Blood pressure issues


Hello, doctor.
At the end of January, I had a blood pressure reading of 160/110 at the clinic, so the doctor prescribed the antihypertensive medication Amlodipine 5/40, which I took once daily for five days.
After discussing with the doctor, I decided to stop the medication to confirm whether I truly have hypertension.
I stopped taking the medication on January 30, and it has been over a month since then.
I have been measuring my blood pressure every morning and evening, and most of the time, my systolic pressure is between 110 and just over 120, while my diastolic pressure is around 65 to 75.
However, two weeks after stopping the medication, there were a few days when I occasionally measured above 130/80, but the rest of the time it was normal.
Recently, in the past two weeks, I have noticed that my blood pressure has been noticeably higher, with systolic readings of at least 125, approaching or exceeding 130, and diastolic readings between 75 and 85.
During these two weeks, there were also a few days when my daytime readings exceeded 130/80, with some approaching 140/90.

1.
Is my current condition caused by stopping the medication?
2.
Does this qualify as hypertension?

1.
It is possible.
2.
In May 2022, the Taiwan Society of Cardiology and the Taiwan Hypertension Society published guidelines that officially adjusted the definition of hypertension from 140/90 mmHg to 130/80 mmHg.
It is recommended to measure blood pressure using "home blood pressure" as the standard.
If it exceeds this threshold, it is advised to seek medical attention and discuss treatment options with your physician!

When it comes to managing blood pressure, particularly after stopping medication, it is essential to understand the complexities involved in blood pressure regulation and the potential implications of discontinuing antihypertensive therapy. Based on your situation, let's delve into your questions regarding blood pressure fluctuations after stopping medication.

1. Is your current situation a result of stopping the medication?
It is possible that your fluctuations in blood pressure could be related to the cessation of your antihypertensive medication, especially if you were initially diagnosed with high blood pressure. When you stop taking blood pressure medications, your body may react in various ways. Some individuals experience a rebound effect, where blood pressure rises after discontinuation. However, it is also crucial to consider other factors that can influence blood pressure, such as stress, diet, physical activity, and overall lifestyle changes. Since you have been monitoring your blood pressure regularly and have observed readings that fluctuate between normal and slightly elevated, it suggests that your body is adjusting to the absence of medication.
2. Does this count as high blood pressure?
According to the American Heart Association, normal blood pressure is defined as less than 120/80 mmHg. Elevated blood pressure is categorized as systolic readings between 120-129 mmHg and diastolic readings less than 80 mmHg. Hypertension is diagnosed when blood pressure readings are consistently at or above 130/80 mmHg. Given your recent readings, where systolic pressure has approached or exceeded 130 mmHg, it may indicate that you are entering the hypertensive range, particularly if these readings are consistent over time.
It is important to note that a single elevated reading does not necessarily mean you have hypertension; rather, it is the pattern of readings over time that is significant. If your blood pressure readings remain elevated, it would be prudent to consult with your healthcare provider for a comprehensive evaluation. They may recommend a 24-hour ambulatory blood pressure monitoring to assess your blood pressure throughout the day and night, which can provide a clearer picture of your blood pressure status.


Additional Considerations:
- Gradual Medication Discontinuation: If you were on antihypertensive medication, it is generally advisable to taper off rather than stop abruptly, especially with certain classes of medications like beta-blockers. This can help minimize withdrawal symptoms and potential rebound hypertension.


- Lifestyle Modifications: Regardless of medication status, lifestyle plays a crucial role in managing blood pressure. Maintaining a balanced diet low in sodium, engaging in regular physical activity, managing stress, and avoiding tobacco and excessive alcohol can significantly impact blood pressure control.

- Regular Monitoring: Continue to monitor your blood pressure regularly. Keeping a log of your readings can help you and your healthcare provider make informed decisions about your treatment plan.

- Consultation with a Healthcare Provider: Given your fluctuating readings and the potential for developing hypertension, it is advisable to have a follow-up appointment with your healthcare provider. They can assess your overall health, consider your medical history, and determine whether medication is necessary or if lifestyle changes alone can suffice.

In conclusion, while your blood pressure fluctuations may be influenced by stopping your medication, it is essential to evaluate the broader context of your health and lifestyle. Regular monitoring and consultation with your healthcare provider will be key in managing your blood pressure effectively.
