Lightheadedness and dizziness can be symptoms of various medical conditions, including serious heart and brain issues. According to the American Stroke Association, these symptoms may signal problems like atrial fibrillation (AFib), cardiomyopathy, or certain types of strokes.
What Causes Lightheadedness?
Dr. Mitchell S. V. Elkind, a neurologist and chief clinical science officer of the American Heart Association, explains that lightheadedness can occur when blood flow to the brain is insufficient.
This may happen due to conditions like AFib, the most common heart rhythm disorder, or cardiomyopathy, a disease of the heart muscle that weakens its ability to pump blood effectively. Both conditions increase the risk of stroke and require continuous medical monitoring and treatment adjustments.
However, not all episodes of lightheadedness are severe. Common causes include dehydration, viral infections, or other minor issues. Dr. Elkind advises that any unusual symptoms, particularly those that are sudden or severe, should be reported to a doctor immediately.
A Real-World Example: Senator John Fetterman
Senator John Fetterman’s recent hospitalization underscores the importance of vigilance with such symptoms. After feeling lightheaded on February 8, he was taken to a hospital in Washington, D.C., where initial tests ruled out a new stroke.
The senator, who suffered a stroke last year, has been open about his diagnosis of AFib and cardiomyopathy. Both conditions require careful management to prevent complications like stroke.
Recognizing Stroke Symptoms
Stroke is the fifth leading cause of death and a major cause of disability in the United States, according to the American Stroke Association. It can affect anyone, regardless of age or lifestyle. Prompt recognition and treatment are crucial for better outcomes.
The American Stroke Association uses the acronym F.A.S.T. to help people recognize common stroke symptoms:
- F = Face Drooping: Look for unevenness in the face.
- A = Arm Weakness: Check if one arm is weak or numb.
- S = Speech Difficulty: Listen for slurred or strange speech.
- T = Time to Call 911: Act immediately if you see any of these signs.
Additional symptoms to watch for include:
- Sudden numbness or weakness, especially on one side of the body.
- Sudden confusion or difficulty understanding speech.
- Sudden trouble seeing in one or both eyes.
- Sudden difficulty walking, dizziness, or loss of balance.
- Sudden, severe headache with no known cause.
The Importance of Seeking Help
If someone experiences any of these symptoms, calling 911 right away is essential. Emergency responders can begin treatment even before reaching the hospital, potentially saving lives and reducing long-term damage.
Dr. Elkind shared these insights at the International Stroke Conference, a major event dedicated to stroke and brain health. As he noted, conditions like AFib and cardiomyopathy are treatable, but they require ongoing care and monitoring.
Symptoms like lightheadedness should never be ignored, as they might signal a need for adjustments in treatment or further medical intervention.
The American Stroke Association emphasizes the need for public awareness of stroke risks and symptoms. Knowing what to look for and acting quickly can make a life-saving difference.
If you care about stroke, please read studies that diets high in flavonoids could help reduce stroke risk, and MIND diet could slow down cognitive decline after stroke.
For more health information, please see recent studies about antioxidants that could help reduce the risk of dementia, and tea and coffee may help lower your risk of stroke, dementia.
