Swollen feet can be caused by various factors, and while most cases can be addressed by resting or elevating the feet, sudden or unexplained swelling may indicate an underlying health issue. If you’re experiencing persistent or severe swelling, it’s important to consult a medical professional to rule out serious conditions.

Causes of Swollen Feet

1. Deep Vein Thrombosis (DVT)
DVT is a condition where a blood clot forms in the deep veins, often in the legs. Along with swelling, you might experience heaviness or discomfort in the legs. DVT can be dangerous as it can lead to a pulmonary embolism if the clot moves to the lungs, blocking blood flow. Seek medical attention immediately if you suspect DVT.

2. Achilles Tendonitis
Achilles tendonitis occurs when the Achilles tendon becomes inflamed, often after physical activities. This can lead to swelling in the ankles and heels. Pain and difficulty moving the foot are common signs. Treatment typically involves rest and physical therapy.

3. Osteoarthritis
Osteoarthritis is the most common type of arthritis and can cause swelling, pain, and stiffness in the joints, including those in the feet. While it can be managed through medication, exercise, and lifestyle changes, it’s important to consult a doctor for a proper diagnosis.

4. Heart Failure
In cases of heart failure, the heart is unable to pump blood effectively, leading to fluid buildup in the body, often in the feet, ankles, and legs. This condition, known as edema, is common in heart failure patients and requires medical management.

5. Lymphedema
Lymphedema occurs when excess lymphatic fluid accumulates in the limbs, causing swelling. It is important to seek medical attention if you experience sudden or severe swelling in your legs, as untreated lymphedema can worsen over time.
