Feet Turn Purple When Sitting In A Chair: Top Full Information 2022

In this article, Focal Upright will provide information on the cause of feet turn purple when sitting in a chair, and how to treat it. Purple feet are usually caused by poor circulation. Sitting still for too long causes blood to pool, which leads to the feet turning purple. When this occurs, stand up and walk around or elevate your feet with something like a box. The article also offers additional information.

There are many conditions that can affect the flow of blood between your feet and heart. Treatment can improve circulation in many cases and bring your feet back to their natural, healthy colors.

Here are some health issues that could affect your circulation and color.

Ischemic Foot

Ischemia is a decrease in the healthy blood flow to one or more of your arteries. Ischemia means that your foot doesn’t get enough oxygen-rich blood.

A buildup of cholesterol plaque within one of your main blood arteries can cause Ischemic Foot. A blood clot could also block blood flow to an artery. An artery may be damaged by blunt trauma or a puncture wound. The following are risk factors for ischemic feet:

  • High cholesterol
  • High blood pressure
  • Diabetes
  • A history of peripheral vascular disease
  • Obesity

You may also notice toes or feet turning purple when walking. Ischemic foot is said to be extremely painful by the patients who have to go through it.


Healthy blood flow to your feet’s arteries is also reduced by acrocyanosis. Acrocyanosis refers to bluish discoloration in the skin caused by decreased oxygenation at the extremity.

This is usually caused by tiny blood vessels that are located near your skin’s surface. An artery can constrict suddenly when it spasms. This short tightening can dramatically reduce or stop blood flow to your artery.

Your hands can become blue or purple from Acrocyanosis. This is an uncommon condition with no noticeable symptoms. It is more common in women than it is in men.

Acrocyanosis can be caused by emotional stress or cold weather. Future episodes can be prevented by avoiding exposure to extremely cold temperatures, especially on the feet and hands.

Raynaud’s Disease

Raynaud’s Disease is in some ways similar to acrocyanosis. Both conditions can be triggered by cold and cause the skin to turn bluish-purple. Raynaud’s episodes can be brief and last only a few seconds. Episodes of Acrocyanosis tend to last. Raynaud’s affects your fingers and toes with smaller blood vessels, while Acrocyanosis affects your feet and hands with larger arteries.

Raynaud’s can be divided into two types: primary or secondary. Primary Raynaud’s is not linked to any underlying condition. It may be mild enough that you don’t realize it. Secondary Raynaud’s can be a sign of more severe conditions, such as:

  • Scleroderma
  • Other connective tissue diseases
  • Carpal tunnel syndrome
  • Arthritis

Raynaud’s is more common in women than it is in men. Raynaud’s can happen to anyone, but it is more common in the teens and 20s.


Two important things can happen to your feet when you have diabetes: a decrease in healthy nerve function and decreased circulation. You may notice discoloration in your feet and toes if your circulation is impaired by diabetes. Your feet may turn blue, purple, or gray. A rash or patches of purple or red skin may develop.

High blood sugar levels can cause circulation problems. This can lead to decreased circulation, particularly in the lower legs and feet. It is possible to notice swelling in the lower legs or ankles, as well as bruises and cuts that won’t heal.

Diabetes complications can be prevented by maintaining a healthy level of blood sugar. This means that you should aim for a fasting blood sugar level of less than 100 mg per deciliter.


Your circulation can be affected by cold temperatures. This is because your body prefers healthy circulation to your inner organs to normal blood flow to your extremities. You can restore normal circulation to your fingers and toes by moving from cold to warm indoors, or wearing gloves or socks.

Extreme cold weather can make the stakes even higher. Frostbite is a condition where your skin is exposed too cold. Your feet, hands, and ears are the most vulnerable. The skin becomes reddened and hard from superficial frostbite. Deep frostbite can make skin purple. It is possible for the skin to remain purple even after it has warmed up. This is a medical emergency.

Avoiding extreme cold temperatures is the best way to prevent frostbite. Make sure to protect all areas of your body from cold exposure by wearing clothing.


Lupus is perhaps the most debilitating of all these. Lupus is an autoimmune disease where your immune system attacks healthy tissues and organs.

Unfortunately, the cause of this bizarre disease is unknown. Researchers believe Lupus is caused by environmental and hereditary factors, although the nature of these conditions remains a mystery.

This less well-known disease can cause swelling, pain in different parts of the body, severe fatigue, headaches, rashes on your face, hair loss, and frequent fevers.

Low Blood Pressure Causes Purple Feet

Blood must flow to the feet. The heart must work correctly and blood pressure must be sufficient. The feet might not get enough blood in cases of heart disease or low blood pressure. Sometimes medications that are intended to raise blood pressure can constrict artery flow. This can cause poor circulation to your feet. These can cause purple discoloration to the feet.

Purple Feet Due To Vein Disease

The term “Vein disease” can be used in a wide variety of ways. There are many ways vein disease can cause color changes in your feet. These are just two examples.

