Usually, poor circulation in leg means decreased blood flow. If you are having poor circulation in leg, you might need to find out what's the underlying disease.

Circulation in leg is very imporant for us to perform daily rountine activities. If you can not walk or stand for a period of time, then you should hurry to the doctor to be treated.

Here, I summerize some possible causes of poor circulation in leg, and I hope it can provide some help.

Possible causes:

1. Peripheral artery disease (PAD).

PAD can affect your arteries, which may cause your leg receiving less blood fow.

2. Atherosclerosis

This condition is serious. If left untreated, it may lead to heart attack, stroke, or heart failure.

3. Spinal cord injury

Poor circulation may lead to spinal cord injuries.

4. An unhealthy lifestyle

If you sit in one position for long periods of time, you may have poor circulation in leg too.

So, if you are not sure about the reason behind the symptoms, you'd better go to the doctor and get a diagnosis.

Circulation in the body is: heart - arteries in leg - microvessels - veins in leg - heart.

Poor circulation could be a result of:

  1. heart failure (insufficiency of heart pump) 
  2. peripheral artery disease (atherosclerosis, embolism etc.) 
  3. vein problem (varicose veins, venous insufficiency etc.)
  4. microvessel problem (diabetic microangiopathy etc.)
The following are some of the most recognized causes of poor circulation in leg:

Peripheral artery disease

Blood clots

Varicose veins
