'''Heinz body anemia''' is a form of [[hemolytic anemia]] characterized by the presence of [[Heinz bodies]] in [[red blood cells]].

This can occur due to various factors, including:
			* [[Glucose-6-phosphate dehydrogenase deficiency]] (G6PD deficiency)

			In Heinz body anemia, oxidative damage leads to the denaturation of hemoglobin, which precipitates and forms Heinz bodies. These inclusions are recognized by the [[reticuloendothelial system]], particularly the [[spleen]], leading to the premature destruction of affected red blood cells, a process known as [[extravascular hemolysis]].

'''Heinz bodies''' are inclusions within red blood cells composed of denatured hemoglobin. They are named after the German physician Robert Heinz, who first described them in 1890.

Heinz bodies form when hemoglobin is exposed to oxidative stress, which can be caused by various factors such as certain drugs, toxins, or underlying medical conditions. The oxidative stress leads to the denaturation of hemoglobin, causing it to precipitate and form inclusions within the red blood cell.
