Leg swelling is a common symptom that can range from mild to severe and has many causes. Sometimes, the cause is temporary and of mild to moderate concern, but leg swelling may point to a more serious health condition in other cases. Learning more about leg swelling helps people know when to seek help from a vascular doctor or surgeon.
One of the most common causes of leg swelling is fluid buildup, also called edema. This can happen when the body holds onto extra fluid, especially in the lower legs and feet. Sitting or standing for long periods can worsen edema. People who eat salty foods, take certain medications, or have health conditions like kidney or heart problems may notice more swelling.
Vein problems are another reason for leg swelling. When veins do not work the right way, blood can collect in the legs and cause them to swell. This condition is called venous insufficiency. People with this issue may also notice heaviness, aching, or skin changes. Varicose veins and deep vein thrombosis (DVT) are two examples of vein problems that can lead to swelling and should be checked by a doctor.
Swelling can also happen after an injury or infection. A sprained ankle or a broken bone may cause the body to send more blood and fluid to the injured area. Infections like cellulitis can lead to redness, warmth, and swelling in one leg. These causes usually affect just one leg and may come with pain or fever.
The lymphatic system helps the body remove waste and fluid. If this system is blocked or damaged, it can lead to a condition known as lymphedema. This condition often causes long-term leg swelling and may include a heavy feeling or tight skin. Lymphedema can happen after cancer treatment, surgery, or due to other health conditions.
Some cases of leg swelling are linked to organ function. The heart, liver, and kidneys all help manage fluid in the body. When these organs are not working right, fluid can build up in the legs and other areas. People with these health problems may also notice shortness of breath, tiredness, or swelling in other parts of the body.
It is important to see a vascular doctor if leg swelling is sudden, painful, or does not go away, especially with rest and elevation of the leg. Swelling that only affects one leg, comes with redness, or causes trouble walking should also be checked. A doctor can run tests to find the cause and offer the right treatment.
Leg swelling can have many causes, from minor issues to serious health problems. Seeing a vascular doctor helps people get the answers they need and the care they deserve. With the right treatment, it is possible to reduce swelling and feel better.
