54,200 (2015) [ 7] Iron-deficiency anemia is anemia caused by a lack of iron. [ 3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [ 3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [ 1]
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 ...
Iron-deficiency anemia is the most common type of anemia overall and it has many causes. RBCs often appear hypochromic (paler than usual) and microcytic (smaller than usual) when viewed with a microscope. Iron-deficiency anemia is due to insufficient dietary intake or absorption of iron to meet the body's needs. Infants, toddlers, and pregnant ...
Gastric antral vascular ectasia ( GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [ 1][ 2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [ 1] The dilated vessels result in intestinal bleeding. [ 3]
Frequency. 1 per 1000 people [8] Pernicious anemia is a disease where not enough red blood cells are produced due to a deficiency of vitamin B 12. [5] Those affected often have a gradual onset. [5] The most common initial symptoms are feeling tired and weak. [4]
Microcytic anaemia; Microcytosis is the presence of red cells that are smaller than normal. Normal adult red cell has a diameter of 7.2 µm. Microcytes are common seen in with hypochromia in iron-deficiency anaemia, thalassaemia trait, congenital sideroblastic anaemia and sometimes in anaemia of chronic diseases.
Specialty. Endocrinology. Latent iron deficiency ( LID ), also called iron-deficient erythropoiesis, [ 1] is a medical condition in which there is evidence of iron deficiency without anemia (normal hemoglobin level). [ 2] It is important to assess this condition because individuals with latent iron deficiency may develop iron-deficiency anemia.
Nutritional anemia can be caused by a lack of iron, protein, vitamin B12, and other vitamins and minerals that are needed for the formation of hemoglobin. However, Iron deficiency anemia is the most common nutritional disorder. [ 7] Signs of anemia include cyanosis, jaundice, and easy bruising. [ 7]
