Swollen ankles are a common issue, often causing discomfort and concern. If you’ve noticed puffiness around your ankles, feet, or legs, you’re likely experiencing oedema. This condition, characterized by fluid buildup, is frequently temporary and resolves on its own. However, understanding why your ankles are swelling is crucial for effective management and knowing when to seek medical advice.
Common Causes of Ankle Swelling (Oedema)
Oedema occurs when excess fluid accumulates in your body’s tissues, particularly in the lower extremities due to gravity. Many factors can contribute to this fluid retention, ranging from lifestyle habits to underlying health conditions.
- Prolonged Static Positions: Sitting or standing for extended periods can hinder blood circulation, leading to fluid pooling in the ankles, feet, and legs. This is a common reason for why ankles swell after long flights or desk jobs.
- Dietary Factors: High sodium intake can cause your body to retain more water, contributing to oedema. Consuming excessive salty foods is a frequent, yet often overlooked, cause of Why Are My Ankles Swelling.
- Weight and Pregnancy: Being overweight or obese increases pressure on your veins, making it harder for blood to return to the heart and potentially causing fluid buildup. Similarly, pregnancy increases fluid volume in the body and puts pressure on the pelvic veins and inferior vena cava, both of which can contribute to swelling in the legs and ankles.
- Medications: Certain medications are known to have oedema as a side effect. These include some blood pressure medications, oral contraceptives, hormone replacement therapy, antidepressants, and corticosteroids. If you’re wondering why are my ankles swelling and are taking any of these medications, discuss it with your doctor.

- Injuries and Bites: Trauma such as a sprain or strain to the ankle or leg can trigger localized swelling as part of the body’s natural inflammatory response. Insect bites or stings can also cause swelling around the affected area.
- Underlying Medical Conditions: In some cases, persistent or sudden ankle swelling can be a symptom of more serious health issues. These conditions include kidney, liver, or heart problems, which can affect the body’s fluid balance. Blood clots in the legs can also obstruct blood flow and cause swelling in one leg. Infections, though less common, can also lead to oedema.
Recognizing Oedema: Key Symptoms
Identifying oedema is usually straightforward. The primary symptom is visible swelling in the ankles, feet, or legs. Other telltale signs include:
- Puffiness and Shiny Skin: The skin in the swollen area may appear puffy, stretched, and shiny due to the fluid accumulation underneath.

- Skin Discoloration and Discomfort: You might notice changes in skin color, such as redness or paleness. Discomfort, aching, or a feeling of heaviness in the affected limbs are also common.
- Pitting Oedema: A key characteristic of oedema is “pitting.” If you press firmly on the swollen skin for a few seconds and a dent remains after you release pressure, this indicates pitting oedema.
- Stiffness: Swollen ankles and feet can feel stiff, especially after periods of rest, making movement slightly difficult.
Self-Care Strategies to Reduce Ankle Swelling
For mild cases of ankle swelling, several self-care measures can provide relief and address why are my ankles swelling from lifestyle factors:
Recommended Actions:
- Elevate Your Legs: Whenever possible, raise your legs above your heart level. Use pillows to prop up your legs while sitting or lying down. Elevation helps gravity work in your favor, encouraging fluid to drain away from your ankles and feet.
- Gentle Exercise: Regular, low-impact exercise, such as walking or ankle pumps (flexing your feet up and down), improves blood circulation and can reduce fluid buildup.
- Wear Comfortable Footwear: Opt for wide, comfortable shoes with good support, low heels, and soft soles. Avoid tight-fitting shoes and socks that can restrict circulation.
- Foot Hygiene and Moisturizing: Maintain good foot hygiene by washing and thoroughly drying your feet daily. Moisturize your feet to prevent skin dryness and cracking, which can increase the risk of infection, especially if you have diabetes.
Actions to Avoid:
- Prolonged Standing or Sitting: Minimize extended periods of standing or sitting still. Take regular breaks to move around and stretch your legs.
- Tight Clothing: Avoid wearing tight clothing, socks, or shoes that can impede blood flow and worsen swelling.
When to Seek Medical Advice for Swollen Ankles
While self-care can manage mild oedema, it’s important to know when to seek professional medical help. Consult a General Practitioner (GP) in the following non-urgent situations:
- Persistent Swelling: If your ankle swelling doesn’t improve after a few days of home treatment.
- Worsening Swelling: If the swelling gets progressively worse over time.
Seek urgent medical attention by scheduling an urgent GP appointment or contacting NHS 111 if:
- Sudden Swelling with No Obvious Cause: If swelling appears in one ankle, foot, or leg suddenly without a clear cause like injury.
- Severe or Painful Swelling: If the swelling is significant, painful, or develops rapidly.
- Redness and Warmth: If the swollen area becomes red or feels hot to the touch, as this could indicate an infection.
- Fever or Chills: If you experience high temperature or chills along with ankle swelling.
- Diabetes and Swollen Ankles: If you have diabetes and notice swelling in your feet, ankles, or legs, it’s crucial to seek prompt medical advice.
Call 999 immediately if you experience any of the following emergency symptoms alongside swollen ankles:
- Shortness of Breath or Difficulty Breathing
- Chest Tightness, Heaviness, or Pain
- Coughing Up Blood
These symptoms may indicate a serious condition such as a blood clot in the lungs, requiring immediate hospital treatment.
Treatment for Persistent Oedema
If your ankle swelling persists or is caused by an underlying medical condition, your GP will determine the appropriate treatment. This will depend on the identified cause and may involve lifestyle modifications like weight loss or a low-sodium diet, medication adjustments, or treatment for the underlying health issue.
Understanding why your ankles are swelling is the first step towards effective management. While often benign and manageable with self-care, persistent or sudden swelling, especially when accompanied by other concerning symptoms, warrants prompt medical evaluation to ensure timely diagnosis and treatment.
