Diabetes Mellitus – Types, Causes, Symptoms and Complications
Article by Peter hutch
Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels, which result from defects in insulin secretion, or action, or both. Diabetes mellitus, commonly referred to as diabetes (as it will be in this article) was first identified as a disease associated with “sweet urine,” and excessive muscle loss in the ancient world.
Diabetes is a serious, lifelong condition that affects an estimated 20.8 million people. About 30 percent (6.2 million) do not know they have it. Each year, about 1.5 million people find out they have diabetes (1) and probably have had the disease for seven years before it was diagnosed.
Diabetes is a metabolic disorder affecting the way the body uses digested food for growth and energy. As a person eats, digestive juices break down the food into a simple sugar called glucose. Glucose is the main source of fuel for the body.
Types of Diabetes Mellitus:
Type 1 diabetes mellitus can occur at any age and is characterized by the marked and progressive inability of the pancreas to secrete insulin because of autoimmune destruction of the beta cells. It commonly occurs in children, with a fairly abrupt onset; however, newer antibody tests have allowed for the identification of more people with the new-onset adult form of type 1 diabetes mellitus called latent autoimmune diabetes of the adult (LADA).
Symptoms of type 1 diabetes:
• Increased thirst• Increased urination• Weight loss in spite of increased appetite
Type 2 diabetes mellitus was once called adult-onset diabetes. Now, because of the epidemic of obesity and inactivity in children, type 2 diabetes mellitus is occurring at younger and younger ages. Although type 2 diabetes mellitus typically affects individuals older than 40 years, it has been diagnosed in children as young as 2 years of age who have a family history of diabetes.
Symptoms of type 2 diabetes:
• Blurred vision • Slow-healing infections • Impotence in men
