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 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]
The Bristol stool scale is a medical aid designed to classify the form of human feces into seven categories. Sometimes referred to in the UK as the Meyers Scale, it was developed by K.W. Heaton at the University of Bristol and was first published in the Scandinavian Journal of Gastroenterology in 1997. [4]
Barium isn’t absorbed at all by the body, and what many people don’t realize is how common it is to pass pale, chalky, and/or clay-like stool for several days after swallowing barium. “It ...
Anemia or anaemia (British English) is a blood disorder in which the blood has a reduced ability to carry oxygen.This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function.
The therapeutic dose for iron deficiency anemia is 3–6 mg/kg/day. Individuals who have ingested less than 20 mg/kg of elemental iron typically do not exhibit symptoms. [4] It is unlikely to get iron poisoning from diet alone with iron supplements being the cause of overdose.
It is estimated that 90% of people experience rectal bleeding (of varying severity), 90% experience watery or loose stools with increased stool frequency (diarrhea), and 75-90% of people experience bowel urgency. [13] Additional symptoms may include fecal incontinence, mucous rectal discharge, and nocturnal defecations. [12]
Since iron stores in the body are generally depleted, and there is a limit to what the body can process (about 2–6 mg/kg of body mass per day; i.e. for a 100 kg/220 lb man this is equal to a maximum dose of 200–600 mg/per day) without iron poisoning, this is a chronic therapy which may take 3–6 months.
