*Jugular vein distention (JVD)** is the visible bulging of veins in the neck, often signaling serious heart or circulation problems like right-sided heart failure, pulmonary hypertension, or valve issues.
It’s not painful but can accompany symptoms like fatigue, swelling, nausea, or confusion.
JVD itself isn’t harmful, but it indicates an underlying condition that needs medical treatment, which varies from medication to surgery.
You should never try to treat JVD at home—it requires professional diagnosis and care.
