The Importance of Insulin

August 14, 2016 12:00 PM

Insulin is an endocrine hormone produced by the pancreas that is crucial to the transport of glucose from the bloodstream into the cells of the body. If there is excess glucose circulating in the bloodstream, insulin also assists the liver, muscle, and fat cells in storing it for later use. Essentially, insulin is the “key” that unlocks the cell for glucose to enter. Glucose is a simple sugar that is an important energy source for metabolism.

If not enough insulin is present in the body or if there is “insulin resistance”, glucose remains in the bloodstream and can reach dangerous levels. This condition is called hyperglycemia and is a component of diabetes. If sugar metabolism is not controlled it can have dangerous consequences for the heart, brain, and nervous system.

As an endocrine hormone, insulin has many additional functions and is involved in building muscle, brain functioning, and managing the breakdown of fats. Disruptions in insulin function can create diverse symptoms and complications across the body and its systems. Endocrinologists are experts in the role of insulin in the body.
