Blood glucose during exercise
Common Questions and Answers about Blood glucose during exercise
blood-glucose
I need to clarify my earlier post. Exercise does burn energy, and eventually exercise lowers blood glucose. When I mentioned "cardio level aerobic exercises" I meant this to be "rigorous" exercises. For example cardio aerobic, fast treadmill workouts, or even continuous pumping of weights.
In a way, your liver "has a mind of its own" and continues to produce glucose while you exercise.
However, intense exercise can have the opposite effect and actually increase your blood glucose levels. The body recognizes intense exercise as a stress and releases stress hormones that tells your body to increase available blood glucose to fuel your muscles. If your glucose levels exceed normal levels discuss with your doctor medication or medication adjustment.
It's good to see that you are trying to manage your glucose levels b4 they get out of control.
An OGTT requires you to be sedentary 2 hours post test. Being active 1 hour post defeated your "homemade" test. See this link http://en.wikipedia.org/wiki/Glucose_tolerance_test
Q: "What can be the normal glucose level after 3-4 hours lunch or dinner time"
A: Glucose peaks 2-3 hours after meals where the normal value is <180 mg/dl and the optimum is <140 mg/dl.
They need to control their blood sugar with changes to diet and exercise and often medication. Do you take any medications for your blood glucose?
If you do not understand what changes you need to make, you should speak to your doctor about what is recommended for you specifically. Your doctor may have a sample diet menu or be able to recommend a nutritionist to help you understand the proper diet.
My daughter is 16 and is a very brittle diabetic. Every time she attempts to do any exercise, her blood sugar sky rockets! She can just do sit ups and stretches and her sugar can go from 135 to 450 in a matter of minutes. She has to take insulin before and check her sugar before, during and after exercise. It isn't the same for every diabetic, but if her blood sugar doesn't do as my daughters does, then it is the best thing for a diabetic.
In the fast test you are instructed not to eat for a certain number of hours, your blood glucose level is measured, you drink a specific amount of glucose, and then, for a number of hours at specific intervals your glucose levels are measured.
You should be a "little nervous" and making an appointment for such an evaluation should be a priority. The blood sugar levels does not fall because "you have not been eating properly".
m finding it extremely difficult to exercise without having to eat first to prevent a low blood glucose, eat immediately afterward because I have a low blood glucose, or having a high glucose afterwards followed by a low bg later. I'm currently using an insulin pump and have tried several things like suspending it an hour before and during exercise, changing to a temp. basal afterward, and at times giving a correction bolus when my bg jumps from 5 mmol/L to 18 mmol/L after certain workouts.
I always take 2 or 3 pulkas or chapathis during night every day and i dont eat rice during night.. But whenever i check the blood glucose levels with the glucometer, i find that the fasting values are not within the range of normal values viz 110 for fasting. but the post lunch levels always within the normal range of viz 140.The random levels always varies from 125 to 150. Kindly advise me whether i am diabetic and do i have to take medicine for diabetes?
Also, exercise takes some glucose out of the body to use for energy during and after exercise which also lowers blood sugars. So instead of suspending, you may want to use a temp basal.
Many times the sugar goes up right after exercise due to the glucose being released from the muscles. One might need a temp basal after exercise also. The only way to know is trial and error as each person is different.
The muscle exercise in the legs is extreme (and provides my heart the most benefit) but I find my blood glucose levels do not behave at all as they do when I exercise normall). I begin exercise with a BG level of 130-140, and end with one of 280 to 340 on a hard riding day. On a less strenuous day, I consume 16-20 ounces of O.J. and barely keep above 100. I will be modifying my routine with mid-ride blood checks from now on. Thank you, Yumin, for the observation and you, LRS, for the insight.
Here is a table that lists blood glucose ranges for adults with diabetes:
Glycemic control
A1C
<7.0%
Preprandial plasma glucose (before a meal)
70–130 mg/dl (5.0–7.2 mmol/l)
Postprandial plasma glucose (after a meal)
<180 mg/dl (<10.
The second path is around the types of carbs you take while exercising. Glucose tablets are an excellent way to raise blood sugar quickly, because they are made of the most basic form of glucose, and it gets absorbed very quickly. But I know many people that do not like them. I met a marathon runner who works for Animas who was diagnosed when he was a kid. During marathons, he uses packets of honey (like what you'd get at a restaurant).
The University of Michigan Health System advises that exercise can result in either an increase or a decrease in blood sugar levels. During exercise, insulin becomes more efficient. This effect can persist, lowering blood sugar levels for hours afterward. An hour of afternoon exercise may lower glucose levels until the next morning, affecting the fasting blood sugar test. Exercise can also affect glucose levels by releasing adrenaline. This raises blood sugar temporarily.
HI,
First congrats to your husband for doing such a great job with exercise and diet changes--those are very difficult to implement, so excellent work!
His A1C is overall very good, although not entirely "normal" as in "not diabetic." His average glucose is consistent with this A1C. He could be higher during the night as well as after meals so those are two areas you could investigate.
By eating at night you may be able to help your morning blood sugar be a bit lower. When you have extended fasting your liver can put out glucose. By eating a small snack you may be able to prevent your liver doing this. hope this helps. Please come back and let us know how you're going.
Often diabetes in preganncy will get worse as the pregnancy progresses (insulin resistance increases as the pregnancy progresses and the placenta grows).
