Hypoglycemia unawareness
A condition in which a person does not feel or recognize the
symptoms of hypoglycemia.
Infusing
Introducing a liquid substance under the skin into the body.
Infusion site
Place on the body where an infusion set is inserted.
Insulin
A hormone that helps the body use glucose for energy. The beta
cells of a healthy pancreas make insulin.
Insulin on board (active insulin)
The amount of insulin that is still “active” in the body from a previ-
ous correction bolus dose. The amount of time insulin remains
“on board” or “active” depends on each individual’s duration of
insulin action. Talk with your healthcare provider to determine
your duration of insulin action.
The OmniPod System continually calculates this number to help
prevent “stacking” of correction bolus doses, which is a major
cause of hypoglycemia.
Insulin reaction (see hypoglycemia)
Insulin-to-carbohydrate ratio
Number of grams of carbohydrate covered by one unit of insulin.
For example, if your insulin-to-carbohydrate ratio is 1:50, then
you need to deliver one unit of insulin to cover every fifty grams
of carbohydrate you eat.
In vitro
Literally, “in glass.” Refers to a biological function taking place in a
laboratory dish rather than in a living organism.
Ketoacidosis (diabetic ketoacidosis or DKA)
A very serious condition in which extremely high blood glucose
levels and a severe lack of insulin cause the body to break down
fat for energy. The breakdown of fat releases ketones into the
blood and urine. DKA can take hours or days to develop, with
symptoms that include stomach pain, nausea, vomiting, fruity
breath odor, and rapid breathing.
Ketones
Acidic by-products that result from the breakdown of fat for
energy. The presence of ketones indicates that the body is using
stored fat and muscle (instead of glucose) for energy.
It is important to rule out ketoacidosis when you
experience symptoms that might otherwise indicate
the flu.
