Reason for low hematocrit and hemoglobin

If the anemia come on quickly, the symptoms often may include, feeling like one is going to pass out, confusion, chest pain, and increased thirstВ вЂ“ but if the anemia continues slowly (chronic), the body may adapt and compensate for this change in this case, no symptoms may appear until the anemia becomes more severe. A patient with anemia may report feeling tired, weak, decreased ability to concentrate, and sometimes shortness of breath on exertion. 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. The hand of a person with severe anemia (on the left, with ring) compared to one without (on the right)ДЄnemia is considered to be the most common blood disorder. Efforts to reach global targets contribute to reaching Sustainable Development Goals (SDGs), with anemia as one of the targets in SDG 2 for achieving zero world hunger. ДЄnemia is one of the six WHO global nutrition targets for 2025 and for diet-related global targets endorsed by World Health Assembly in 20. The name is derived from Ancient Greek: бјЂОЅО±О№ОјОЇО± anaimia, meaning 'lack of blood', from бјЂОЅ- an-, 'not' and О±бј·ОјО± haima, 'blood'. This condition is most prevalent in children with also an above average prevalence in elderly and women of reproductive age (especially during pregnancy). In 2013, anemia due to iron deficiency resulted in about 183,000 deaths вЂ“ down from 213,000 deaths in 1990.

Iron-deficiency anemia affects nearly 1 billion people. ДЄnemia is the most common blood disorder, affecting about a third of the global population. Erythropoiesis-stimulating agents are only recommended in those with severe anemia. These recommendations may also apply to some people with acute bleeding. In those without symptoms, they are not recommended unless hemoglobin levels are less than 60 to 80В g/L (6 to 8В g/dL). The use of blood transfusions is typically based on a person's signs and symptoms. Dietary supplementation, without determining the specific cause, is not recommended. Д¬ertain groups of individuals, such as pregnant women, benefit from the use of iron pills for prevention. These include many with reduced limb loading, such as spinal cord injured patients, astronauts, elderly people with limited mobility, bed-bound and experimental bed-rest subjects. ДЄ large number of patients diagnosed with anemia of chronic disease present with no active inflammation or dietary issues. Further testing is then required to determine the cause. The diagnosis of anemia in men is based on a hemoglobin of less than 130 to 140В g/L (13 to 14В g/dL) in women, it is less than 120 to 130В g/L (12 to 13В g/dL). If the cells are small, it is called microcytic anemia if they are large, it is called macrocytic anemia and if they are normal sized, it is called normocytic anemia.

ДЄnemia can also be classified based on the size of the red blood cells and amount of hemoglobin in each cell. Causes of increased breakdown include genetic disorders such as sickle cell anemia, infections such as malaria, and certain autoimmune diseases. Causes of decreased production include iron deficiency, vitamin B12 deficiency, thalassemia and a number of bone marrow tumors. Causes of bleeding include trauma and gastrointestinal bleeding. ДЄnemia can be caused by blood loss, decreased red blood cell production, and increased red blood cell breakdown. Anemia can be temporary or long term and can range from mild to severe. Preoperative anemia can increase the risk of needing a blood transfusion following surgery. Additional symptoms may occur depending on the underlying cause. Anemia must be significant before a person becomes noticeably pale. When the anemia is acute, symptoms may include:confusion, feeling faint, loss of consciousness, and increased thirst.

When anemia comes on slowly, the symptoms are often vague, such as tiredness, weakness, shortness of breath, headaches, and a reduced ability to exercise.

Tiredness, pale skin, weakness, shortness of breath, feeling faint Д«lood loss, decreased red blood cell production, increased red blood cell breakdown ДЄnemia or anaemia ( British English) is a blood disorder in which the blood has a reduced ability to carry oxygen due to a lower than normal number of red blood cells, or a reduction in the amount of hemoglobin.
