Prediabetes Is Common, and Importantly, Reversible

Prediabetes is like an alarm clock. You can hit the snooze button and go back to sleep. Or you can use it as a signal to get up and get active. But what exactly is prediabetes, and how do you know if you have it? The condition occurs when blood sugar levels are consistently higher than normal, but not yet to the level for diagnosis as type 2 diabetes. High blood sugar is caused when cells can’t respond normally to insulin, a hormone made by your pancreas that acts like a key to let blood sugar into cells for use as energy. Higher and higher demands to make more insulin overwhelm the pancreas, leading to prediabetes.
