WHAT IS DIABETES INSIPIDUS?
Diabetes insipidus is a condition in which the body cannot retain enough water. The patient is excessively thirsty and excretes large amounts of extremely diluted urine. It causes intense thirst and excretion of large amounts of urine. A reduction in fluid intake does not reduce amounts and consistency of urine excretion. It is a rare condition, affecting approximately 1 in every 25,000 people. Diabetes insipidus occurs because the body does not properly produce, store or release antidiuretic hormone (ADH) and kidneys do not respond properly to ADH.
SIGNIFICANT OF THE NAME DIABETES INSIPIDUS
Diabetes is a Greek word meaning “siphon”; it is derived from the verb diabainein, which means “to stand with legs apart or to go through.”
Insipidus is a Latin word meaning “without taste.” Diabetes insipidus involves the passing of urine that is tasteless because of its relatively low sodium content.
TYPES OF DIABETES INSIPIDUS
There are three types of diabetes insipidus. * Central diabetes insipidus -caused by damage to the hypothalamus or the pituitary gland from surgery, a tumor, meningitis,inflammation or a head injury, which disrupts ADH production, storage and release. Central diabetes insipidus that is caused by a head injury, or surgery to your pituitary gland, is sometimes only a temporary condition that lasts for just a couple of weeks. On some occasions the exact cause is never determined. * Nephrogenic diabetes insipidus - there is something wrong with the kidney tubules. The tubules cause fluids to be excreted or reabsorbed. Patients' kidneys do not respond properly to ADH. This may be caused by a congenital problem (inherited disorder) or some chronic (long-term) kidney disorder. Lithium, tetracycline and some other medications may also cause nephrogenic diabetes insipidus. * Gestational diabetes insipidus - occurs
