Poor circulation in the feet can cause the feet to become cold, discolored, or numb. Sometimes, it is a symptom of an underlying condition.
The body transports blood, oxygen, and nutrients to cells around the body through the circulatory system. If blood vessels in an area close, harden, or narrow, a person may develop reduced circulation.
In this article, we will look at the symptoms of poor circulation in the feet, potential causes, treatments, and self-care techniques.
People with poor circulation may notice their feet feel cold or numb. They may also notice discoloration. The feet may turn red, blue, purple, or white.
These symptoms may worsen in certain situations, such as when a person sits still for long periods of time or goes outside in cold weather. However, for some people, these symptoms may be constant or flare up due to an underlying condition.
Additional symptoms of poor circulationÂ can include:
Below are some of the underlying conditions that may cause reduced circulation.
Raynaudâ€™s disease syndrome causes blood vessels to narrow when someone is cold or, sometimes, when stressed. This limits the amount of blood flowing to the fingers and toes.Â RarelyTrusted Source , it may affect the nose, ears, nipples, and lips.
The symptoms include:
These symptoms can last as little as 1 minute or as long as several hours.
Most people with Raynaudâ€™s disease have the primary form of the condition. Some people have secondary Raynaudâ€™s, which occurs as a result of another illness. Secondary Raynaudâ€™s tends to be more severe.
There is no cure for Raynaudâ€™s, but it is possible to reduce the symptoms and potentially reduce the frequency of attacks with the help of medical treatment and lifestyle changes.
Acrocyanosis is a condition that causes the extremities, such as the toes, to turn blue. This occurs when the blood vessels constrict, preventing blood flow and oxygen from moving through that part of the body.
It is a similar condition to Raynaudâ€™s phenomenon, but scientists understand itÂ much less than they do Raynaudâ€™s. The main symptoms include:
As with Raynaudâ€™s, there are two types of acrocyanosis: primary and secondary. Primary acrocyanosis occurs on its own and typically affects both sides of the body, for example, both feet. Scientists are not sure what causes it or how best to treat it.
If a person with diabetes does not receive any treatment, they could develop reduced circulation in the feet, as well as foot ulcers that do not heal.
Managing diabetes effectively can help prevent foot problems. People with diabetes should receive an annual foot examination to make sure that they have not developed poor circulation, ulcers, or neuropathy.
Some people who have arteriosclerosis do not exhibit any symptoms, while others may develop some. The symptoms vary depending on which arteries the condition has affected, and they may include:
Treatment for arteriosclerosis may include medication, such as medicine to control a personâ€™sÂ cholesterol, or possibly surgery to open blocked arteries or remove plaque buildup.
If left untreated, arteriosclerosis can turn intoÂ peripheral artery disease (PAD). PAD occurs when plaque builds up in arteries. ThisÂ can reduce or even stopTrusted Source blood flow, resulting in tissue death and potentially amputation.
Symptoms may include:
Prescription medication can improve symptoms in people with reduced circulation. In more severe cases, a person may require surgery.
Factors that can increase the likelihood of low circulation include:
Smoking can reduce blood flow by affecting a personâ€™s cardiovascular system. ItÂ raisesTrusted Source the risk of arteriosclerosis and PAD.
Caffeine,Â alcohol, andÂ stress can also constrict blood vessels, causing or worsening circulation problems. Certain sitting positions may also reduce blood flow, according to aÂ 2015 studyTrusted Source .
A doctor can diagnose circulation problems and any underlying issues that may be causing them. They may ask about a personâ€™s medical history, as well as their symptoms and when they occur.
Doctors may diagnose Raynaudâ€™s or acrocyanosis based on symptoms and aÂ physical examination. TheyÂ may alsoTrusted Source try cold stimulation to observe the bodyâ€™s response, or a nailfold capillaroscopy, which can detect diseases associated with secondary Raynaudâ€™s.
Doctors diagnose PAD via a physical examination and by comparing the blood pressure in a personâ€™s arm versus their ankle. They can diagnose diabetes using a blood sugar or urine test.
The best way to improve circulation in the feet is to treat any underlying conditions that may be causing it. If doctors cannot pinpoint a cause, however, a number of self-care strategies may help.
People can try:
Anyone experiencing persistent circulation problems in the feet should speak with a doctor. Sometimes, this is a symptom of an underlying condition that requires treatment.
A person should call 911 or contact the local emergency department if they experience:
These symptoms can indicateÂ deep vein thrombosis, which can be life threatening.
Poor circulation can occur for many reasons. Sometimes, it is due to a disease that requires treatment. However, it can also occur on its own, as a result of a condition such as primary Raynaudâ€™s.
Staying warm and active, wearing compression socks, and managing stress may help people relieve the symptoms of poor circulation in the feet. However, it is important to seek guidance from a doctor so that they can rule out underlying conditions.
