This week our heroes are Frederick Banting and Charles Best, the two scientists who created the first effective treatment for diabetes by successfully extracting the hormone insulin from the pancreas. Thanks to Banting and Best’s work, millions of diabetics can now live long, healthy lives rather than face early, painful death.
Full Answer
What was the first treatment for diabetes discovered?
Doing this reversed diabetes and marked the discovery of the hormone insulin. They worked with two other scientists to purify insulin that they took from the pancreas of cows and produce the first treatment for diabetes. In January 1922, 14-year-old Leonard Thompson was the first person to receive an injection of insulin to treat diabetes.
What is the history of Type 1 diabetes?
Over 3,000 years ago, the ancient Egyptians mentioned a condition that appears to have been type 1 diabetes. It featured excessive urination, thirst, and weight loss.
What is the history of diabetes management in the 1920s?
Before the 1920s, there were no effective pharmacological agents for the management of diabetes. Because of this, type 1 diabetes was a fatal malady. This changed dramatically with Frederick Banting's work.
Who was the first patient to receive insulin?
Leonard Thompson was the first patient to receive insulin. He was a 14-year-old boy who weighed 65 lb, was pale, smelled of acetone, was losing hair, had a distended abdomen, and was later described as looking like the victim of a concentration camp.
Who invented the treatment for diabetes?
In the beginning of the 20th century, physicians hypothesized that the islets secrete a substance (named "insulin") that metabolises carbohydrates. The discovery and purification of insulin for clinical use between 1921–1922 by a group of researchers in Toronto—Frederick Banting, J.J.R.
Who developed insulin the first effective treatment for diabetes?
July 27 marks one of the most important days in diabetes treatment history. On that date in 1921, Dr. Frederick Banting, a Canadian surgeon and Charles Best, a medical student, successfully isolated the hormone insulin for the first time.
Who discovered treatment for diabetes in 1923?
In the early 1920s Frederick Banting and Charles Best discovered insulin under the directorship of John Macleod at the University of Toronto. With the help of James Collip insulin was purified, making it available for the successful treatment of diabetes. Banting and Macleod earned a Nobel Prize for their work in 1923.
When did treatment for diabetes start?
In 1921, Frederick Banting and Charles Best extended Minkowski's and Mering's experiment. They isolated insulin from pancreatic islets and administrated to patients suffering from type 1 diabetes, saving thus the lives of millions and inaugurating a new era in diabetes treatment.
What did Frederick Banting discover?
insulinDue to Banting's discovery of insulin, millions of people worldwide were able to extend their lives by decades. In 1923, Banting became the first Canadian and the youngest person, at age 32, to receive the Nobel Prize in Physiology/Medicine.
When was diabetes first discovered?
The first known mention of diabetes symptoms was in 1552 B.C., when Hesy-Ra, an Egyptian physician, documented frequent urination as a symptom of a mysterious disease that also caused emaciation. Also around this time, ancient healers noted that ants seemed to be attracted to the urine of people who had this disease.
Who discovered insulin in 1921?
In 1921, a young surgeon named Frederick Banting and his assistant Charles Best figured out how to remove insulin from a dog's pancreas. Skeptical colleagues said the stuff looked like “thick brown muck,” but little did they know this would lead to life and hope for millions of people with diabetes.
Who discovered insulin in 1910?
In 1910 and later in 1916, in London, Sir Edward Albert Sharpey-Schafer (1850–1935) (14) described in depth that the pancreatic islands are able to secrete a substance capable of controlling glucose metabolism, which he termed “insulin,” from Latin “insula” (“island”), with reference to the Langherans islands.

How did Joseph von Mering discover diabetes?
In 1889, Joseph von Mering and Oskar Minkowski found that removing the pancreas from dogs led them to develop diabetes and die shortly afterward. This discovery helped scientists understand the role of the pancreas in regulating blood sugar levels.
Who named diabetes?
The term "diabetes" was first coined by Araetus of Cappodocia (81-133AD). Later, the word mellitus (honey sweet) was added by Thomas Willis (Britain) in 1675 after rediscovering the sweetness of urine and blood of patients (first noticed by the ancient Indians).
