The discovery of insulin revolutionized the treatment of diabetes, leading to significant advancements in managing the disease.
The historical perception of diabetes has shifted over time, from being associated with specific groups to recognizing its prevalence across different racial and ethnic backgrounds.
Presently, there have been significant developments in diabetes management, including technologies like continuous glucose monitors and new drugs for type 2 diabetes.
Understanding the underlying mechanisms and risk factors for diabetes, such as sedentary lifestyle and obesity, is still incomplete, highlighting the need to address environmental factors and societal structures.

The Discovery of Insulin
Frederick Banting, a struggling physician, was inspired by a scientific paper to develop a method for isolating the internal secretion of the pancreas. He partnered with J.J.R. Macleod, an expert in diabetes, and together they conducted experiments on dogs to extract the pancreatic secretion. Banting and Charles Best, an undergraduate assistant, performed surgeries on the dogs and observed the effects of diabetes. They eventually succeeded in producing the internal secretion from degenerated pancreases and used it to treat diabetic dogs. This marked a major breakthrough in the treatment of diabetes.
Early Recognition of Diabetes
Diabetes has been recognized by ancient cultures for thousands of years. Ancient writings and texts mentioned symptoms such as excessive urination and sweet urine, indicating high blood glucose levels. Over time, the condition became better understood, especially in terms of the role of the pancreas. In the 19th and early 20th centuries, the disease was treated with starvation diets or with medications like opium, but none offered a cure or effectively managed the disease.
Challenges and Struggles in Diabetes Treatment
Before the discovery of insulin, treatment options for diabetes were limited. Bleeding and opium were often used, but their effectiveness was questionable. Starvation diets emerged as a popular method, although they were extremely difficult to sustain. Many patients experienced severe weight loss and even death from these diets. The need for more effective treatments was urgent, as the available options provided little relief for patients suffering from diabetes.
The Evolution of Diabetes Treatment
The discovery of insulin revolutionized the treatment of diabetes. Researchers like Moses Barron, Oscar Minkowski, and Nicolae Paulescu contributed to the growing understanding of the role of the pancreas and its internal secretion. However, it was Frederick Banting and his team who successfully isolated and used insulin to treat diabetic dogs. This development marked a significant milestone in diabetes treatment and paved the way for future advancements in managing the disease.
Development and Success of Insulin Treatment
The podcast highlights the development and success of insulin treatment for diabetes. It explains that after numerous failures and the deaths of dogs during experiments, researchers were finally able to extract pancreatic secretion and successfully treat diabetic dogs. This led to the recognition of the potential of insulin for humans. However, tensions arose between researchers due to credit disputes and disagreements over experimental approaches. Despite the drama and personal rivalries, insulin had a profound impact on the lives of people with diabetes, profoundly improving their quality of life while also presenting ongoing challenges in terms of affordability and access.
Historical Perspectives on Diabetes
The podcast explores the historical perspectives on diabetes, highlighting how the disease was initially associated with Jewish individuals in the late 1800s before being tied to moral failings and societal decay in the early 1900s. The narrative shifted again to classify diabetics as individuals from middle and upper-class backgrounds. The perception gradually changed when statistical data became available, showcasing the prevalence of diabetes across different racial and ethnic groups. The belief of immunities in certain groups, such as Black and Native Americans, led to misrepresentations and a failure to understand the role of poverty and social determinants of health. Over time, the understanding of diabetes has evolved, with a focus on genetic components and environmental factors as contributors to the disease.
Current Understanding and Advances in Diabetes Management
The podcast discusses the present understanding and advances in diabetes management. For type 1 diabetes, the primary treatment remains insulin, but there have been significant developments in technologies like continuous glucose monitors and insulin pumps, improving glucose control. Type 2 diabetes has seen a multitude of new drugs targeting insulin resistance and enhancing tissue sensitivity. Researchers have also investigated dysfunction in the hypothalamus as a potential cause for elevated set points in blood glucose levels. However, the underlying mechanisms for the development of diabetes and its various risk factors, such as sedentary lifestyle and obesity, are still not fully understood. The podcast emphasizes the importance of addressing environmental factors and societal structures in tackling diabetes.
Almost everyone is familiar with diabetes mellitus in some way. Whether we know family or friends that have been diagnosed with the condition or we’re directly impacted ourselves, diabetes mellitus has become a household name. And this is perhaps not surprising given its extremely high prevalence - nearly 9% of adults around the globe are estimated to live with the disease. But although we may know someone with diabetes, how much do we know about diabetes itself? How does it work? Why does it cause the acute symptoms and long-term complications it does? Where does an infamous scientific rivalry fit into the story of diabetes? How long have humans been dealing with this disease, and how far has treatment come since the early days of diabetes? And importantly, how has our perception and portrayal of diabetes changed over the course of its history? In this episode, we seek to answer all these questions and many more about the globally-prevalent diabetes mellitus.
