The 11 most common signs of lack of oxygen in the blood

Illustrative photo

We all agree that oxygen is the most essential element of life on earth in general and human life in particular.

The fact that a person can live several weeks without food, several days without water, but only a few minutes without oxygen is enough to understand, these minutes are unfortunately measured with the fingers of one hand.

All the organs in our body rely on oxygen to produce energy. Without oxygen we would not be able to perform normal functions such as moving muscles, digesting food or thinking.

So oxygen keeps us alive, and our body needs blood oxygen saturation levels between 94% - 100%. These levels depend on the environment, past or present illnesses, lifestyle (habits), etc.

Below I am listing some of the signs and symptoms that indicate low levels of oxygen in the blood, which we doctors call hypoxemia:

1. Chronic, unjustified fatigue.

2. Brain fog.

3. Mild headache that gets worse.

4. Frequent, short breathing.

5. Dizziness.

6. Coughing.

7. Blurred vision.

8. Difficulty concentrating.

9. Mental confusion

10. Rapid heartbeat.

11. Cyanosis (bluish color in the skin, nails and lips)

If you have one or several of these symptoms consult a doctor.

Prolonged lack of oxygen in the blood can cause problems and irreversible consequences for your body.

Take care of yourself!
