Blue Skin Symptoms

Blue skin is an unwelcome development, to say the least, whether it's all over the body or restricted to the hands, face, or a particular skin bump. It can arise early or late in life and may come and go or be present all the time, depending on the cause. In many cases, removing the factor that caused the discoloration or undergoing medical treatment will allow the skin to return to its normal color.

Symptoms that can be associated with blue skin include:

Blue Skin Causes Overview

Insufficient blood flow

If not enough blood is being delivered to the extremities, the resulting lack of oxygen can cause the skin to turn blue.

  • Blood vessel constriction : Intermittent constriction of small blood vessels in the extremities can cause blue skin. This may be triggered in the hands by exposure to the cold, in which case the skin will turn first white, then blue, then red (Raynaud's disease).
  • Arterial blockage : A clot blocking an artery can stop blood from flowing to an extremity, such as one of the feet.

Insufficient oxygen

In some conditions, blue skin occurs because the blood is carrying an abnormally low amount of oxygen.

  • Heart conditions : Structural abnormalities in the heart can cause blood with low oxygen content to be pumped to the rest of the body instead of entering the lungs to pick up oxygen. Inherited conditions are commonly diagnosed in infancy or early childhood.
  • Respiratory conditions : If the lungs are not functioning correctly, the body will not be able to get all of the oxygen it needs. This could be caused by an acute problem or an exacerbation of a chronic condition such as COPD.
  • High altitude : The lower oxygen content in the air at high altitudes can cause a condition characterized by bluish skin, coughing, and difficulty breathing.
  • Abnormal hemoglobin : Hemoglobin is the molecule that carries most of the oxygen in the blood. It can take on an abnormal and less functional form, resulting in decreased oxygen delivery to the body.

Medications or supplements

  • Amiodarone : This medication is used for certain heart conditions and can cause blue skin in areas that are exposed to the sun.
  • Silver colloid : Taking silver colloid for a long period of time can cause silver to deposit in the skin, resulting in a blue color, particularly in areas that are exposed to the sun.

Skin conditions

  • Birthmarks : Some types of skin marks that are present early in life have a blue color.
  • Moles : Some moles have a bluish appearance.

Injury

A fall or bump can result in a bruise, where small blood vessels are damaged and leak blood (ecchymosis). The blood initially appears as a bluish color under the skin.

  6. 6.Interstitial Lung Disease

    Interstitial lung disease is a group of lung disorders in which the deep lung tissues become inflamed and build up scar tissue (similar to a scab which develops on skin after a cut). Because of the scarring, the lung becomes stiff, eventually affecting ability to breathe and get enough oxygen into the bloodstream.

    This condition usually lasts a few years, and may affect your life expectancy (consultation with a physician is required).

    Rarity:
    Rare
    Top Symptoms:
    dry cough, shortness of breath, fingers looking plump
    Symptoms that always occur with interstitial lung disease:
    dry cough
    Urgency:
    Primary care doctor
  7. 7.Foreign Body Aspiration

    Foreign body aspiration can be a life-threatening emergency. An aspirated solid or semisolid object may lodge in the larynx or trachea. If the object is large enough to cause nearly complete obstruction of the airway, asphyxia may rapidly cause death.

    Resolves as soon as treatment is provided

    Rarity:
    Rare
    Top Symptoms:
    cough, fever, shortness of breath, cough with dry or watery sputum, wheezing
    Symptoms that always occur with foreign body aspiration:
    swallowing of something potentially harmful
    Urgency:
    Emergency medical service
  8. 8.Bronchiectasis

    Bronchiectasis is destruction and widening of the large airways. Mucus builds up in these airways and can get infected, causing a pneumonia.

    Rarity:
    Rare
    Top Symptoms:
    cough, shortness of breath, wheezing, runny nose, mucous dripping in the back of the throat
    Urgency:
    Primary care doctor
  9. 9.Myocarditis

    The myocardium is the muscular tissue that makes up the walls of the heart, allowing it to contract and push blood throughout the body. Myocarditis is the condition when this muscular tissue becomes inflamed, often as a result of an infection, causing the heart to struggle to pump blood.

