"Exercising is the most underused treatment and it's so, so powerful," said Sharon Movsas, RD, a diabetes nutrition specialist at the Clinical Diabetes Center at Montefiore Medical Center in New York City.
For most people with diabetes, exercise is a safe and highly recommended way to reduce the risk of complications. However, check with your doctor to make sure you don't have heart problems, nerve damage, or other issues that need special consideration when you are working out.
How exercise affects blood sugar
In general, blood sugar drops after exercise and is lower for the next 24 to 48 hours, says Movsas. "If I take a blood sugar reading after aqua-aerobics, I usually notice it's down," says David Mair, 79, of Marquette, Mich.
When you exercise, your muscles become more sensitive to insulin and absorb more glucose from the blood. However, like many aspects of type 2 diabetes, the response can be highly personal. Exercise can sometimes boost blood sugar. At first, you'll need to test your blood sugar before, after, and sometimes during exercise, to see how your body responds).
Exercise also helps lower blood pressurean important benefit since high blood pressure can contribute to heart attacks, strokes, eye problems, kidney failure, and other type 2 diabetes complications.
