What is the origin of the term insulin?
In 1909, Belgian physician Jean de Mayer hypothesized that the islets secrete a substance that plays this metabolic role, and termed it "insulin", from the Latin insula ("island"). Sir Edward Albert Sharpey-Schafer independently proposed the same in 1916, not knowing at the time that de Meyer had made the same suggestion a few years prior.

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.
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.
How was diabetes diagnosed in the 1960s?
Urine strips in the 1960s and the automated 'do-it-yourself' measurement of blood glucose through glucometers, produced by Ames Diagnostics in 1969, brought glucose control from the emergency room to the patient's living room.

Sir Frederick Banting, a physician and scientist, was the co-discoverer of insulin, a hormone of critical importance in regulating blood sugar levels. When insulin action is deficient, one develops diabetes mellitus.
How did Frederick Banting make insulin?
Banting's plan was to tie up the pancreatic ducts of laboratory dogs until the cells that produce the enzymes degenerated, leaving the sturdy islet cells alive. He would then extract the residue.
What did Frederick Banting say about insulin?
Banting had an idea to intentionally ligate pancreatic ducts, allowing time for the acinar cells to degenerate, leaving just the islet cells. He posited that isolating this internal secretion, which was already proven to help metabolize sugar, could be a treatment for 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.

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.

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. The discovery of insulin in 1922 marked a major breakthrough in medicine and therapy in patients with diabetes. Long before the discovery of insulin, it was hypothesized that the pancreas secreted a substance that controlled carbohydrate metabolism (5). For years, attempts at preparing pancreatic extracts to lower blood glucose were ...

What were the effects of insulin on diabetes?
This resulted in some improvement of glucosuria and acidosis, decreased coma, and delayed death among children with diabetes. All diabetics were advised to decrease their sugar and dietary starch intake, and those who were obese were advised to lose weight. Insulin.
Where did diabetes originate?
The earliest description of diabetes appeared in a collection of medical texts in Egypt written around 552 BC, the Ebers Papyrus(1, 2) . Diabetes mellitus and its medicinal remedies were described in ancient India and China (1).
What is the significance of the discovery of pancreatic crude extracts?
The discovery of pancreatic crude extracts gave hope to patients with diabetes mellitus. The subsequent development of precisely engineered insulin analogs, which are more physiologic, improved diabetes control and reduced or delayed complications. Insulin continues to be the cornerstone of therapy.
Basic research pointed to the pancreas
Diabetes had been known since antiquity. The first symptoms were often a prodigious thirst and urination. Within weeks the patient would be losing weight. Within months, the patient would enter a coma, then die. For centuries, no one had any clue about what caused diabetes.
Isolating the insulin
In 1920, Fred Banting, a small-town doctor in London, Ontario, had an idea. He thought that he could surgically tie off the ducts between the pancreas and the digestive system in an animal. Wait for a few weeks, while the part of the pancreas that produces those digestive enzymes decays, then remove the pancreas completely.
Insight from a brewery
But disaster struck when Collip failed to purify larger batches of insulin. He was puzzled why, following the exact same recipe as he’d used before, his preparations lacked insulin. J.J.R. Macleod now turned to Eli Lilly and Company, a commercial firm in Indiana that made medicinal capsules, for help.
Vanquishing a human disease
By May 1924, diabetes was no longer a fatal disease. Physician Joseph Collins, writing in The New York Times, described it this way: “One by one the implacable enemies of man, the diseases which seek his destruction, are overcome by Science. Diabetes, one of the most dreaded, is the latest to succumb .”

Why is insulin important for diabetes?
Insulin is central to the treatment of diabetes, as all types of diabetes occur due to the body’s inability to use blood sugar efficiently as a result of insufficient, ineffective, or nonexistent insulin supplies. The innovative scientists who discovered insulin won a Nobel prize, but the discovery also caused controversy.
Why did Banting fail to find insulin?
He observed that other scientists might have failed to find insulin because digestive enzymes had destroyed the insulin before anyone could extract it. Banting’s plan was to tie up the pancreatic ducts of laboratory dogs until the cells that produce the enzymes degenerated, leaving the sturdy islet cells alive. He would then extract the residue.
What was the purpose of the Macleod study?
Macleod helped with the general structure of the research, and Best specialized in the chemical testing of blood to check glucose levels. The research commenced on 17th May, 1921. The aim was to ligate a dog’s pancreas until it broke down and started to produce the extract of islets.

How did the Greeks know about diabetes?
The understanding of diabetes has been developing for thousands of years; even the ancient Greeks knew about it and would diagnose diabetes by tasting urine. The awareness that certain states of urine and levels of thirst related to blood sugar levels has grown over the centuries.
How much did the extract drop in blood sugar?
The first test involved a 14-year-old boy with severe diabetes. While the extract led to a drop in blood sugar from 0.44 percent to 0.32 percent and a small reduction in the amount of glucose excreted, an abscess developed at the site of injection and ketone levels, another indicator of diabetes, did not change.

What is the name of the disease that is referred to as diabetes?
The condition known today as diabetes (usually referring to diabetes mellitus) is thought to have been described in the Ebers Papyrus (c. 1550 BC). Ayurvedic physicians (5th/6th century BC) first noted the sweet taste of diabetic urine, and called the condition madhumeha ("honey urine"). The term "diabetes" traces back to Demetrius of Apamea (1st century BC). For a long time, the condition was described and treated in traditional Chinese medicine as xiāo kě (消渴; "wasting-thirst"). Physicians of the medieval Islamic world, including Avicenna, have also written on diabetes. Early accounts often referred to diabetes as a disease of the kidneys. In 1674, Thomas Willis suggested that diabetes may be a disease of the blood. Johann Peter Frank is credited with distinguishing diabetes mellitus and diabetes insipidus in 1794.
What dynasties were involved in the diagnosis of diabetes?
The diagnosis and treatment of xiāo kě was expanded significantly through the Sui (581–618) and Tang (618–907) dynasties. Zeng Liyan (545–649) expounded on the diagnosis of modern-day diabetes mellitus through the presence of sugar in the urine ( glycosuria ). This characterization was echoed by other physicians in the centuries that followed. Notably, in Wàitái Mìyào (外臺秘要; "Medical Secrets of an Official") written in 752, Wang Tao ( fl. 8th century AD) included a detailed case report of sweet urine and a summary of diabetology history before the Tang dynasty.
