acanthosis (uh-kan-THO-sis) nigricans (NIH-grih-kans):
a skin condition characterized by darkened skin patches; common in people whose body is not responding correctly to the insulin that they make in their pancreas (insulin resistance). This skin condition is also seen in people who have pre-diabetes or type 2 diabetes.
an oral medicine used to treat type 2 diabetes. It blocks the enzymes that digest starches in food. The result is a slower and lower rise in blood glucose throughout the day, especially right after meals. Belongs to the class of medicines called alpha-glucosidase inhibitors. (Brand name: Precose.)
an oral medicine that lowers blood pressure; ACE stands for angiotensin (an-gee-oh-TEN-sin) converting enzyme. For people with diabetes, especially those who have protein (albumin) in the urine, it also helps slow down kidney damage.
acesulfame (a-see-SUL-fame) potassium (puh-TAS-ee-um):
a dietary sweetener with no calories and no nutritional value. Also known as acesulfame-K. (Brand name: Sunett.)
an oral medicine used to treat type 2 diabetes. It lowers blood glucose by helping the pancreas make more insulin and by helping the body better use the insulin it makes. Belongs to the class of medicines called sulfonylureas. (Brand name: Dymelor.)
describes something that happens suddenly and for a short time. Opposite of chronic.
adhesive capsulitis (cap-soo-LITE-is):
a condition of the shoulder associated with diabetes that results in pain and loss of the ability to move the shoulder in all directions.
former term for type 2 diabetes.

a condition in which the urine has more than normal amounts of a protein called albumin. Albuminuria may be a sign of nephropathy (kidney disease).
alpha (AL-fa) cell:
a type of cell in the pancreas. Alpha cells make and release a hormone called glucagon. The body sends a signal to the alpha cells to make glucagon when blood glucose falls too low. Then glucagon reaches the liver where it tells it to release glucose into the blood
alpha-glucosidase (AL-fa-gloo-KOH-sih-days) inhibitor:
a class of oral medicine for type 2 diabetes that blocks enzymes that digest starches in food. The result is a slower and lower rise in blood glucose throughout the day, especially right after meals. (Generic names: acarbose and miglitol.)
a hormone formed by beta cells in the pancreas. Amylin regulates the timing of glucose release into the bloodstream after eating by slowing the emptying of the stomach.
a type of neuropathy resulting in pain, weakness, and/or wasting in the muscles.
a condition in which the number of red blood cells is less than normal, resulting in less oxygen being carried to the body’s cells.
any disease of the blood vessels (veins, arteries, capillaries) or lymphatic vessels.
proteins made by the body to protect itself from “foreign” substances such as bacteria or viruses. People get type 1 diabetes when their bodies make antibodies that destroy the body’s own insulin-making beta cells.
a test that measures a person’s average blood glucose level over the past 2 to 3 months. Hemoglobin (HEE-mo-glo-bin) is the part of a red blood cell that carries oxygen to the cells and sometimes joins with the glucose in the bloodstream. Also called hemoglobin A1C or glycosylated (gly-KOH-sih-lay-ted) hemoglobin, the test shows the amount of glucose that sticks to the red blood cell, which is proportional to the amount of glucose in the blood.
an oral medicine that lowers blood pressure; ARB stands for angiotensin (an-gee-oh-TEN-sin) receptor blocker.
hardening of the arteries.
a large blood vessel that carries blood with oxygen from the heart to all parts of the body.
aspart (ASS-part) insulin:

a steady trickle of low levels of longer-acting insulin, such as that used in insulin pumps.
a cell that makes insulin. Beta cells are located in the islets of the pancreas.
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.)
the main sugar found in the blood and the body’s main source of energy. Also called blood sugar.
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 glucose meter:
a small, portable machine used by people with diabetes to check their blood glucose 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.
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.

tubes that carry blood to and from all parts of the body. The three main types of blood vessels are arteries, veins, and capillaries.
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.
an extra amount of insulin taken to cover an expected rise in blood glucose, often related to a meal or snack.
a former term for type 2 diabetes or impaired glucose tolerance.
a term used when a person’s blood glucose level moves often from low to high and from high to low.

loss of the heart’s pumping power, which causes fluids to collect in the body, especially in the feet and lungs.
a term used in clinical trials where one group receives treatment for diabetes in which A1C and blood glucose levels are kept at levels based on current practice guidelines. However, the goal is not to keep blood glucose levels as close to normal as possible, as is done in intensive therapy. Conventional therapy includes use of medication, meal planning, and exercise, along with regular visits to health care providers.

coronary (KOR-uh-ner-ee) heart disease:
heart disease caused by narrowing of the arteries that supply blood to the heart. If the blood supply is cut off the result is a heart attack.
“Connecting peptide,” a substance the pancreas releases into the bloodstream in equal amounts to insulin. A test of C-peptide levels shows how much insulin the body is making.
a waste product from protein in the diet and from the muscles of the body. Creatinine is removed from the body by the kidneys; as kidney disease progresses, the level of creatinine in the blood increases.
