INTRODUCCIÓN:
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 theinsulin that is produced. This high blood sugar produces the classical symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphagia (increased hunger).
There are three main typesof diabetes:
* Type 1 diabetes: results from the body's failure to produce insulin, and presently requires the person to inject insulin.
* Type 2 diabetes: results from insulin resistance, acondition in which cells fail to use insulin properly, sometimes combined with an absolute insulin deficiency.
* 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.
All forms of diabetes have been treatable since insulin became available in 1921, and type 2 diabetes may becontrolled with medications. Both type 1 and 2 are chronic conditions that usually cannot be cured.
As of 2000 at least 171 million people worldwide suffer from diabetes, or 2.8% of the population,and in Argentina on 7% of sufferers.
Pathophysiology:
Cells metabolize glucose to make it a useful form of energy, which is why the body needs to be given glucose (through food), absorb (fordigestion) to circulate in the blood and distributed throughout the body, and finally, blood from inside the cells so it can be used. The latter only occurs under the influence of insulin in most cells of thebody (except: brain, liver, pancreas, kidney and erythrocytes cells), a hormone secreted by the pancreas.
In diabetes mellitus the pancreas does not produce or produces too little insulin (Type IDM) or the body's cells do not respond normally to the insulin that is produced (Type II DM).
This prevents or hinders the entry of glucose into the cell, increasing its levels in the blood...
