acanthosis nigricans (ak-an-THOH-siss) (NIG-rih-kanz):
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, a condition called insulin resistance. This skin condition is also seen in people who have prediabetes or type 2 diabetes.
an oral medicine used to treat type 2 diabetes. Acarbose slows down the digestion of foods high in carbohydrate, such as rice, bread, milk, and fruit. The result is a slower and lower rise in blood glucose throughout the day, especially right after meals. Acarbose belongs to the class of medicines called alpha-glucosidase inhibitors. (Brand name: Precose.)
ACE inhibitor (ayss) (in-HIB-ih-tur):
an oral medicine that lowers blood pressure; ACE stands for angiotensin-converting enzyme. For people with diabetes, especially those who have protein (albumin) in the urine, it also helps slow down kidney damage.
acesulfame potassium (AY-see-SUHL-faym) (poh-TASS-ee-uhm):
a dietary sweetener with no calories and no nutritional value. Also known as acesulfame-K. (Brand name: Sunett.)
Actoplus Met (AK-toh-pluhss) (met):
the brand name of an oral medicine used to treat type 2 diabetes; a combination of pioglitazone and metformin.
describes something that happens suddenly and for a short time. Opposite of chronic, or long lasting.
acute renal failure (uh-KYOOT) (REE-nuhl) (FAYL-yoor):
sudden and temporary loss of kidney function. See chronic kidney disease.
adhesive capsulitis (ad-HEE-siv) (KAP-soo-LY-tiss):
a condition of the shoulder associated with diabetes that results in pain and loss of the ability to move the shoulder in all directions.
adult-onset diabetes (uh-DUHLT-AWN-set) (DY-uh-BEE-teez):
former term for type 2 diabetes.
stands for advanced glycosylation end products. AGEs are produced in the body when glucose links with protein. They play a role in damaging blood vessels, which can lead to diabetes complications.
the main protein in blood. Over several years, people who are developing diabetic kidney disease leak small amounts of albumin into the urine, a condition called microalbuminuria. As kidney disease progresses, more albumin leaks into the urine, a condition called macroalbuminuria or proteinuria. As the amount of albumin in the urine increases, the kidneys' ability to filter the blood decreases.
a condition in which the urine has more than normal amounts of a protein called albumin. Albuminuria may be a sign of nephropathy, or kidney disease. See albumin.
alpha cell (AL-fuh) (sel):
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 the liver to release glucose into the blood for energy.
alpha-glucosidase inhibitor (AL-fuh-gloo-KOH-sih-dayss) (in-HIB-ih-tur):
a class of oral medicine for type 2 diabetes that slows down the digestion of foods high in carbohydrate, such as rice, bread, milk, and fruit. The result is a slower and lower rise in blood glucose after meals. (Generic names/Brand names: acarbose/Precose; miglitol/Glyset.)
alternative site testing:
using areas of the body other than the fingertips for blood glucose monitoring.
to cut a part, such as a foot, from the body.
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.
amylin mimetic (AM-ih-lin) (mih-MET-ik):
a type of injectable medicine for diabetes that mimics the effect of the hormone amylin. This medicine helps food move more slowly through the stomach and helps keep the liver from releasing stored glucose. (Generic name/Brand name: pramlintide acetate/ Symlin.)
a type of neuropathy resulting in pain, weakness, 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. Anemia can cause extreme fatigue.
any disease of the blood vessels (arteries, capillaries, veins) 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 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 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. Results are given as a percentage or as an average glucose value, called an estimated average glucose.
see insulin glulisine.
an oral medicine that lowers blood pressure. ARB stands for angiotensin receptor blocker. For people with diabetes, especially those who have protein (albumin) in the urine, it also helps slow down kidney damage.
a large blood vessel that carries blood with oxygen from the heart to all parts of the body.
a dietary sweetener with almost no calories and no nutritional value.
clogging, narrowing, and hardening of the body's large blood vessels, also called arteries. Atherosclerosis can lead to coronary heart disease, heart attacks, peripheral arterial disease, strokes, and transient ischemic attacks. It can also damage the arteries that go to the kidneys.
athlete's foot (ATH-leets) (fut):
a fungal infection of the skin on the foot, also called tinea pedis. The fungus is common in people with diabetes, the elderly, and people with an impaired immune system. The skin may peel, crack, bleed, or cause pain. Some people have no symptoms and do not know they have an infection. The affected skin is also more vulnerable to bacteria that cause cellulitis.
autoimmune disease (AW-toh-ih-MYOON) (dih-ZEEZ):
a disorder of the body's immune system in which the immune system mistakenly attacks and destroys body tissue that it believes to be foreign.
autonomic neuropathy (AW-toh-NOM-ik) (noo-ROP-uh-thee):
a type of neuropathy affecting the lungs, heart, stomach, intestines, bladder, or genitals.
the brand name of an oral medicine used to treat type 2 diabetes; a combination of rosiglitazone and metformin.
the brand name of an oral medicine used to treat type 2 diabetes; a combination of rosiglitazone and glimepiride.

