The Discovery Of Insulin

Before the discovery of insulin, diabetes was a feared disease that most certainly led to death. Doctors knew that sugar worsened the condition of diabetic patients and that the most effective treatment was to put the patients on very strict diets where sugar intake was kept to a minimum. At best, this treatment could buy patients a few extra years, but it never saved them. In some cases, the harsh diets even caused patients to die of starvation. During the nineteenth century, observations of patients who died of diabetes often showed that the pancreas was damaged. In 1869, a German medical student, Paul Langerhans, found that within the pancreatic tissue that produces digestive juices there were clusters of cells whose function was unknown. Some of these cells were eventually shown to be the insulin-producing beta cells. Later, in honor of the person who discovered them, the cell clusters were named the islets of Langerhans. In 1889 in Germany, physiologist Oskar Minkowski and physician Joseph von Mering, showed that if the pancreas was removed from a dog, the animal got diabetes. But if the duct through which the pancreatic juices flow to the intestine was ligated - surgically ti Continue reading >>

    Just how accurate is the A1c test?

    This past October my A1c came in at 5.6 - very close to a pre-diabetes level. fasting was 100. 3 years ago
    A1c was 5.5, and fasting has generally been around 104 - 105. The fasting is always take 4 - 5 hours after
    awakening and usually 14 - 15 hours after the last meal.
    Finally decided to get a meter - Freestyle lite as it was highly rated for accuracy. A week into testing now and
    the numbers don't make sense. Either the meter reads way too low or the fasting/A1c from the blood draws
    are misleading.
    I've been an avid runner for some 30 years - BMI is around 21 and always in good shape. 52 years old. I realize
    that even thin, active types can digress to type II, but again the meter numbers, so far, look good. Granted it
    is only a week of testing.
    I'm assuming the higher fasting at the blood draw is due to a long time between awakening and the draw but how
    to explain the A1c being right next to pre-diabetic levels? How accurate is the A1c?
    Here are the numbers i have thus far:

    You are fine and definitely non diabetic. find something else to worry about. Even better don't worry and be happy life is short enough.

    If you are able to eat wheat bread not so friendly to type 2 by the way even though they say it is then your fine. You wait 4 or 5 hrs before your fasting test did I get that right. If so that is not exactly a fasting as the body will then dump in stored glucose as you move around and do things before testing. Overall your numbers look pretty good, jam for me it just totally out the window I would go to 200 and above.
