Your carotid artery supplies the brain with blood, oxygen and nutrients. This artery can become blocked due to age, heredity and unhealthy lifestyle behaviors. This condition is called atherosclerosis. It's a serious condition that can be fatal. Your best defense is to have your blood pressure and cholesterol checked regularly. This way, you can detect and treat heart disease before it gets worse. It's also important to be aware of the common signs and symptoms of this condition.
Common Symptoms
The Texas Heart Institute says there are often no symptoms of this disease until a problem occurs. However, in some cases, you may experience a sudden and severe headache, trouble swallowing and vision changes. You may also feel dizzy and suffer fainting spells. Another warning sign is if you feel numbness in any area of your body.
Additional Signs
The Mayo Clinic claims you and your doctor may not know you have this disease until the brain is deprived of oxygen. This can lead to what is called a TIA, or transient ischemic attack. It's sometimes referred to as a "mini stroke," because it causes the same symptoms as a stroke. However, there is no permanent damage. Call an ambulance if you notice symptoms such as paralysis or weakness on one side of the body, slurred speech, difficulty understanding speech, confusion or appearing to be "out of it" for a brief period.
Severe Signs
According to the University of Michigan, the first sign of a blocked carotid artery that has gone untreated may be a stroke. A stroke can be mild or deadly. Signs of a stroke are the same as all of the above. However, a stroke can cause permanent damage. In addition, be on the lookout for drowsiness, nausea or vomiting. If your condition is caught early enough, you can have surgery to prevent a stroke.
