Hyperhidrosis is a medical condition in which a person exhibits excessive sweating, [1] [2] more than is required for the regulation of body temperature. [3] Although it is primarily a physical burden, hyperhidrosis can deteriorate the quality of life of the people who are affected from a psychological, emotional, and social perspective. [4]
Hematidrosis is a condition in which capillary blood vessels that feed the sweat glands rupture, causing them to exude blood, occurring under conditions of extreme physical or emotional stress. [4] Severe mental anxiety activates the sympathetic nervous system to invoke the fight-or-flight response to such a degree as to cause hemorrhage of the ...
Hemodialysis, also spelled haemodialysis, or simply dialysis, is a process of filtering the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure.
The dialyzer clearance K is usually estimated, based on the urea transfer ability of the dialyzer (a function of its size and membrane permeability), the blood flow rate, and the dialysate flow rate. [4] In some dialysis machines, the urea clearance during dialysis is estimated by testing the ability of the dialyzer to remove a small salt load ...
Ahead, one beauty editor's experience with using Xeomin/Botox to curb excessive underarm sweating—plus how it works, what it costs, and how long it lasts.
Measurements of urea and creatinine (Cr) in the blood are used to assess renal function. For historical reasons, the lab test measuring urea is known as "blood urea nitrogen" (BUN) in the US. The BUN:Cr ratio is a useful measure in determining the type of azotemia and will be discussed in each section below. A normal BUN:Cr is equal to 15. [3]
On the other hand, a fit person will start sweating earlier and more readily. As someone becomes fit, the body becomes more efficient at regulating the body's temperature and sweat glands adapt along with the body's other systems. [23] Human sweat is not pure water; though it contains no protein, it always contains a small amount (0.2–1%) of ...
When environmental temperature is above core body temperature, sweating is the only physiological way for humans to lose heat. [10] Arteriolar vasodilation occurs. The smooth muscle walls of the arterioles relax allowing increased blood flow through the artery. This redirects blood into the superficial capillaries in the skin increasing heat ...
