A disease with excessive storage of iron, especially in the liver and
other tissues, including the pancreas and skin; it may be genetic or the
result of repeated transfusions. Pancreatic involvement may sometimes lead
to destruction of islet cells and to a secondary
form of diabetes.
Sometimes called "Bronze Diabetes" because of the association of
discoloration of the skin and diabetes.
A mechanical method of cleaning the blood for people who have kidney
disease. See also: Dialysis.
Hemoglobin A1C (HbA1C)
The substance of red blood cells that carries oxygen to the cells and
sometimes joins with glucose (sugar). Because the glucose stays attached for
the life of the cell (about 4 months), a test to
measure hemoglobin A1C shows what the person's average blood glucose
level was for that period of time.
See also: Glycohemoglobin.
The passing of a trait such as color of the eyes from parent to child. A
person "inherits" these traits through the genes.
High Blood Pressure
When the blood flows through the vessels at a greater than normal force.
High blood pressure strains the heart; harms the arteries; and increases the
risk of heart attack, stroke, and kidney problems. Also called hypertension.
A skin reaction that results in slightly elevated patches that are
redder or paler than the surrounding skin and often are accompanied by
HLA (Human Leukocyte Antigen)
A pattern of cell surface proteins that identifies the cell to the
immune system as 'self' or 'non-self'. Certain patterns (haplotypes) as
defined by DNA analysis can indicate a susceptibility to Type 1 diabetes.
Home Blood Glucose Monitoring
A way a person can test how much glucose (sugar) is in the blood. Also
called self-monitoring of blood glucose.

The period of time shortly after the diagnosis of Type
1 diabetes during which there is some restoration of insulin production
and the blood sugar levels improve to normal, or near-normal, levels.
Unfortunately, like other honeymoons, this diabetes honeymoon doesn't last
forever; it may last for weeks, months, or occasionally, years.
A chemical released by special cells to tell other cells what to do. For
instance, insulin is a hormone made by the beta cells in the pancreas. When
released, insulin tells other cells to use glucose (sugar) for energy.
Man-made insulins that are similar to insulin produced by your own body.
Human insulin has been available since October 1982.
Too high a level of glucose (sugar) in the blood; a sign that diabetes
is out of control. Many things can cause hyperglycemia. It occurs when the
body does not have enough insulin or cannot use the insulin it does have to
turn glucose into energy. Signs of hyperglycemia are a great thirst, a dry
mouth, and a need to urinate often. For people with Type 1 diabetes,
hyperglycemia may lead to diabetic
Hyperglycemic hyperosmolar nonketotic syndrome
See also: Euglycemia
Too high a level of insulin in the blood. This term most often refers to
a condition in which the body produces too much insulin. Researchers believe
that this condition may play a role in the development of
noninsulin-dependent diabetes and in hypertension.

Too high a level of fats (lipids) in the blood.

pressure that is above the normal range.

Too low a level of glucose (sugar) in the blood. This occurs when a
person with diabetes has injected too much insulin, eaten too little food,
or has exercised without extra food. A person with hypoglycemia may feel
nervous, shaky, weak, or sweaty, and have a headache, blurred vision, and
hunger. Taking small amounts of sugar, sweet juice, or food with sugar will
usually help the person feel better within 10-15 minutes.
See also: Euglycemia,
A situation in which the usual epinephrine-induced symptoms of a fall in
blood sugar are, for a variety of reasons, either not felt or not
This situation may be dangerous, as the patient may go from functioning
normally to unconscious within a short time. It is generally thought that if
such a patient is allowed to maintain somewhat elevated blood sugar
levels for several weeks, that the hypoglycemic unawareness may resolve.
pressure or a sudden drop in blood pressure. A person rising quickly
from a sitting or reclining position may have a sudden fall in blood
pressure, causing dizziness or fainting.
