Dizziness and blood pressure?


Hello, at the end of November, I experienced a spike in blood pressure up to 200 while in Germany and went to the emergency room.
I was prescribed two medications: Metoprolol and Diltiazem 80 mg.
After taking them for three days, I returned to Taiwan and immediately visited a cardiology clinic on December 1 for some tests, including blood tests, an electrocardiogram, echocardiogram, chest X-ray, and abdominal ultrasound, all of which were normal.
However, I have been feeling a persistent pressure in my head, difficulty walking quickly, and my blood pressure readings in the morning and evening have gradually decreased to 113-130/69-75.
During my follow-up appointment on December 22, the doctor assessed that I could temporarily stop taking Metoprolol and continue with Diltiazem 80 mg (taken at 6:30 AM).
I was advised to return for a follow-up in two weeks.
During this period, my blood pressure remained stable at 110-130/70-80.
On December 27, around 10:00 AM, I started feeling pressure in my head and slight dizziness, with occasional numbness on the left side of my face and the back of my head.
When I felt uncomfortable, my blood pressure did not exceed 130/80.
This discomfort lasted for two days, starting in the morning and improving only by the evening.
I would like to know if this could be due to significant side effects from the medication, whether I should stop the medication, or if I need to consult a neurologist.
Thank you.

Hello, not all discomfort is caused by blood pressure, but discomfort can lead to fluctuations in blood pressure, causing symptoms like head heaviness and dizziness, as well as numbness in the face and back of the head.
It would be advisable to consult a neurologist.
For now, there is no need to adjust your blood pressure medication; let's observe the situation.

More Info


Understanding dizziness and fluctuations in blood pressure can be quite complex, especially after experiencing a significant spike in blood pressure, as you did in Germany. Your situation involves several factors that need to be considered, including medication effects, underlying health conditions, and the psychological impact of your experiences.

Firstly, it's important to recognize that high blood pressure (hypertension) can lead to various symptoms, including dizziness, headaches, and feelings of pressure in the head. The medications you were prescribed, such as Metoprolol (脈優) and Amlodipine (得安穩), are commonly used to manage hypertension. Metoprolol is a beta-blocker that can lower heart rate and blood pressure, while Amlodipine is a calcium channel blocker that helps relax blood vessels. Both medications can have side effects, including dizziness, fatigue, and sometimes a feeling of heaviness in the head, especially when starting treatment or adjusting dosages.

Given that your blood pressure readings have stabilized between 110-130/70-80 mmHg, this is generally considered a normal range. However, the recurring feelings of dizziness and the sensation of pressure in your head, along with facial numbness, are concerning. These symptoms could be related to several factors:
1. Medication Side Effects: It is possible that the medications, particularly if you have recently adjusted the dosage or frequency, could be causing these symptoms. Beta-blockers can sometimes lead to fatigue and dizziness, especially if your body is still adjusting to the medication.

2. Orthostatic Hypotension: This is a condition where blood pressure drops significantly when standing up, which can lead to dizziness. If you are experiencing dizziness upon standing or changing positions, this could be a factor.

3. Anxiety or Stress: The experience of having high blood pressure and the subsequent medical evaluations can lead to anxiety, which can manifest as physical symptoms, including dizziness and a feeling of pressure in the head.

4. Neurological Concerns: The occasional numbness in your face and head could warrant further investigation, particularly if it persists. While it may not be directly related to your blood pressure or medications, it is essential to rule out any neurological issues.

Given these considerations, here are some recommendations:
- Consult Your Doctor: It is crucial to discuss your symptoms with your healthcare provider. They may want to evaluate your medication regimen, considering the side effects you are experiencing. They might suggest a gradual tapering of the medication or switching to a different class of antihypertensive if necessary.

- Monitor Symptoms: Keep a detailed log of your symptoms, including when they occur, their duration, and any activities that seem to trigger them. This information can be invaluable for your doctor in determining the underlying cause.

- Consider a Neurological Evaluation: If the facial numbness and dizziness persist, it may be wise to consult a neurologist to rule out any neurological conditions.

- Lifestyle Modifications: Continue to maintain a healthy lifestyle, including a balanced diet, regular exercise, and stress management techniques. These can help manage blood pressure and overall well-being.

- Follow-Up Appointments: Ensure you keep your follow-up appointments with your cardiologist to monitor your blood pressure and overall heart health.

In conclusion, while your blood pressure appears to be under control, the symptoms you are experiencing warrant further investigation. It is essential to communicate openly with your healthcare provider about your concerns and work together to find the best approach to manage your health.