How did Galen describe diabetes?
His reference to diabetes was based on Galen's texts, and he mentions that 'thin, white excessive excretion of urine indicates diabetes and that the wise men among the doctors named it chamber-pot dropsy (and the most eminent among them urinary diarrhoea) others extreme thirst' [23].
Who first mentioned diabetes?
During the third century B.C.E., Apollonius of Memphis mentioned the term “diabetes,” which may have been its earliest reference. In time, Greek physicians also distinguished between diabetes mellitus and diabetes insipidus. Diabetes insipidus has no link with diabetes mellitus.
Who was the first person to receive insulin?
In January 1922, 14-year-old Leonard Thompson was the first person to receive an injection of insulin to treat diabetes.
What did Joseph von Mering and Oskar Minkowski discover about dogs?
Image credit: Wellcome images. In 1889, Joseph von Mering and Oskar Minkowski found that removing the pancreas from dogs led them to develop diabetes and die shortly afterward. This discovery helped scientists understand the role of the pancreas in regulating blood sugar levels.
Why does diabetes cause high blood sugar levels?
Diabetes develops when the body does not produce enough insulin or cannot respond to it appropriately, leading to high levels of sugar in the blood. Managing blood sugar levels can be challenging, but ongoing research is increasing the chance of living a full life with diabetes.
Why was insulin called insulin?
He called it insulin, meaning island, because the cells in the islets of Langerhans in the pancreas produce it.
What are the benefits of insulin pumps?
The 1990s saw the invention of external insulin pumps, which, with correct use, can provide: 1 better results 2 more flexibility 3 easier treatment management
What is the cause of type 2 diabetes?
Insulin resistance is one factor that leads to type 2 diabetes. When a person has insulin resistance, their body cells lose their sensitivity to insulin and are not able to take in glucose. In response, the pancreas increases its output of insulin.
Insulin
Before the 1920s, there were no effective pharmacological agents for the management of diabetes. Because of this, type 1 diabetes was a fatal malady. This changed dramatically with Frederick Banting's work.
Biguanides
French lilac, or goat's rue ( Galega officinalis ), was used as a folk remedy for diabetes in Southern and Eastern Europe during medieval times. 7 In the early 20th century, the antihyperglycemic moiety in this plant, guanidine, was isolated. Frank et al.
Sulfonylureas
The history of the sulfonylureas (SUs) began in 1937 with the observation of the hypoglycemic activity of synthetic sulfur compounds. 10 Five years later, Marcel Janbon and his colleagues were treating patients with the antibiotic para-amino-sulfonamide-isopropyl-thiodiazole for typhoid and observed hypoglycemia.
Thiazolidinediones
Thiazolidinediones (TZDs), which are also known simply as “glitazones,” were initially introduced to the U.S. market in 1996. These agents are peroxisome proliferator–activated receptor-γ activators whose mechanisms of action are enhancement of skeletal muscle insulin sensitivity and reduction in hepatic glucose production.
α-Glucosidase Inhibitors
α-Glucosidase inhibitors (AGIs) exert a local effect on the brush border of the small intestine, inhibiting α-glucosidase enzymes, which are responsible for the breakdown of oligosaccharides, trisaccharides, and disaccharides. These enzymes include maltase, isomaltase, gluocoamylase, and sucrase.
Meglitinides
The meglitinides (also called “glinides”) have a mechanism of action similar to that of the SUs but are structurally unrelated to SUs. This class of medication lowers blood glucose levels by stimulating insulin release from the pancreas. 7 As with the SUs, glinide-induced insulin stimulation is dependent on functioning pancreatic β-cells.
Glucagon-Like Peptide-1 Receptor Agonists
The idea of an “incretin effect” was long known and based on experimental data demonstrating a greater insulin response with oral glucose administration versus intravenous glucose administration. The generalities of the incretin-insulin pathway were worked out by the 1980s.
When was diabetes first described?