    If myocarditis has not damaged the heart too much, expect a 2-3 week course of medication to treat infection.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, headache, shortness of breath, muscle aches, chest pain
    Urgency:
    Hospital emergency room
  10. 10.Eisenmenger Syndrome (Tardive Cyanosis)

    Eisenmenger syndrome is a complication due to a heart defect. The defect causes increased blood flow to the lungs instead of the body.

    This condition is considered irreversible, but heart transplantation is an option for some patients.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, shortness of breath on exertion, shortness of breath when lying down, decreased exercise tolerance

Blue Skin Treatments and Relief

Many causes of blue skin can be addressed at a regular appointment rather than in the emergency room. However, you may need urgent treatment, such as supplemental oxygen, if there is insufficient oxygen in your blood. In addition, if your blue skin is caused by interrupted blood flow to an extremity, immediate treatment is necessary to avoid permanent damage or even loss of the limb.

Seek emergency treatment if:

  • You have sudden onset of blue discoloration of an extremity, particularly if the extremity is also painful or tingly.
  • Your lips or tongue have turned blue.
  • You are experiencing chest pain.
  • You are having difficulty breathing.
  • You have headache, confusion, or dizziness.

In some cases, even though emergency treatment isn't necessary, you may need medical evaluation and treatment.

Make an appointment with your medical provider if:

  • You are bruising more easily than usual or without any known injury.
  • You have started any new medications recently.
  • Your hands are becoming discolored whenever they get cold.
  • You have a previously diagnosed heart or respiratory condition.
  • You have a blue mole that has changed in color, shape, or size.

Your medical provider may prescribe one of the following treatments, depending on the cause of the blue skin symptoms:

  • Stopping a medication that could be causing the blue skin.
  • Starting a medication to improve blood flow to the hands.
  • Adding or adjusting treatment for an underlying chronic medical condition.
  • Referral to a specialist as needed for a heart or respiratory condition.
  • Removal of a mole.

Some home treatments may help with blue skin.

  • Avoid the cold if you find that it is causing your hands to turn blue.
  • Descend to a lower location if you recently arrived somewhere with a high altitude.
  • Cut down on smoking or quit altogether.
  • For a bruise, ice and compression can help prevent swelling.

FAQs About Blue Skin

Here are some frequently asked questions about blue skin.

Can you turn blue from colloidal silver?

Some people use colloidal silver as a supplement, but it has no effective medical use and may be harmful. Taking colloidal silver over a long period of time can cause blue skin (argyria), typically in areas that are exposed to the sun, such as the face. This occurs because silver builds up within the skin. Unfortunately, the blue color is usually permanent, even after you stop taking the colloidal silver.

Is blue skin hereditary?

Blue skin can be inherited in a condition called methemoglobinemia. In hereditary methemoglobinemia, there is a genetic mutation in some of the body’s hemoglobin, the molecule that carries most of the blood’s oxygen. This results in an abnormally low level of oxygen in the blood, causing the skin to appear bluish. People with this condition may experience symptoms when exercising, such as headaches and shortness of breath, due to the lower oxygen level in the blood.

Can you prevent developing blue skin?

Some causes of blue skin are preventable. Avoid colloidal silver, which has no medical purpose. Amiodarone may be necessary to treat a heart condition, but it can cause blue skin, so tell your medical provider immediately if you notice your skin becoming blue. If you have been diagnosed with a medical condition that can cause intermittent blue skin, you may be able to avoid particular situations that will cause your skin to change color.

Why is my bruise blue?

Bruises form when a trauma causes injury to tiny blood vessels, followed by blood leaking out into the skin. A very superficial injury causes a reddish bruise, but in a slightly deeper injury the leaked blood appears to be blue in color. As the injury heals and blood is broken down into its components, the color of the bruise changes to yellow or green.

Why are my hands blue?

Your hands can turn blue due to a low level of oxygen in the body, caused by a problem with the lungs or heart. Seek emergency treatment if you are having difficulty breathing, or if your tongue and lips are also blue. If your hands turned blue after exposure to the cold, you may have a condition called Raynaud’s phenomenon. In this case the hands turn white, then blue, then red. Raynaud’s phenomenon can be a sign of an underlying medical condition, so it is important to see a medical provider.
