How Type 2 Diabetes Is Diagnosed
Jun 17, · In the Middle Ages, people believed that diabetes was a disease of the kidneys, but an English doctor in the late 18th century found that it occurred in Author: Valencia Higuera. Nov 03, · Centuries later, people known as "water tasters" diagnosed diabetes by tasting the urine of people suspected to have it. If urine tasted sweet, .
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. 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.
Insulin, discovered in 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 in Canada, glycemia control — the control of blood glucose sugar levels — still remains an imprecise science.
In the s, 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.
Belgian doctor Jean Pirart, a pioneer in diabetes treatment, discovered the link between good glucose control and the prevention of complications.
Between andDr. Pirart divided more than 4, patients into three groups based on their level of blood sugar control: good, fair, poor. Using reagent tablets as the measurement method, Dr. The s and s marked are a turning point in the treatment of diabetes. Innovations such as blood glucose readers and strips measuring blood glucose sugar levels gave people with diabetes and their doctors some indispensable tools. InAmerican scientists discovered that sugar attaches to red blood cells hemoglobin and that this could be used to determine how well blood glucose had been controlled in the previous two to four months.
This discovery led to the creation of the glycated hemoglobin A1C test. The advent of monitoring tools enabled researchers to create large-scale studies. Their findings changed the way diabetes was treated. Then two important studies, the Diabetes Control and Complications Trial from to and the United Kingdom Prospective Diabetes Study from toshowed, for both types of diabetes, that maintaining blood glucose sugar levels close to normal values delays and slows the onset of chronic complications from diabetes.
Intensive insulin therapy — multiple injections of insulin mimicking the normal functioning of the pancreas — appeared in the treatment of type 1 diabetes, and now is an increasingly popular treatment option for type 2 diabetes. He weighed just 65 pounds 30 kg and his life hung by a thread. His diabetes had been diagnosed two whats a normal hcg level earlier.
The doctors gave him only weeks to live. For several months, two researchers, Dr. Frederick Banting and Charles Best, what is mup.
sys driver the direction of Dr. John Macleod, had been searching for the mysterious substance that plays the key role in diabetes. They had succeeded in isolating a substance from a dog pancreas and injecting it into other dogs whose pancreas had been removed. They had learned that these diabetic dogs could be saved by this substance. However, the results were highly variable because the researchers had not been able to sufficiently purify the insulin and had been injecting a mixture of insulin and other substances.
A young chemist by the name of James Collip subsequently joined the group. His goal: to obtain pure insulin. Without him, the team would never have obtained positive results as quickly. While Banting and Best continued their research on dogs, Collip used beef pancreases to refine his insulin-extraction technique and, very quickly, decided to use different concentrations of alcohol.
On January 11,the first injection was given to young Leonard Thomson. Tests were done the next day: his blood glucose had fallen from The first injection was a partial failure because the injected insulin was not pure enough. Twelve days after the first injection, after repeatedly testing his insulin, Collip felt ready to repeat the injections on Thomson. This time, they were a success. For the next two days, Thomson did not get an injection and his blood glucose rose.
In the weeks that followed, he got daily injections. He gained weight and strength. Researchers knew that they had made a great discovery. By Februarysix other diabetics had been given the extract with the same positive results.
They called the extract isletin. It was not until April that it was given its final name: insulin. Niny six years later, millions of people are alive thanks to one of the greatest discoveries of the 20th century. History of diabetes More topics. Treating Diabetes: to the Present Day. Before the discovery of insulin, a diagnosis of diabetes meant certain death.

Jan 01, · In the 17th century a London physician, Dr. Thomas Willis, determined whether his patients had diabetes or not by sampling their urine. If it had a sweet taste he would diagnose them with diabetes mellitus- “honeyed” diabetes. This method of monitoring blood sugars went largely unchanged until the 20th century. In the late 18th century, however, an English physician noticed that diabetes developed in individuals after an injury to the pancreas. At about the same time, another English physician identified sugar in the urine of patients with diabetes. By the 19th century, sugar in the urine . Jan 15, · Johann Peter Frank is credited as being the first physician to distinguish clinical differences between diabetes mellitus and diabetes insipidus. Early 19 th Century By the early 19th Century, chemical tests have been devised which can detect excess sugar in the urine.
For 2, years diabetes has been recognized as a devastating and deadly disease. In the first century A. Life lasts only for a time, but not very long. For they urinate with pain and painful is the emaciation. For no essential part of the drink is absorbed by the body while great masses of the flesh are liquefied into urine. Aretaeus recommended oil of roses, dates, raw quinces, and gruel.
