Diabetes used to be very rare, but times have changed. Over the last twenty years it has become an epidemic. Type 2 diabetes (adult onset diabetes) has become epidemic, while type 2 (juvenile onset diabetes) still remains relatively rare.
Type 1 diabetes is caused by a condition in which the pancreas completely shuts down and fails to produce any insulin, causing the blood sugar level to spiral upward out of control. The more common diabetes type 2 (90% of all diabetes) occurs when the patient develops a long-term insulin resistance. Insulin resistance causes the pancreas to secrete more insulin (hyperinsulinemia) in an effort to reduce the blood glucose level. Eventually the pancreas (really the beta cells in the pancreas) just get tired and stop producing enough excess insulin. This is called beta cell burnout, or commonly called insulin resistance.
The result is that without enough insulin becoming secreted by the pancreas, blood glucose level raises to a dangerous level. The danger comes from two factors:
- Excess glucose in the blood produces free radicals (oxidative stress).
- Excess glucose is neurotoxic to the brain.
The ancient Greek describe diabetes as a disease that causes the body to melt into sugar water. When tissue cannot utilize glucose, they will metabolize fat for energy, generating byproducts called ketones, which are toxic at high levels and cause further water loss, as the kidneys try to eliminate them.
Type 1 diabetes typically occurs before the age of 45 and usually makes itself apparent quite suddenly, with such symptoms as dramatic weight loss, frequent thirst and urination.
According to The American Diabetes Association, more than 150,000 people die annually from both type 1 and type 2 diabetes and their long-term complications. According to The American Diabetic Association statistics, 90 to 95% of diabetics are type 2.
While the cause of type 1 diabetes is still somewhat mysterious, the cause of type 2 diabetes is so, As noted another name for type 2 diabetes is insulin resistance. Obesity, particularly visceral obesity, and insulin resistance, thus the inability to fully utilize glucose transporting, qualities of insulin are interlinked.
For reasons related to genetics, a substantial portion of the population has the potential when overweight to become sufficiently insulin resistance that increases demands on the pancreas burnout, the beta cells that produce insulin. Insulin resistance appears to be caused at least in part by inheritance, in part by high level of fat in the form of triglycerides. Insulin resistance by its very nature increases the body’s need for insulin, which therefore causes the pancreas to work harder to produce elevated insulin levels, which can indirectly cause high blood pressure and damaged circulatory system.
Fat in the blood feeding the liver causes insulin resistance, which causes elevated serum insulin, which causes the fat cells to build even more abdominal fat, which raises triglycerides in the liver’s blood supply, which causes insulin levels to increase because of increased resistance to insulin. It sounds circular, it is. The fat that is the culprit here is not dietary fat. High levels of triglycerides in the blood, which are in circulation at some level in the blood stream at all times, thus are not so much the result of dietary fat intake, as they are usually due to carbohydrate consumption.
The onset of type 2 diabetes is lower and more stealthy, but even in its earlier stage, the abnormal blood sugar levels, though not sky high, can cause damage to the nerves, blood vessels, heart, eyes, and more. Type 2 diabetes is often called the silent killer, and it is quite frequently discovered through one of its complications, such as hypertension or a defect in vision.
Type 2 diabetes is at the beginning, a less serious disease. Patients do not melt away into sugar water and die in a few month’s time. Type 2 diabetes can, through chronically but less dramatically elevated blood sugar, be much more insidious. It probably causes more heart attacks, strokes, and amputations than serious type 1 diabetes. Type 2 diabetes is a major cause of hypertension, heart disease, blindness, and amputation due to impaired sensation in feet with poor circulation that do not heal when injured.
