Tissue hypoxia (oxygen deficiency) occurs when the blood vessels in the hands, feet, and other extremities narrow in response to cold
Erythropoietin is secreted in response to hypoxia. It produces a negative feedback loop that raises the oxygen concentration of the blood. Also called EPO, erythropoietin, is a glycoprotein hormone that controls red blood cell production.

Hypoxia can occur in healthy people when they ascend to high altitudes.
This deficiency is called hypoxia or hypoxemia.This deficiency is called hypoxia or hypoxemia.

Oxygen relieves hypoxia.
Hypoxia can be treated with oxygen therapy
Erythropoietin triggers more red blood cells to be produced in the bone marrow. Red blood cells carry oxygen throughout the body, therefore if there are more red blood cells than more oxygen can be exchanged throughout the body decreasing lack of oxygen (hypoxia). So in hypoxia the kidneys produce and increased amount of erythropoietin.

Hypoxia means lack of adequate oxygenation. The consequence of sustained hypoxia is, eventually, cellular death, followed by death of the entire organism.
Fish can get hypoxia from nitrogen based fertilizer runoff in the water.
