Types and causes

DEFINITION OF Diuresis isnt simply " production of urine by kidney" ; but is " Production of ABNORMALLY large amount of urine by kidney."

The kidney produces up to 250 L of "prourine" per day, but reabsorbs most before it reaches the bladder. In the anatomy of mammals, the urinary bladder is the organ that collects urine excreted by the kidneys prior to disposal by urination. ...

Polyuria is increased diuresis. This may be due to large fluid intake, various illnesses (diabetes insipidus, osmotic diuresis due to diabetes mellitus or hypercalcemia) or various chemical substances (diuretics, caffeine, alcohol). It may also occur after supraventricular tachycardias, childbirth, and the removal of an obstruction within the urinary tract. Diuresis is restrained by antidiuretics such as ADH, angiotensin II and aldosterone. Polyuria is the passage of a large volume of urine in a given period. ... Diabetes insipidus (DI) is a disease characterized by excretion of large amounts of severely diluted urine, which cannot be reduced when fluid intake is reduced. ... For the disease characterized by excretion of large amounts of severely diluted urine, see diabetes insipidus. ... Hypercalcaemia is an elevated calcium level in the blood. ... A diuretic is any drug that elevates the rate of bodily urine excretion. ... For other uses, see Caffeine (disambiguation). ... In chemistry, an alcohol is any organic compound in which a hydroxyl group (-OH) is bound to a carbon atom of an alkyl or substituted alkyl group. ... A supraventricular tachycardia (SVT) is a rapid rhythm of the heart in which the origin of the electrical signal is either the atria or the AV node. ... Childbirth (also called labo(u)r, birth, partus or parturition) is the culmination of a human pregnancy with the emergence of a newborn infant from its mothers uterus. ... The urinary system is a system of organs, tubes, muscles, and nerves that work together to create, store, and carry, urine. ... Antidiuretic hormone (ADH), or arginine vasopressin (AVP), is a peptide hormone produced by the hypothalamus, and stored in the posterior part of the pituitary gland. ... Angiotensinogen, angiotensin I and angiotensin II are peptides involved in maintenance of blood volume and pressure. ... Aldosterone is a steroid hormone synthesized from cholesterol by the enzyme aldosterone synthase. ...

Cold diuresis is the occurrence of increased urine production on exposure to cold.

Substances that increase diuresis are called diuretics. Coffee is an example of a proposed diuretic. A diuretic is any drug that tends to increase the flow of urine from the body (diuresis). ... Coffee Coffee is a beverage, served hot or with ice, prepared from the roasted seeds of the coffee plant. ...

Substances that decrease diuresis allow more vasopressin or antidiuretic hormone (ADH) to be present in the kidney. Arginine vasopressin (AVP), also known as argipressin or antidiuretic hormone (ADH), is a human hormone that is mainly released when the body is low on water; it causes the kidneys to conserve water by concentrating the urine and reducing urine volume. ...

High-altitude diuresis occurs at altitudes above 10,000 ft and is a desirable indicator of adaptation to high altitudes. Mountaineers who are adapting well to high altitudes experience this type of diuresis. Urine output is thus an important indicator of adaptation to altitude (or lack thereof). Persons who produce less urine even in the presence of adequate fluid intake probably are not adapting well to altitude (Hackett 1980; pp. 54, 62).
