Frequent question: Can sleep apnea affect blood counts?

How Sleep Apnea Affects Red Blood Cells. One study presented a correlation among sleep apnea in which patients diagnosed with the sleep disorder had higher red blood cell counts. Elevated hematocrit indicates a shortage of oxygen in the patient’s system.

Does sleep apnea show up in blood work?

As obstructive sleep apnea (OSA) can be a possible cause of elevated red blood cell count, Ojile says primary care physicians should consider referring these patients for evaluation for OSA. A simple blood test administered by physicians can measure complete blood count.

Can sleep apnea cause low red blood cells?

And as oxygen falls, your body has two main ways to compensate: (1) take in more air—not usually possible if you have sleep apnea; (2) make more red blood cells to carry more oxygen and/or concentrate the red blood cells by decreasing the other elements that make up your blood.

Does lack of sleep affect white blood cell count?

Decreased immune function and greater risk for illness.

Some animal and human studies have shown that lack of sleep appears to lower white blood cell count, which is an indication of decreased immune function. This means you may be more susceptible to illnesses when you are sleep deprived.

Does lack of sleep affect blood test results?

This way, they identified 68 genes whose expression was affected by lack of sleep. They were able to find out with 92 percent accuracy whether the blood samples came from a person who was sleep deprived or who, to the contrary, had had enough rest.

How does sleep apnea cause polycythemia?

Secondary polycythemia is characterized by increased erythropoiesis stimulating factor (EPO), being normal erythrocyte precursors in the bone marrow. The obstructive sleep apnea syndrome (OSAS) is characterized by intermittent hypoxia occur during sleep and can cause secondary polycythemia.

Does sleep apnea cause elevated hemoglobin?
