either of two disorders – diabetes insipidus or diabetes mellitus. insipidus denotes a metabolic disorder of the hormone system caused by a deficiency of antidiuretic hormone (adh) normally secreted by the pituitary gland. usually a temporary condition. characterised by passage of large amounts of diluted, colourless urine (up to 15 quarts a day), unquenchable thirst, dry skin and constipation.
diabetes mellitus is a chronic metabolic disorder due to insufficient insulin, symptoms include excessive thirst and urination, weight loss, excess sugar in urine and blood. two forms of diabetes mellitus are type 1, or juvenile-onset diabetes, and type 2 or adult- onset diabetes. treatment depends upon ability to produce insulin. insulent dependent: those with an inability to produce enough insulin to process carbohydrates, fat and protein efficiently will require insulin injections. non insulin dependent – most prevalent amongst obese adults often controlled with weight loss exercise and diet.
