A carotid artery stenosis refers to the narrowing of the carotid arteries and diagnosis of which may be given
by your physician after a complete physical examination. A bruits which is a rumbling or swishing sound may
be heard over the neck when your physician auscultates or listens to the area with his stethoscope. A carotid
duplex scan may also be able to help assess how narrow the carotid vessels are.
In most cases, stenosis may not present with any symptoms. Dizziness may be noted for some patients. However
lightheadedness and the easy fatigability you have mentioned are nonspecific symptoms.

You need to be further evaluated here. A complete cardiac work up including an EKG, 2D echo and stress test as
well as blood tests for blood sugar and cholesterol levels are important.
