MT Training > Terminology > Diabetes

Nephropathy: Disease of the kidneys caused by damage to the small blood vessels or to the units in the kidneys that clean the blood. People who have had diabetes for a long time may develop nephropathy.

Neurologist: A doctor who treats people who have problems of the nervous system (brain, spinal cord and nerves).

Neuropathy: Nerve damage. People who have had diabetes that is not well controlled may develop nerve damage.

Non-insulin dependent diabetes: Former term for type 2 diabetes.

Nutritionist: See Dietitian

Obesity: A term uses to describe excess body fat. It is defined in terms of a person's weight and height, or the body mass index (BMI). A BMI (body mass index) over 30 is classified as being obese. Obesity makes your body less sensitive to insulin's action. Extra body fat is thought to be a risk factor for diabetes.

Ophthalmologist: A doctor who treats people with eye diseases.

Optometrist: A person professionally trained to test the eyes and to detect and treat eye problems, as well as some diseases, by prescribing and adapting corrective lenses.

Oral diabetes medications: Medications that people take to lower the level of glucose in the blood. Oral diabetes medications are prescribed for people whose pancreas still produces some insulin. These medications are not used in diabetes during pregnancy.

Pancreas: An organ behind the lower part of the stomach that is about the size of a hand. It makes insulin so the body can use glucose (sugar) for energy.

Peak action: The time when the effect of something is as strong as it can be, such as when insulin is having the most effect on blood glucose.

Periodontal disease: Damage to the gums and tissues around the teeth. People who have diabetes are more likely to have periodontal disease than people who do not have diabetes.

Peripheral neuropathy: A type of nerve damage most commonly affecting the feet and legs.

Peripheral vascular disease (PVD): An abnormal condition that affects the blood vessels outside the heart. Often occurs as a result of decreased blood flow and narrowing of the arteries from atherosclerosis, to the hands and feet. People who have had diabetes for a long time may develop PVD.

Podiatrist: A health professional who diagnoses and treats foot problems.

Polydipsia: Excessive thirst that lasts for long periods of time; may be a sign of diabetes.

Polyphagia: Excessive hunger and eating; may be a sign of diabetes. People with polyphagia often lose weight even though they are eating more than normal.

Polyunsaturated fat: A type of fat that can be substituted for saturated fats in the diet and can reduce 'bad' LDL cholesterol. It can have a small effect in lowering 'good' HDL cholesterol as well, but not to the degree that saturated fats do. .

Polyuria: Increased need to urinate often; a common sign of diabetes.

Protein: One of three main classes of food. Proteins are made of amino acids, which are called the "building blocks of the cells." Cells need protein to grow and to mend themselves. Protein is found in many foods, like meat, fish, poultry, eggs, legumes and dairy products.

Rebound effect: See Somogyi effect

Regular insulin: A type of insulin that is rapid-acting.
 

Renal: Relating to the kidneys.

Retina: The center part of the back lining of the eye that senses light. It has many small blood vessels that are sometimes harmed when a person has had diabetes for a long time.

Retinopathy: A disease of the small blood vessels in the retina of the eye.

Risk factor: Anything that increases the chance of a person developing a disease or condition.

Saccharin: An artificial sweetener that is used in place of sugar because it has no calories and does not increase blood glucose.

Self-blood glucose monitoring: See Home blood glucose monitoring

Somogyi effect: Also called "rebound effect," it occurs when there is a upward swing in blood sugar from an extremely low level of glucose in the blood to a very high level. It usually happens during the night and early A.M. morning hours. People who experience high levels of blood glucose in the morning may need to test their blood glucose levels in the middle of the night. If blood glucose levels are repeatedly low, addition of an evening snack or a lowering of the insulin doses may be recommended.

Sorbitol: A sugar -- produced from fruits -- that the body uses slowly. It is a sweetener used in diet foods and is called a "nutritive sweetener" because it has four calories in every gram, just like table sugar and starch. These compounds are used in many foods labeled as 'sugar free' and 'no sugar added' and can raise your blood glucose. Because a food is labeled 'sugar free,' it doesn't necessarily mean carbohydrate free.

Sucrose: Table sugar; a form of sugar that the body must break down into a more simple form before the blood can absorb it and take it to the cells.

Sugar: A class of carbohydrates that tastes sweet. Sugar is a quick and easy fuel for the body to use. Some types of sugar are lactose, glucose, fructose and sucrose.

Sulfonylureas: Pills or capsules that people take to lower the level of glucose in the blood. These oral diabetic medications work to lower your blood glucose by making your pancreas produce more insulin.

Triglyceride: Fats carried in the blood from the food we eat. Most of the fats we eat, including butter, margarines and oils, are in triglyceride form. Excess triglycerides are stored in fat cells throughout the body. The body needs insulin to remove this type of fat from the blood.

Type 1 diabetes: A type of diabetes in which the insulin-producing cells (called beta cells) of the pancreas are damaged. People with type 1 diabetes produce little or no insulin, so glucose cannot get into the body's cells for use as energy. This causes blood glucose to rise. People with type 1 diabetes must use insulin injections to control their blood glucose.

Type 2 diabetes: A type of diabetes in which the insulin produced is either not enough or the person's body does not respond normally to the amount present. When there is not enough insulin or the insulin is not used as it should be, glucose cannot get into the body's cells for use as energy. This causes blood glucose to rise.

U-100: See Unit of insulin

Ulcer: A break in the skin; a deep sore. People with diabetes may develop ulcers from minor scrapes on the feet or legs, from cuts that heal slowly, or from the rubbing of shoes that don't fit well. Ulcers can become infected and should be treated promptly.

Ultralente insulin: A type of insulin that is long acting, usually the action of this type of insulin works for 25-36 hours after injection. This type of insulin has an onset of action four to five hours after injecting and works most powerfully at eight to -14 hours after injection.

Unit of insulin: The basic measure of insulin. U-100 is the most common concentration of insulin. U-100 means that there are 100 units of insulin per milliliter (ml) of liquid. For the occasional patient that has severe insulin resistance insulin is available as a U-500 form.

Unstable diabetes: See Brittle diabetes

Urine testing: Checking urine to see if it contains ketones. If you have type 1 diabetes, are pregnant and have diabetes or have gestational diabetes, your doctor may ask you to check your urine for ketones. This is an easy test done at home with a dipstick measure.

Urologist: A doctor who specializes in treatment of the urinary tract for men and women, as well as treatment of the genital organs for males.

Vaginitis: An inflammation or infection of the vaginal tissues. A woman with this condition may have itching or burning or vaginal discharge. Women who have diabetes may develop vaginitis more often than women who do not have diabetes.

Vascular: Relating to the body's blood vessels (arteries, veins and capillaries).

Vein: A blood vessel that carries blood to the heart.

Vitrectomy: A procedure in which the gel from the center of the eyeball is removed because it has blood and scar tissue in it that blocks vision. An eye surgeon replaces the clouded gel with a clear fluid.

Xylitol: A nutritive sweetener used in dietary foods. It is a sugar alcohol that the body uses slowly and contains fewer calories than table sugar.
