Insulin pump

Neck | Endocrinology and Metabolism | Insulin pump (Disease)


A patient that suffers from diabetes has a chronic disease in which the body is unable to regulate blood sugar properly. As a result, blood sugar levels become abnormally high. Blood sugar, or glucose, is an important source of energy for all cells in the body. Insulin is a hormone made by the pancreas. Insulin regulates the level of glucose in the bloodstream.

The three main types of diabetes mellitus (DM) are:

(1) Type 1 DM results from the bodys failure to produce insulin, and presently requires the person to inject insulin. (Also referred to as insulin-dependent diabetes mellitus (IDDM) or juvenile diabetes)

(2) Type 2 DM results from insulin resistance, a condition in which cells fail to use insulin properly, sometimes combined with an absolute insulin deficiency. (Formerly referred to as noninsulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes)

(3) Gestational diabetes is when pregnant women, who have never had diabetes before, have a high blood glucose level during pregnancy. It may precede development of type 2 DM.

Causes and Risk factors

Diabetes mellitus, often simply referred to as diabetes, is a group of metabolic diseases in which a person has high blood sugar, either because the body does not produce enough insulin, or because cells do not respond to the insulin that is produced. This high blood sugar produces the classical symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphagia (increased hunger).

Diagnosis and Treatment

The insulin pump is a medical device used for the administration of insulin in the treatment of diabetes mellitus, also known as continuous subcutaneous insulin infusion therapy. The device includes:

•the pump itself (including controls, processing module, and batteries)

•a disposable reservoir for insulin (inside the pump)

•a disposable infusion set, including a cannula for subcutaneous insertion (under the skin) and a tubing system to interface the insulin reservoir to the cannula.

An insulin pump is an alternative to multiple daily injections of insulin by insulin syringe or an insulin pen and allows for intensive insulin therapy when used in conjunction with blood glucose monitoring and carb counting

Insulin pump allows the replacement of long-acting insulin (for basic needs) with a continuous infusion of insulin (small amounts) with short duration of action but fast. ...
