The majority of fluid output occurs via the urine, approximately 1500 ml/day (approx 1.59 qt/day) in the normal adult resting state. [12] [13] Some fluid is lost through perspiration (part of the body's temperature control mechanism) and as water vapor in exhaled air. These are termed "insensible fluid losses" as they cannot be easily measured.
Premenstrual water retention (or premenstrual fluid retention) is the buildup of additional water or fluid in the body.This phenomenon can be seen in various forms like increasing weight gain and swollen belly, legs, or ankles.
Intracellular fluid refers to water that is contained within the cells. This consists of approximately 40% of the total body water. Fluid inside the cells has high concentrations of potassium, magnesium, phosphate, and proteins. [21] Extracellular fluid consists of all fluid outside of the cells, and it includes blood and interstitial fluid.
Edema (American English), also spelled oedema (British English), and also known as fluid retention, dropsy and hydropsy, is the build-up of fluid in the body's tissue, [1] a type of swelling. [4] Most commonly, the legs or arms are affected. [1] Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. [1]
The substances cause an increase in the osmotic pressure within the tubule, causing retention of water within the lumen, and thus reduces the reabsorption of water, increasing urine output (i.e., diuresis). The same effect can be seen in therapeutics such as mannitol, which is used to increase urine output and decrease extracellular fluid volume.
Fever or pyrexia in humans is a symptom of an anti-infection defense mechanism that appears with body temperature exceeding the normal range due to an increase in the body's temperature set point in the hypothalamus.
When Dr. Oz sat Rachael Ray down for a blood pressure test during a segment of her show, he wasn't entirely pleased with the numbers he saw. In fact, he made her do it again -- and he called her ...
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 ...
