There’s a ton of information out there about diabetes — after a diagnosis, finding information can seem overwhelming. But knowledge is power, and the information presented here could be lifesaving. This information in this article originally appeared in Medical News Today and offers basic information about what diabetes is, how it affects its victims, and what you can do if you have it.

Diabetes (diabetes mellitus) is classed as a metabolism disorder. Metabolism refers to the way our bodies use digested food for energy and growth. Most of what we eat is broken down into glucose. Glucose is a form of sugar in the blood — it is the principal source of fuel for our bodies.

When our food is digested the glucose makes its way into our bloodstream. Our cells use the glucose for energy and growth. However, glucose cannot enter our cells without insulin being present – insulin makes it possible for our cells to take in the glucose.

Insulin is a hormone that is produced by the pancreas. After eating, the pancreas automatically releases an adequate quantity of insulin to move the glucose present in our blood into the cells, and lowers the blood sugar level.

A person with diabetes has a condition in which the quantity of glucose in the blood is too elevated (hyperglycemia). This is because the body either does not produce enough insulin, produces no insulin, or has cells that do not respond properly to the insulin the pancreas produces. This results in too much glucose building up in the blood. This excess blood glucose eventually passes out of the body in urine. So, even though the blood has plenty of glucose, the cells are not getting it for their essential energy and growth requirements.

There are three main types of diabetes:

Diabetes Type 1 – You produce no insulin at all.
Diabetes Type 2 – You don’t produce enough insulin, or your insulin is not working properly.
Gestational Diabetes – You develop diabetes just during your pregnancy.
(World Health Organization)

Diabetes Types 1 and 2 are chronic medical conditions – this means that they are persistent and perpetual. Gestational Diabetes usually resolves itself after the birth of the child.

Treatment is effective and important

All types of diabetes are treatable, however Type 1 and Type 2 diabetes last a lifetime; there is no known cure. The patient receives regular insulin, which became medically available in 1921. The treatment for a patient with Type 1 is mainly injected insulin, plus some dietary and exercise adherence.

Patients with Type 2 diabetes are usually treated with tablets, exercise and a special diet, but sometimes insulin injections are also required.

If diabetes is not adequately controlled the patient has a significantly higher risk of developing complications, such as hypoglycemia, ketoacidosis, and nonketotic hypersosmolar coma. Longer term complications could be cardiovascular disease, retinal damage, chronic kidney failure, nerve damage, poor healing of wounds, gangrene on the feet which may lead to amputation, and erectile dysfunction.

U.S. Diabetes Statistics from the American Diabetes Association as of 2007:

17.9m people are diagnosed with diabetes
5.7m people are undiagnosed with diabetes
57m people have pre-diabetes
186,300 (0.22%) people under 20 have diabetes
1 in every 400 to 600 under 20-year olds have Type 1 diabetes
2m adolescents have pre-diabetes
23.5m (10.7%) of those over 20 have diabetes
12.2m of those over 60 have diabetes
12m men (11.2%) have diabetes
11.5m women (10.2%) have diabetes
