An estimated 283,000 Americans under the age of 20 have diabetes, meaning their bodies either do not produce insulin or can’t use it properly. Insulin is a hormone that helps the cells in our bodies absorb the glucose (sugar) in our blood, which we use for energy.
Jennifer Sherr, MD, PhD, a Yale Medicine pediatric endocrinologist, who has type 1 diabetes herself, describes insulin as a key that unlocks our bodies so that the food and nutrients we eat can be metabolized and used as fuel for our bodies.
“In type 1 diabetes, it’s an autoimmune process. For some reason, your body sees insulin-producing cells within your pancreas as being foreign, so it starts attacking those cells,” Dr. Sherr says. “For youth with type 2 diabetes, we have a different situation. It’s an issue with insulin resistance. You still have the keys, but they are the wrong shape.”
