Dizziness
Hello Doctor: I have been experiencing dizziness since April.
I consulted a physician who prescribed medication for vertigo, and they also checked my white blood cell count, anemia, and liver function.
Aside from anemia, which was found to be 12.2, everything else was normal.
However, the medication caused palpitations, so I stopped taking it.
Now, in May, my dizziness has not improved; in fact, the frequency and duration of the dizziness have increased.
I feel a heavy sensation in my head, and sometimes I also feel nauseous.
Recently, I have also been experiencing dry mouth.
Doctor, could you please explain what might be causing these symptoms? How can I improve my condition? What tests should I undergo, and which specialty should I consult? Thank you, Doctor!

Hello: The symptom of dizziness can be indicative of various diseases, such as lesions in the brain's balance nerves or brainstem, or other intracranial pathologies.
It may also be caused by issues with the eighth cranial nerve, commonly known as vestibular nerve degeneration or inflammation.
Additionally, it could stem from systemic diseases affecting cardiac function, thyroid function, liver function, or blood disorders.
If a series of examinations reveal no issues, it is essential to consider whether it may be due to autonomic nervous system dysfunction.
Since you have experienced these symptoms for five months, it is advisable to consult a neurologist to rule out intracranial diseases and undergo further evaluation.
The neurologist will determine whether to arrange for neurophysiological studies, a CT scan, or MRI of the brain based on your symptoms.
I hope this response is helpful to you, and I wish you good health.
Thank you.

More Info
Dizziness can be a complex symptom with a variety of potential causes, and understanding its underlying mechanisms is crucial for effective treatment. Based on your description, it seems that you have been experiencing dizziness since April, which has progressively worsened. You mentioned that you were prescribed medication for vertigo, but you experienced side effects such as palpitations, leading you to discontinue its use. Additionally, you noted feelings of heaviness in your head, nausea, and dry mouth, which can further complicate the clinical picture.
Potential Causes of Dizziness
1. Vestibular Disorders: Conditions affecting the inner ear, such as benign paroxysmal positional vertigo (BPPV), vestibular neuritis, or Meniere's disease, can lead to episodes of dizziness or vertigo. These disorders often present with a spinning sensation and may be triggered by changes in head position.
2. Neurological Issues: Dizziness can also arise from neurological conditions, including migraines, multiple sclerosis, or transient ischemic attacks (TIAs). Migraines, in particular, can cause vestibular symptoms, including dizziness and nausea.
3. Cardiovascular Factors: Orthostatic hypotension (a drop in blood pressure upon standing) can lead to dizziness, especially if you have been experiencing anemia, as indicated by your hemoglobin level of 12.2. Anemia can reduce the oxygen supply to the brain, contributing to dizziness and fatigue.
4. Dehydration and Electrolyte Imbalance: Dry mouth and increased dizziness could suggest dehydration or an electrolyte imbalance, which can occur due to inadequate fluid intake or excessive loss of fluids.
5. Medication Side Effects: As you experienced palpitations from the dizziness medication, it's essential to consider that other medications or supplements you may be taking could also contribute to dizziness.
Recommended Investigations
Given the complexity of your symptoms, a thorough evaluation is necessary. Here are some recommended steps:
1. Blood Tests: A complete blood count (CBC) to assess for anemia, along with tests for electrolytes, kidney function, and thyroid function, can provide insights into potential underlying causes.
2. Imaging Studies: Depending on your physician's assessment, imaging studies such as an MRI or CT scan may be warranted to rule out any structural issues in the brain or inner ear.
3. Vestibular Testing: If a vestibular disorder is suspected, specialized tests such as a caloric test or electronystagmography (ENG) may help evaluate inner ear function.
4. Cardiovascular Assessment: Monitoring your blood pressure in different positions (lying down, sitting, standing) can help identify orthostatic hypotension.
Treatment Options
1. Lifestyle Modifications: Increasing fluid intake, ensuring adequate hydration, and maintaining a balanced diet can help manage symptoms. If dehydration is a concern, consider electrolyte solutions.
2. Physical Therapy: Vestibular rehabilitation therapy (VRT) can be beneficial if a vestibular disorder is diagnosed. This therapy involves exercises designed to improve balance and reduce dizziness.
3. Medication Review: Discuss with your physician the possibility of adjusting your current medications or trying alternative treatments that may have fewer side effects.
4. Follow-Up Care: Regular follow-up appointments with your healthcare provider are essential to monitor your symptoms and adjust treatment as necessary.
When to Seek Further Help
If your dizziness worsens, or if you experience additional symptoms such as severe headache, visual disturbances, weakness, or difficulty speaking, seek immediate medical attention. These could be signs of a more serious condition requiring urgent evaluation.
In summary, dizziness can stem from various causes, and a comprehensive approach involving medical evaluation, lifestyle changes, and possibly physical therapy can help manage your symptoms effectively. It is advisable to consult with a healthcare provider, preferably an internist or a neurologist, to explore these options further and tailor a treatment plan specific to your needs.
