good' HDL cholesterol.
Improving blood circulation and reducing your risk of heart disease.
Increasing energy level and enhancing work capacity.
Reducing stress, promoting relaxation, and releasing tension and anxiety.
