A fluid or water deprivation test is a medical test [1] which can be used to determine whether the patient has diabetes insipidus as opposed to other causes of polydipsia (a condition of excessive thirst that causes an excessive intake of water). The patient is required, for a prolonged period, to forgo intake of water completely, to determine ...
Some conditions with polydipsia as a symptom are non-psychogenic (e.g., early Type 2 diabetes, primary hyperaldosteronism, and zinc deficiency, and some forms of diabetes insipidus). Primary polydipsia is a diagnosis of exclusion.
Diabetes insipidus (DI) is a condition characterized by large amounts of dilute urine and increased thirst. [1] The amount of urine produced can be nearly 20 liters per day. [ 1 ] Reduction of fluid has little effect on the concentration of the urine. [ 1 ]
Untreated central diabetes insipidus patients usually exhibit polyuria, nocturia, and polydipsia as a result of the initial rise of serum sodium and osmolality. [5] Patients may also experience neurologic symptoms associated with the underlying illness, such as headaches and diplopia, depending on the exact origin of the central diabetes insipidus.
Based on this clue, it soon came to light that there exist two types of hereditary diabetes insipidus. In 1947, the anti-diuretic hormone (ADH)-insensitive variety was termed nephrogenic diabetes insipidus (NDI), and attributed to a defect in the loop of Henle and the distal convoluted tubule. Since then, acquired forms of NDI have also been ...
Both cause excessive urination (hence the similarity in name), but whereas diabetes insipidus is a problem with the production of antidiuretic hormone (neurogenic diabetes insipidus) or the kidneys' response to antidiuretic hormone (nephrogenic diabetes insipidus), diabetes mellitus causes polyuria via osmotic diuresis, due to the high blood ...
Wolfram syndrome, also called DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness), is a rare autosomal-recessive genetic disorder that causes childhood-onset diabetes mellitus, optic atrophy, and deafness as well as various other possible disorders including neurodegeneration.
Patient education is a planned interactive learning process designed to support and enable expert patients [1] to manage their life with a disease and/or optimise their health and well-being. [ 2 ] [ 3 ]
