Blood Sugar (Glucose) Directory
Blood glucose (often called blood sugar) is normally regulated by insulin. Your blood sugar levels change throughout the day but usually don't get extremely high or low. Too high levels can damage your body's organs. Too low levels can cause dementia and even a coma or death. For those with diabetes, the pancreas doesn't produce the right amount of insulin, so blood sugar levels depend greatly on diet, and these levels must be regularly monitored. Follow the links below to find WebMD's comprehensive coverage about blood sugar and glucose levels, complications of abnormal blood sugar levels, and much more.
