Blockage of neck arteries due to injury
Injury to neck arteries, such as a tear in the carotid or vertebral artery, can rapidly block blood supply to the brain, leading to stroke, according to Times of India. Accidents, forceful twisting during yoga, or even a severe cough can damage blood vessel walls, forming clots that obstruct blood flow. Patients often experience a severe headache and neck pain, followed by muscle weakness and blurred vision within hours.
Heart problems
A patent foramen ovale (PFO), a hole in the heart, allows blood clots to travel from veins to brain arteries, increasing stroke risk. Many individuals overlook rapid heartbeats during exercise or work, only discovering a PFO during routine health examinations.
Prolonged high blood sugar
Consistently high blood sugar damages the entire body, including the brain, according to Eatingwell. This condition stiffens arteries, making them less elastic, which reduces blood flow or leads to blockages, thereby increasing stroke risk.
The link between diabetes and stroke stems from how the body processes glucose for energy, states the American Heart Association. Uncontrolled diabetes results in consistently high blood sugar, which negatively impacts blood vessels over time. This damage can lead to the formation of fatty plaques or blood clots, obstructing blood flow to the brain, causing oxygen deprivation and ultimately, stroke.
If you have diabetes or are at risk, monitor your blood sugar levels as your doctor advises. Additionally, reduce your consumption of sugary drinks, desserts, and processed snacks.
High blood pressure
High blood pressure is a leading cause of stroke. Over time, it damages and weakens blood vessel walls, making them susceptible to blockage or rupture, which can result in ischemic or hemorrhagic stroke. If your blood pressure consistently measures 130/80 or higher, consult your doctor about treatment options, according to WebMD.
Smoking increases stroke risk because nicotine raises blood pressure. Tobacco smoke also contributes to fat buildup in the main neck arteries, making blood more prone to clotting.
