Regarding blood pressure and medication?


Hello, Director He.
I have been on antihypertensive medication for over four years.
Initially, I attributed my high blood pressure to being overweight, but I have gradually lost weight, and in the last three months, I have lost about 10 kilograms.
However, my blood pressure remains unstable, especially the diastolic pressure.
I consulted my attending physician, who mentioned that my rapid weight loss combined with a high level of weekly exercise has caused my body to be in a more tense state.
Therefore, he advised me to rest for two weeks and switch to a diuretic (previously I was taking a calcium channel blocker).
I would like to ask you, Director He:
1.
Can rapid weight loss combined with intense exercise really lead to a more tense body and unstable blood pressure?
2.
Since switching to the diuretic, I haven't experienced any significant discomfort, but I do feel more fatigued and lacking in energy.
Why is that? (Could it be due to my anxiety?)
3.
After starting the diuretic, I sometimes feel a bit of warmth in my right flank.
Since my doctor advised me to avoid vigorous exercise, I walked for over three hours one day.
Could this discomfort be due to overexertion or high blood pressure? (Urination frequency, volume, and color are all normal.)
4.
Will the current instability in my blood pressure have a significant impact on my health? (Systolic pressure around 175, diastolic pressure 125.)
5.
Do beta-blockers used for hypertension affect sexual function?
I apologize for the many questions, but I hope to seek professional opinions beyond my attending physician.
Thank you very much!

Hello, I believe your persistent anxiety is causing your blood pressure to remain abnormal despite multiple measurements.
Moderate exercise is sufficient; the recommendation is 30 minutes a day.
Diuretics are not related to lower back pain, and excessive weight loss or intense exercise can be detrimental to your health.
Have you tried a beta-blocker? At your young age, the side effects should be minimal, but it may be more suitable for someone with sympathetic nervous system overactivity like yourself.
You might consider using bisoprolol.
Additionally, short-term blood pressure instability is not significantly harmful to your body, so there is no need to be overly anxious.
Changhua Hospital cares about you.

Managing blood pressure effectively is crucial for overall health, especially for individuals with a history of hypertension. Your situation, where you've experienced significant weight loss and increased physical activity, raises several important considerations regarding blood pressure management.

1. Rapid Weight Loss and Increased Exercise: Losing weight too quickly, especially combined with high levels of physical activity, can indeed lead to physiological stress on the body. When you lose weight rapidly, your body may not have enough time to adjust to the changes in metabolism and blood volume. This can lead to fluctuations in blood pressure, particularly if your body is in a state of stress or tension. The sympathetic nervous system may become more active, which can increase heart rate and blood pressure. Additionally, intense exercise can lead to dehydration, especially if fluid intake is not sufficient, which can also affect blood pressure regulation.

2. Effects of Diuretics: Switching to a diuretic can lead to feelings of fatigue or weakness, particularly if your body is adjusting to the medication. Diuretics work by increasing urine output, which can lead to a decrease in blood volume and, consequently, blood pressure. However, if you are not adequately hydrated or if your electrolyte levels become imbalanced, you may experience symptoms such as fatigue, weakness, or dizziness. It's essential to monitor your hydration and ensure you are consuming enough electrolytes, particularly potassium and magnesium, which can be depleted by diuretics.

3. Discomfort in the Right Side: The sensation of warmth or discomfort in your right side after prolonged walking could be due to muscle fatigue or strain, especially if you are not accustomed to such activity levels. It is also possible that the discomfort is related to blood pressure fluctuations, as high blood pressure can sometimes lead to sensations of pressure or discomfort in various parts of the body. However, since your urinary output and color are normal, it is less likely to be related to kidney function. If the discomfort persists, it would be wise to consult your healthcare provider.

4. Impact of Unstable Blood Pressure: Persistent high blood pressure, especially at levels like 175/125 mmHg, can have significant long-term effects on your health. It can increase the risk of cardiovascular events, such as heart attack or stroke, and can also affect other organs, including the kidneys and eyes. It is crucial to address these elevated readings promptly to prevent potential complications. Regular monitoring and adjustments to your treatment plan may be necessary.

5. Beta-Blockers and Sexual Function: Beta-blockers, a common class of medication used to manage hypertension, can indeed have side effects related to sexual function. These medications can lead to decreased libido, erectile dysfunction, or difficulties with orgasm in some individuals. If you are experiencing these side effects, it is important to discuss them with your healthcare provider, as they may consider adjusting your medication regimen or exploring alternative treatments.

In conclusion, managing blood pressure requires a comprehensive approach that includes monitoring your weight loss, adjusting your exercise regimen, and carefully managing your medication. It is essential to maintain open communication with your healthcare provider about your symptoms and any concerns you may have. They can help tailor a treatment plan that considers your lifestyle changes and ensures your blood pressure remains within a healthy range. Additionally, consider incorporating stress-reducing techniques, such as mindfulness or relaxation exercises, which can also positively impact blood pressure management.
