Dizziness and Tinnitus: A Guide for Patients

Hello, Dr. Hsu?

Hello, Dr.
Hsu! My uncle is 45 years old, and I am worried about a symptom he has.
Sometimes he experiences unexplained dizziness, a heavy sensation in his legs, and instability while standing.
His blood pressure is 160.
He eats regular meals, does not stay up late, and does not smoke or drink alcohol.
Additionally, he often experiences tinnitus.
This is the second time he has gone to the emergency room, and the doctor advised him to see a neurologist to determine if the tinnitus is causing the dizziness.
I would like to ask Dr.
Hsu: Is it possible that my uncle has hypertension? Does he need to undergo blood tests or any other diagnostic tests? Could you explain his possible symptoms? Thank you.

There are many causes of dizziness, and there are various classifications in medical theory.
However, from the perspective of patients and their families, the most pressing questions are often, "What is the condition? Will it get better?" Having worked with patients suffering from dizziness for many years, I truly empathize with their helplessness.
With today's hospital equipment, establishing a comprehensive dizziness center is not difficult; the key is to have physicians who are willing to carefully differentiate symptoms and address the underlying causes.
While larger hospitals often have dizziness centers, which may be located in either the otolaryngology or neurology departments, without physicians who can explain and differentiate symptoms carefully, even the most advanced instruments cannot provide patients with peace of mind.
Therefore, I recommend that you choose a trusted otolaryngologist or neurologist at a nearby hospital to conduct dizziness evaluations and provide explanations for your family members.
This would be the best approach to managing the situation.

More Info

Dizziness and tinnitus are symptoms that can significantly impact a person's quality of life, and understanding their potential causes is crucial for effective management. In your uncle's case, several factors need to be considered, especially given his age and the symptoms he is experiencing.

Firstly, dizziness can arise from various sources, including vestibular disorders, cardiovascular issues, neurological conditions, and even metabolic disturbances. Tinnitus, or ringing in the ears, often accompanies dizziness and can be linked to similar underlying causes. Given that your uncle has experienced episodes of dizziness, a sensation of heaviness in his legs, and tinnitus, it is essential to conduct a thorough evaluation.

High Blood Pressure Considerations:
Your uncle's recorded blood pressure of 160 mmHg is indicative of hypertension, which can contribute to dizziness. High blood pressure can affect blood flow to the brain, leading to symptoms like dizziness and even fainting in severe cases. It is essential to monitor his blood pressure regularly and manage it effectively, as uncontrolled hypertension can lead to more severe complications, including stroke.

Potential Causes of Symptoms:
1. Vestibular Disorders: Conditions such as benign paroxysmal positional vertigo (BPPV), vestibular neuritis, or Meniere's disease can cause dizziness and tinnitus. These disorders affect the inner ear, which is crucial for balance and hearing.

2. Neurological Issues: Migraines, particularly vestibular migraines, can present with dizziness and tinnitus. Other neurological conditions, such as multiple sclerosis or transient ischemic attacks (TIAs), could also be considered, especially if there are additional neurological signs.

3. Cardiovascular Problems: Apart from hypertension, other cardiovascular issues, such as arrhythmias or heart disease, can lead to dizziness due to inadequate blood flow to the brain.

4. Metabolic or Endocrine Disorders: Conditions like anemia, diabetes, or thyroid dysfunction can also manifest as dizziness and should be evaluated through blood tests.

Recommended Evaluations:
1. Blood Tests: A complete blood count (CBC) to check for anemia, metabolic panel to assess kidney and liver function, and thyroid function tests can provide valuable information about his overall health.

2. Imaging Studies: Depending on the findings from the initial evaluations, imaging studies such as an MRI or CT scan of the brain may be warranted to rule out any structural abnormalities.

3. Vestibular Testing: If a vestibular disorder is suspected, specialized tests such as electronystagmography (ENG) or videonystagmography (VNG) can help assess inner ear function.

4. Cardiovascular Assessment: An electrocardiogram (ECG) and possibly an echocardiogram may be necessary to evaluate heart function and rhythm.

Management Strategies:
Once a diagnosis is established, management will depend on the underlying cause. If hypertension is confirmed, lifestyle modifications such as dietary changes, regular exercise, and possibly medication will be crucial. For vestibular disorders, vestibular rehabilitation therapy may be beneficial. If the tinnitus is bothersome, sound therapy or cognitive behavioral therapy may help alleviate the distress associated with it.

In conclusion, your uncle's symptoms warrant a comprehensive evaluation by a healthcare professional, particularly a neurologist or an ear, nose, and throat (ENT) specialist. Early diagnosis and intervention can significantly improve his quality of life and prevent potential complications. Encourage him to follow up with his healthcare provider and discuss his symptoms in detail to ensure he receives the appropriate care.
