German doctors worked with domestic dogs in 1922 to learn more about diabetes mellitus. They would remove a small gland located directly under the stomach called the pancreas. After removing this gland, all dogs showed all the symptoms of diabetes. They died shortly after. Many dog ​​shelters and labs had them all peeing in the corners of the labs. On summer days they left the windows open, which let in insects like ants. Since they are attracted to sugar, many of them clustered around the dogs' urine in the lab. Although it was an accidental discovery, diabetes was now tested for through urine, and because doctors removed dogs' pancreases and their pee was very sweet, blood sugar control was linked to the pancreas. In short, diabetes stops the pancreas from working. For people with diabetes mellitus, 1921 was a very important year. It was the year that Canadian physician Frederick Banting and his assistant Charles H. Best discovered a special hormone in the dog's pancreas. This hormone is called insulin. On July 30, 1921, they tested this hormone on dogs and noticed a significant decrease in their blood sugar levels. Thanks to JJR Macleod, Banting and Best, for purified insulin. After a year, it helped many people, including a little boy with severe diabetes. Both Banting and Best shared the Nobel Prize in Physiology and Medicine. They became the “discoverers” of insulin and changed the lives of people with diabetes mellitus. In the Britannica article on the pharmaceutical industry, it is stated that insulin was discovered well before 1921. In 1869, it is written that Paul Langerhans, a medical student from Germany, was in the middle of the paper ......complications, but there are a few. Type 2 can be very stressful because if you don't slow down the work of your pancreas, you could get type 1. You need to lose weight if you want this to happen and with that in mind, you need to work very hard. Also pills can be boring, some people take 1, others take 4 or more. Having to take pills every morning knowing that you will never get rid of diabetes is stressful and scary. Diabetes has been around forever, with innovations, incredible discoveries, and just plain dumb luck. Scientists, by chance, discover how to diagnose people with diabetes, discover the symptoms that accompany the disease. it can be difficult, stressful and boring. In the 1960s, insulin needles were made of glass, so it was painful to insert them because they were between ¾ and 1 inch long. We now have plastic needles, pumps and pens that make diabetes treatment much easier..
