    Several conditions with different causes can lead to swollen legs or swelling in legs from the knee down. Most believe that swelling in the lower leg is a result of poor blood circulation.

    However, this is not always the cause. If you want a quick and efficient treatment for your swelling in legs, The Comfort Zone, it’s self-directed guidance expedite your recovery and get you back into your regular activities.

    There are two major causes when looking at what causes swollen legs from the knee down; fluid buildup and inflammation. Let’s have a look into each of them.

    Common Causes

    Peripheral edema, or leg swelling, is not always a sign of heart problems and improper blood circulation. This can be caused by other factors, such as:


    During pregnancy, the body usually produces 50% more fluid and blood in order to support the development of the baby. This additional amount of blood and fluids can lead to swollen legs (edema). The increase in fluids purportedly softens the body, thus allowing it to expand as the baby grows. These extra fluids amount up to 25% of the extra weight during pregnancy.

    It often begins noticeably in the fifth month and gets more obvious around the third trimester. Also, the weight of the baby can press on the blood vessels leading to the lower extremities, reducing circulation.


    Pain relievers or prescription medication for high blood pressure and diabetes can also lead to swollen legs. Additionally, antidepressants, such as phenelzine and amitriptyline, can also lead to edema. Hormone medication, including estrogen, birth control pills, and testosterone can all cause edema, as well.

    Sitting or Standing for a Long Time

    If you travel often and you sit for long periods of time, you are more prone to swelling in your lower legs. Similarly, people who stand up for prolonged periods of time can also suffer from edema.


    Swollen legs can also be caused by inflammation in the tissue. This is often the body’s natural response to injury or diseases. In some situations, swollen legs are a result of rheumatoid arthritis or other inflammatory conditions. If your pain has an inflammatory cause, you will most likely feel pain.

    Sprained Ankle

    sprained ankle occurs when you twist or turn the ankle at an awkward angle. This can either stretch or tear the ligaments that keep the ankle bones together. A sprained ankle can have different degrees of severity.

    The most common symptoms of a sprained ankle include pain and/or swelling of the foot and the leg from the knee down. It is often associated with bruising, limited motion, and a popping sensation.

    Broken Leg

    A broken leg is the result of a major trauma that creates a crack or a full break in a leg bone. It could be the result of a sports injury, falls, or vehicle collisions. This causes swelling in the leg and severe pain, especially when moving. The area is tender and bruised, and it is often impossible to walk.


    Cellulitis is an infection caused by bacteria. The affected area is swollen, red, painful, and warm to the touch. Cellulitis often affects the skin on the lower leg.


    Serious Medical Conditions


    This is a heart condition that affects the heart muscle. The heart can no longer pump blood efficiently through the entire body, which can lead to heart failure. A common symptom is swelling in legs, ankles, and feet.

    Acute Kidney Failure

    Acute kidney failure means that your kidneys cannot efficiently filter waste from your bloodstream. When this occurs, dangerous levels of waste will cause fluid buildup in several parts of your body, including your lower legs.

    This condition develops quickly over a few days, and it is common with critically ill people. Other symptoms include weakness, fatigue, shortness of breath, and decreased urine output.


    This is the late stage of a scarred liver or damaged liver. Some common symptoms include swelling in the lower legs, fatigue, easy bleeding, and bruises. Itchy skin, weight loss, and spider-like blood vessels can also be some of the common symptoms of this condition.

    Heart Failure

    Heart failure can be either acute or chronic. It starts with shortness of breath, fatigue, and weakness. It is also characterized by swollen legs, feet, or ankles.

    Lifestyle Choices

    Your lifestyle decisions can also cause edema or swollen knees or legs. For instance, being sedentary can cause swollen legs. Being overweight and obese are other leading lifestyle factors that can cause swollen legs. Lastly, wearing shoes that do not fit can cause swollen legs.
