What Causes Lack of Circulation In Your Legs

You know that feeling when you’ve been sitting in the same place for too long and your leg falls asleep? Or when you caught your leg in a weird position and the tingling feeling starts to set in?

We’ve all been there, and that feeling is not something one would describe as “comfortable.” Rather, it feels like pins and needles in your legs and is something we’d rather not experience. 

So why does this happen?

In short, your circulation has been cut off causing circulation problems in your legs. 

And when you have vein problems, this tingling and uncomfortable feeling happens more often than just sitting in the same place for too long. For those that suffer from venous insufficiency, you may find yourself dealing with this feeling more often than you’d like.

In order to help you tackle a lack of circulation in your legs, it’s best to find out why this problem happens in the first place.

Why Are You Suffering From Poor Leg Circulation?

Circulation issues occur when blood flow to a part of your body (commonly legs) is reduced. Your circulatory system is what keeps blood, oxygen, and vital nutrients flowing throughout your body. 

So, it’s safe to assume that when your circulation is off, it’s not something you should ignore because it means that your blood isn’t flowing where it should be.

The first question you may ask yourself is: Why is this happening?

See below for a number of factors that could be causing poor blood circulation in your legs.

Blood Clots

Clotting is one of the leading causes of circulation problems in the legs. Just like the name states, blood clots keep your blood from flowing as it needs to, to varying degrees. With a less severe clot, it blocks the flow partially, whereas, with a more severe clot, it blocks the blood flow entirely.

Healthy vein valves allow blood to flow in one direction only. When your circulation isn’t functioning properly, the blood flows backward, causing strain and damage, resulting in varicose veins.

Blood clots have the potential to be very dangerous. If you have a blood clot in your leg and it breaks away, it can travel up to your lungs or your heart, which has the potential to lead to death. However, if found early on, blood clots can be easily treated.

Varicose Veins

Vein issues are another reason you may find yourself suffering from circulation problems in the legs. If your veins are at all damaged, blood will not be able to flow through them with the ease it needs in order to keep your legs looking and functioning correctly. 

And this means circulation problems, possibly even blood clots if left untreated for too long. Varicose veins are found primarily in the legs, so pay attention to your circulation problems and what they could possibly mean. 


Carrying extra weight on your body can open the door to a great number of health issues, but one of the major ones is vein and circulation problems.

This is due to the fact that extra weight puts additional pressure on your veins and hinders their ability to do their job of circulating blood. 

The scary part about this is the fact that it is more difficult for those suffering from obesity to realize they have vein issues. Why is that? Because the extra fat hides the veins’ problematic appearance from being seen.

 Thus it is vital to keep your weight at a manageable level to lower your risk factor.


Diabetes is known for its effect on your blood sugar, but unfortunately the problems do not stop there. If left untreated, diabetes can lead to issues with poor circulation due to a lack of sensation in your arms and legs. 

And these are just a couple of problems you’ll experience with diabetes. It is best to make sure your all-around health is on track if you think you may be diabetic.

These are the leading causes of circulation issues in the legs, and are things that you want to be paying attention to in order to avoid not only bad circulation, but additional health problems as well.

Here are some of the main signs that you may have poor circulation:

  • Numbness
  • Cold hands and feet
  • Fatigue
  • Varicose veins
  • Muscle cramps
  • Swelling in your legs
  • Digestive issues
  • Ulcers in your legs and feet
  • Tingling feeling
  • Dizziness

It is best to tackle these issues as soon as possible before they grow into potentially life-threatening problems. If you think you are suffering from circulation issues, schedule an appointment with a Vein Clinics of America vein specialist today.