blood glucose monitoring (bluhd) (GLOO-kohss) (MON-ih-TUR-ing):
checking blood glucose levels by using a blood glucose meter or blood glucose test strips that change color when touched by a blood sample in order to manage diabetes.
the force of blood exerted on the inside walls of blood vessels. Blood pressure is expressed as two numbers. For example, a blood pressure result of 120/80 is said as "120 over 80." The first number is the systolic pressure, or the pressure when the heart pushes blood into the arteries. The second number is the diastolic pressure, or the pressure when the heart rests.

a fungus that is normally found in the body but commonly becomes overgrown in people with diabetes. Overgrowth is due to increased sugar in the body and a weakened immune system. Use of antibiotics or birth control pills also increases the risk of candida overgrowth. Candida overgrowth can lead to infection, causing itching, skin lesions, or rash. Some common areas of infection are in or around the mouth, armpits, groin, vagina, and nails.

simple sugar found in blood that serves as the body's main source of energy. Also called glucose.
a condition characterized by hyperglycemia (high blood glucose) resulting from the body's inability to use blood glucose for energy. In type 1 diabetes, the pancreas no longer makes insulin; therefore, blood glucose cannot enter the cells to be used for energy. In type 2 diabetes, either the pancreas does not make enough insulin or the body is unable to use insulin correctly. Also called diabetes mellitus.
Diabetes Control and Complications Trial (DCCT) (DY-uh-BEE-teez) (kon-TROHL) (and) (KOM-plih-KAY-shuhnz) (TRY-uhl):
a study by the National Institute of Diabetes and Digestive and Kidney Diseases, conducted from 1983 to 1993 in people with type 1 diabetes.

a study by the National Institute of Diabetes and Digestive and Kidney Diseases conducted from 1998 to 2001 in people at high risk for type 2 diabetes. All study participants had impaired glucose tolerance, also called prediabetes, and were overweight. The study showed that people who lost 5 to 7 percent of their body weight through a low-fat, low-calorie diet and moderate physical activity-usually walking for 30 minutes 5 days a week-reduced their risk of getting type 2 diabetes by 58 percent. Participants who received treatment with the oral diabetes drug metformin reduced their risk of getting type 2 diabetes by 31 percent.