Frederick Banting (right) joined by Charles Best in office, 1924 Diabetes is one of the first diseases described [1] with an Egyptian manuscript from c. 1500 BCE mentioning “too great emptying of the urine.” [2] The first described cases are believed to be of type 1 diabetes. [2] Indian physicians around the same time identified the disease and classified it as madhumeha or honey urine noting that the urine would attract ants. [2] The term "diabetes" or "to pass through" was first used in 250 BC by the Greek Apollonius of Memphis. [2] Type 1 and type 2 diabetes were identified as separate conditions for the first time by the Indian physicians Sushruta and Charaka in 400-500 CE with type 1 associated with youth and type 2 with obesity. [2] The term "mellitus" or "from honey" was added by Thomas Willis in the late 1600s to separate the condition from diabetes insipidus which is also associated with frequent urination. [2] Further history Plaque in Strasbourg commemorating the 1889 discovery by Minkowski and Von Mering The first complete clinical description of diabetes was given by the Ancient Greek physician Aretaeus of Cappadocia (fl. 1st century CE), who also noted the excessive amount of urine which passed through the kidneys.” [3] Diabetes mellitus appears to have been a death sentence in the ancient era. Hippocrates makes no mention of it, which may indicate that he felt the disease was incurable. Aretaeus did attempt to treat it but could not give a good prognosis; he commented that "life (with diabetes) is short, disgusting and painful." [4] The disease must have been rare during the time of the Roman empire with Galen commenting that he had only seen two cases during his career. [2] In medieval Persia, Avicenna (980–1037) provided a detailed account on diabet Continue reading >>
How has diabetes changed in the past 50 years?
The lives of people with diabetes has changed considerably in 50 years. They now have specific tools and easier access to information than ever before. The healthcare professionals who treat them also know more about the complexity of the disease, and which treatments work best. Pending the next medical revolution, Diabetes Québec is demanding the implementation of a national strategy to fight diabetes – a strategy founded on education, prevention, support and treatment. The last 60 years have clearly demonstrated that people with diabetes who are well informed, properly supported and treated appropriately live longer lives in better health. The discovery of insulin and glycemic control Insulin, discovered in 1921 by the legendary Banting, Best and MacLeod collaboration, is nothing short of a miracle. Worldwide, it has saved thousands of patients from certain death. Before the discovery of insulin, diabetics were doomed. Even on a strict diet, they could last no more than three or four years. However, despite the many types of insulin and the first oral hypoglycemic agents that came to market around 1957 in Canada, glycemia control – the control of blood glucose (sugar) levels – still remains an imprecise science. In the 1950s, the method a person used to control his blood glucose levels was to drop a reagent tablet into a small test tube containing a few drops of urine mixed with water. The resulting colour – from dark blue to orange – indicated the amount of sugar in the urine. Even when they monitored their patients closely, doctors realized that blood glucose levels had to be much better controlled in order to delay the major complications significantly affecting their patients’ lives: blindness, kidney disease, gangrene, heart attack and stroke.

How to treat Type 1 diabetes?
Scientists at the University of Texas announced the breakthrough, which uses a novel approach that may eliminate Type 1 diabetes and see painful insulin injections become a thing of the past. University of Texas Health Science Center doctors used a virus as a carrier to introduce insulin-producing genes into the pancreas of rodent subjects. Professor Ralph DeFronzo said researchers altered cells so they secreted insulin, but only in response to glucose — mimicking the behavior of the body’s beta cells. This study bypasses the autoimmune system by altering other pancreatic cells so they can co-exist with immune defenses — unlike beta cells, which are rejected in Type 1 patients. At the moment, Type 1 diabetes is treated by monitoring glucose levels and injecting artificial insulin several times a day. While technology has made management of the condition easier, a cure has been elusive — until now. The patent’s co-inventor, Professor Bruno Doiron, said the results had never been seen before. “It worked perfectly,” Doiron said. “We cured mice for one year without any side effects.” Doiron predicted the same low-risk response in humans. “If a Type 1 diabetic has been living with these cells for 30, 40 or 50 years, and all we’re getting them to do is secrete insulin, we expect there to be no adverse immune response.” DeFronzo said the same method of treatment has been approved almost 50 times by the US Food and Drug Administration to treat various conditions, including rare childhood diseases.

