Swollen feet can be more than just a nuisance—they often signal underlying health issues. Poor circulation, especially in those who sit or stand for long periods, can cause fluid buildup in the lower limbs, leading to swelling. Fluid retention, or edema, may result from high salt intake, hormonal shifts, or medication side effects, often manageable with lifestyle changes like leg elevation and reduced sodium.

However, persistent swelling might indicate serious conditions such as heart, kidney, or liver disease, as these organs regulate fluid balance. Swelling paired with pain, redness, or warmth could suggest infection or inflammation, while sudden swelling in one leg accompanied by tenderness may signal a dangerous blood clot requiring urgent care.

Temporary swelling can also occur due to heat, pregnancy, or prolonged standing and usually improves with gentle exercise, hydration, and compression socks.

Not all swelling is serious, but if it lasts several days or worsens, it’s important to see a healthcare professional. Early diagnosis and treatment can prevent complications and keep you moving comfortably.
