Insulin-dependent diabetes mellitus (IDDM) is the former term for Type 1 diabetes, where patients require external insulin for survival.

<dt class="glossary " id="" style="margin-top: 0.4em;">Insulin pen

<dt class="glossary " id="" style="margin-top: 0.4em;">Insulin pump

a device which provides a steady (or intermittent, depending on design and adjustments) infusion of insulin. Pumps can be implantable (see implantable insulin pump) or external. the latter use a subcutaneous catheter.

<dt class="glossary " id="" style="margin-top: 0.4em;">Insulin reaction

Too low a level of blood glucose (i.e., 'sugar') in the blood; also called hypoglycemia. This occurs when a person with diabetes has injected too much insulin, eaten too little food, or exercised without compensating for the increased glucose uptake caused by exercise. The person may feel hungry, nauseated, weak, nervous, shaky, confused, and sweaty. Eating small amounts of glucose converting sugar or starch (glucose, sucrose (1/2 glucose) or starch (all glucose)), sweet juice with glucose or sucrose, or food with such sugar will usually help the person feel better within 10–15 minutes. Fat or protein in the food or drink will delay absorption and should be avoided. So a glucose tablet is ideal, a candy bar or pastry is not (both contain fat in addition to starch and usually sugar). Orange juice works, but less well than intended, as its main carbohydrate is fructose. See also: Hypoglycemia; insulin shock.

<dt class="glossary " id="" style="margin-top: 0.4em;">Insulin receptors

Protein complexes on the surface of a cell that allows the cell to join or bind with insulin that is in the blood. When the vrll membrane receptor and insulin bind, the cell takes up glucose (sugar) from the blood and can use it for energy.

<dt class="glossary " id="" style="margin-top: 0.4em;">Insulin resistance

a condition in which a cell is resistant to insulin action, usually as a result of Type 2 diabetes which is characterized by insulin resistance in about two-thirds of the body's cells (those which require insulin in order to absorb glucose from the blood).

Formerly used, in hospitals, as a treatment for some kinds of mental illness. See also: Hypoglycemia; insulin reaction.

Moving the beta (islet) cells from a donor pancreas and putting them into a person whose pancreas has stopped producing insulin. The beta cells make the insulin that most cells in the human body require to absorb glucose from the blood. Transplanting islet cells may one day help many people with diabetes, and the procedure is currently in the experimental stage.

<dt class="glossary " id="" style="margin-top: 0.4em;">Islets of Langerhans

Groups of cells in the pancreas. Some of them make and secrete hormones that help the body break down and use food. They were noticed by Paul Langerhans, a German medical student, in 1869; these clusters throughout the pancreas serve several functions. There are currently five known types of cells in an islet: beta cells, which make insulin and C-peptide; alpha cells, which make glucagon; delta cells, which make somatostatin; F cells which make pancreatic polypeptide, and D1 cells, about which little is known. The names of the cell types vary with location; in the UK they have slightly different names than in the US.

<dt class="glossary " id="" style="margin-top: 0.4em;">Somatostatin

<dt class="glossary " id="" style="margin-top: 0.4em;">Somogyi effect

A swing to a high level of glucose (sugar) in the blood from an extremely low level, usually occurring after an untreated insulin reaction during the night. The swing is caused by the release of stress hormones to counter low glucose levels. 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 falling or low, adjustments in evening snacks or insulin doses may be recommended. This condition is named after Dr. Michael Somogyi, the man who first wrote about it. Also called "rebound hypoglycemia".

<dt class="glossary " id="" style="margin-top: 0.4em;">Sorbitol

<dt class="glossary " id="" style="margin-top: 0.4em;">Split dose

Division of a prescribed daily dose of insulin into two or more injections given over the course of a day. Also may be referred to as multiple injections. Many people who use insulin feel that split doses offer more consistent control over blood glucose (sugar) levels.

<dt class="glossary " id="" style="margin-top: 0.4em;">Stiff hand syndrome

<dt class="glossary " id="" style="margin-top: 0.4em;">Stroke

a non-traumatic interruption in the blood supply to an organ, particularly the brain. There are two varieties, the bleeding sort in which a blood vessel leaks blood into tissues. In the brain, these produce hematomas (i.e., pools of blood within the skull). The other kind is an ischemic stroke in which the flow of blood is interrupted, often because of vessel blockage by a clot or plaque. Both kill tissue and can cause considerable damage, including death.

<dt class="glossary " id="" style="margin-top: 0.4em;">Tolazamide

<dt class="glossary " id="" style="margin-top: 0.4em;">Toxemia of pregnancy (preeclampsia)

A condition in pregnant women involving high blood pressure, protein in the urine, and edema. It can harm both mother and child, but resolves after delivery. The first signs of toxemia are swelling near the eyes and ankles (edema), headache, high blood pressure, and weight gain that the mother might confuse with the normal weight gain of being pregnant. The mother may have both glucose (sugar) and acetone in her urine. The mother should tell the doctor about these signs at once. Women who become diabetic during their pregnancies have a 15% higher chance of developing preeclampsia; women who are diabetic before becoming pregnant have a 30% chance of developing preeclampsia.

<dt class="glossary " id="" style="margin-top: 0.4em;">Diabetes mellitus type 1

It is a chronic condition in which the pancreas makes little or no insulin because the beta cells have been destroyed. About two-thirds of body cells require insulin to absorb glucose and in its absence, they will not be able to use the glucose (blood sugar) for energy. Type 1 diabetes usually comes on abruptly, although the damage to the beta cells may begin much earlier. Typical signs of Type 1 diabetes are a great thirst, hunger, a need to urinate often, and loss of weight. To treat the disease, the person must inject insulin and test blood glucose frequently. Type 1 diabetes usually occurs in children and adults who are under age 30. This type of diabetes used to be known as "insulin-dependent diabetes," "juvenile diabetes," "juvenile-onset diabetes" and "ketosis-prone diabetes."

<dt class="glossary " id="" style="margin-top: 0.4em;">Diabetes mellitus type 2

The most common form of diabetes mellitus; about 90 to 95 percent of people who have diabetes in the developed world have Type 2 diabetes. Unlike Type 1 diabetes, in which the pancreas makes no insulin, people with Type 2 diabetes produce some insulin, sometimes even large amounts. However, either their bodies do not produce enough insulin or their body cells are resistant to insulin (see Insulin Resistance). People with Type 2 diabetes can often control their condition by losing weight through diet and exercise. If not, they may need to combine insulin or a pill with diet and exercise. Generally, Type 2 diabetes occurs in people who are over age 40. Most of the people who have this type of diabetes are overweight. This type of diabetes used to be known as "noninsulin-dependent diabetes," "adult-onset diabetes," "maturity-onset diabetes," "ketosis-resistant diabetes" and "stable diabetes."

Changes in the color of the strip show the amount of glucose or ketones in the urine. Urine testing is less desirable than blood testing for monitoring the level of glucose in the body. See also: Blood glucose monitoring; reagents.