Where did the word "diabetes" come from?
Origin of the term ‘diabetes’ The term diabetes is the shortened version of the full name diabetes mellitus. Diabetes mellitus is derived from the Greek word diabetes meaning siphon - to pass through and the Latin word mellitus meaning honeyed or sweet. This is because in diabetes excess sugar is found in blood as well as the urine. It was known in the 17th century as the “pissing evil”. The term diabetes was probably coined by Apollonius of Memphis around 250 BC. Diabetes is first recorded in English, in the form diabete, in a medical text written around 1425. It was in 1675 that Thomas Willis added the word “'mellitus'” to the word diabetes. This was because of the sweet taste of the urine. This sweet taste had been noticed in urine by the ancient Greeks, Chinese, Egyptians, Indians, and Persians as is evident from their literature. History of the treatment of diabetes Sushruta, Arataeus, and Thomas Willis were the early pioneers of the treatment of diabetes. Greek physicians prescribed exercise - preferably on horseback to alleviate excess urination. Some other forms of therapy applied to diabetes include wine, overfeeding to compensate for loss of fluid weight, starvation diet, etc. In 1776, Matthew Dobson confirmed that the sweet taste of urine of diabetics was due to excess of a kind of sugar in the urine and blood of people with diabetes. In ancient times and medieval ages diabetes was usually a death sentence. Aretaeus did attempt to treat it but could not give a good outcome. Sushruta (6th century BCE) an Indian healer identified diabetes and classified it as “Madhumeha”. Here the word “madhu” means honey and combined the term means sweet urine. The ancient Indians tested for diabetes by looking at whether ants were attracted to a person's u Continue reading >>
Is insulin linked to Alzheimer's?
“What we found is that insulin is not just produced in the pan creas, but also in the brain. And we discovered that insulin and its growth factors, which are necessary for the survival of brain cells, contribute to the progression of Alzheimer’s,” says senior author Suzanne M. de la Monte, a neuropathologist at Rhode Island Hospital and a professor of pathology at Brown Medical School. “This raises the possibility of a Type 3 diabetes.” It has previously been known that insulin resistance, a characteristic of diabetes, is tied to neurodegeneration. While scientists have suspected a link between diabetes and Alzheimer’s disease, this is the first study to provide evidence of that connection. By studying a gene abnormality in rats that blocks insulin signaling in the brain, researchers found that insulin and IGF I and II are all expressed in neurons in several regions in the brain. Additionally, researchers determined that a drop in insulin production in the brain contributes to the degeneration of brain cells, an early symptom of Alzheimer’s. “These abnormalities do not correspond to Type 1 or Type 2 diabetes, but reflect a different and more complex disease process that originates in the CNS (central nervous system),” the paper states. By looking at postmortem brain tissue from people diagnosed with Alzheimer’s disease, researchers discovered that growth factors are n Continue reading >>
Who discovered the pancreatic extract?
Go to: The introduction of pancreatic extracts While Naunyn, Mering and Minkowski had focused on the pancreas as the seat of diabetes, Eugene Opie (1873–1971), a pathologist at Johns Hopkins University, Baltimore, made a further important advance by establishing the association between diabetes and destruction of the islets of Langerhans,10,11 and this observation stimulated research into the effects of administering pancreatic extracts. During the early 1900s in Aberdeen, Scotland, John Rennie and Thomas Fraser studied the effects in five patients with diabetes of giving an extract of “principal islets” (large islets forming separate globular aggregates made up mostly of endocrine pancreatic tissue present in some fishes (and snakes), but no convincing benefit was detected.12 At around the same time, in Belgium, J De Meyer (1878–1934) discovered an internal secretion produced by the islets,13,14 but his attempt to extract it from pancreatic tissue also failed. In Berlin, Georg Ludwig Zuelzer extracted animal pancreas with alcohol and saline, and, after first experimenting on rabbits, he gave injections of the extract to a dying diabetic patient. Although there seemed to be an initial improvement (no biochemical measurements were made), the extract was used up within a few days and the patient relapsed and died. He carried out further experiments,15 injecting five diabetic patients with pancreatic extract, but impurities caused fever. He spent a further three years trying to purify his extract. Zuelzer's method of extraction was subsequently developed by the pharmaceutical firm Hoechst and Zuelzer can justly be regarded as the first person to have achieved even partial success in finding a pancreatic extract with potential therapeutic value.16 Meanwhile, in Chic Continue reading >>
Can dapagliflozin help with diabetes?
