What are the causes of hypoxemia?

Your current symptoms indicate hypoxia (oxygen deficiency) in the body, which may also be caused by anemia. Immediate oxygen therapy is required. Additionally, relevant diagnostic tests must be performed to identify the underlying cause before initiating targeted treatment. A complete blood count (CBC) is essential; if significant anemia is confirmed, symptomatic treatment with iron supplementation or other appropriate blood-building therapies will be sufficient to alleviate symptoms. However, if structural heart disease is suspected, further evaluation—such as echocardiography—will be necessary.
