Early Descriptions of Diabetes in Ancient History
The history of diabetes dates back to ancient civilizations. Early descriptions of the disease can be traced to ancient Egypt, with further observations by Greek and Arabic physicians such as Hippocrates, Aretaeus of Cappadocia, and Avicenna. The term "diabetes" itself first appeared in the 3rd century BC, described as a condition where ingested liquids were rapidly expelled through urine, highlighting the disease’s hallmark symptom of excessive urination 48.
The Path to Understanding Diabetes and the Pancreas
By the late 18th century, the term "diabetes mellitus" was introduced, distinguishing the sweet-tasting urine characteristic of the disease. In the 19th century, research began to focus on the pancreas. In 1869, Paul Langerhans discovered the pancreatic islets, which would later be recognized as the source of insulin. In 1889, Minkowski and von Mering demonstrated that removing the pancreas from dogs caused diabetes, confirming the organ’s crucial role in the disease 15.
The Discovery of Insulin: A Medical Breakthrough
The early 20th century saw many attempts to isolate the active substance in the pancreas that could treat diabetes, but these early extracts were too toxic for human use. The major breakthrough came in 1921, when Frederick Banting, Charles Best, James Collip, and John Macleod at the University of Toronto successfully extracted insulin and used it to treat diabetes in humans. Their first patient, Leonard Thompson, received insulin in January 1922, resulting in a dramatic improvement in his condition 125678910.
Impact and Evolution of Insulin Therapy
The discovery of insulin transformed diabetes from a fatal disease to a manageable chronic condition. Insulin became the first hormone to be purified for human use, and over the following decades, advances in its purification, structural characterization, and genetic sequencing led to improved formulations and delivery methods. These developments have enabled people with diabetes, especially children, to live longer and healthier lives 36910.
Ongoing Advances and Future Directions
Over the past century, insulin therapy has continued to evolve, with innovations such as continuous glucose monitoring and semi-automated insulin delivery systems. Research is ongoing to develop even more advanced insulin formulations, including once-weekly and glucose-responsive "smart" insulins, aiming to further improve the quality of life for people with diabetes 36810.
Conclusion
The history of diabetes discovery is a story of centuries of observation, scientific curiosity, and perseverance. The identification of insulin in 1921 stands as a pivotal moment, saving countless lives and inspiring ongoing research and innovation in diabetes care. Despite these advances, challenges remain in ensuring equitable access to insulin and diabetes management worldwide, but the legacy of discovery continues to drive progress.
