What is Type 2 Diabetes? • Diabetes is the impairment of the body to make food into energy. • More frequent in older adults. • 90 to 95 % of cases are type 2, most common form. • After eating, the body breaks food into glucose (sugar). • Glucose is a fuel source for cells. • In diabetes, the body doesn’t produce enough insulin or cells don’t respond to insulin correctly. • Insulin is a hormone that adjusts glucose levels in blood. • Result in high blood glucose levels.
History • Diabetes has been recognized for thousands of years. • Noted as “Sugar Urine Disease.” • Medhumeha was discovered by an Indian physician and said that exercise could cure it. • Manuscript noted “passing of too much urine.” • The description and name of diabetes was from a Greek physician Aretaeus of Cappadocia. • Hippocrates never mentioned it. • Thought it may have been incurable, “death sentence.” • Aretaeus tried to treat diabetes. • Noted that life would be short, painful, and disgusting with diabetes. • No treatment of type 2 diabetes historically.
History • The different types of diabetes were discovered in the twentieth century. • 1921 – Insulin was discovered. • 1935 – Roger Hinsworth discovered the types of diabetes. • Type 1 diabetes and type 2 diabetes • Type 2 diabetes is known as the non-insulin- dependent diabetes mellitus. • Adult-onset diabetes • Maturity-onset diabetes • Most often in middle aged adults but a rising amount of children are being diagnosed.
