What Is Insulin?
The insulin your body makes naturally is a hormone. Insulin helps move sugar from the blood into the body’s cells, where it can be used for energy. The pancreas releases insulin all the time. The pancreas is an organ that sits near the stomach. Special cells in the pancreas, called beta cells, make insulin. In between meals, the pancreas releases a low level of insulin to help the body produce energy. When you eat, your blood sugar (also known as blood glucose) rises. The pancreas releases more insulin to take sugar from the food you eat and bring it to the cells to be changed into energy. This brings the blood sugar level in the blood back down. Insulin works like a key, unlocking cells to help deliver sugar from the blood. Every cell in the body has a lock on its cell wall, called a receptor. Insulin fits into that lock like a key, allowing sugar to enter the cells. When the body is not able to make enough insulin, blood sugar is locked out of the cells, causing it to stay in the bloodstream. This leads to blood sugar building until the levels are too high, which is also called hyperglycemia. This extra sugar is what makes people feel the symptoms of diabetes, such as often fee Continue reading >>
