Diabetes can strike anyone, from any walk of life.

And it does in numbers that are dramatically increasing. In the last decade, the cases of people living with diabetes jumped almost 50 percent to more than 30 million Americans. Worldwide, it afflicts more than 422 million people.

Diabetes is a leading cause of blindness, kidney failure, amputations, heart failure and stroke.

Living with diabetes places an enormous emotional, physical and financial burden on the entire family. Annually, diabetes costs the American public more than $245 billion.

Just what is diabetes?

To answer that, you first need to understand the role of insulin in your body. When you eat, your body turns food into sugars, or glucose. At that point, your pancreas is supposed to release insulin. Insulin serves as a key to open your cells, to allow the glucose to enter -- and allow you to use the glucose for energy.

But with diabetes, this system does not work.

Several major things can go wrong causing the onset of diabetes. Type 1 and type 2 diabetes are the most common forms of the disease, but there are also other kinds, such as gestational diabetes, which occurs during pregnancy, as well as other forms.

The more severe form of diabetes is type 1, or insulin-dependent diabetes. Its sometimes called juvenile diabetes, because type 1 diabetes usually develops in children and teenagers, though it can develop at any age.

With type 1 diabetes, the bodys immune system attacks part of its own pancreas. Scientists are not sure why. But the immune system mistakenly sees the insulin-producing cells in the pancreas as foreign, and destroys them. This attack is known as "autoimmune" disease.

These cells called islets (pronounced EYE-lets) are the ones that sense glucose in the blood and, in response, produce the necessary amount of insulin to normalize blood sugars.

Insulin serves as a key to open your cells, to allow the glucose to enter -- and allow you to use the glucose for energy. Without insulin, there is no key. So, the sugar stays -- and builds up-- in the blood. The result: the bodys cells starve from the lack of glucose. And, if left untreated, the high level of blood sugar can damage eyes, kidneys, nerves, and the heart, and can also lead to coma and death.

So, a person with type 1 treats the disease by taking insulin injections. This outside source of insulin now serves as the key -- bringing glucose to the bodys cells.

The challenge with this treatment is that its often not possible to know precisely how much insulin to take. The amount is based on many factors, including:

Food

Exercise

Stress

Emotions and general health

These factors fluctuate greatly throughout every day. So, deciding on what dose of insulin to take is a complicated balancing act.

If you take too much, then your body burns too much glucose -- and your blood sugar can drop to a dangerously low level. This is a condition called hypoglycemia, which, if untreated, can be potentially life-threatening.

If you take too little insulin, your body can again be starved of the energy it needs, and your blood sugar can rise to a dangerously high level -- a condition called hyperglycemia. This also increases the chance of long-term complications.

The most common form of diabetes is called type 2, or non-insulin dependent diabetes.

This is also called adult onset diabetes, since it typically develops after age 35. However, a growing number of younger people are now developing type 2 diabetes.

People with type 2 are able to produce some of their own insulin. Often, its not enough. And sometimes, the insulin will try to serve as the key to open the bodys cells, to allow the glucose to enter. But the key wont work. The cells wont open. This is called insulin resistance.

Often, type 2 is tied to people who are overweight, with a sedentary lifestyle.

Treatment focuses on diet and exercise. If blood sugar levels are still high, oral medications are used to help the body use its own insulin more efficiently. In some cases, insulin injections are necessary.
