Low oxygen headaches can feel like a pressure or tightness in the head, similar to a tension headache. It can also feel like a throbbing or pulsing sensation. Some people may also experience other symptoms, such as dizziness, confusion, nausea, or shortness of breath. In severe cases, low oxygen headaches can be accompanied by changes in vision, loss of consciousness, or chest pain.
Causes of Low Oxygen Headaches
Low oxygen headaches are usually caused by a decrease in the amount of oxygen reaching the brain. This can be due to a number of factors, such as high altitude, sleep apnea, anemia, or heart or lung conditions. Some medications, such as those used to treat high blood pressure or asthma, can also cause a decrease in oxygen levels in the blood.
Diagnosis of Low Oxygen Headaches
If you experience a low oxygen headache, it is important to seek medical attention. Your doctor will ask questions about your symptoms and medical history, and may order tests to determine the cause. These tests may include a physical exam, blood tests, a CT scan, or an MRI.
Treatment of Low Oxygen Headaches
Treatment for low oxygen headaches depends on the underlying cause. If the cause is high altitude, you may need to reduce your altitude and rest. If the cause is a medical condition, such as anemia or sleep apnea, your doctor may prescribe medications or recommend lifestyle changes. In some cases, oxygen therapy may be necessary.
