Diabetes insipidus (di) is defined as the passage of large volumes (>3 l/24 h) of dilute urine (< 300m osm/kg). di has 2 major forms: central and nephrogenic. central di is characterized by decreased secretion of antidiuretic hormone (adh)—also known as arginine vasopressin (avp)—which gives rise to polyuria and polydipsia by diminishing.

Diabetes insipidus is caused by abnormality in the functioning or levels of antidiuretic hormone (adh), also known of as vasopressin. manufactured in the hypothalamus and stored in the pituitary. Diabetesinsipidus. 5-10 units im/sc q8-12hr. titrate dose on basis of serum sodium, serum osmolality, fluid balance, and urine output. abdominal roentgenography. 10 units (0. 5ml) diabetes insipidus medscape im/sc 2 hours before procedure, then 10 units im 30 minutes before procedure. may give enema prior to first dose of vasopressin. dosage modifications. Diabetes insipidus (di) is part of a group of hereditary or acquired polyuria and polydipsia diseases in which the kidneys pass large amounts of water irrespective of the body's hydration state. di is due either to (1) deficient secretion of adh by the pituitary gland (central or neurogenic di) or to (2) renal tubular unresponsiveness to. Nephrogenic diabetes insipidus is a disorder in which a defect in the small tubes (tubules) in the kidneys causes a person to produce a large amount of urine. nephrogenic diabetes insipidus occurs when the kidney tubules, which allow water to be removed from the body or reabsorbed, do not respond to a chemical in the body called antidiuretic hormone or vasopressin.

In adults, nephrogenic diabetes insipidus most often develops as a result of lithium toxicity or hypercalcemia. impairment of urinary concentration occurs in up to 20% of patients taking lithium, as a result of dysregulation of the aquaporin system in principal cells of the collecting duct.
