Blood pressure issues?


Hello Doctor, I started experiencing dizziness around the Lunar New Year when I returned to work, but I did not have dizziness during my time off.
Starting from February 27, the dizziness suddenly worsened, and I felt dizzy all day long.
I even began to experience a heavy and tight headache at the top and back of my head, along with significant tightness in my shoulders and neck.
I went to the hospital to see a doctor, who asked me to measure my blood pressure.
Initially, it was 143, but since I was holding my urine at the time, after resting, it measured 132/92.
The doctor prescribed Acetaminophen, Metoprolol (which the doctor told me is for palpitations, but I noticed on the medication label that it also seems to lower blood pressure), and instructed me to measure my blood pressure morning and evening for seven days to show the doctor later.
After returning home, I measured my blood pressure once on each arm after waking up and before going to bed.
Regardless of whether it was before or after taking the medication, my blood pressure ranged between 101-120/70-80.
Could this decrease in blood pressure be due to the medication? Does my situation indicate that I have hypertension? Thank you.

More Info


Understanding blood pressure issues, particularly in the context of dizziness and medication, is crucial for effective management and diagnosis. Based on your symptoms and the medical history you've provided, it seems that you are experiencing a combination of dizziness, tension headaches, and elevated blood pressure readings at certain times. Let's break down the various aspects of your situation.


Blood Pressure Readings
Your initial blood pressure reading of 143 mmHg systolic is considered elevated, especially since it was taken under conditions that may have influenced the result (e.g., holding urine). After resting, your reading of 132/92 mmHg indicates that while your systolic pressure is still on the higher side, your diastolic pressure is also elevated, categorizing it as stage 1 hypertension according to the American Heart Association guidelines.

Symptoms of Dizziness and Headaches
Dizziness can be caused by a variety of factors, including blood pressure fluctuations, dehydration, anxiety, or even medication side effects. The tightness and heaviness in your head, along with shoulder and neck tension, may suggest muscle tension headaches, which can be exacerbated by stress or poor posture.

Medication Effects
The medications prescribed to you—acetaminophen for pain relief and propranolol, which is often used for managing anxiety and palpitations—can indeed have an impact on your blood pressure. Propranolol is a beta-blocker that can lower heart rate and blood pressure, which may explain the lower readings you observed at home. It’s important to note that while propranolol can help manage symptoms of anxiety and palpitations, it is not primarily a medication for hypertension unless prescribed for that purpose.


Monitoring Blood Pressure
Your home blood pressure readings of 101-120/70-80 mmHg are within the normal range, suggesting that your blood pressure may be well-controlled, particularly when you are at rest. This could indicate that the medication is effective in managing your blood pressure, or it may reflect a natural variation in your blood pressure throughout the day.

Diagnosis and Next Steps
Given your symptoms and the variations in your blood pressure readings, it is essential to follow up with your healthcare provider. They may want to investigate further to rule out any underlying conditions that could be contributing to your symptoms, such as anxiety disorders, thyroid issues, or other cardiovascular concerns.

Conclusion
In summary, while your initial readings indicated elevated blood pressure, your subsequent readings suggest that you may not have persistent hypertension, especially if your symptoms improve with medication. It is crucial to continue monitoring your blood pressure as advised and to maintain open communication with your healthcare provider about your symptoms and any changes you experience. If dizziness persists or worsens, or if you experience additional symptoms such as chest pain or shortness of breath, seek medical attention promptly.
Always remember that managing blood pressure is a multifaceted approach that includes lifestyle modifications, medication adherence, and regular monitoring. Your healthcare provider can help tailor a plan that best suits your needs and health status.
