what causes an increase in white blood cells?
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.
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)
868160
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.

A high white blood cell count could mean there is inflammation (swelling), which can be caused by rheumatoid arthritis (RA). However, infections, stress, and exercise will temporarily raise the white blood cell count, too. A CBC also measures hemoglobin, a component of red cells that contains iron and carries oxygen.

White blood cell count (WBC) A low WBC count may be due to chemotherapy, a viral infection, a toxic reaction, or a process in the bone marrow that limits the body's ability to make normal WBCs. A high WBC count may result from an infection or leukemia.
470960
Some conditions that can cause an increase in the monocytes in your blood are: viral infections, such as infectious mononucleosis, mumps, and measles. parasitic infections.
340973
Rarely, sepsis may result in neutropenia or in a leukemoid reaction. The white blood cell count may be increased or decreased because of an underlying medical condition such as cancer and/or associated treatment with chemotherapy and corticosteroids.
9533
A high white blood cell count usually indicates: An increased production of white blood cells to fight an infection. A reaction to a drug that increases white blood cell production. A disease of bone marrow, causing abnormally high production of white blood cells.
445928
Lymphocytosis is an increase in the number of lymphocytes in the bloodstream. It can be caused by certain hormones, stimulation of the immune system by infections, chronic diseases like arthritis, and leukemia, which is a cancer of the immune system.
276791
An elevated WBC count in itself is not usually dangerous, but the causes of it can be if left untreated. On average, your body is naturally designed to produce white blood cells when needed and reduce them when you have regained normal health.
784223
White blood cell count is increased in pregnancy with the lower limit of the reference range being typically 6,000/cumm. Leucocytosis, occurring during pregnancy is due to the physiologic stress induced by the pregnant state [8].
1222681
Certain respiratory illnesses, such as a whooping cough or tuberculosis, may cause the levels of white blood cells to increase. In some cases, all white blood cells are affected. However, some people have a specific disease in which only one type of white blood cell is affected.
49255
An increase of white blood cells indicates infection, inflammation, or bleeding into the cerebrospinal fluid. Some causes include: Abscess. Encephalitis. Hemorrhage.
68512
Increased white blood cells in urine may indicate: 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.
822533
Causes. Neutrophils are the primary white blood cells that respond to a bacterial infection, so the most common cause of neutrophilia is a bacterial infection, especially pyogenic infections. Neutrophils are also increased in any acute inflammation, so will be raised after a heart attack, other infarct or burns.

Neutropenia (noo-troe-PEE-nee-uh) occurs when you have too few neutrophils, a type of white blood cells. While all white blood cells help your body fight infections, neutrophils are important for fighting certain infections, especially those caused by bacteria.

White blood cell (WBC) count is elevated in obesity (1) and is a risk factor for atherosclerosis (2). An elevated WBC count is present in impaired glucose tolerance (IGT) (3), and WBC count is associated with macro- and microangiopathic complications in type 2 diabetes (4).
