Your legs and feet can reveal more about your health than you think, says doctor |
When we’re hit with a major health crisis, it’s rarely out of the blue. The body almost always sends early warnings, subtle signals that something deeper is brewing. The trick lies in noticing them and acting before it’s too late.Dr. Kunal Sood, MD, explained in a recent Instagram post that the lower body, our legs and feet, often provides early clues about heart, kidney, or circulatory problems. Yet, many people overlook these signs or dismiss them as normal fatigue or aging. Paying attention, he says, could make a critical difference to your long-term health.Changes in your lower limbs often signal what’s happening inside your heart, vessels, or circulation. Here’s what each clue can mean:These are often varicose veins, dilated, twisted superficial veins caused by weakened valves and poor venous return. They appear as bluish or bulging lines along the legs or feet. According to the CEAP classification, visible, tortuous veins are a hallmark of C2-stage varicose vein disease. Over time, they can lead to heaviness, aching, and skin discoloration if left untreated.
Persistent swelling in both ankles may relate to heart, kidney, or liver issues, or sometimes pregnancy. Bilateral swelling often develops when circulation slows or venous pressure rises. Chronic venous disease can cause heaviness, aching, and edema that worsen with prolonged standing or sitting. If the swelling doesn’t resolve with rest, medical evaluation is essential.
Cold, pale feet with pain on walking
This combination often points to poor circulation from Peripheral Arterial Disease (PAD). Narrowed arteries restrict blood flow, making feet feel cool or look pale. Pain or cramping during walking, known as intermittent claudication, is a classic sign. Left unmanaged, PAD can progress to serious complications like non-healing wounds or tissue loss.
Calf red, hot, and swollen
A red, swollen, and warm calf can signal a deep vein thrombosis (DVT), a blood clot in a deep vein. Warning signs include one-sided tenderness, redness, and swelling due to venous obstruction. Risk factors include prolonged immobility, trauma, cancer, pregnancy, or inherited clotting disorders. Since DVT can lead to life-threatening pulmonary embolism, prompt medical attention is crucial.
Sores on toes or ankles that don’t heal
Non-healing ulcers on the toes, feet, or ankles often stem from poor blood flow due to advanced PAD. Reduced circulation deprives tissues of oxygen, delaying healing and increasing infection risk. Such ulcers are red flags for severe vascular disease and, if untreated, can progress to gangrene or limb loss.Disclaimer: This article is for informational purposes only and should not be considered medical advice.