Researchers have discovered that a drug commonly used to treat type 2 diabetes patients could also benefit those with type 1 diabetes. A study by the University of Buffalo has revealed that type 1 patients given dapagliflozin - a medication traditionally given to type 2 sufferers - experienced a significant decline in their blood sugar levels. Until now, there hadn’t been a significant development in treatment for type 1 diabetes since the discovery of insulin in the 1920s. Both type 1 and type 2 diabetes sufferers have higher than normal blood sugar levels. When the drug was taken in addition to insulin - needed by type 1 diabetics every day to survive - there was an improvement in blood glucose levels. However, the former is where the body’s immune system attacks and destroys insulin-producing cells, while the latter is caused when the body doesn't produce enough insulin, or the body's cells don't react to insulin. In the study, researchers looked at 833 participants aged between 18 and 75 who had poorly controlled blood sugars for 24 weeks. It was the first time dapagliflozin had been tested for effectiveness and safety in treating type 1 globally - the study took place in 17 countries. When the drug was taken in addition to insulin - needed by type 1 diabetics every day to survive - there was an improvement in blood glucose levels. Fri, August 19, 2016 Diabetes is a common life-long health condition. There are 3.5 million people diagnosed with diabetes in the UK and an estimated 500,000 who are living undiagnosed with the condition. "Our paper provides the initial signal that dapagliflozin is safe and effective in patients with Type 1 diabetes and is a promising adjunct treatment to insulin to improve glycemic control," said Professor Paresh Dandona, a study aut Continue reading >>

Who discovered insulin?
A. (1923) J. Biol. Chem. 57, 709–723) The story of the discovery of insulin has been well chronicled beginning with a young physician, Frederick Banting, in London, Ontario, imagining that it might be possible to isolate the internal secretions of the pancreas by ligating the pancreatic ducts to induce atrophy of the acinar cells and thereby minimize contamination of the tissue extract with digestive enzymes. Banting presented his suggestion to J. J. R. Macleod, a distinguished physiologist at the University of Toronto who provided Banting with a laboratory for the summer and some dogs for the experiments. Macleod also assigned Charles Best, a young student, to work as Banting's assistant for the summer. During the summer of 1921, Banting and Best made remarkable progress, and by fall they had isolated material from pancreas extracts that dramatically prolonged the lives of dogs made diabetic by removal of the pancreas. In the winter of 1922, Banting and Best treated their first human patient, a young boy, who's life was saved by the treatment. This was a stunning accomplishment. Consider that from the start of the research in the summer of 1921 to treating a human patient successfully in the winter of 1922, the pace, especially by current standards for clinical treatments, was remarkable. With that achievement, Macleod, who had been initially unenthusiastic about the work, assigned his entire laboratory to the insulin project. He also enlisted the Eli Lilly Company to aid in the large scale, commercial preparation of insulin although the University of Toronto received the patent for insulin production. By 1923, insulin was available in quantities adequate for relatively widespread treatment of diabetes. Although Continue reading >>

What was the most significant complication from diabetes before the invention of insulin?
