8 Warning Signs of Low Blood Oxygen Levels
Oxygen is essential for the body’s cells and organs to function properly. When blood oxygen levels drop below the normal range — typically below 95% — your body can begin to suffer from a lack of oxygen, a condition known as hypoxemia. If left untreated, low blood oxygen can lead to severe complications, including organ damage or respiratory failure. Recognizing the early warning signs is crucial to ensure timely medical attention.
