So before there was insulin people died very fast from diabetes, some people had no choice but to go onto diets that invoked eating only 450 calories a day witch cased some patients to die of starvation.
Unfortunately there was no way to treat diabetes until the discovery of a drug called Insulin.
Insulin is a hormone produced in the pancreas by the islets of Langerhans that regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes.
“Until the 1980s, trains brought piles of pig pancreases to Indianapolis from the surrounding pork farms. Workers unloaded the pinkish blobs into a building next to the railroad tracks that now serves as a parking garage in the shadow of Eli Lilly & Co., the first company to mass-produce insulin. Lilly miraculously turned those organs into a lifesaving medication”. -diabetesforecast
“In 1978, researchers at a burgeoning biotechnology company called Genentech announced that they had introduced a human gene for insulin into a safe strain of E. coli bacteria, which then produced the protein. Genentech partnered with Lilly, which brought engineered human insulin to the market in 1982 under the brand name Humulin, the first recombinant DNA drug product in the world. This biotechnology scheme is now in use worldwide for basic research as well as industrial applications, creating tens of thousands of protein varieties that help scientists to understand the human body and doctors to treat diseases such as cancer, rheumatoid arthritis, and, of course, diabetes”. -diabetesforecast