(University of Chicago Press, 1984). 304 pages. The most significant complication from diabetes, before the invention of insulin, was falling into a hyperglycemic induced coma. Pioneers such as Drs. Fred Allen and Elliott P. Joslin were able to help some diabetics prolong their life by as long as a year or two with careful management of carbohydrate intake. Before insulin, dying from diabetes meant starving to death and eventually falling into coma. Diabetes patients were in such painfully malnourished states, often weighing under 70 pounds upon admittance to a hospital, that the only tragic figures who could remind these doctors of their earliest patients were victims of concentration camps during World War II or mass famine in Africa. The highlights one of those incredible moments in medical history where a new treatment literally raises people from the dead. Author Michael Bliss brilliantly illustrates one of the most significant medical findings in modern medicine while paying special attention to the facts explaining the controversies associated with its discovery. Insulin was discovered at the University of Toronto and Bliss’s position as a professor of history at the university enables him to utilize previously unpublished and privately held documents. He uses vivid detail and skillfully paints a picture of the significant gains and trying mishaps along the tenuous path to insulin discovery in the early 1900s. The story was written by Bliss to serve as a “readable and definitive history of the discovery of insulin,” aimed at academics and lay readers alike. It is a compelling and heartwarming story that any reader, not just medical professionals and diabetics, could enjoy. Some passage Continue reading >>
How long can a person with diabetes live?
Now people with Type 1 diabetes can expect to live around 68 years on average. One big reason why: the discovery of the hormone insulin by a team led by Frederick Banting, an early-20th-century scientist from Canada, which revolutionized treatment for the disease. Today, we celebrate Banting’s 125th birthday with a Google Doodle in his honor and with World Diabetes Day. Banting and his colleagues cracked a mystery that was thousands of years old Diabetes is one of the first human diseases on record. Ancient Egyptian manuscripts from as far back as 1500 BC mention a disease “characterized by the ‘too great emptying of urine.’” Around 500 BC, an Indian physician described patients with urine so sweet and sticky it attracted ants. These ancient reports were likely of Type 1 diabetes, the autoimmune version of the disease where antibodies damage the cells in the pancreas that secrete insulin. Insulin is the hormone responsible for taking sugar out of the bloodstream and transferring it into the body’s cells, where it can be used for energy. When the body stops making insulin, blood sugar rises. And unchecked high blood sugar can lead to a range of complications — from deteriorating eyesight to nerve damage to the buildup of chemicals called ketones in the blood. Ketones at high levels can be poisonous, causing the blood to turn acidic. (In Type 2 diabetes, the pancreas still produces insulin, but the body has become resistant to its effects. It’s a metabolic disease, rather than an autoimmune disease.) While ancient physicians recognized that the disease was a result of mismanagement of the body’s sugar, they didn’t know what caused it. (D Continue reading >>
Who discovered insulin?
Insulin was discovered by Sir Frederick G Banting (pictured), Charles H Best and JJR Macleod at the University of Toronto in 1921 and it was subsequently purified by James B Collip. Before 1921, it was exceptional for people with type 1 diabetes to live more than a year or two. One of the twentieth century’s greatest medical discoveries, ...
Who was the first insulin maker?
Banting and Best set about improving their techniques for the production of insulin so it could be made in much larger quantities. In May 1922, Eli Lilly become the first manufacturer to mass produce insulin.
How long did Banting treat dogs with insulin?
By November, they’d successfully treated a dog with diabetes with their insulin extract for 70 days.
When did Leonard Collip get his second injection?
Collip worked day and night on purifying the extract even further, and Leonard was given a second injection on 23 January 1922 .
Who provided Banting with the labs needed to conduct their experiments?
Macleod provided Banting with the labs needed to conduct their experiments and brought in a research student, called Charles Best, to help out. Best specialised in testing blood to check glucose levels. This would be the way they would know whether their insulin extracts were having any benefit.
Who discovered that insulin is slower to deteriorate?
The challenge was to find a way to extract insulin from the pancreas without it being destroyed in the process. In October 1920, Frederick Ban ting – a Canadian surgeon – read an article that suggested insulin-producing cells in the pancreas are slower to deteriorate than other pancreas tissue.
Who won the Nobel Prize for Physiology in 1923?
In recognition of their life-saving discovery, Banting and Macleod were jointly awarded the 1923 Nobel Prize in Physiology or Medicine. Banting split his half of the Prize money with Best, and Macleod split the other half of the Prize money with Collip.
