Swelling in the feet, also known as oedema, is a common condition that can cause discomfort and concern. It’s often characterized by a noticeable puffiness in your feet and ankles, sometimes extending up to the legs. While foot swelling often resolves on its own, understanding the causes and knowing effective remedies can help you manage it better. This article will guide you through the common causes of swollen feet, provide practical steps on how to reduce swelling at home, and advise you on when it’s crucial to seek medical attention.
Understanding Swelling in Feet (Oedema)
Oedema occurs when excess fluid builds up in your body’s tissues, frequently affecting the feet, ankles, and legs due to gravity. Recognizing the symptoms and potential causes is the first step towards effective management.
Common Causes of Swollen Feet
Several factors can contribute to fluid retention and swelling in the feet. Many are lifestyle-related or temporary, while others may indicate underlying health conditions. Common causes include:
- Prolonged Standing or Sitting: Staying in the same position for extended periods can hinder circulation, leading to fluid accumulation in the lower extremities.
- High Salt Intake: Consuming excessive sodium can cause your body to retain more water, contributing to swelling.
- Being Overweight or Obese: Excess weight can put strain on your circulatory system and increase the risk of oedema.
- Pregnancy: Hormonal changes and increased pressure on veins during pregnancy are common causes of swollen feet and ankles.
- Medications: Certain drugs, including some blood pressure medications, birth control pills, hormone replacement therapy, antidepressants, and steroids, can have oedema as a side effect.
- Injury: Sprains, strains, or fractures in the foot or ankle can trigger swelling as part of the body’s natural healing process.
- Insect Bites or Stings: Reactions to insect bites or stings can cause localized swelling.
- Underlying Health Conditions: Swelling in the feet can sometimes be a symptom of more serious conditions related to the kidneys, liver, or heart, which affect fluid balance and circulation.
- Blood Clots: A blood clot in the leg can obstruct blood flow and cause sudden swelling in one leg.
- Infection: Infections in the foot or leg can also lead to swelling, often accompanied by redness and pain.

Symptoms of Swollen Feet
Identifying oedema involves recognizing key symptoms in your feet, ankles, or legs:
- Visible Swelling or Puffiness: This is the most obvious sign, where your feet and ankles appear larger than usual.
- Shiny or Stretched Skin: The skin in the swollen area may look tight, shiny, or stretched due to the fluid underneath.
- Skin Discoloration: Changes in skin color, such as redness or paleness, may occur in the swollen area.
- Discomfort or Heaviness: Your feet and legs may feel heavy, achy, or uncomfortable.
- Stiffness: Swelling can sometimes lead to stiffness in the joints of the feet and ankles.
- Pitting Oedema: If you press your finger on the swollen skin and it leaves a dent that takes a few seconds to disappear, this is known as pitting oedema and is a characteristic sign of fluid retention.

Effective Ways to Reduce Swelling in Feet at Home
For mild to moderate swelling, several self-care strategies can help alleviate discomfort and reduce fluid retention in your feet.
Simple Home Remedies
- Elevate Your Legs: When resting, raise your legs above your heart level using pillows or a chair. This promotes fluid drainage back towards the heart.
- Gentle Exercise: Light activities like walking or ankle pumps can improve blood circulation and help reduce swelling. Regular movement prevents fluid from pooling in your feet and ankles.
- Wear Compression Socks or Stockings: These garments apply gentle pressure to your legs and feet, helping to improve blood flow and reduce swelling.
- Reduce Salt Intake: Limiting your consumption of salty foods can help your body retain less water and decrease swelling.
- Stay Hydrated: Drinking plenty of water helps your kidneys flush out excess sodium and fluids from your body, which can reduce oedema.
- Wear Comfortable Footwear: Opt for wide, comfortable shoes with good support and low heels. Avoid tight shoes or high heels that can restrict circulation.
- Foot Massage: Gently massaging your feet and ankles can help improve lymphatic drainage and reduce fluid buildup. Start from your toes and move upwards towards your legs.
- Cool Compresses: Applying cool, damp cloths to your swollen feet can provide soothing relief and help reduce inflammation.
- Wash, Dry, and Moisturize Feet: Maintaining good foot hygiene is important to prevent skin infections, especially when swelling is present. Gently wash and thoroughly dry your feet daily, and apply moisturizer to keep the skin supple.
What to Avoid
Certain habits can worsen foot swelling and should be avoided:
- Prolonged Standing or Sitting: Try to take breaks and move around every 30 minutes if you need to stand or sit for long periods.
- Tight Clothing and Footwear: Avoid wearing tight socks, stockings, or shoes that can restrict blood flow and exacerbate swelling.
