After a meal, carbohydrates become glucose and enter your blood-so why does blood sugar stay high in diabetes? Your pancreas releases insulin, a hormone that helps glucose reach your cells and keeps blood sugar balanced. That handoff helps keep blood sugar in balance. Diabetes Mellitus is a condition in which blood glucose stays above normal. The issue isn't glucose being made. It's too little insulin, or your body not responding well to it. As a result, glucose builds up in your blood. When high blood glucose stays uncontrolled for a long time, it can harm your eyes, kidneys, nerves, and heart. Early diagnosis, suitable lifestyle changes, and appropriate treatment are important. So blood sugar stays high when insulin can't keep that balance-because there isn't enough, or your body doesn't respond to it.
