Carotid artery stenosis - self-careCarotid artery disease - self-care
The carotid arteries provide the main blood supply to the brain. They are located on each side of your neck. You can feel their pulse under your jawline.
Carotid artery stenosis occurs when the carotid arteries become narrowed or blocked. This can lead to stroke.
Whether or not your doctor recommended surgery to unblock narrowed arteries, medicines and lifestyle changes can:
- Prevent further narrowing of these important arteries
- Prevent a stroke from occurring
Making certain changes to your diet and exercise habits can help treat carotid artery disease. These healthy changes can also help you maintain a healthy weight and manage high blood pressure and cholesterol.

These medicines can have side effects. If you notice side effects, be sure to tell your doctor. Your doctor may change the dose or type of medicine you take to help reduce side effects. Never stop taking medicines or take less medicine without talking to your provider first.
Your provider will want to monitor you and see how well your treatment is working. At these visits, your provider may:
- Use a stethoscope to listen to the blood flow in your neck
- Check your blood pressure
- Check your cholesterol levels
You may also have imaging tests done to see if the blockages in your carotid arteries are becoming worse.
When to Call the Doctor
Having carotid artery disease puts you at risk for stroke. If you think you have symptoms of stroke, go to the emergency room or call 911 or the local emergency number immediately. Symptoms of a stroke include:
- Blurred vision
- Loss of memory
- Loss of sensation
- Problems with speech and language
- Vision loss
- Weakness in one part of your body
Get help as soon as symptoms occur. The sooner you receive treatment, the better your chance for recovery. With a stroke, every second of delay can result in more brain injury.
