Carotid arteries play a crucial role in the function of the brain, as they are responsible for providing blood and oxygen to the organ. With carotid stenosis, the flow of blood can become blocked, which can eventually result in a stroke if left untreated.
Many people with carotid stenosis also have a condition called atherosclerosis. This condition occurs when the arteries and arterial walls are clogged with fats and cholesterol, which develop plaque. As the plaque develops, it can narrow the interior of the arteries.
Certain risk factors can increase your chance of experiencing atherosclerosis, which in turn can lead to carotid stenosis. These risk factors include:
It is often possible to decrease your chance of carotid stenosis by understanding your unique risks and taking the proper steps to mitigate them.
Along with lifestyle changes, carotid stenosis can also be treated with medication. For instance, medications can help you manage cholesterol levels, prevent blood clots, and decrease blood pressure.
In the event you have a more severe form of carotid stenosis, surgery may be recommended to lower your chances of experiencing a stroke. Surgeries are usually performed when the carotid arteries experience a narrowing of over 70%.
