Dizziness Is Not a Minor Issue! 3 Causes of "Dizziness" You May Never Have Known
Dizziness may be caused by anemia, low blood pressure, or cerebral artery stenosis. Even if CT and MRI are normal, hidden risks may still exist. Learn the causes and prevention methods before it's too late.
Case 1: Dizziness from "Anemia" (Low Red Blood Cells)
A 66-year-old female patient presented with chronic dizziness for 4 months. Examination revealed very pale hands and a low red blood cell count, or anemia.
When the body lacks sufficient iron, it produces fewer red blood cells, resulting in poor oxygen delivery to the brain. This causes symptoms like dizziness, easy fatigue, and heart palpitations.
Foods that help boost iron
One of the local foods high in iron is Turkey Berry (Ma-kheua Phuang), which contains iron that the body can easily use to build red blood cells, thereby helping to reduce dizziness caused by anemia.
However, if you experience paleness and easy fatigue, a blood test is recommended to determine the actual cause.
Case 2: Post-Meal Dizziness from Low Blood Pressure and Low Water Intake
A 33-year-old female patient suffered from chronic dizziness, especially after meals. Her blood pressure was found to be low at 85/50.
During cold weather, many people drink less water. When the body is dehydrated, blood circulation worsens. Additionally, after eating, more blood flows to the stomach for digestion, reducing blood supply to the brain and causing dizziness.
Simple solutions:
• Drink more than 2 liters of water per day.
• Exercise regularly to improve heart efficiency.
Case 3: Dizziness from Cerebral Artery Stenosis—Despite Normal CT and MRI Results
A 71-year-old male patient experienced chronic dizziness for 1 year. CT and MRI scans showed no abnormalities in the brain tissue.
However, a vascular ultrasound revealed that the main artery supplying blood to the brain (Internal Carotid Artery) was completely blocked. Out of 4 cerebral arteries, 2 were blocked, 1 was narrowed (stenosis), leaving only 1 functioning properly.
Important Note:
Normal CT and MRI results do not mean "normal cerebral blood vessels" because these scans only show the brain tissue, not the narrowing of the blood vessels.
In this case, antiplatelet medication must be administered immediately, and blood pressure, diabetes, and cholesterol must be strictly controlled. If more arteries become blocked, it could lead to death or a persistent vegetative state (sleeping prince).
Conclusion
The causes of dizziness are very broad, ranging from:
• Anemia
• Low blood pressure
• To cerebral artery stenosis
If symptoms do not improve or become chronic, a detailed examination should be conducted—especially a cerebral vascular evaluation—to prevent a stroke before paralysis occurs.
Because if you end up saying, "If only I had known,"
it means you have already missed the chance to prevent it.