“Blood clots” are also known as Deep Vein Thrombosis (DVT). DVT can block blood vessels from returning to the body if it is severe. The feet can become a pool of blood. The oxygen in the blood that pools becomes blue when it is no longer available. The feet may appear purple due to this. The clot can cause a blockage of artery flow by raising the pressure in the legs. This is known as phlegmasia. This can make the entire leg appear purple color.

“Leaky” valves: Veins are supposed to take blood from the feet and deliver it to the body. This is against gravity. This system relies on veins having valves. If the valves malfunction, some of the blood pools in the feet. This is also known as venous insufficiency. Pooled blood can lose its oxygen and appear blue, just like before. Patients with leaky valves are more likely to have dilated, bluish veins. These are known as reticular veins. These veins can create a blue effect on the feet when they are in clusters.

Peripheral Artery Disease (PAD)

People with diabetes or high blood pressure, or both, are more likely to develop peripheral artery disease. This condition is caused by the narrowing or clogging of the arteries by cholesterol.

When someone is suffering from this condition, the blood flow to the feet can be reduced by clogged arteries. This causes the feet and ankles to turn purple or discolor.

PAD is usually not diagnosed in the early stages. The symptoms are more obvious in the later stages.

Some of the most common symptoms are:

  • There is a lot of cramming in the feet, both while the patient is still and when they are moving.
  • Moderate to severe swelling
  • Numbness and weakness in the feet can often make it difficult to walk.
  • Foot discoloration that is purple or bluish
  • Unusual appearance and feel of toenails
  • Wounds and cuts heal more slowly than normal.

This disease affects many people because of several factors. To name just a few, obesity, diabetes, high cholesterol, unhealthy eating habits, and hereditary causes.

Depending on the position of the foot and the cause of the ischemia, red, white, and blue or purple skin discoloration is also typical of arterial disease affecting the feet. White discoloration of the skin, or pallor, occurs when arterial blood flow to the foot is critically low or completely blocked.

The foot skin can turn bluish if the blood flow is not improved quickly. This happens because the oxygen level drops in the foot tissue. If the blood flow improves, either by opening the blocked arteries or placing the foot below the heart, the affected skin will turn purplish-red. This is because blood returns to the foot and all blood vessels are maximally dilated to replenish the tissues with oxygen.

Preventing And Treating Purple Feet

Preventing And Treating Purple Feet

These conditions are usually treated with medications or procedures that maintain healthy circulation. Sometimes, a healthy lifestyle combined with preventive measures can be enough.

Amputation may be required if the foot’s circulation has been damaged to such an extent that it is threatening your foot tissue’s death, Doctors should only consider this option if other options have failed.

These treatments are possible before you take such drastic action:

Treating Ischemic Foot

You may also need to control your blood pressure, blood sugar, and quit smoking. Surgery may be necessary to attach a blood vessel to the affected artery from another part of the body in severe cases. This will allow blood to flow freely through the narrowed area of the artery.

Treating Acrocyanosis

Calcium channel blockers may be prescribed by your doctor. These medications keep your arteries open and help maintain healthy blood flow. They also reduce blood pressure. You can also relieve your symptoms by applying minoxidil and nicotinic acids derivatives topically.

Raynaud’s Disease Treatment

undefined Other medications such as vasodilators or calcium channel blockers may be required to reduce episodes. More invasive procedures are rarely necessary. Nerve surgery, which removes small nerves from the blood vessels around your feet and hands in severe cases, may be necessary to reduce the reaction to cold temperatures.

Treating Diabetes

To help maintain your blood sugar levels within a healthy range, your doctor may recommend medications such as metformin. You may need to have regular insulin injections if you have type 2 diabetes.

Frostbite Treatment

You can treat frostbite or other cold-weather injuries by warming, soaking the affected skin, and then letting it dry in a warm tub for about half an hour. Do not rub frostbitten skin. It should be treated with care and evaluated by a doctor. Surgery may be necessary if any tissue is damaged permanently. This could also apply to your toes.

Lupus Treatment

This very dangerous disease is not curable. There are many treatment options available to manage the symptoms and provide relief. A treatment that is initiated early is more effective than one that is delayed.

The most commonly used form of treatment is medication. Your specific symptoms will determine which medicines you’ll be prescribed. NSAIDs are the most common treatment.

It is important to be extra cautious about triggers. People who are sensitive should avoid sunlight as much as possible. People who are prone to getting cold should be cautious and avoid getting one.

PAD Treatment

If the patient wishes to improve, they will need to make significant lifestyle changes and commit to their recovery. The treatment is usually done with two goals in mind: symptom management and reducing stroke risk.

Depending on your medical condition, your doctor may recommend any of these. Many doctors will prescribe medications to lower blood pressure, cholesterol, and blood sugar.

Warnings And Precautions

If you notice your feet becoming cold or purple, see your doctor immediately. PAD of your lower extremities, like atherosclerosis, is treatable. If you notice any symptoms of diabetes or PAD, you should seek immediate medical attention.

If one of your feet becomes pale, blue, or cold suddenly, get immediate medical attention. This can happen even if you’re standing or sitting.
