what causes increased red blood cell production?

Medical conditions that can cause an increase in red blood cells include: Heart failure, causing low blood oxygen levels. Congenital heart disease (born with it) Polycythemia vera (a blood disorder in which the bone marrow produces too many red blood cells)
363338
An increase of white blood cells indicates infection, inflammation, or bleeding into the cerebrospinal fluid. Some causes include: Abscess. Encephalitis.

Anemia and thrombocytopenia have been found in patients with acute and chronic renal failure. Red cell production is stimulated by erythropoietin (EPO), and the kidney is the source to secrete EPO. In patients with chronic renal failure, deficiency in EPO production is the main cause of the development of anemia.

However, when tissues are damaged by injury or disease, they release more LDH into the bloodstream. Conditions that can cause increased LDH in the blood include liver disease, heart attack, anemia, muscle trauma, bone fractures, cancers, and infections such as meningitis, encephalitis, and HIV.

Several mechanisms contribute to acute reduction in hemoglobin levels in the setting of sepsis, including reduced production of red blood cells induced by the systemic inflammatory response, as well as increased destruction of red cells due to hemolysis and bleeding.

The amount of hemoglobin increases proportionately with the increase in cell size. Therefore, if the increase in MCV is not related to macrocytic anemia, the mean cell hemoglobin concentration (MCHC) also increases in proportion.

In conditions where the rate of RBC breakdown is increased, the body initially compensates by producing more RBCs; however, breakdown of RBCs can exceed the rate that the body can make RBCs, and so anemia can develop. Bilirubin, a breakdown product of hemoglobin, can accumulate in the blood, causing jaundice.

Iron supplements taken by mouth begin increasing the body's production of red blood cells within three to 10 days. Iron usually needs to be taken for many months to bring the levels back to normal.

In addition to erythropoietin, red blood cell production requires adequate supplies of substrates, mainly iron, vitamin B12, folate, and heme. RBCs survive about 120 days. They then lose their cell membranes and are then largely cleared from the circulation by the phagocytic cells of the spleen and liver.

Eating an iron-rich diet can increase your body's production of RBCs. Iron-rich foods include: red meat, such as beef. organ meat, such as kidney and liver.
135521
Your body may increase red blood cell production to compensate for any condition that results in low oxygen levels, including: Heart disease (such as congenital heart disease in adults) Heart failure. A condition present at birth that reduces the oxygen-carrying capacity of red blood cells (hemoglobinopathy)

The disease process itself can sometimes interfere with the normal production of red cells, white cells and platelets in the bone marrow. For example, almost all patients with leukemia (which primarily affects the marrow and blood) require some transfusions during their care.
86724
The main causes of bone marrow suppression that result in decreased red blood cell production include: any severe, chronic (long-lasting) disease (such as chronic kidney or liver disease, Ehrlichia) very poor nutrition or nutritional imbalances. autoimmune disease.

Red Blood Cell Disorders Men have slightly higher levels of hemoglobin, and this is thought to be due to the stimulatory effect of androgens on the bone marrow.

Thrombocytosis (High Platelets) High blood platelet counts can be caused by several conditions, including anemia, cancer, inflammation and infection. Treatment usually focuses on the underlying condition or disease. Essential thrombocythemia (ET) is a rare disease in which the bone marrow produces too many platelets.

Chronic high altitude hypoxia leads to an increase in red cell numbers and hemoglobin concentration. Previous studies have shown that permanent high altitude residents possess elevated hemoglobin levels and hematocrit values (Leon-Velarde et al., 2000).
