what’s so bad about high blood sugar?Sugar may be sweet, but the last thing you want is it running rampant through your bloodstream with no place to go. And that’s exactly what happens when diabetes isn’t controlled. In people who don’t have diabetes, insulin opens the gates between blood vessels and the cells in the body’s muscles, allowing glucose to be used by those cells for energy. But people with diabetes either no longer have the ability to make insulin (Type 1) or it no longer works properly (Type 2). If the disease isn’t controlled, high blood sugar, or hyperglycemia, can result. When glucose remains in the bloodstream too long, the sugar actually coats the red blood cell, and that makes the blood cell stiff. That interferes with blood circulation, causing cholesterol to build up on the inside lining of the blood vessel. It can take years for the damage to become apparent, but smaller, more fragile blood vessels such as those in the eyes, kidneys and feet are most at risk. Adding to the complications is the fact that bacteria thrive on glucose. Combine that with the loss of sensation due to glucose-related nerve damage, and you have a recipe for severe foot problems that could result in amputation. Eventually, even larger blood vessels can be affected, and even blocked, causing strokes and heart attacks. Another problem that can result from hyperglycemia is called “ketosis.” This condition is caused by the body breaking down an excessive amount of fat to use as energy instead of relying on glucose — which it can’t use because of insulin problems. When too much fat is broken down too quickly, it produces acidic ketones. When too many build up in the bloodstream, the life-threatening condition ketoacidosis can occur. Certainly, these and other complications from diabetes are serious, and knowing what kind of damage uncontrolled blood sugar can cause is important. But the good news is that diabetes is one of the few diseases that you actually can control. Eating healthfully, getting exercise, maintaining a healthy weight and keeping a close eye on blood sugar levels all go a long way to reducing the risks associated with diabetes.
