Adrenal glands -  Glands located at the top of each kidney that secrete important hormones for the function of many organ systems in the body.
Adrenaline -  One of the secretions of the adrenal glands. It helps the liver release glucose (sugar) and limit the release of insulin. It also makes the heart beat faster and can raise blood pressure.
Alpha Cells -  Alpha cells are found in the pancreas. They produce a hormone called glucagon, which raises blood glucose levels.
Antibodies -  Proteins that the body makes to protect itself from foreign substances.
Antibody -  A special kind of protein made by the immune system that is released in response to something foreign in the body eg. virus. Antibodies help fight infection.
Autoimmunity -  Pertaining to development of an immune response to one's own tissue.
Basal Bolus Injections -  Insulin injections four times a day.
Beta Cells -  Cells in the pancreas that make the hormone insulin.
Biopsy -  Removal of a small amount of tissue or fluid from the body, examined under a microscope to determine whether disease is present.
Blood Glucose Level (BGL) -  The amount of glucose (sugar) in the blood stream.
Blood Glucose Meter -  A device used to measure blood glucose levels.
Bovine (beef) insulin -  Insulin extracted from the pancreas of cattle. Has been replaced by human insulin.
Cannula -  A small tube that is inserted into the body to assist in various methods of insulin delivery eg. pumps, insuflon.

Diabetes Educator -  A health professional who specialises in providing education about the management of diabetes.
Diabetic ketoacidosis (DKA) -  A sudden loss of control of type 1 diabetes with high blood glucose levels and breakdown of fat leading to a build up of acids in the blood with nausea, vomiting and dehydration. Without urgent medical attention, DKA can lead to coma and death.
Endocrinologist -  A doctor who specialises in the management of diseases of the glands, including the adrenal, thyroid, pituitary, parathyroid glands, ovaries, testicles and pancreas.
Enzymes -  A special protein made in the body that assists with naturally occurring biological functions of the body.
Erectile Dysfunction (Impotence) -  The loss of a man’s ability to have an erection. Some men may become impotent after having diabetes for a long time because the nerves or blood vessels have become damaged. Sometimes the problem has nothing to do with diabetes and may be treated with counselling.
Fats -  One of the three main classes of foods and a source of energy in the body. Fats help the body use some vitamins and keep the skin healthy. They also serve as energy stores for the body. In food, there are three types of fats: saturated, polyunsaturated and monounsaturated.
Fibre -  A substance found in foods that come from plants. Fibre helps in the digestive process and is thought to lower cholesterol and help control blood glucose (sugar). The two types of fibre in food are soluble and insoluble.
Fit -  A convulsion or seizure that can be a symptom of severe or untreated hypoglycaemia.
Gastroparesis -  A complication of diabetes that causes delayed digestion resulting in unpredictable swings in blood glucose levels

Glucose
The body’s main source of energy.
Glucagon -  A hormone made by the pancreas that causes the liver to release glucose from body stores. Manufactured glucagon is injected to raise blood glucose levels in a person with severe hypoglycaemia.
Glycaemic Index -  A ranking of carbohydrate foods according to their effect on blood glucose levels.

Glycemic Response
The effect of different foods on blood glucose (sugar) levels over a period of time.
Glycemic Load -  The predicted effect of a food on blood glucose levels that takes into account glycemic index and total available carbohydrate.
Glycogen -  The body’s stores of glucose in the liver and muscle which release glucose (sugar) into the blood when needed by cells. Glycogen is the chief source of stored fuel in the body.
HbA1c -  A test to identify the average blood glucose level over the last 2-3 months. Also known as glycosylated haemoglobin, this test measures the amount of glucose that attaches to red blood cells which depends on how much glucose is in the bloodstream. If BGLs have been high over the 2-3 month period, more glucose will attach to the red blood cells and HbA1c will be high. If BGLs are mostly within the recommended range, then HbA1c will be closer to the desired level.
Honeymoon Period -  A remission phase after the diagnosis of type 1 diabetes when there is partial, temporary recovery of insulin production by the pancreas. The amount of injected insulin required to manage diabetes is significantly reduced. The honeymoon period may last a few months to a year.
Hormone -  Hormones are chemicals released by special cells that tell other cells what to do. For instance, insulin is a hormone made by the beta cells in the pancreas. When released, insulin tells other cells to use glucose (sugar) for energy.
Human Insulin -  Insulin that has been manufactured to be identical to that produced naturally in the human pancreas.
Hyperglycaemia -  Blood glucose levels higher than the desirable range.
Hyperlipidemia -  Too high a level of fats (lipids) in the blood.
Hypoglycaemia -  Blood glucose levels lower than the desirable range.
IDDM -  Insulin dependant diabetes mellitus, now known as type 1 diabetes.
Immune system -  A system of the body that provides protection from infection.
Infusion Set -  Consists of a length of thin plastic tubing with a lock connector at one end, attached to a very small cannula placed under the skin. It is connected to the insulin pump and used to deliver insulin to the body.
Infusion Site -  The place on the body where the infusion set needle is inserted under the skin.
Injection -  The introduction of medication into the body with a delivery device eg. needle and syringe, pen, pump. A person with diabetes injects insulin by putting the needle into the tissue under the skin (called subcutaneous). Other ways of giving medicine or nourishment by injection are putting the needle into a vein (intravenous/IV) or putting the needle into a muscle (intramuscular/IM).
Injection Site -  The place on the body where the insulin is injected.
