Leg Swelling: What It Is, Causes, Risks & Venous Diseases 


When you experience leg swelling it can be alarming. Not only is it a noticeable condition, but you also might experience anxiety over the fact that there might be something wrong. So, you might find yourself searching “leg swelling clinic near me” or “leg swelling doctor near me.” Consider our clinic’s assessment of leg swelling and the type of treatment options.

Don’t fret. If your leg is swelling, we’re here to give you the information that you need to figure out what is going on. Let’s discuss leg swelling so that you can be more informed about the condition.


Leg Swelling Causes


Multiple different things can cause leg swelling. For one, it might be because of fluid buildup factors, that is, peripheral edema. Peripheral edema is going to occur when your blood vessels produce fluid that sneaks into your tissue. When there is extra fluid that has built up in your legs, your leg tissue is going to swell. This explains why your legs appear swollen—it is simply built-up fluid. Edema is not clinically present until fluid has increased by 2.5 litres.

A second thing to consider is leg swelling venous disorders. Vein diseases are complex, but to put things simply, your heart functions to pump blood through your body. However, sometimes, when the valves in your heart aren’t working properly, there a buildup of blood will occur in your leg veins.

Leg Swelling Visual Examples

Venous Edema: Venous edema is a noticeable increase in the volume of fluid in the skin and subcutaneous tissue. When putting pressure on the area, the indentation remains on the skin after the pressure is released.

Lympathic Edema, Lipedema: Lymphedema is swelling of lymph fluid in the body because of build up. Think of lymph nodes acting like a drain in your sink. If the drain is clogged, the fluid is unable to drain.

Common Causes of Edema

This can appear alarming because your legs will inevitably swell substantially. You’re more likely to be at risk for venous diseases if you’re overweight, pregnant, have a family history, or have experienced trauma in your leg because of past surgeries or blood clots.

Different Types of Body Parts That Can Swell


Although leg swelling is one phenomenon that could affect your body because of either venous diseases or built-up fluid, other parts of your body can swell, too. Be on the lookout for leg swelling of course, but also keep an eye out for any ankle swelling, foot swelling, limb swelling, and below knee swelling.


Leg Swelling Assessment


If you’re concerned and have leg swelling, you must get the issue checked out by a healthcare professional. Because conditions like Peripheral Arterial Disease, for example, can lead to issues like heart attacks or strokes, you want to be proactive if you think there’s an issue.


Edema Evaluation


  • History
  • Physical examination 
  • Lab tests/ECG
  • Imaging

Important Questions to Ask in Edema Evaluation


  • What is the duration?
  • Is the edema painful?
  • Is the patient on any medication?
  • Does edema improve overnight or worsen in evenings?
  • Any history of abdominal/pelvic neoplasm or radiation?
  • Is there history consistent with sleep apnoea?

Venous Diseases and Leg Swelling


Since there are several different kinds of venous diseases, it’s important to discuss the different kinds of vein-related issues that cause leg swelling. For example, you might have deep vein thrombosis, which is a condition where a blood clot forms inside of your veins. This could happen in one vein or several veins, and this often happens if you’re immobile for a long period.

Another condition that you might have if you’re experiencing leg swelling, is varicose veins. Varicose veins are relatively common, as they are simply twisted and enlarged veins. Because walking and standing puts excess pressure on your veins in the lower body, varicose veins are veins that are close to the skin’s surface, that eventually get prominent and visible.

Finally, you may have peripheral arterial disease. When you have this condition, your legs have a blockage that stops blood vessels from carrying blood to the legs, from the heart. The risk of this is much higher in seniors, especially seniors who smoke, have high cholesterol, and diabetes.

What are Varicose Veins?

Blood circulation to the legs involves two systems broadly. First is the arterial system taking blood to the legs from the heart carrying oxygenated blood. Second is the venous system taking deoxygenated blood from the legs to the heart. This venous system comprises two parts: superficial venous system under the skin and deep venous system next to the bones and the deep muscles.
