Causes of Poor Circulation

Do your legs ache and feel heavy at the end of the day? Do you have difficulty sitting or standing still for long periods of time? Can you see prominent spider veins and varicose veins on the surface of your skin? These are all signs or poor circulation and it indicates that you may be suffering from poor circulation in legs. Bad circulation can occur for a number of reasons, but the most prominent and dangerous cause of poor circulation in legs is a vein disease called chronic venous insufficiency. In this article, we discuss the signs and symptoms of poor circulation, what causes poor circulation in legs, and how to improve circulation in legs at one of the best vein treatment clinic in Houston TX.

Signs of Poor Circulation

Before we discuss the causes of poor circulation and how to treat bad circulation in legs, we need to discuss the signs and symptoms of poor circulation so you can identify it. Signs of poor circulation often get attributed to signs of aging, which makes the underlying disease hard to diagnose. As such, if you notice any of the following symptoms of poor circulation, please consult a vein clinic immediately.

  • Heaviness and aching in legs, especially at the end of the day.
  • Swollen ankles and feet, which is usually an indication of blood accumulation in your legs because of poor circulation.
  • Patchy discoloration of skin and infections, which is often caused by reduced blood flow.
  • Development of leg ulcers (non-healing wounds) because of reduced blood flow in the legs.
  • Formation of spider veins or varicose veins, i.e., veins that bulge out of the skin. This occurs because poor circulation can lead to blood accumulation in the veins, which can cause them to dilate.

What Causes Poor Circulation in Legs?

Poor circulation in legs can occur for a number of reasons such as blood clots, diabetes, Raynaud’s disease, peripheral artery disease, or chronic venous insufficiency. Let’s look at all of these potential causes of poor circulation in legs individually.

Chronic Venous Insufficiency (CVI)

Chronic Venous Insufficiency is one of the top cause of poor circulation in legs. This is a vein disease in which the valves in the veins malfunction and fail to encourage healthy blood flow to the heart. As a result of that, blood flows back down due to gravity and pools around the legs. As the accumulated blood applies pressure on the vein walls, they dilate and lead to spider veins and varicose veins. This vein disease generally causes poor circulation in legs, which is why it leads to symptoms like heavy legs, swollen feet, etc.

Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis is associated with the aforementioned vein disease. This is a condition in which the accumulated blood may clot inside the veins. This creates a blockage, which leads to reduced blood flow. If the blood clots break, they may also travel to the lungs and lead to a potentially fatal condition called pulmonary embolism.

Peripheral Artery Disease (PAD)

Peripheral Artery Disease (PAD) is a condition in which your arteries and blood vessels constrict and narrow down. In some cases, the blood vessels also develop plaque and stiffen. In either case, there’s a reduced blood flow, which causes poor circulation issues. If left untreated, poor circulation caused by PAD can also lead to a stroke or heart attack.


If you suffer from diabetes, you don’t just have to worry about your blood sugar. Advanced stages of diabetes can also lead to poor circulation. Furthermore, diabetes can also reduce sensation in your extremities, which makes poor circulation hard to even identify or notice. If left untreated, it can also lead to high blood pressure or heart disease.

Raynaud’s Disease

Raynaud’s Disease is associated with the aforementioned PAD. It’s a disease in which the blood vessels and arteries in your hands and toes constrict, leading to reduced blood flow. You can identify this disease if you suffer from chronic cold hands and feet.

How to Improve Circulation in Legs? (Temporary Solutions)

The following are some methods and tips to improve circulation in legs. These aren’t permanent solutions, but they can momentarily make you feel better:

  • Compression Stockings: These are stockings you can wear to apply pressure on your blood vessels in order to push blood along and improve circulation in legs. This will only work if you suffer from poor circulation in legs because of vein disease.
  • Cardio: If you have poor circulation in legs, you can engage in cardio exercises that target the calves such as running, swimming, and cycling. This will encourage blood flow to the heart.
  • Elevating Legs: This method will also be useful only if poor circulation in legs is caused by venous insufficiency. In this case, if you elevate your legs over the level of your heart, the accumulated blood may travel in the correct direction and provide relief.

How to Improve Circulation in Legs? (Permanent Solutions)

The only way to permanently improve circulation in legs is to treat the underlying disease, whether it’s chronic venous insufficiency, deep vein thrombosis, peripheral artery disease, or any other. That’s why it’s crucial to visit one of the best vein treatment clinic in your area to seek diagnosis and effective treatment. If your poor circulation is caused by vein disease, the most effective treatments available are radiofrequency ablation, endovenous laser treatment, and venaseal. All of these treatments are minimally-invasive, non-surgical, they cause minimal pain and discomfort, and improve circulation in legs immediately.
