What Do Blue Fingernails Mean?
By
Bluish color to your fingernails may be a sign of a lack of oxygen in your blood, due to coldness or possible disease. If normal color returns by warming your fingers or through massage, then the bluish color is due to cold. If not, then it could be due to several possible diseases.
- Asthma
- Pneumonia
- Emphysema
- Raynaud’s Phenomenon
- Carbon Monoxide Poisoning
- COPD (Chronic Obstructive Pulmonary Disease)
- Adult Respiratory Distress Syndrome
A simple non-invasive test by your doctor can be done to measure the oxygenation of your blood or more advance blood gases test can help determine the contributing factors to your blue fingernails.
If breathing difficulties are present, call 9-1-1 immediately. Otherwise see your physician soon to determine the underlying factors and a course of treatment.
