Carotid Stenosis: Causes, Symptoms, and Treatments to Prevent Strokes
Carotid stenosis, a narrowing of the carotid arteries, is a serious health concern. It can lead to strokes, affecting nearly 800,000 Americans annually. Understanding its causes, symptoms, and treatments is crucial.
Carotid stenosis occurs due to atherosclerosis, a buildup of deposits in the carotid arteries. Risk factors include smoking, high cholesterol, hypertension, diabetes, and a family history of cardiovascular disease. As plaque increases, so does the stroke risk.
Symptoms of a stroke caused by carotid stenosis range from transient blindness and slurred speech to weakness, numbness, confusion, and loss of consciousness. Diagnosis involves a physical exam and imaging tests like ultrasound, CTA, or MRA.
Treatment varies depending on the severity. Mild cases can be managed with aspirin or other antiplatelet medications. Severe blockages may require surgical treatment via carotid endarterectomy. Managing underlying causes, such as quitting smoking and controlling blood pressure and cholesterol, is vital to prevent complications.
Carotid stenosis is a significant risk factor for strokes. Understanding and managing its causes and symptoms can help prevent serious health issues. If you have risk factors, consult your healthcare provider for regular check-ups and appropriate care.
