In addition to the myoglobinuria, two other mechanisms contribute to kidney impairment: low blood pressure leads to constriction of the blood vessels and therefore a relative lack of blood flow to the kidney, and finally uric acid may form crystals in the tubules of the kidneys, causing obstruction.
The increased acid concentration allows the iron from the aggregate protein to be released into the surrounding renal tissue. [13] Iron then strips away molecular bonds of the surrounding tissue which eventually will lead to kidney failure if the tissue damage is too great.

Kidney ischemia is a loss of blood flow to the kidney cells. Several physical symptoms include shrinkage of one or both kidneys, [19] renovascular hypertension, [20] acute renal failure, [19] progressive azotemia, [19] and acute pulmonary edema. [19] It is a disease with high mortality rate and high morbidity. [21]
Exercise-associated hyponatremia (EAH) is a fluid-electrolyte disorder caused by a decrease in sodium levels (hyponatremia) during or up to 24 hours after prolonged physical activity. [1] This disorder can develop when marathon runners or endurance event athletes drink more fluid, usually water or sports drinks, than their kidneys can excrete ...
Hyponatremia occurs 1) when the hypothalamic-kidney feedback loop is overwhelmed by increased fluid intake, 2) the feedback loop malfunctions such that ADH is always "turned on", 3) the receptors in the kidney are always "open" regardless of there being no signal from ADH to be open; or 4) there is an increased ADH even though there is no ...
During exercise increased flow to the working muscles is often balanced by reduced flow to other tissues, such as kidneys, spleen, and liver. [5] Blood flow to the muscles is lower in cold water, but exercise keeps the muscle warm and flow elevated even when the skin is chilled. Blood flow to fat normally increases during exercise, but this is ...
Ischemia, meaning insufficient blood flow to a tissue, can also result in hypoxia in the affected tissues. This is called 'ischemic hypoxia'. Ischemia can be caused by an embolism, a heart attack that decreases overall blood flow, trauma to a tissue that results in damage reducing perfusion, and a variety of other causes.
The kidney’s job is to regulate what’s in the blood, things like removing waste, making sure electrolyte levels are steady, regulating the overall amount of water, and even making hormones - the kidneys do a lot! Blood gets into the kidney through the renal artery, into tiny clumps of arterioles called glomeruli where it is initially ...
