Exercise before blood glucose test
Common Questions and Answers about Exercise before blood glucose test
blood-glucose
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. Physical exertion or other activities that cause excitement may increase fasting sugar levels if performed shortly before the test.
The tests you should be asking your doctor about, for example, is what is your glucose (blood sugar). If the glucose is elevated you can be diabetic. Also, ask about your total lipid panel- this would include cholesterol, low density and high density lipids. If these are elevated you can be at risk for heart disease, etc.
I would suggest you might sit down with your doctor and just have him explain and answer all your questions.
You can control your blood sugar levels with diet and exercise (sometimes medication is needed). You don't have to give up all carbs/starchy foods but you do need to find a balance between the carbs you eat and protein. You need to eat more frequently to maintain stable levels 3 meals and 3 snacks a day. There are a lot of things you can still have in moderation... it gets easier the longer you are on the diet.
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.
Hi, first, welcome to this forum. I'm glad you posted.
Its time you saw another doctor. For a doctor to discourage glucose testing unless the patient is on insulin is horribly wrong. He/she sounds like a quack. It is important to monitor your blood sugar (glucose) on a regular basis to understand how well you are controlling your diabetes. Your above 300 mg/dl readings are high and getting real close to a dangerous level where diabetes complications start to set in.
Today about 20 minutes after my lunch I started sweating, feeling weak, heart racing, etc. I checked my blood sugar and it was 71 after eating a chicken salad, salad. I checked it before eating and it was 77 so why would it go down after eating a salad and a few wheat crackers? 71 is normal but again I felt horrible, weak, shaky, anxiety, etc. Could this be something other than Hypoglycemia? Before I had lunch I ran 2.5 miles on the treatmill and felt fine so this is beginning to puzzle me.
If you have poor release of insulin, then after exercise the blood glucose can rise. While exercising the brain gets a signal to increase blood glucose to meet the extra body demand. If this increased sugar is able to trigger an increased insulin response, the blood sugar gets lowered. Otherwise, it remains high.
You should get GTT or glucose tolerance test, fasting blood sugar, post prandial sugar done and glycosyltaed hemoglobin measured to know whether you have diabetes or not.
Like foods, there are different types of exercises that affect the body differently by how they are performed. The key is to start slow and easy then build up the routine over time. Increase time and motion only when your body feels comfortable doing so. With continuous moderate exercise your muscles use up excess glucose. However, strenuous exercise can have the opposite effect as your body may release stress hormones that tells your body to release available glucose for energy.

Hello Doctor, I was diagnosed with thyroiditis last year at age 57, but I'm not sure what kind. I started out hyper which my doctor treated with beta blockers to slow my heart rate. Then I went hypo, and I've been on 50 mcg of Synthroid for the past year. My last TSH was 2.98. My question is regarding blood glucose. My last fasting test was 127. I've always tested under 100. I'm fearful of developing diabetes. Is the synthroid causing my blood sugar to rise?
Since we have no mention of a home glucose test meter in your post my question to you is how do you know when your blood glucose is going down? And when? See this link on when to test your blood glucose before, during, and after a workout. http://www.mayoclinic.com/health/diabetes-and-exercise/DA00105
As Sally mentioned, it is best to monitor your blood glucose with a home test meter.This is the only way to know, besides being tested at the doctors office, your glucose levels.
Your symptoms may not have anything to do with diabetes but the best way to find out is to have a 2-hour glucose challenge test done. This will not only tell you if you have diabetes but also milder forms of glucose handling problems like Impaired Glucose Tolerance (which is also associated with diabetes later in life).
In the meantime try to increase your exercise to 30-45 minutes five times a week of at least a brisk walk. Cutting sweets is always a good idea, as well as saturated fats.
Typically this is a fasting test in which you are supposed to have a certain number of hours before consuming food. Usually, fasting begins at midnight for a test the next day. Your sugar by the standards of your lab states it was high on your first test. The repeat is normal. I am not sure if that was a fluke. I'd probably get it checked in another 6 months to see where you are at. This article may help you understand how blood sugar can fluctuate and when it is normal. https://www.
Normal reading is below 6%. A fasting glucose test only measure your glucose at that time, not over a period of time. The HgbA1c provides a better picture to your doctor.
Here are your Diabetes symptoms, symptoms of type 2 Diabetes
(hyperglycemia):
* Increased thirst
* Increased urination
* Increased appetite
* Fatigue
* Blurred vision
* Slow-healing infections
* Impotence in men
Regular exercise is especially important for people with diabetes and pre-diabetes.
