Leg Swelling: When Does It Indicate Something More Serious?

Leg Swelling: When Does It Indicate Something More Serious?

North Atlanta Vascular Clinic and Vein Center


An injury, inflamed joints or tissues, fluid buildup, or prolonged standing or sitting can cause leg or ankle swelling. A swollen leg can appear larger than normal, causing difficulty in walking, chest pain, dizziness, and more. Determining the cause of leg swelling can help prevent more serious diseases from developing.

Causes and Treatment of Leg Swelling


Cellulitis, a bacterial skin infection, can cause warm skin, redness, and swelling that spreads quickly. 

Antibiotics can treat this condition. However, visit your doctor if the swelling does not subside or worsens even after treatment. 

Chronic Venous Insufficiency (CVI)

CVI affects the leg vein valves that carry blood to the heart causing it to malfunction. Due to this, some of the blood will flow backward and collect in the ankles and lower legs, thus causing swelling. 

Treatment options for CVI are:

  • Keeping your legs elevated to improve blood flow
  • Wearing compression stockings to reduce swelling
  • Medications like aspirin
  • Undergoing radiofrequency ablation that uses heat to close the affected vein

Foot or Ankle Injury

An inflammation followed by an ankle or foot injury can cause swelling. 

An ankle sprain, a very common foot injury, can be treated at home by:

  • Elevating the foot above the waist
  • Wearing an ankle brace
  • Applying a compression wrap or ice in a thin cloth for 20 minutes 

Blood Clots

A blood clot, also referred to as deep vein thrombosis, in a leg vein can affect the blood flow to the heart, allowing blood to flow back and pool in the legs, thus causing swelling. A DVT might need urgent medical attention.

It can be treated by:

  • Elevating the affected leg
  • Taking blood thinners or anticoagulant medications 
  • Wearing compression stockings to promote blood flow
  • Undergoing a stent procedure, where a stent is inserted into the vein to keep it open


Swelling during pregnancy is caused by hormonal changes and pressure on veins due to the extra weight of your uterus.

Swollen legs during pregnancy might also indicate preeclampsia. It’s a life-threatening condition where the blood pressure and protein levels in the urine are dangerously high and requires immediate medical attention. This condition can occur during the 2nd or 3rd trimester of pregnancy or 6 weeks after giving birth. 

Here are tips to ease leg swelling during pregnancy:

  • Eat potassium-rich foods, reduce salt intake, and avoid caffeine 
  • Wear comfortable shoes and support stockings
  • Elevate the feet when resting
  • Avoid prolonged standing
  • Apply a cold compress
  • Wear shoes that feel comfortable and not too tight
  • Avoid spending too much time outdoors in the hot weather

Liver Disease

Low albumin levels (a protein produced by a healthy liver to prevent fluid leak) caused as a result of liver disease can cause fluid buildup in the legs resulting in swelling.

Treatments include: 

  • Exercising regularly 
  • Avoiding alcohol
  • Eating a healthy diet
  • Limiting salt intake

Chronic Kidney Disease

During end-stage renal disease, kidneys cannot remove waste and extra fluid from the body, causing fluid buildup that leads to swelling.

Here are tips to help prevent kidney disease:

  • Quit smoking
  • Limit alcohol
  • Reduce salt and fat in your diet
  • Maintain healthy blood sugar levels
  • Maintain a healthy weight
  • Exercise 30 minutes a day
  • Maintain a healthy blood pressure 

Other conditions which can cause leg swelling are:

  • Medications
  • Hypothyroidism
  • Lymphedema
