[42M] Experiencing fatigue with low oxygen saturation

What might be happening

Based on the information you've provided, possible causes of your symptoms include:

• Chronic Fatigue Syndrome: This is a complex disorder characterized by extreme fatigue that can't be explained by any underlying medical condition. The fatigue worsens with physical or mental activity, but doesn't improve with rest.

  • There's no single test to confirm a diagnosis of chronic fatigue syndrome. You may need a variety of medical tests to rule out other health problems that have similar symptoms.

• Anemia: This is a condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues. Having anemia can make you feel tired and weak.

  • If you have anemia, your doctor might want to check your levels of vitamin B12, folate, and iron. They might also want to do a complete blood count (CBC) to see if your red blood cell count is lower than it should be.

• Sleep Apnea: This is a potentially serious sleep disorder in which breathing repeatedly stops and starts. This can lead to daytime fatigue.

  • To diagnose sleep apnea, your doctor may make an evaluation based on your signs and symptoms, an examination, and tests. A sleep study is usually needed to confirm the diagnosis.

• Heart Disease: Fatigue, lightheadedness, and lower than normal oxygen saturation could be signs of heart disease. Your heart may not be able to pump blood effectively, leading to a lack of oxygen in your body.

  • If heart disease is suspected, your doctor may recommend an electrocardiogram (ECG), echocardiogram, or other heart function tests.

What you can do

You should seek immediate medical attention. Your symptoms could be a sign of a serious condition that needs to be diagnosed and treated by a healthcare professional. In the meantime, try to rest and stay hydrated.
