blood glucose level
the amount of glucose in a given amount of blood. It is noted in milligrams in a deciliter, or mg/dL.
blood sampling devices
a small instrument for pricking the skin with a fine needle to obtain a sample of blood to test for glucose (sugar).
blood pressure
the force of blood exerted on the inside walls of blood vessels. Blood pressure is expressed as a ratio (example: 120/80, read as “120 over 80”). The first number is the systolic (sis-TAH-lik) pressure, or the pressure when the heart pushes blood out into the arteries. The second number is the diastolic (DY-uh-STAH-lik) pressure, or the pressure when the heart rests.
blood sugar
see blood glucose
blood urea nitrogen
(yoo-REE-uh NY-truh-jen) (BUN):
blood vessels
tubes that carry blood to and from all parts of the body. The three main types of blood vessels are arteries, veins, and capillaries.
BMI
see body mass index.
body mass index (BMI)
a measure used to evaluate body weight relative to a person`s height. BMI is used to find out if a person is underweight, normal weight, overweight, or obese.
bolus
(BOH-lus):
an extra amount of insulin taken to cover an expected rise in blood glucose, often related to a meal or snack.
borderline diabetes
a former term for pre-diabetes or impaired glucose tolerance.
brittle diabetes
a term used when a person`s blood glucose level moves often from low to high and from high to low.
bunion
(BUN-yun):
a bulge on the first joint of the big toe, caused by the swelling of a fluid sac under the skin. This spot can become red, sore, and infected.
background retinopathy
(REH-tih-NOP-uh-thee):
a type of damage to the retina of the eye marked by bleeding, fluid accumulation, and abnormal dilation of the blood vessels. Background retinopathy is an early stage of diabetic retinopathy. Also called simple or nonproliferative (non-pro-LIF-er-uh-tiv) retinopathy.
basal rate
a steady trickle of low levels of longer-acting insulin, such as that used in insulin pumps.
biguanide
(by-GWAH-nide):
a class of oral medicine used to treat type 2 diabetes that lowers blood glucose by reducing the amount of glucose produced by the liver and by helping the body respond better to insulin. (Generic name: metformin.)
blood glucose
blood glucose, or commonly referred to as blood sugar, is the form of energy circulating in the blood stream. Blood glucose is the end result of digestion, absorption and metabolism of food.
blood glucose meter
a small, portable machine used by people with diabetes to check their blood sugar levels. After pricking the skin with a lancet, one places a drop of blood on a test strip in the machine. The meter (or monitor) soon displays the blood glucose level as a number on the meter`s digital display.
blood glucose monitoring
checking blood glucose level on a regular basis in order to manage diabetes. A blood glucose meter (or blood glucose test strips that change color when touched by a blood sample) is needed for frequent blood glucose monitoring.
