Main symptoms that may appear in anemia [20] The hand of a person with severe anemia (on the left, with ring) compared to one without (on the right). A person with anemia may not have any symptoms, depending on the underlying cause, and no symptoms may be noticed, as the anemia is initially mild, and then the symptoms become worse as the anemia worsens.
An analysis of data from more than 8,000 adults in the U.S. revealed that 14% had low iron blood levels, a condition known as absolute iron deficiency, while 15% had the right iron levels but ...
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]
Stage 3 – Anemia (reduced hemoglobin levels) is present but red blood cell appearance remains normal. [4] Stage 4 – Changes in the appearance of red blood cells are the hallmark of this stage; first microcytosis and then hypochromia develop. [4] Stage 5 – Iron deficiency begins to affect tissues, manifesting as symptoms and signs. [4]
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 ...
Pernicious anemia is the most common cause of vitamin B 12 deficiency anemia in adults, which results from malabsorption of vitamin B 12 due to a lack or loss of intrinsic factor. [ 2 ] [ 8 ] There are relatively few studies which have assessed the impact of haematological measures in response to B 12 supplementation.
Iron poisoning can occur when doses of 20 to 60 mg/kg or more of elemental iron is ingested with most cases reporting primarily gastrointestinal symptoms. [4] Systemic signs and symptoms shown in serious toxicity occur at higher doses exceeding 60 mg/kg. [5] Ingesting above 120 mg/kg may be fatal. [4]
Treatment depends on the type and cause of the hemolytic anemia. [2] Symptoms of hemolytic anemia are similar to other forms of anemia (fatigue and shortness of breath), but in addition, the breakdown of red cells leads to jaundice and increases the risk of particular long-term complications, such as gallstones [4] and pulmonary hypertension.
