Persistent swelling in the legs can reveal more than just poor circulation; know the warning signs.
Swollen legs are often related to standing for long periods, heat, or circulatory problems. In most cases, this condition is harmless and improves with rest. However, medical experts warn that persistent or unexplained swelling, especially when it affects only one leg or occurs alongside other unusual symptoms, could indicate a more serious underlying condition, such as pancreatic cancer.
Swelling in the legs is usually not caused by cancer.
Leg swelling, medically known as peripheral edema, occurs when excess fluid accumulates in the tissues. The most common causes include:
Chronic venous insufficiency
, heart disease,
kidney disorders,
liver disease,
certain medications, and
prolonged periods of sitting or standing
account for the vast majority of cases. However, doctors recommend a medical evaluation when swelling appears suddenly, worsens, or persists without an apparent explanation.
