Is tight blood sugar control right for older adults with diabetes?

One of the best parts of being a geriatrician (a specialist caring for older adults) is to meet individuals who are aging successfully, taking care of themselves, and taking their health seriously. Well-informed individuals usually like to know if their chronic health conditions are well controlled or not. With improved public education, it is now common knowledge that uncontrolled diabetes leads to damage to the major organs of the body, such as the heart, kidneys, eyes, nerves, blood vessels, and brain. So, it is important to ask how tightly blood glucose (also called blood sugar) should be controlled to decrease the risk of harm to these organs. Blood sugar: too high, too low, or just right? To answer this question, first let’s discuss how diabetes is different than other chronic health conditions. For example, a doctor can tell you that your cholesterol levels need to be below a certain number to lower the risk of heart disease. Diabetes is different. Diabetes is a unique condition in which both high and low glucose levels are harmful to the body. Diabetes control is measured as A1c, which reflects average blood sugar levels over the past two to three months. High glucose levels (A1c levels greater than 7% or 7.5%) over a long period can cause damage to the major organs of the body. However, medications and insulin that are used to lower glucose levels can overshoot and lead to glucose levels that are too low. Low glucose levels (known as hypoglycemia) can result in sym...
