My legs are blue! It sounds like a silly thing to say but unless you’re a Smurf or a creature from the movie Avatar then having blue legs could be an indication of something very serious. When are blue legs a sign of a serious medical condition? Are there any natural remedies for blue legs or blue skin? What causes blue legs?
The medical term for blue legs is cyanosis. It is usually caused by a lack of oxygen in the blood. Cells within the blood carry around oxygen but these cells can become restricted or the body might be prevented from taking in enough oxygen.
Most of the causes of blue legs are quite serious and requoire medical attentoion. But some causes of blue legs are not serious and can be fixed using home remedies. especially if your legs have turned blue. Below we have the top 10 reasons why your legs might be blue and the cures which are often to treat the underlying cause.
1. You're Too Cold. This is the least serious and most curable reason that your legs are blue. The U.S Library of Medicine supports the fact the number one reason for cyanosis is because you’re cold. Depending on the color of your skin the less or more noticeable the blue will be.
If your legs turn blue when you are cold, another possible cause is Raynaud's disease. Raynaud's disease is a medical condition often associated with smokers when the extremities turn first white and then blue when exposed to low temperatures (CDC)
Cures: The reason is due to circulation. When you are cold the blood flows to your vital organs to keep them warm forgetting about your extremities. If you notice yourself turning blue from cold try to slowly warm yourself up. Put a light blanket over your legs or a second pair of socks.
2. Poisoning. According to the Centers for Disease Control, over 32, 000 deaths are caused by unintentional poisoning ever year. And one of the most common signs of poisoning are blue legs. The University of Maryland Medical Center reports that many poisoning cases are due to drug overdoses but some poisons are found in contaminated food, water or using chemicals in a confined space. In particular cyanide poisoning will cause cyanosis. Cyanide effects the body’s interaction with oxygen causing the blueness.
Cure: Always use cleaning products and other chemicals in a well ventilated area. If you notice a change in color made sure you get some air. You may require pure oxygen from a professional if you are displaying any other symptoms.
If you think you have been exposed to contaminated food -- especially if you think you have been exposed to cyanide -- you need to go to the hospital immediately. They will treat you with the antidote and usually oxygen therapy also.
3. Congenital Heart Diseases. Some children are born entirely blue. In fact the common name for this condition is "blue baby syndrome". Blue babies or blue legs can be caused by a condition known as cyanotic heart disease. Other heart conditions are linked to cyanosis in adults. According to the Texas heart Institute, some congenital heart defects indicate that the right side of the heart flows directly into the left side without traveling to the lungs to get more oxygen. As a result, the skin turns blue.
A related condition which can also cause blue legs is arteriosclerosis--hardening of the arteries or clogged arteries. As a study from Munich in 2008 reported, hardening of the arteries leads to less oxygen travelling in the blood, resulting in blue legs.
Cures: As mentioned by the Centers for Disease Control, congenital heart defects are present at birth and require professional medical attention.
Arteriosclerosis can be treated with diet and exercise but the particular type needs to be diagnosed by a doctor.
4. Asthma. Asthma can cause blue legs. Asthma restricts the flow of oxygen to the lungs and lack of oxygen is the root cause of the bluish tint in the skin in many cases. The exact cause is actually the wheezing. Wheezing during an attack creates an excessive expulsion of air. According to the U.S. Library of Medicine, the resulting decrease levels of oxygen in your blood turns your legs blue. (U.S Library of Medicine)
Cure: If you have been diagnosed with asthma and you’ve had a recent attack then follow your doctor’s advice and take your prescribed medication and the color should return to normal.
If you have been wheezing and are unsure why, try breathing with the aid of a paper bag and contact your doctor immediately as it may be a symptom of one of the respiratory conditions we discuss below.
5. Emphysema. According the National Heart Blood and Lung Institute, emphysema is the 4th leading cause of death in the United States and is strongly linked to smoking. As with asthma, the lack of oxygen is what causes your skin to turn blue.
If wheezing and coughing mucus or blood is occurring at the same time as the bluish tint then it could be emphysema.
Cures: Again treating the underlying condition is the way to treat the cyanosis. Usually sufferers are treated with oxygen therapy and drugs.
6. Deep vein thrombosis and Blood Clots. The Centers for Disease Control defines deep vein thrombosis as when a blood clot forms in the veins and it can eventually travel to the heart and cause a fatal pulmonary embolism.
Buergers disease can also cause blue legs. Buerger's disease is caused by the clotting of the veins in the hands and feet. It is normally associated with smoking. Buerger's disease is mostly a condition suffered by men.
Cure: If your blue leg or blue legs is combined with pain in that leg it is important to dial 911 right away as a blood clot can kill you with a matter of hours. Again, if your leg is blue and you feel pain, this is a medical emergency.
7. Circulatory Shock. This does not refer to the psychological condition of shock but the circulatory kind which can be caused by loss of blood or severe burns. It is when the blood does not pump around the body the way it is supposed to due to an underlying factor.
Cure: The way to treat this is by immediate medical attention as circulatory shock can be fatal within a short amount of time. However some tips to help before you receive attention are to elevate your legs, and stay warm.
8. Diabetes. Diabetes is a common cause of blue legs, especially as the incidence of diabetes skyrockets around the world. According to the Centers for Disease Control, people who have type 2 diabetes in particular are more likely to suffer from blue skin or blue legs because their cardiovascular function is often weaker. Diabetes can cause the narrowing of blood vessels when there is a high blood sugar level. Therefore, poor circulation could be causing your blue legs.
Cure: If you are experiencing blue legs and you have been diagnosed with diabetes, then you need to see your doctor as it could be a sign your condition is worsening. Also check that your blood sugar hasn’t spiked for some reason.
9. Stress. Stress can cause blue legs. A University of Michigan School of Medicine study in 1995 linked stress and blue legs. This is due to the effect of stress on the circulatory system. The chemicals released when you are stressed such as adrenalin put your body in "fight or flight" mode, changing the way your heart pumps blood around the body and sometimes the make up of the blood to prepare for physical injury.
10. Dehydration. The National Institute of Health lists dehydration as a cause of blue skin and blue legs. It is only at the very late stages however, that the legs cramp and give a blue appearance to the skin. Drinking 8 glasses of water a day at a minium can remedy most cases of dehydration but not this type of severe dehydration. Avoiding excessive intakes of caffeine also helps to slow dehydration during the day. This type of severe dehydration is also likely to cause other symptoms (Click here to read more on The Importance of Drinking Water).
Cures: The American Academy of Family Physicians recommends that anyone who is this severely dehydrated needs to be admitted to a hospital to receive intra venous fluids. Thereafter, you have to follow a daily regimen of drinking adequte amounts of water.
In summary, if you are not cold and have blue legs it is best to air on the side of caution and consult a doctor. Many of the causes of blue legs can be very dangerous.
