Definition of Diabetes Mellitus l Diabetes mellitus is a chronic disease caused by inherited and/or acquired deficiency in production of insulin by the pancreas, or by the ineffectiveness of the insulin produced. l Such a deficiency results in increased concentrations of glucose in the blood, which in turn damage many of the body’s systems, in particular the blood vessels and nerves. (World Health Organization, April 2002)

Type 1. (Juvenile-onset diabetes or IDDM) l Type 1 diabetes is usually diagnosed in children and young adults, and was previously known as juvenile diabetes. In type 1 diabetes, the body does not produce insulin. Insulin is a hormone that is needed to convert sugar (glucose), starches and other food into energy needed for daily life. l Metabolic condition in which the beta cells of pancreas no longer produce insulin; characterized by hyperglycemia, breakdown of body fats and protein and development of ketosis

Blood Sugar l Fasting glucose test a check of a person's blood glucose level after the person has not eaten for 8 to 12 hours (usually overnight). This test is used to diagnose pre-diabetes and diabetes. l Oral glucose tolerance test In the oral glucose tolerance test the patient, after fasting for 15 hours, drinks 75 g of glucose in 300 ml of water, over 5 minutes. Blood glucose is measured before the drink and after 30, 60, 90 and 120 minutes. Urine is collected before the drink, and after 60 and 120 minutes. Before the test, for a period of 6 hours, the patient should avoid smoking and drinking coffee l 2 h Postprandial method: Levels <140 mg/d. L are considered to reflect normal glucose metabolism. A result between 140 -199 mg/d. L indicates impaired glucose tolerance. A result of >=200 mg/d. L is provisional evidence of glucose intolerance.

Insulin 1. 2. 3. Insulin is a hormone released from the beta cells of the pancreas. Insulin's most important function is to facilitate glucose (blood sugar) uptake by a variety of tissues, especially adipose (fat) and skeletal muscle. Insulin also stimulates the synthesis and storage of triglycerides and proteins. Insulin is the most important regulator of blood glucose. High blood glucose (such as exists shortly after a meal) stimulates the release of insulin, whereas low blood glucose levels inhibit insulin release. Normal value: 5 -20 mc. U/m. L while fasting

Types of Insulin l l Rapid-acting insulin, such as insulin Lispro (Eli Lilly), insulin Aspart (Novo Nordisk), or insulin Glulisine (sanofi-aventis), begins to work about 5 minutes after injection, peaks in about 1 hour, and continues to work for 2 to 4 hours. Regular or Short-acting insulin (human) usually reaches the bloodstream within 30 minutes after injection, peaks anywhere from 2 to 3 hours after injection, and is effective for approximately 3 to 6 hours. Intermediate-acting insulin (human) generally reaches the bloodstream about 2 to 4 hours after injection, peaks 4 to 12 hours later, and is effective for about 12 to 18 hours. Long-acting insulin (ultralente) reaches the bloodstream 6 to 10 hours after injection and is usually effective for 20 to 24 hours. There also two long-acting insulin analogues: glargine and detemir. They both tend to lower glucose levels fairly evenly over a 24 -hour period with less of a peak of action than ultralente.
Type 2. Diabetes mellitus (NIDDM) l l Type 2 diabetes is the most common form of diabetes. In type 2 diabetes, either the body does not produce enough insulin or the cells ignore the insulin. Insulin is necessary for the body to be able to use glucose for energy. When you eat food, the body breaks down all of the sugars and starches into glucose, which is the basic fuel for the cells in the body. Insulin takes the sugar from the blood into the cells. l When glucose builds up in the blood instead of going into cells, it can cause two problems: 1)Right away, your cells may be starved for energy. 2)Over time, high blood glucose levels may hurt your eyes, kidneys, nerves or heart. l Condition of fasting hyperglycemia occurring despite availability of body’s own insulin
