Endocrine glands - Glands that release hormones into the bloodstream. They affect how the body uses food (metabolism). They also influence other body functions. One endocrine gland is the pancreas. It releases insulin so the body can use sugar for energy. See also: gland.
Endocrinologist - A doctor who treats people who have problems with their endocrine glands. Diabetes is an endocrine disorder. See also: endocrine glands.
Endogenous - Grown or made inside the body. Insulin made by a person's own pancreas is endogenous insulin. Insulin that is made from beef or pork pancreas or derived from bacteria is exogenous because it comes from outside the body and must be injected.
Enzymes - A special type of protein. Enzymes help the body's chemistry work better and more quickly. Each enzyme usually has its own chemical job to do such as helping to change starch into glucose (sugar).
Epinephrine - One of the secretions of the adrenal glands. It helps the liver release glucose (sugar) and limits the release of insulin. It also makes the heart beat faster and can raise blood pressure; also called adrenalin.
Euglycemia - It is a condition in which the concentration of glucose in the blood is at normal levels (under 7 – 8mmol/l).
Extended bolus - An extended bolus is a programmable option with some insulin pumps. It permits delivery of insulin throughout a long meal, rather than a single fast-dose bolus.
