Is blurred vision a warning of stroke risk?

GĐXH - Blurred vision can be a potential symptom or early sign of a stroke.

According to MSc. Dr. Pham Thi Thuy - Stroke Center, Phu Tho General Hospital, blurred vision can be a potential symptom or early sign of stroke , especially when combined with other symptoms.

Why is blurred vision related to stroke?

According to Dr. Thuy, blurred vision can warn of the risk of stroke for the following reasons:

Due to blockage of blood vessels in the brain

One of the most common causes of stroke is when the blood vessels supplying blood to the brain become blocked, leading to a lack of oxygen and nutrients in the brain. If the blockage occurs in areas of the brain involved in visual function, it can cause blurred vision or partial vision loss.

Hemorrhagic stroke

When a blood vessel in the brain ruptures, blood leaks into surrounding areas, which can increase pressure on brain tissue and affect vision. This condition can also lead to blurred vision or loss of vision.

Affects brain regions involved in vision

Areas of the brain that control vision (such as the visual cortex at the back of the brain) can be damaged by a stroke. This can cause blurred vision in one or both eyes.

4 factors that increase the risk of stroke are related to blurred vision

High blood pressure (hypertension): This is one of the major risk factors for stroke. High blood pressure can increase the risk of blood vessels in the brain bursting or blood clots forming.

Cardiovascular disease : Heart problems, such as arrhythmias (heart rhythm disturbances), can create blood clots that travel to the brain, blocking blood vessels in the brain.

Diabetes : People with diabetes are at increased risk of blood vessel problems and stroke.

Smoking and drinking alcohol : These unhealthy habits increase the risk of blood vessel blockage, contributing to an increased chance of stroke.

How to prevent stroke when there are signs of blurred vision

According to MSc. Dr. Pham Thi Thuy, not everyone clearly understands stroke and its signs. Some people think that stroke only happens to the elderly or people with underlying diseases, so they do not think that they can get it.

In fact, many people, when experiencing blurred vision, subjectively assume that it is an eye problem such as nearsightedness, conjunctivitis, or other problems, without realizing that it could be a sign of a stroke.

Confusion between blurred vision due to stroke and eye diseases is a common problem and subjectivity can lead to serious consequences, causing patients to lose the opportunity for early treatment or leaving severe sequelae.

So, if you or a loved one experiences sudden blurred vision, especially if it's accompanied by symptoms like muscle weakness, difficulty speaking, or loss of balance, go to the hospital immediately for emergency treatment.
