Rare acquired causes of microcytic anemia include lead poisoning, zinc deficiency, copper deficiency, alcohol, and certain medications. [3] Other causes that are typically thought of as causing normocytic anemia or macrocytic anemia must also be considered, as the presence of two or more causes of anemia can distort the typical picture.
Plummer–Vinson syndrome (also known as Paterson–Kelly syndrome [1] or Paterson–Brown-Kelly syndrome in the UK [2]) is a rare disease characterized by dysphagia (difficulty swallowing), iron-deficiency anemia, glossitis (inflammation of the tongue), cheilosis (cracking at the corners of the mouth), and esophageal webs (thin membranes in the esophagus that can cause obstruction).

A blood smear showing hypochromic (and microcytic) anemia. Note the increased central pallor of the red blood cells. Hypochromic anemia is a generic term for any type of anemia in which the red blood cells are paler than normal. (Hypo- refers to less, and chromic means colour.) A normal red blood cell has a biconcave disk shape and will have an ...
Red blood cells normally survive an average of about 120 days, becoming damaged (their oxygen-carrying capacity becomes compromised) as they age.
The normochromic cells have a normal concentration of haemoglobin, and are therefore 'red enough' while the hypochromic cells do not; thus the value of the mean corpuscular hemoglobin concentration.The most common cause of microcytosis is iron deficiency anemia. Every time Hb synthesis being impaired in bone marrow microcytosis can occurs such ...
Pernicious anemia is the most common cause of clinically evident vitamin B 12 deficiency worldwide. [14] Pernicious anemia due to autoimmune problems occurs in about one per 1000 people in the US. Among those over the age of 60, about 2% have the condition. [8] It more commonly affects people of northern European descent. [2]
Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
The most important measure is prevention – avoidance of the drugs and foods that cause hemolysis. Vaccination against some common pathogens (e.g. hepatitis A and hepatitis B) may prevent infection-induced attacks. [26] In the acute phase of hemolysis, blood transfusions might be necessary, or even dialysis in acute kidney failure. Blood ...
