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 accumulation in the tissues and organs results in a corresponding iron deficiency in the blood, leading to anemia. Anemia and diabetes usually occur by the time an affected person is in his or her twenties. [4] Affected individuals also experience retinal degeneration caused by excess iron.
Autoimmune diseases that affect the GI tract “can prevent a person from absorbing iron from the foods that they eat, even if they're eating iron-rich foods,” says Dr. Danielle Nance, a ...
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.
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 malabsorption is a less common cause of iron-deficiency anemia, but many gastrointestinal disorders can reduce the body's ability to absorb iron. [39] There are different mechanisms that may be present. In coeliac disease, abnormal changes in the structure of the duodenum can decrease iron absorption. [40]
[1] [5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle swelling) and/or symptoms related to the tachycardia or arrhythmia (e.g. palpitations). [1] [2] Though atrial fibrillation is the most common cause of TIC, several tachycardias and arrhythmias have been associated with the disease. [5] [1]
Postural orthostatic tachycardia syndrome (POTS) is a disorder of the autonomic nervous system, which controls body functions we often don’t think about, such as heart rate and blood pressure.
