Suggest Treatment For High Blood Pressure
Question: Yes, I have struggle with high blood pressure over the past month. During the day my blood pressure is slightly above normal (135/85) however at night I wake up a couple of hours after sleeping and my heart is racing and my blood pressure rises to 154/96 with a pulse rate of 90. My blood pressure during the day today was 140/76 with a pulse of 70 BPM and just before I went to bed my blood prressure was 118 / 80 with a pulse of 60. Why does my blood pressure go up when I sleep? I drank more than 16 ounces of water before I went to bed and I woke up thirsty and just drank 16 ounces water

Hello!
Welcome on HCM!
I passed carefully through your medical history and I could say that in general high blood pressure, when present peaks in the early morning hours (because of more increased levels of catecholamines and cortisol during the 24 hours circadian cycly.
These are substances, produced by our bodies, responsible for increasing blood pressure and pulse rate.
This is the general profile in the majority of normal individuals.
But, there are some reasons that this circadian profile of blood pressure may be shifted and several BP boats to appear more earlier or even in the evening:
-one of them may be an increased sympathetic nervous system stimulation, by increased production of intrinsic adrenaline, or by taking several stimulant drinks like taking caffeine, tea, energy drinks, cigarettes, etc.
-one major role in this regard plays anxiety. This may disrupt adrenaline production, leading to sleeping disorders, which may be manifested by impairment of sleep maintenance, sleep effectiveness and overall sleep quality.
Have you ever experienced any persistent stressful situation recently?
What about your sleeping quality? Do you feel tired and sleepiness during the day?
Are there any issues during your daily activity that trigger you an anxious mood?
What about smoking and caffeine intake?
I would like to let you know that you are a larger amount of water than usual. Having around 500ml water in the evening before sleeping, will certainly produce an increased blood volume in the subsequent hours, leading to increased blood pressure, increased renal filtration and consequently to secondary activation of some compensatory mechanisms, such as aldosterone and renine production, with the final conclusion of high blood pressure.
That's why you are experiencing high blood pressure profile.
I recommend you to discuss with your attending physician for performing a sleep quality estimation and a routine medical check up (general lab tests).
Let me know how is going on your blood pressure after reducing the evening water intake and sleep improvement.
Hope to have been of help!
If you have any other uncertainties, don't hesitate to answer.
Greetings!

Thanks Dr. Sharka for responding. I lowered my intake of water at night and my blood pressure when I wake up at 2 am and 5 am for the past two nights has been lower. Last night it was 123/84 with a heart rate of 63 at 2:25 am. However at 5:56 am it was 141/91 with a heart rate of 61. I took 5 more readings over the the next ten minutes and my final BP reading was 122/80 with a heart rate of 61. Today I exercised running vigorously for 10 minutes and then took my blood pressure. My initial blood pressure reading was 164/107 with a heart rate of 132. After two minutes it dropped to 128/97 with a heart rate of 110. I then took a final reading 15 minutes later and it was 128/88 with a pulse rate of 94. Is my diastolic pressure supposed to rise that high with exercise? When I exercised last night by just walking for 45 minutes my blood pressure reading after exercising was 114/82 with a heart rate of 64. I am concerned about the diastolic pressure rising so high during vigorous exercise. Should I avoid this type of exercise or is it safe to have my diastolic pressure rise this high? Thanks for your help.
Brief Answer:
There is nothing to worry about.
Detailed Answer:
Hello again!
Thank you for the additional information provided.
Your increased levels of both systolic and diastolic blood pressure during vigorous exercise,are just a normal reaction against a stressful physical or psychological situations. I would assure you that this denotes nothing dangerous and you don't need to worry about it.
The progressive decline of systolic and diastolic blood pressure within 30 minutes after stopping exercise, confirms this opinion.
As you have a moderate mitral regurgitation, I personally would not recommend you to undergo very excessively vigorous physical activity.
You should also avoid competitive sports. This, coupled with lowering of excessive anxiety, will also help in minimizing potential premature heart beats.
Hope to have been of help!
Wishing all the best!