causing diabetes. For example, some drugs cause blood glucose levels to rise, resulting in diabetes.
a doctor who specializes in treating people who have diabetes.
the determination of a disease from its signs and symptoms.
the process of cleaning wastes from the blood artificially. This job is normally done by the kidneys. If the kidneys fail, the blood must be cleaned artificially with special equipment. The two major forms of dialysis are hemodialysis and peritoneal dialysis.
- hemodialysis (HEE-moh-dy-AL-ih-siss): the use of a machine to clean wastes from the blood after the kidneys have failed. The blood travels through tubes to a dialyzer, a machine that removes wastes and extra fluid. The cleaned blood then flows through another set of tubes back into the body.
- peritoneal dialysis (PAIR-ih-toh-NEE-uhl) (dy-AL-ih-siss): cleaning of the blood by using the lining of the abdominal cavity, or belly, as a filter. A cleansing liquid, called dialysis solution, is drained from a bag into the abdomen. Fluid and wastes flow through the lining of the abdominal cavity and remain "trapped" in the dialysis solution. The solution is then drained from the abdomen, removing the extra fluid and wastes from the body. The two main types of peritoneal dialysis are continuous ambulatory peritoneal dialysis and continuous cycling peritoneal dialysis.
- continuous ambulatory peritoneal dialysis (CAPD) (kon-TIN-yoo-uhss) (AM-byoo-luh-TOR-ee) (PAIR-ih-toh-NEE-uhl) (dy-AL-ih-siss): a form of peritoneal dialysis that needs no machine. With CAPD, the blood is always being cleaned. The dialysis solution passes from a plastic bag through a catheter and into the abdomen. The dialysis solution stays in the abdomen with the catheter sealed. After several hours, the person using CAPD drains the solution back into a disposable bag. Then the person refills the abdomen with fresh solution through the same catheter to begin the cleaning process again.
- continuous cycling peritoneal dialysis (CCPD) (kon-TIN-yoo-uhss) (SY-kling) (PAIR-ih-toh-NEE-uhl) (dy-AL-ih-siss): a form of peritoneal dialysis that uses a machine. This machine automatically fills and drains the dialysis solution from the abdomen. A typical CCPD schedule involves three to five exchanges during the night while the person sleeps. During the day, the person using CCPD performs one exchange, draining the dialysis solution after an entire day.
dialysis solution (dy-AL-ih-siss) (suh-LOO-shuhn):
a cleansing liquid used in the two major forms of dialysis-hemodialysis and peritoneal dialysis. Dialysis solution contains dextrose, a sugar, and other chemicals similar to those in the body. Dextrose draws wastes and extra fluid from the body into the dialysis solution.
diastolic pressure (DY-uh-STOL-ik) (PRESH-ur):
the blood pressure when the heart rests.
a health care professional who advises people about meal planning, weight control, and diabetes management. A registered dietitian (RD) has met certain requirements.
dilated eye exam (DY-lay-ted) (eye) (ek-ZAM):
a test done by an eye care specialist in which the pupil-the black center-of the eye is temporarily enlarged with eyedrops to allow the specialist to see the inside of the eye more easily.
dipeptidyl peptidase-4 inhibitor (dy-PEP-tih-dil) (PEP-tih-dayss-FOR) (in-HIB-ih-tur):
see DPP-4 inhibitor.
see diabetic ketoacidosis.
D-phenylalanine derivative (DEE-FEN-il-AL-uh-neen) (duh-RIV-uh-tiv):
a type of oral medicine for type 2 diabetes that lowers blood glucose levels by helping the pancreas make more insulin right after meals. (Generic name/Brand name: nateglinide/Starlix.)
see Diabetes Prevention Program.
DPP-4 inhibitor (DEE-PEE-PEE-FOR) (in-HIB-ih-tur):
a class of oral medicine used to treat type 2 diabetes that lowers blood glucose by helping the body make more insulin when it's needed. This type of medicine also helps keep the liver from putting stored blood glucose into the blood. (Generic name/Brand name: sitagliptin phosphate/Januvia.)
the brand name of an oral medicine used to treat type 2 diabetes; a combination of pioglitazone and glimepiride.
Dupuytren's contracture (doo-pwee-TRENZ) (kon-TRAK-chur):
a condition associated with diabetes in which the fingers and the palm of the hand thicken and shorten, causing the fingers to curve inward.
in referring to insulin, the length of time during which insulin keeps lowering blood glucose levels. Duration may also refer to the length of time a person has had diabetes, which determines a person's risk of developing diabetes complications.
