what happens when you have low white blood cells?
218736
White blood cells are produced by your bone marrow to help your body fight infection. If you have fewer than normal white blood cells, you have a higher risk of getting an infection. When you have a low white blood cell count, your immune system isn't working as well as it should.

As CLL becomes more advanced, the cancer cells can replace the bone marrow's normal blood-making cells, which can cause the marrow to produce fewer red cells, white cells and platelets with these results: A low number of red blood cells ( anemia ) can lead to feeling very tired, shortness of breath and pale skin.

White Blood Cells (also called leukocytes) White blood cells protect the body from infection. They are much fewer in number than red blood cells, accounting for about 1 percent of your blood.

Neutropenia. Neutropenia (noo-troe-PEE-nee-uh) is a low number of neutrophils, a type of white blood cell that fights infections of fungi and bacteria. Neutropenia can be caused by cancer or by diseases, disorders or infections that damage bone marrow.

Why It Occurs. A person with cancer can develop a low WBC count from the cancer or from treatment for the cancer. Cancer may be in the bone marrow, causing fewer neutrophils to be made. The WBC count can also go down when cancer is treated with chemotherapy drugs, which slow bone marrow production of healthy WBCs.

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.

An elevated number of white blood cells is called leucocytosis. This can result from bacterial infections, inflammation, leukaemia and other blood disorders, trauma, medication, or post-operatively. A WBC count of 11.0–17.0x109/L cells would be considered mild to moderate leucocytosis.

['weakness and fatigue due to shortage of red blood cells (anemia)', 'bleeding and bruising due to low blood platelets (thrombocytopenia)', 'infections due to shortage of normal white blood cells (leukopenia)', 'extreme thirst.', 'frequent urination.', 'dehydration.', 'abdominal pain.', 'loss of appetite.']

Having a higher or lower number of WBCs than normal may indicate an underlying condition. A WBC count can detect hidden infections within your body and alert doctors to undiagnosed medical conditions, such as autoimmune diseases, immune deficiencies, and blood disorders.

What if you had no white blood cells? If you had no white cells, you would get lots of very serious infections. White blood cells can find germs that enter your body and destroy them, which keeps them from making you sick.

A high white blood cell count alone doesn't cause any symptoms. The symptoms you feel may come from the medical problem that your white blood cells are fighting. For example, if you have pneumonia, you may have a fever and trouble breathing.

Having a low red blood count or anemia can cause symptoms that may include: fatigue. dizziness. shortness of breath.

A low red blood cell count is called anemia. If you have a low red blood cell count, you may: Feel a little tired or very tired.

The definition of low white blood cell count varies from one medical practice to another. In general, for adults a count lower than 4,000 white blood cells per microliter of blood is considered a low white blood cell count. For children, that threshold varies with age.

White blood cells work to destroy any foreign virus, fungus, or bacteria that enter your body. When you get sick, your white blood cell count is higher than normal. This is because your body is releasing more of these cells to fight the infection.

If you have a low white blood cell count, your doctor can prescribe medicines to help stimulate your immune system after each round of chemotherapy. Your doctor also may decide to stop your chemotherapy treatment for a little while so your body can recover and make more white blood cells.
