What Causes Blue Fingernails?
Blue nails can be a reason to worry and are sometimes a symptom of a disease. It is the matter that the cause is found for the appropriate treatment to be.
1. Lack of Oxygen in the Blood
The main reason for blue fingernails and toenails is a lack of oxygen in the blood, also known as cyanosis. This is due to your heart, lungs, or blood circulation not functioning correctly. Possible causes might include:
- Heart conditions: Congenital heart defects, heart failure, or other cardiovascular issues can decrease the oxygen level of your blood.
- Lung diseases: Diseases like COPD (Chronic Obstructive Pulmonary Disease), asthma or pneumonia might result in the lungs being less effective to transfer oxygen.
- Cold exposure: In colder climates like Canada, low temperatures exposure can lead to your blood vessels constricting and this can be the reason for blood and oxygen not coming to your extremities in the required amounts temporarily.
2. Raynaud’s Disease
Raynaud’s disease is another possible cause of blue fingernails and toenails. This case is identified by the narrowing of the blood vessels in the fingers and toes so consequently, there is less blood flow. This blood deficit can be the reason for the blue hue on your fingernails, particularly in cold or stressful conditions.
3. Medication Side Effects
Some medications can manifest a tint of blue in fingernails as a side effect. For instance, drugs used to treat malaria or certain psychiatric conditions can be the cause of discoloration. If you’ve just started taking a new medication and your nail color changes, you should talk to your doctor about it.
4. Heavy Metal Poisoning
Blue or bluish-gray discoloration of the fingernails occurs when certain toxic metals such as silver or copper are contributed to the body. Usually, this is the consequence of long-duration exposures in the industrial environment or via drinking contaminated water.
5. Methemoglobinemia
Methemoglobinemia, also known as “blue blood” is a very uncommon blood disorder in which the methemoglobin, the form of hemoglobin, present in the blood is produced in an abnormal amount. This can make the blood less able to deliver oxygen to the tissues, which can make the fingers and toes look blue.

When observing blue nails or toenails, it is essential to see a doctor to find out the reason. In Canada, the healthcare system offers a variety of diagnostic tools and treatments for such symptoms. The following diagnostic steps are common:
- Blood tests: These are done to check the oxygen levels and to rule out diseases like anemia or methemoglobinemia.
