Blue fingernails can result from low oxygen levels in red blood cells. The name of this illness is cyanosis. The skin and membrane below it turn a purplish blue tint as a result of insufficient oxygen in the blood.
Skin darkening could result from a high quantity of aberrant haemoglobin. The protein that carries oxygen through your blood is known as haemoglobin and goes by this name.
Cold temperatures can cause your fingernails to become blue. because blood vessels constrict in frigid conditions. It is challenging to deliver enough oxygen-rich blood to your nails because of the restricted pathways.
Nail colour will return to normal after warming up or rubbing your hands. This is probably a result of the chilly temperatures making your body’s blood supply insufficient.
Blue fingers are the body’s typical reaction to cold weather.
If your fingernails are still blue, it may indicate a structural issue or underlying disease that prevents the body from supplying oxygenated red blood.
BLUE FINGERS Blue fingernails can be a symptom of issues with the heart, blood vessels, lungs, or blood cells. Following conditions may lead to cyanosis:
Lung Conditions
COPD ( Emphysema, Chronic Bronchitis).
Asthma
syndrome of severe respiratory distress
pneumonia
respiratory embolism (blood in the lungs)
HEART ILLNESS
congenital heart condition (abnormal heart structure and vessels at birth).
the syndrome of Eisenmenger (late complication congenital heart disease).
enlarged heart failure
BLOOD CELLS THAT ARE USUAL
Methemoglobinemia comes in two forms.
Congenital conditions are those that you are born with; acquired conditions are those that develop as a result of ingesting specific foods, medications, or substances.
poisoning by carbon monoxide
Vera polycythemia (production too many red blood cell)
EXTRAORDINARY BLOOD VESSELS
Raynaud’s syndrome (blood vessels of the feet and hands constrict in an inappropriate manner)
CYANOSIS TREATMENT AND DIAGNOSIS
Using a noninvasive pulseoximeter is the simplest way to check your blood’s oxygenation level. Arterial blood gases (ABGs) are taken in order to determine the level of oxygen in your blood. This enables you to identify any potential causes of blue fingernails.
Finding the underlying cause is the first step in treating a blood disease.
