I don't have any questions, I just wanted to thank you for bringing life back to me.

I was so sick and now I am feeling as good as I did twenty years ago! It has been a long battle: no energy, aches and pains going from one Dr. to the next. They told me it was anything from arthritis to depression; they had me on steroids for three years... All behind me now!

I just don't know how to thank you. I think it would be wonderful if you could just be everywhere with your caring heart. Information and the real reason behind all of the bad, sick days that so many of us have had.

Sincerely, Jessica...@telusplanet.net

Diabetes

Of the 15 million Americans who have Type II diabetes, more than a third are unaware of it.
 Another 21 million Americans have a greater than 50/50 chance of developing the disease because they have impaired blood-sugar metabolism. This year alone more than 187,000 people will die of Type II diabetes, also called non-insulin-dependent diabetes mellitus (NIDDM), making it the sixth leading cause of death by disease. Each day, over 2,200 people are diagnosed with this chronic life debilitating, expansive, and pro-aging disease.

What is Diabetes?

Glucose is a simple sugar found in food. It is an essential nutrient that provides energy for the proper functioning of the body cells. After meals, food is digested in the stomach and the intestines into glucose and other nutrients. The glucose in digested food is absorbed by the intestinal cells  into the bloodstream, and is carried by blood to all the cells in the body. However, glucose cannot enter the cells alone. It needs assistance from insulin in order to penetrate the cell walls. Insulin therefore acts as a regulator of glucose metabolism in the body.

Insulin is called the "hunger hormone".  As the blood sugar level increases following a carbohydrate rich meal, the corresponding insulin level rises with the eventual lowering of the blood sugar level and glucose is transported from the blood into the cell for energy.  When the blood glucose levels are lowered, the insulin release from the pancreas is turned off. When the blood sugar level drops below a certain level, hunger is felt. This often occurs a few hours after the meal. In normal individuals, such a regulatory system helps to keep blood glucose levels in a tightly controlled range. Cravings for sweets frequently form part of this cycle, which can lead to snacking, often for more carbohydrates. If the cravings are not fulfilled, sensations such as hunger, dizziness, moodiness, and a state of "collapse" can result.

This system of auto regulation and homeostasis is the function of the pancreas and it works around the clock. Dysfunction of this auto regulation system - either inability of the pancreas to secrete any or insufficient insulin, or pancreas overload from too much sugar ingested over a long period of time, or over compensatory mechanism, or a combination of these, results in the lack of insulin, and hence high blood sugar. This is the hallmark of diabetes mellitus (commonly called diabetes)
