August 2021 marks 100 years since the discovery of insulin. Before insulin was discovered, a diagnosis of diabetes would be seen as a death sentence. The only remedies available at that time were very restrictive low-calorie and low-carbohydrate diets. These regimens could extend patients’ lives by a few years, but they would still ultimately succumb to the disease. They also made diabetic patients very weak and could even lead to starvation.
Simply put, the discovery of insulin helped save many lives—as it continues to do today.
