what is the cause for high red blood cell count?
3842
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)

Cancer: Lung, stomach, breast, and ovarian cancers, as well as lymphoma, can cause high platelet counts. Additional blood testing, imaging scans, or a biopsy can test for cancer. Anemia: People with iron-deficiency or hemolytic anemia may have high platelets. Further blood testing can detect most forms of anemia.

Blood tests For example, if the lymphoma invades the bone marrow (where new blood cells are made) a person might have anemia (not enough red blood cells). A high white blood cell count is another possible sign of HL, although it can also be caused by infection.

White blood cells and platelets are usually high in sickle cell disease. Too many white blood cells (WBCs) and platelets can cause damage to the blood vessels. Also, high WBCs and platelets are associated with more severe complications of sickle cell disease such as stroke and acute chest syndrome.

['A bacterial urinary tract infection. This is the most common cause of a high white blood cell count in urine.', 'Inflammation of the urinary tract or kidneys.']
713184
The following conditions can cause white blood cell counts to be high: Viral or bacterial infection. Inflammation. Excessive physical or emotional stress (such as fever, injury, or surgery)
20232
The main causes of elevated white blood cells include: To fight a viral, fungal, bacterial, or parasitic infection. A negative reaction to a drug that triggers an immune and white blood cell response. Disease or malfunction that causes the bone marrow to overproduce white blood cells.
641766
Decreased red blood cell production may be caused by primary bone marrow diseases (such as aplastic anemia or hematopoietic malignancy), kidney failure, toxins, or drugs such as phenylbutazone. Longterm debilitating diseases may also be associated with mild anemia.

Thick blood is caused by heavy proteins, or by too much blood in the circulation. Too many red cells, white cells, and platelets will result in blood thickening. Another cause is an imbalance in the blood clotting system.
1146980
Red blood cells may be destroyed due to: An autoimmune problem in which the immune system mistakenly sees your own red blood cells as foreign substances and destroys them. Genetic defects within the red cells (such as sickle cell anemia, thalassemia, and G6PD deficiency)

High red blood cell count. A significant increase in the number of red blood cells thickens the blood and makes clots more likely. This raises the risk for stroke.

The reticulocyte count rises when there is a lot of blood loss or in certain diseases in which red blood cells are destroyed prematurely, such as hemolytic anemia. Also, being at high altitudes may cause reticulocyte counts to rise, to help you adjust to the lower oxygen levels at high altitudes.

A white blood cell count that's super-high often indicates leukemia — cancer of the bone marrow. The bone marrow produces all blood cells, not just white ones but also red ones and platelets. But the malignancy causes the marrow to produce too many of the white variety.
886604
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).
536250
Certain medications also can cause white blood cell counts to drop. If your white blood cell count is higher than normal, you may have an infection or inflammation. Or, it could indicate that you have an immune system disorder or a bone marrow disease. A high white blood cell count can also be a reaction to medication.

More serious conditions that may cause high white blood cell counts include blood disorders, including: Leukemia. Lymphoma. Bone marrow disorders such as polycythemia vera or myelofibrosis.
