Why Blood Vessels Narrow?

Causes of peripheral vascular disease
Diabetes – high blood sugar damages and weakens blood vessels, causing them to narrow. Obstruction – a blood clot (thrombus) may lodge within the blood vessel. Infection – can cause scarring and narrowing of the blood vessels.

How do blood vessels narrow?

Vasoconstriction is narrowing or constriction of the blood vessels. It happens when smooth muscles in blood vessel walls tighten. This makes the blood vessel opening smaller. Vasoconstriction may also be called vasospasm.

Is Narrowed blood vessels bad?

A buildup of plaque can narrow these arteries, decreasing blood flow to your heart. Eventually, the reduced blood flow may cause chest pain (angina), shortness of breath, or other coronary artery disease signs and symptoms. A complete blockage can cause a heart attack.