Thomas Willis, determined whether his patients had diabetes or not by sampling their urine. This method of monitoring blood sugars went largely unchanged until the 20th century. In the early 20th century, diabetologists such as Dr. Frederick Allen prescribed low calorie diets-as little as calories per day for his patients. His diet prolonged the life of people with diabetes but kept them weak and suffering from near starvation. In effect, the most a person afflicted with diabetes could do was blindly offer himself to the medical establishment and pray for a cure.
A restless drowsiness shaded into semi-consciousness. As the lungs heaved desperately to expel carbonic acid as carbon dioxide , the dying diabetic took huge gasps of air to try to increase his capacity.
At that point the family could make its arrangements with the undertaker, for within a few hours death would end the suffering. A young surgeon Frederick Banting, and his assistant Charles Best, kept a severely diabetic dog alive for 70 days by injecting it with a murky concoction of canine pancreas extract.
With the help of Dr. Collip and Dr. Macleod, Banting and Best administered a more refined extract of insulin to Leonard Thompson, a young boy dying of diabetes. Until the discovery of insulin, most children diagnosed with diabetes were expected to live less than a year.
News of the miracle extract, insulin, spread like wildfire across the world. By differentiating between the two types of diabetes, Hinsworth helped open up new avenues of treatment. Starting in the late s, new types of pork and beef insulin were created to better manage diabetes. PZI, a longer acting insulin, was created in In NPH insulin was marketed, and in Lente, containing high levels of zinc which promotes a longer duration of action was invented. In the s, oral medications-sulfonylureas were developed for people with type II.
These drugs stimulate the pancreas to produce more insulin, helping people with type II diabetes keep tighter control over their blood sugars. In the s urine strips were developed. Becton-Dickinson introduced the single use syringe in This greatly reduced the amount of pain from injections as well as the time-consuming ritual of boiling needles and glass syringes. Diabetes Health board member Dr. They often became dull and developed barbs on the end. And in order to sterilize them they had to be boiled for twenty minutes.
Bernstein describes one particularly bizarre incident he experienced while carrying his Ames Eyetone Meter. I was carrying my meter in a bag, and I hung it up in the coat room. A few minutes later everyone was in a panic, saying a bomb had been found in the coat room. The entire 24 story building was being evacuated. It took me some time to convince the bomb squad not to blow up my meter. Thankfully, the days of hefting around a three pound glucose meter are over.
The pump dispenses a continuous insulin dosage through a cannula plastic tube , using a small needle that is inserted into the skin. The first pumps, created in , were large and bulky and had to be carried in a backpack. The pumps of today are light and compact and can easily be carried in a pocket or clipped to a belt.
In Derata released the first needle-free insulin delivery system-the Derma-Ject. The Derma-Ject carried the insulin on the side and had no pressure adjustment feature. One early user of the Derma-Ject decided not to use it after a month because it gave him such a terrible jolt every time he used it. Thankfully, modern needle-free injectors have adjustable pressure, so they are relatively pain free. The hemoglobin A1c test was devised in in order to create a more precise blood sugar measurement.
With the A1c, hemoglobin, the oxygen-carrying pigment in red blood cells, is used to track glucose changes over a period of four months, the life span of the cell. Hemoglobin links with the glucose in blood; the more glucose present, the greater amount of hemoglobin linked with glucose. With the conclusion of the DCCT in , studies showed that people who were able to keep their blood glucose levels as close to normal as possible had less chance of developing complications, such as eye, kidney and nerve disease.
Before this, many doctors had not put much emphasis on tight control of blood glucose levels. The common belief for decades was that diligent monitoring of blood sugars and intensive insulin therapy had little consequence for people with diabetes.
Unlike sulfonylurea drugs, which stimulate insulin release, Metformin does not increase insulin production. Since Metformin promotes weight loss, decreases hyperglycemia, and improves lipid levels, it has been shown to be an effective tool for people with type II diabetes when used in conjunction with sulfonylureas.
Precose, an oral medication, was approved for use by people with type II diabetes in September Precose delays the digestion of carbohydrates, thereby reducing the sudden rise in blood glucose after eating a meal.
Precose can be used in conjunction with diet to lower blood sugars in people with type II whose glucose levels cannot be regulated through diet alone. Lispro, a new fast-acting insulin, was released in August of by Eli Lilly under the brand name Humalog. The Future of Diabetes? It was from this wealth of knowledge that the discovery of insulin emerged in a small laboratory in Canada.
Since insulin saved the life of young Leonard Thompson 75 years ago, medical innovations have continued to make life easier for people with diabetes.
As the 21st century rapidly approaches, diabetes researchers continue to pave the road toward a cure. Today, it is unclear what shape the road will take; perhaps another dramatic discovery like insulin waits around the corner, or possibly researchers will have to be content with the slow grind of progress.
