First chemical tests to measure the presence of glucose in the urine are developed
A german medical student, Langerhans, discovers the the pancreas is responsible for secreting two times of cells, one of them being the hormone Insulin.
Scientist Von Mering disproved the theory that removing the pancreas caused Diabetes.
Zuelzer extracts insulin from the Pancreas and injects it into five patients with diabetes. Glucose in the urine is reduced by the treatment but there were many negative side effects.
Benedict creates a new method, Benedict's Solution, to more effectively measure the amount of glucose in urine.
Allen's book, "Studies Concerning Glycosuria and Diabetes" introduces a change in diabetes therapy from this point in time
Took place in 1921 in Canada by Fredrick Banting, an unsuccessful orthopaedic surgeon, who after reading about the association between the pancreas and diabetes became convinced that he could find the antidiabetic substance.
On January 11, 1922, a 14-year-old boy became the first human patient to receive insulin made by Banting and Best.
Eli Lilly begins commercial production of insulin.
Home testing for sugar in urine is introduced. This simple color reactivity test allowed for closer monitoring of diabetes at home.
1936, protamine zinc insulin was introduced. This was longer lasting and allowed for more flexibility.
Helen Free develops the "dip-and-read" urine test, allowing instant monitoring of blood glucose levels
Oral drugs that help lower blood glucose levels are introduced
First insulin pump developed
First blood glucose meter (Ames) is introduced for use in doctors' offices
The at-home insulin pen system is introduced
Instant glucose tablets are introduced to increase blood glucose levels with ease
The FDA approves the first recombinant DNA human insulin. Called Humalog.
Life expectancy for people with diabetes in 2004 is still 15 years lower than that of the general population.
