Diabetes

What is diabetes?

Diabetes is a metabolic disorder characterized by a failure to secrete enough insulin, or, in some cases, the cells do not respond appropriately to the insulin that is produced. Because insulin is needed by the body to convert glucose into energy, these failures result in abnormally high levels of glucose accumulating in the blood. Diabetes may be a result of other conditions such as genetic syndromes, chemicals, drugs, malnutrition, infections, viruses, or other illnesses.

The three main types of diabetes - type 1, type 2, and gestational - are all defined as metabolic disorders that affect the way the body metabolizes, or uses, digested food to make glucose, the main source of fuel for the body.

What is prediabetes?

In prediabetes, blood glucose levels are higher than normal but not high enough to be defined as diabetes. However, many people with prediabetes develop type 2 diabetes within 10 years, states the National Institute of Diabetes and Digestive and Kidney Diseases. Prediabetes also increases the risk of heart disease and stroke. With modest weight loss and moderate physical activity, people with prediabetes can delay or prevent type 2 diabetes.

How does diabetes affect blood glucose?

For glucose to be able to move into the cells of the body, the hormone insulin must be present. Insulin is produced primarily in the pancreas, and, normally, is readily available to move glucose into the cells.

However, in persons with diabetes, either the pancreas produces too little or no insulin, or the cells do not respond to the insulin that is produced. This causes a build-up of glucose in the blood, which passes into the urine where it is eventually eliminated, leaving the body without its main source of fuel.

Complications of diabetes:

Diabetes is the sixth leading cause of death among Americans, and the fifth leading cause of death from disease. Although it is believed that diabetes is under-reported as a condition leading to or causing death, each year, more than 200,000 deaths are reported as being caused by diabetes or its complications. Complications of diabetes include eye problems and blindness, heart disease, stroke, neurological problems, amputation, and impotence.

Because diabetes (with the exception of gestational diabetes) is a chronic, incurable disease that affects nearly every part of the body, contributes to other serious diseases, and can be life threatening, it must be managed under the care of a physician throughout a person's life.
