DVT is a serious condition where a bl00d clot forms in a deep vein, typically in the leg or thigh. Though the clot is not always visible, some cases may lead to prominent or bulging surface veins because of blocked blood flow.
Warning signs include:
- Sudden swelling in one leg
- Pain or tenderness, often starting in the calf
- Skin that’s red or warm to the touch
DVT is potentially life-threatening because a clot can travel to the lungs (pulmonary embolism). Immediate medical attention is required.
4. Congestive Heart Failure (CHF)
When the heart can’t pump blood effectively, pressure builds up in the veins, leading to swelling and visible veins—especially in the neck, hands, or lower extremities.
Other signs include:
- Shortness of breath
- Fatigue and weakness
- Swelling in the legs, ankles, or feet
CHF is a chronic condition that needs ongoing medical care. If you have visible veins and symptoms of heart failure, meet your doctor promptly.
5. Peripheral Vascular Disease (PVD)
PVD is a condition in which narrowed blood vessels reduce blood flow to the limbs. While arteries are primarily affected, changes in venous circulation can also cause visible veins as the body compensates by rerouting blood through smaller vessels.
Possible symptoms:
- Tired, aching legs
- Numbness or coldness in extremities
- Slow-healing wounds or color changes in the skin
PVD is often connected to atherosclerosis and may increase the risk of heart att.ack or stroke.
