what happens when you have too much red blood cells?

If you have polycythemia, your bone marrow makes too many red blood cells. This causes your blood to thicken and flow more slowly, putting you at risk for blood clots that can cause heart attacks or strokes. There is no known cure.

High Hgb is known as polycythemia. This means you have too many red blood cells. Polycythemia vera is a cancer of the blood in which your bone marrow overproduces red blood cells. With polycythemia, a blood test also shows that you have a high red blood cell count and high hematocrit.

Medical conditions that can cause high hemoglobin levels include: Polycythemia vera (the bone marrow produces too many red blood cells) Lung diseases such as COPD, emphysema or pulmonary fibrosis (lung tissue becomes scarred) Heart disease, especially congenital heart disease (the baby is born with it)

Polycythemia is a condition that results in an increased level of circulating red blood cells in the bloodstream. People with polycythemia have an increase in hematocrit, hemoglobin, or red blood cell count above the normal limits.

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.

In this case, it can occur if your body absorbs too much iron from the blood you drink. Reaching this level of toxicity can increase your risk of developing other life-threatening disorders, including heart disease, liver disease, and diabetes.

When the hemoglobin level is low, the patient has anemia. An erythrocytosis is the consequence of too many red cells; this results in hemoglobin levels above normal. The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma).

However, a varied size distribution of red blood cells is a hallmark of iron deficiency anemia, and as such shows an increased RDW in virtually all cases. In the case of both iron and B12 deficiencies, there will normally be a mix of both large cells and small cells, causing the RDW to be elevated.

Blood cells, being mostly saline, would draw water, causing them to expand rapidly to the point of cell membrane rupture. This would result in the contents of the cells spilling into the plasma. Extensive damage to a large percentage of body cells may result in death.

One of the affected organs is the liver. Sickle cell disease and its treatment through blood transfusion can lead to significant liver damage. This disease also can cause the liver to regrow abnormally after damage. This can cause high blood pressure in the liver.

If you have a high RBC count, you could experience symptoms such as: fatigue. shortness of breath. joint pain.

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.

Leukemia. Leukemia itself can also cause anemia. As leukemia blood cells multiply rapidly, little room is left for normal red blood cells to develop. If your red blood cell counts drop too low, anemia can occur.

Diseases and conditions that cause your body to produce fewer red blood cells than normal include: Aplastic anemia. Cancer. Certain medications, such as antiretroviral drugs for HIV infection and chemotherapy drugs for cancer and other conditions.

Excessive or prolonged menstrual bleeding can lead to other medical conditions, including: Anemia. Menorrhagia can cause blood loss anemia by reducing the number of circulating red blood cells.

What is polycythemia vera (PV)? PV is a blood disorder in which the body makes too many red blood cells. These extra red cells make blood thicker than normal. The thickened blood flows slower and may clot within your body. Red blood cells carry oxygen to organs and tissues throughout the body.

Polycythemia vera (pol-e-sy-THEE-me-uh VEER-uh) is a type of blood cancer. It causes your bone marrow to make too many red blood cells. These excess cells thicken your blood, slowing its flow, which may cause serious problems, such as blood clots. Polycythemia vera is rare.
