BLOOD GLUCOSE: The concentration of glucose in the blood. In Canada, blood glucose is measured in mmol of glucose per litre of blood (mmol/L). The normal range before meals is 4.0 - 6.0 mmol/L, while the normal range two hours after a meal is 5.0 - 8.0 mmol/L.

 

BLOOD GLUCOSE METER/MONITOR: A hand-held machine designed to test blood glucose levels. A drop of blood (usually from the fingertip) is placed on a small test strip that is inserted into the meter. The meter displays the amount of glucose in the blood. Blood glucose meters allow people with diabetes to play an active role in monitoring their own blood glucose levels.

 

BLOOD PRESSURE: Blood pressure is expressed using two numbers: the first number is systolic pressure, the pressure caused by the heart pushing blood into the arteries. The second number is diastolic pressure, the pressure when the heart is relaxed and refilling with blood. High blood pressure (hypertension) is a major risk factor for cardiovascular disease, diabetic nephropathy and diabetic retinopathy. To reduce the risk of these complications, people with diabetes should aim for a blood pressure of 130/80 mm Hg or lower.
 

C

CARDIOLOGIST: A medical doctor who specializes in diagnosing and treating conditions of the heart and blood vessels.

 

CARBOHYDRATE: One of the main sources of calories. Sources of carbohydrates include starches such as breads, cereals, rice, pasta, potatoes, corn and legumes.  Sources also include sugars naturally found in honey, fruits, vegetables and milk; refined sugars such as table sugar and sugars added to candies, jams and soft drinks. All forms of carbohydrate are broken down into glucose during digestion.

 

CERTIFIED DIABETES EDUCATOR (CDE): A Certified Diabetes Educator (CDE) is a health professional, committed to excellence in diabetes education, who has a sound knowledge base in diabetes care/management and education processes, as well as good communication skills. A CDE has passed the Canadian Diabetes Educator's Certification Board (CDECB) exam.

 

COMA: A state of unconsciousness. In diabetes, it may result from a variety of causes including severe hypoglycemia or diabetic ketoacidosis.

 

COMMUNITY HEALTH CENTRE (CHC): A Community Health Centre (CHC) is a non-profit, publicly funded organization that provides primary health care from a team of doctors, nurse practitioners, registered nurses, registered dietitians, social workers and community health workers. The multidisciplinary team ensures the patient gets the right care, at the right time, delivered by the most appropriate provider. The focus of a CHC is on health promotion, illness prevention, and community development.

G

GASTROPARESIS: A form of nerve damage (neuropathy) that affects the stomach and intestines, causing them to take too long to empty their contents. Diabetes is a major cause of gastroparesis.

 

GESTATIONAL DIABETES MELLITUS (GDM): Diabetes that is first diagnosed or first develops during pregnancy. It affects 4% to 20% of all pregnancies. Blood glucose levels usually return to normal following delivery. Both mother and child are at higher risk of developing type 2 diabetes later in life.

 

GLUCAGON: A hormone produced by the pancreas that causes an increase in the blood glucose level, and thus has the opposite effect of insulin. Glucagon can also be given by injection to treat severe hypoglycemia.
 

GLUCOSE: A simple form of sugar that acts as fuel for the body. It is produced from digestion of carbohydrate and carried in the blood to the body’s cells.

 

GLYCEMIC INDEX: A scale that ranks carbohydrate-rich foods by how quickly they raise blood glucose levels.

H

HYPERGLYCEMIA (also HYPERGLYCAEMIA): Higher than normal levels of glucose in the blood. Symptoms depend on how high the blood glucose level is, but can include thirst, frequent urination, blurred vision and fatigue.

 

HYPOGLYCEMIA: Lower than normal blood glucose. Symptoms depend on how low the blood glucose level is and include sweating, trembling, hunger, dizziness, moodiness, confusion, headache, blurred vision and nausea.

 

HYPOTHYROIDISM: A disease in which the production of thyroid hormone is reduced. Symptoms include slow metabolism, tendency to gain weight and fatigue.
 

I
INSULIN: A hormone produced by the beta cells of the pancreas that controls the amount of glucose in the blood. Insulin lowers blood glucose by helping move glucose into the body’s cells, where it is used as fuel. 

 

INSULIN PEN: An injection device the size of a pen that includes a needle and holds a cartridge of insulin. It can be used instead of syringes for giving insulin injections.

 

INSULIN PUMP: A portable, battery-operated device that delivers a specific amount of insulin through a small needle inserted under the skin. It can be programmed to deliver constant doses of insulin throughout the day and deliver extra insulin at meals and as required. Also called continuous subcutaneous insulin infusion (CSII).

 

INSULIN RESISTANCE: A condition in which the body’s cells and tissues do not respond properly to the effects of insulin. It is a key feature of type 2 diabetes.

 

INTERNIST: A medical doctor who specializes in the diagnosis and medical treatment of internal organs, illnesses, diseases, and chronic conditions.

K

KETONES: Products created when fat is broken down to be used for energy. The body normally gets rid of excess ketones in the urine. However, if levels of ketones get too high, they accumulate in the body and can lead to ketoacidosis, coma and even death.
 

L

LANCET: A fine, sharp-pointed blade or needle for pricking the skin, used to obtain a blood sample for blood glucose testing.

 

LHIN: Local Health Integration Network. LHINs are funded by the Ontario MOHLTC and are responsible for planning, coordinating, funding and monitoring their local health system. Many health service providers are funded through the LHINs, including hospitals, most psychiatric facilities, long-term care homes, Community Care Access Centres, community service providers and community mental health and addiction agencies.
