The ankles often act as an early indicator of what’s happening inside the body. The pattern of swelling—whether it is one-sided or symmetrical—can reveal whether the problem lies in the veins or the heart. Knowing these differences is vital for seeking timely medical help before complications arise.Pitting edema occurs when pressing on the swollen area leaves a temporary indentation. This type of swelling in one leg may indicate deep vein thrombosis, a condition where blood clots obstruct deep veins. Symptoms often include pain, warmth, and redness in the affected limb. Immediate medical attention is critical, as untreated DVT can lead to pulmonary embolism, a life-threatening complication where a clot travels to the lungs.When swelling occurs in both legs simultaneously, it may point to heart failure. This condition prevents the heart from pumping blood efficiently, causing fluid retention in tissues. Other signs can include shortness of breath, fatigue, and rapid weight gain. Early diagnosis and treatment are essential to prevent complications such as organ damage or severe fluid accumulation in the lungs (pulmonary edema).
Any sudden or persistent swelling in the legs, especially when accompanied by pain, warmth, or shortness of breath, warrants prompt medical evaluation. Doctors may recommend ultrasound scans, blood tests, or heart function assessments to determine the cause and initiate treatment.
