Narrator: Have you ever ever thought of how your physique turns meals into power or simply how fastidiously it has to handle that course of?
Once we eat, the glucose from our meals will get saved within the liver as glycogen.

And primarily based on our physique’s wants, the liver will convert that glycogen again into glucose, in order that it could possibly journey by means of the blood and get to our cells, which flip that glucose into power.
In the meantime our pancreas produces a hormone known as insulin, whose job is to enter the blood and inform our cells to soak up that glucose.
That additionally makes insulin a regulator of our physique’s blood sugar ranges, stopping the issues that may occur when our ranges are too excessive or too low.
When the pancreas stops producing insulin, glucose doesn’t enter our cells. As a substitute it accumulates within the bloodstream.
In some individuals, the pancreas stops making insulin altogether.
This situation is named Sort 1 Diabetes.
Sort 1 Diabetes is typically known as juvenile diabetes as a result of it typically makes its look in childhood or adolescence.
Whereas the precise trigger is mysterious, we all know the illness occurs as a result of immune cells goal and assault insulin-producing cells within the pancreas known as beta cells.
As these cells get destroyed, the physique stops producing insulin and loses that key regulator of blood sugar ranges.
That in flip can drive various signs, together with fatigue and weak point.
Rising blood glucose ranges trigger the physique to search for different methods to eliminate extra sugar, like frequent urination.
That in flip requires the physique to attract water from different locations, such because the pores and skin and eyes, resulting in dry mouth and pores and skin and in addition imaginative and prescient adjustments.
Individuals might also really feel very thirsty as their physique alerts the necessity for extra water.
Excessive blood sugar ranges may also trigger poor blood stream, making it troublesome for the physique to heal sores and different wounds.
And a few individuals might also expertise a kind of nerve injury generally known as diabetic neuropathy, which may result in numbness or ache in areas such because the chest or arms.
Our understanding of diabetes goes again millennia.
Historic information from India and China documented some type of situation with a really curious symptom: pee that tasted candy.
Varied texts included different signs as effectively, resembling extreme thirst and speedy weight reduction.
One of many earliest references to the time period “diabetes” dates to the second century C.E., when the Greek doctor Aretaeus famous the time period and stated it drew from the Greek phrase diabaino.
It means “I move by means of,” in reference to the extreme urine.
In his writing, he famous that whereas it may take a very long time for the situation to kind, individuals died shortly as soon as it had established itself.
As therapy, he urged consuming cereals, milk and wine.
Regardless of these early observations of diabetes, it will take a very long time for medical doctors and scientists to know the situation effectively sufficient to make it much less deadly.
Within the seventeenth century the English doctor Thomas Willis expanded the title to “diabetes mellitus.”
The addition of “mellitus” drew on the Latin phrase mel, for honey, to as soon as once more emphasize the candy style of urine that was related to diabetes.
And in 1776 a doctor named Matthew Dobson traced that sweetness to the presence of sugar within the urine.
Over the subsequent few centuries, scientists would uncover the organs and molecules that led to that extra sugar.
Within the nineteenth century Claude Bernard uncovered the significance of the liver in regulating blood sugar ranges.
A number of many years later Joseph von Mering and Oskar Minkowski found that eradicating the pancreas from a canine led to the event of diabetes.
Shortly after that, Edward Albert Sharpey-Schafer hypothesized that diabetes was the results of a deficiency in a single chemical made in a area of the pancreas known as the islets of Langerhans.
He known as this chemical insulin, counting on the Latin phrase “insula” for island to present credit score to these islet cells.
However the precise discovery of insulin was the work of Frederick Banting and Charles Greatest, who, in 1921, discovered that they may reverse diabetes in canines by introducing pancreatic cells from wholesome canines.
They’d later work with James Collip and John Macleod to purify insulin from cow pancreases, and in 1922 a 14 12 months previous boy named Leonard Thompson obtained one of many first insulin injections to deal with diabetes.
He would go on to reside 13 years earlier than dying of pneumonia.
Over the twentieth and twenty first centuries, scientists have developed applied sciences which have made kind 1 diabetes treatable.
These embody meters to verify blood glucose ranges and pumps that give small doses of insulin.
And with advances in development and software program, these instruments have develop into smaller and extra transportable.
Regardless of these advances, scientists are nonetheless pursuing a treatment for kind 1 diabetes.
The historical past of kind 1 diabetes reveals how we’ve got managed to take a illness that was as soon as deadly and make it treatable.
And as scientists make extra advances, their work displays the hope and risk that someday, this illness will develop into curable.
