You may sometimes experience dizziness and you think it is normal. But a dizzy feeling may be a sign of strokes. Do you know this information? Let’s find out when dizziness shows that you have a high risk for strokes.
Dizziness may be a warning sign of strokes
Dizziness is a kind of feeling. It is not always the same to everyone. Dizziness is a complaint and the most common causes are mild but it can be the sign of underlying diseases. Dizziness is considered to have 4 types, including:
- Vertigo: you feel that you move when there is no motion. For example, you think that you are spinning or the environment is spinning. After you stop spinning yourself round and round, you may experience temporary vertigo. But if it appears when you are not doing that, this may be a sign of a problem with the balance system in the inner ear.
- Lightheadedness: when it occurs, you may feel that you are about to faint. You may experience lightheadedness when you stand up too quickly.
- Disequilibrium: this is the feeling that you are going to fall.
- Anxiety: in this case, you may feel scared, worried, depressed.
Dizziness may be a warning sign that your brain is not supplied with adequate blood. Sometimes blood vessels expand or become dilated, you may experience lightheadedness.
In a mini-stroke, blood that flows to the brain is blocked for a short time. It is a warning sign of a future stroke. In an ischemic stroke, the artery carrying blood is blocked.
Many studies have shown that people who experience dizziness may have higher chances of getting a stroke.
Tests to confirm a stroke
Although dizziness may be a warning sign of stroke, it is not easy to give a diagnosis of stroke in patients with dizziness, and other accompanying symptoms such as vomiting, numbness, weakness, having difficulty walking or speaking .
When you see a doctor, he or she will ask about your family history and medical history, your symptoms and the medications that you are taking. Then, he or she will check your blood pressure, and use a special device to check listening to your heart. Several blood tests may be recommended to analyze the ingredients of your blood. Brain scan such as CT scan or MRI can be used to provide detailed images of your brain.
Other causes of dizziness
As told, sudden dizziness could signify that you have an increasing risk of stroke. However, not only can stroke cause dizziness, but other conditions can lead to this term of feelings.
- Infection such as common cold, diarrhea, or ear infection
- Meniere’s disease
- Dandy’s syndrome
- Arthritis such as cervical spondylosis
- Diseases such as diabetes

Thus, it is important to seek medical attention as soon as possible if you experience sudden severe dizziness. This may help you prevent a future stroke, or at least common but serious health problems listed above.
