Dizziness from Neck Vessel Blockage: Causes and Treatments

Dizziness caused by posterior cervical vascular occlusion?

Dear Dr.
Yeh,
My mother is 72 years old and has been suffering from dizziness (mostly a feeling of heaviness rather than true vertigo) for over ten years.
During this time, she has endured a lot of suffering and has seen many doctors.
Some have suggested it is due to neurological imbalance, while others have said it is due to neurodegeneration, leading to conflicting opinions.
The medications prescribed initially seemed effective, but after a while, they lost their efficacy.
A year ago, she underwent an examination at Taichung Veterans General Hospital's neurology department, where they indicated that the blood vessels at the back of her neck are 50% blocked, and that poor basilar circulation is the cause of her dizziness.
However, after taking the prescribed medication for several months, there was no improvement.
She has now visited the ENT department at St.
Mary’s Hospital in Chiayi, and after taking the medication for a month, it seems to be somewhat effective.
However, after just two days without the medication, the dizziness returned.
When she asked the doctor if there is any possibility of a cure, the doctor said it is not possible.
I would like to ask Dr.
Yeh two questions:
(1) Is vascular blockage really the main cause of her dizziness? Is it truly impossible for medication to clear this blockage? Will her condition continue to worsen?
(2) I have heard that drinking more water can help improve vascular blockage.
Is this true?
I would greatly appreciate your clarification on these matters.
I have carefully reviewed related questions from others and found none similar.
Sincerely,
A concerned son, Yeh Han-Jun

1.
Posterior circulation obstruction is a common cause of dizziness.
2.
Atherosclerosis is the primary cause of the obstruction and is often irreversible.
3.
Long-term medication should improve the condition and also has a preventive effect against stroke.

Dear Mr. Yeh,
Thank you for your inquiry regarding your mother's condition. Dizziness, particularly the sensation of lightheadedness or a feeling of heaviness, can indeed be a complex issue, especially when it is associated with vascular problems in the neck. Let's address your questions in detail.

1. Is vascular blockage really the main cause of dizziness? Is it possible for medication to clear it? Will it worsen over time?
Vascular blockage, particularly in the vertebral or carotid arteries, can significantly affect blood flow to the brain, leading to symptoms such as dizziness, lightheadedness, and even fainting. When these blood vessels are narrowed or blocked, the brain may not receive adequate blood supply, which can result in the symptoms your mother is experiencing.
While medications can help manage symptoms and improve blood flow, they often do not "clear" blockages in the same way that a surgical procedure might. Common medications include antiplatelet agents (like aspirin) and statins, which can help reduce the risk of further blockage and manage cholesterol levels. However, if the blockage is severe, more invasive treatments such as angioplasty or stenting may be necessary.

As for whether the condition will worsen, it is possible. Vascular health can deteriorate over time due to factors such as age, lifestyle, and underlying health conditions (like hypertension or diabetes). Regular monitoring and lifestyle modifications, including diet and exercise, are crucial in managing these risks.

2. Is it true that drinking more water can improve vascular blockage?
Staying hydrated is essential for overall health, including vascular health. Adequate hydration helps maintain blood viscosity and can support optimal circulation. However, while drinking water is beneficial, it is not a standalone treatment for vascular blockage. It is important to consider a holistic approach that includes a balanced diet, regular physical activity, and possibly medication as prescribed by a healthcare provider.

In summary, your mother's dizziness is likely related to the vascular blockage identified in her neck. While medications can help manage symptoms, they may not resolve the underlying issue. It is essential to maintain regular follow-ups with her healthcare providers to monitor her condition and adjust her treatment plan as necessary. Encouraging her to stay hydrated and adopt a healthy lifestyle can also contribute positively to her overall vascular health.

If her symptoms persist or worsen, it may be prudent to seek further evaluation, possibly including imaging studies or consultations with specialists in vascular medicine or neurology.
I hope this information provides clarity and helps you navigate your mother's health concerns. Please feel free to reach out with any further questions.

Best regards.
