Why do my nail beds look purple?
Cyanosis is when skin, nailbeds, or lips turn a shade of blue, purple, or grayish. This is due to blood carrying less oxygen, which means bodily structures such as organs might not be receiving enough oxygen.
Why are my nail beds blue?

What is the most common cause of cyanosis?
Cyanosis, broadly speaking, is caused by disorders of deoxygenated hemoglobin and disorders of abnormal hemoglobin. Oxygen might not reach hemoglobin in an adequate or sufficient amount as a result of conditions affecting the respiratory system, cardiovascular system, and the central nervous system (CNS).

Common Causes of Central Cyanosis
- Impaired gas exchange secondary to pneumonia.
- Embolism and ventilation perfusion mismatch.
- Impaired gas diffusion via the alveoli.
- High altitude.
- Anatomic shunts.
- Right to left shunt in congenital heart disease.
- Arteriovenous malformation.
Why does lack of oxygen cause cyanosis?
Cyanosis is caused due to an absolute increase in the deoxygenated hemoglobin. Therefore, in anemic patients, greater desaturation of arterial hemoglobin is required for cyanosis to manifest, as compared to individuals with normal hemoglobin levels.
