Pedal Edema: Causes Symptoms and Treatment
Pedal Edema can be a symptom of various underlying conditions, including heart failure, kidney disease, liver disease, certain medications, venous insufficiency, or lymphatic system disorders. Identifying and addressing the underlying cause of edema is crucial for effective management and treatment.
Understanding Edema vs Pedal Edema
Edema
- Edema, the medical term for swelling, can occur in various parts of the body due to injury or inflammation.
- It may affect a small area or the entire body and can be caused by factors such as drugs, pregnancy, infections, and other medical conditions.
- Edema occurs when small blood vessels leak fluid into nearby tissues, resulting in tissue swelling and potential complications throughout the body.
Pedal Edema
- Pedal edema refers to abnormal fluid accumulation in the ankles, feet, and lower legs, leading to swelling.
- Two mechanisms can cause edema of the feet: venous edema and lymphatic edema.
- Venous edema: Increased capillary leakage causes fluid to leak into the interstitial space from the venous system.
- Lymphatic edema: Dysfunction or obstruction of lymph outflow from the legs leads to fluid accumulation in the ankles.
- These mechanisms can occur independently or together, with venous edema potentially causing lymphatic edema.
- Mild cases of foot edema are commonly caused by fluid buildup, known as edema.
- Pedal edema often results from prolonged standing or sitting in the same position for an extended period.
- Management strategies for reducing swelling include reducing salt intake, engaging in basic exercises, and elevating the feet.
- Treating underlying medical conditions is essential for alleviating pedal edema.

Get A Second OpinionWhat are the Causes of Pedal Edema?
Swelling in the feet, knees, and ankles can be caused by several factors. In most cases, the majority of the time, swelling is caused by such lifestyles such as:
Being overweight
Excessive body mass can decrease blood circulation, causing fluid accumulation in the feet, legs, and ankles.
Standing or sitting for long periods
When the muscles are inactive, they cannot pump body fluids towards the heart. Swelling in the legs can be caused by the accumulation of water and blood.
Other Causes
Other possible causes of foot, leg, and ankle swelling include certain medical conditions or body changes, such as:
- Blood clot in the leg: A blood clot is a group of blood that is in a solid state. When a blood clot forms in a vein in the leg, it can affect blood flow and cause swelling and discomfort.
- Injury or infection: An injury or infection affecting the foot, leg, or ankle causes increased blood flow to the area. This presents as swelling.
- Venous insufficiency: This condition occurs when the veins cannot pump blood properly, causing blood to pool in the legs.
- Preeclampsia: This condition causes high blood pressure during pregnancy. Increased blood pressure can cause poor circulation and swelling in the face, hands, and legs.
- Cirrhosis: This refers to severe scarring of the liver, which is often caused by alcohol abuse or an infection ( hepatitis B or C). High blood pressure and poor circulation in the feet, legs, and ankles are typical symptoms of this disorder.
What are the Symptoms of Edema?
The symptoms of edema vary depending on its severity and location in the body:
- Localized Swelling: In minor cases, such as a small area affected by an insect bite, there may be little to no noticeable symptoms. However, a more severe allergic reaction (e.g., from a bee sting) can cause significant swelling over a larger area, leading to pain and restricted movement.
- Allergic Reactions: Food allergies or reactions to medications can result in swelling of the tongue or throat. This type of edema is serious and potentially life-threatening as it can block the airway and interfere with breathing.
- Leg Edema: Swollen legs may feel heavy and make walking difficult. In cases related to conditions like heart disease, the added fluid can significantly increase the weight of each leg, sometimes by several pounds. Severe leg edema may disrupt blood circulation, potentially causing skin ulcers.
- Pulmonary Edema: This type of edema affects the lungs, leading to shortness of breath and, in some cases, low oxygen levels in the blood. It can also trigger coughing.
- Pitting vs. Non-Pitting Edema: Pressing on swollen skin in certain types of edema may leave an indentation or “pit” that persists temporarily, known as pitting edema. If the skin springs back to its normal shape, it’s referred to as non-pitting edema. These characteristics can help doctors identify the underlying cause of the swelling.
How is Pedal Edema Diagnosed?
Your doctor may order one or more of the following tests to help diagnose the cause of the swelling:
- Blood tests, including blood counts, kidney and liver function studies, and electrolytes to assess various organs
- X-rays to view bones and other tissues.
- Ultrasound to examine organs, blood vessels, and tissues.
- Electrocardiogram to assess heart function.
- If your swelling is related to a lifestyle habit or minor injury, your doctor will probably recommend home treatments. If your swelling is the result of an underlying health condition, your doctor will first try to treat that specific condition.
- The swelling can be reduced with prescription medications, such as diuretics. However, these medications can cause side effects and are usually only used if home remedies don't work.
What is the Treatment of Pedal Edema?
Treatment of pedal edema depends a lot on the cause of the edema. In certain cases, edema is curative and can be treated by stopping drugs that cause swelling of the feet. Treatment of pedal edema is done to reduce swelling by reducing capillary leakage and facilitating lymphatic drainage.

Book an AppointmentWhen to Visit a Doctor?
Most times, the swelling reduces and then disappears in 2 to 3 weeks after the body has successfully fought off the infection. If the problem persists for more than a couple of weeks, it could warrant a visit to the doctor.
Other reasons to visit the doctor include:
- A lymph node that to the touch feels stiff or rubbery
- A node that does not move freely
- A node with a diameter of an inch or more
- Swollen lymph nodes that accompany night sweats, abdominal pain, unexplained weight loss, or high fever
What are Effective Home Remedies for Pedal Edema?
Below are several home remedies that may alleviate mild pedal edema:
- Stay hydrated
- Limit sodium intake
- Elevate legs
- Gentle exercise
- Take breaks
- Apply cool compresses
- Epsom salt baths
- Wear compression socks
- Choose proper footwear
- Consistent self-care
