History of diabetes
The number of people who suffer from diabetes appears to
grow each decade. Today 5% of the world’s population has
this metabolic disorder that affects the control of blood
glucose. Are there really more people developing diabetes
mellitus or are there just more being diagnosed? The
question is difficult to answer.
Diabetes is actually a lifestyle illness that is often
brought on by several factors; genetics, environment and
nutrition all play a role in the condition. But diabetes
isn’t a disease of the 20th century. In fact it was 1552
B.C. when physician Hesy-ra, an Egyptian, first wrote about
polyuria as a symptom.
The history of diabetes dates back to centuries before
Christ and continues to play out even to this day. In the
early days of medicine doctors didn’t have sophisticated
methods of testing people believed to have diabetes so they
employed the help of ‘water tasters’. Up until the 11th
century these tasters would taste the urine of those suspected
to have diabetes to discern if the urine had a sweet taste to
it. When blood sugar increases the glucose (sugar) spills
out into the urine. As a result the word ‘mellitus’
(Latin for honey referring to the sweet taste) was added to the
diagnosis.
It was the early 19th century in the history of diabetes
before scientists were able to develop the first chemical tests
to indicate and measure the presence of glucose in the
urine. This was an important break through in the
diagnosis and treatment of this condition. Now doctors
could more consistently diagnose and monitor this condition
that causes long-term effects on the health of the
sufferer.
Treatment for diabetes wasn’t focused on diet until the
1870’s when French physician Bouchardat noticed that the
glycosuria (glucose in the urine), that was common in his
diabetic patients, decreased significantly during food
rationing. The French were forced to ration food during
siege by Germany during the Franco-Prussian war. After
noticing the difference in the glycosuria Bouchardat theorized
that it was diet that played an important role in the treatment
of diabetes.
Following the end of the war French researcher, Claude
Bernard, studied the function of the pancreas and liver making
important discoveries in the metabolism of glycogen. At
the same time in the history of diabetes Czech researcher,
Pavlov, discovered the link between the nervous system and
secretion of gastric acid. The combination of both
discoveries helped later researchers to understand the
physiology of the digestive system.
History of Diabetes
In 1869 Paul Langerhans, a German medical student, announced
the two systems of cells in the pancreas. But it wasn’t
until 1920 that Dr. Banting conceived the possibility of
insulin and began his quest to discover the chemical using dogs
who were de-pancreatized.
It was 20 years later that the link between high blood
glucose and damage to the kidneys and eyes was discovered and
published paving the way for more standardized insulin
treatment using a standard insulin syringe.
In 1959 physicians recognized the difference between Type 1
and Type 2 diabetes. This recognition also helped to
individualize the treatment of the diabetic and lengthen their
lifespan by decreasing the risk for complications.
With the advent of laser surgery in 1970 researchers were
able to slow the progressive damage to the eye that diabetics
so often suffered. Other researchers began manufacturing
glucometers to test blood samples for glucose at home, as well
as the insulin pump.
Synthetic insulin was introduced in 1983. Until that
time in the history of diabetes the standard insulin supply was
from cows or bovine insulin.
Today insulin pumps are more popular and covered by
insurance companies who are beginning to recognize the cost
savings by paying a bit more now for a more expensive machine
that delivers insulin in much the same way the body produces
it. In this way insurance costs are decreased as the
patient ages as his risk of complications are decreased.
Research is currently being successfully conducted on the
transplantation of pancreatic cells, without the use of immune
suppressants, which supply the Type 1 diabetic with a natural
source of insulin. The diagnosis, treatment and
complications of diabetes has come a long way from when
‘tasters’ were employed to diagnose diabetes through sweet
tasting urine!
