Shock triggered by a serious allergic reaction is known as anaphylactic shock, shock triggered by severe dehydration or blood loss is known as hypovolemic shock, shock caused by sepsis is known as septic shock, etc. Shock itself is a life-threatening condition as a result of compromised body circulation.

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.
Hypoxaemia. Blood with higher oxygen content appears bright red. Specialty. Pulmonology. Hypoxemia is an abnormally low level of oxygen in the blood. [1][2] More specifically, it is oxygen deficiency in arterial blood. [3] Hypoxemia has many causes, and often causes hypoxia as the blood is not supplying enough oxygen to the tissues of the body.
Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [1][2] It can be caused by severe dehydration or blood loss. [3][2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ failure.
Vasoconstriction is the narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels, in particular the large arteries and small arterioles. The process is the opposite of vasodilation, the widening of blood vessels. The process is particularly important in controlling hemorrhage and reducing acute blood loss.
Cardiogenic shock. Cardiogenic shock is a medical emergency resulting from inadequate blood flow to the body's organs due to the dysfunction of the heart. Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness. People may also have a severely low blood pressure and ...
Blood Tests: Most of the common cause of decreased flow of blood during the menses can be detected by blood tests. Tests for the level of hormones such as follicle-stimulating hormone, luteinizing hormone, estrogen, prolactin, insulin are important. In polycystic ovarian syndrome, there will be high levels of insulin and androgens.
Depends on underlying cause [2] Frequency. ~5 per 1,000 per year [1] Syncope, commonly known as fainting or passing out, is a loss of consciousness and muscle strength characterized by a fast onset, short duration, and spontaneous recovery. [1] It is caused by a decrease in blood flow to the brain, typically from low blood pressure. [1]
