Type 2 Diabetes and Exercise
Exercise is very important in managing type 2 diabetes. Combining diet, exercise, and medicine (when prescribed) can help control your weight and blood sugar level.
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
- 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
How Does Exercise Affect Blood Sugar Levels?
Normally, insulin is released from the pancreas when the amount of sugar (glucose)Â in the blood increases, such as after eating. Insulin stimulates the liver and muscles to take in excess glucose. This results in a lowering of the blood sugar level.
When exercising, the body needs extra energy or fuel (in the form of glucose) for the exercising muscles. For short bursts of exercise, such as a quick sprint to catch the bus, the muscles and the liver can release stores of glucose for fuel. With continued moderate exercising, however, your muscles take up glucose at almost 20 times the normal rate. This helps lowers blood sugar levels. AT the same time insulin levels may drop in anyone not taking insulin so the risks of hypoglycemia or low blood sugar is minimized.
But intense exercise can have the opposite effect and actually temporarily increase your blood glucose levels right after you stop exercising. This is especially true for many people with diabetes. The body recognizes intense exercise as a stress and releases stress hormones that tell your body to increase available blood sugar to fuel your muscles. Â If you have diabetes you may need to check your sugar after exercise to see if this happens to you.Â

If the level is below 70 and you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.
People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.
Congratulations on taking steps to manage your health.
However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.
Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.
Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.
One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
