A thickening of the neck for no apparent reason? Your body is sending you a message that shouldn’t be ignored.

Although usually painless, this symptom can indicate a more serious problem, particularly with your circulatory system. Surprisingly, this small, sometimes subtle sign can be one of the first symptoms of a potential heart condition.

Why do we observe this swelling in the neck area?

Several factors can explain this venous protrusion, most of which are related to impaired cardiac function:

A weakening heart: When the right ventricle struggles to pump blood effectively, it can pool in the veins, causing the characteristic swelling in the neck.
High pulmonary pressure: This creates a blood congestion, slowing venous return to the heart.
