The simplest and easiest thing one can do, apart from diets and exercise, is to permanently and considerably lower their daily salt intake.
Decreasing your salt intake leads to maybe a 1 to 3% lowering of your bp. Decreasing your salt intake can increase your mortality risk. Better advice regarding salt is to consume as much as your body wants. The problem really is the foods that accompany salt intake...eg. chips and snacky crap. The long term solution to high bp is to lower your body fat percentage ....this is done by diet in the main and exercise preferably strength training.
How do you deal with your low blood pressure? I have something similar and it seems to have developed around the age of 44-45. I feel it when I've been sitting for a little and get up to walk around. Feels like a pressure in my head. Did some checking and noticed that it's postural hypotension.
If you were diagnosed with hypotension by a Doctor...he/she should have prescribed you medicine that would help you retain more water or gave advice you to regularly drink more water along with referring you to a nutritionist that deals with low blood pressure issues. If you self-diagnosed...still immediately see your Doctor for verification because you don't want to have a serious health problem (ticking bomb) that's causing the low blood pressure. In contrast, I developed it while in a coma last fall. They put medicine in my IV to help stabilize my blood pressure. Now I regulate it via drinking more water especially after exercise without medication although I still do get blood transfusions. Yet, the doctors did tell me if I couldn't regulate it after seeing a nutritionist about the low blood pressure along with the increased water intake... She would prescribe medicine to help me retain water and potassium. Its important to remember that now you're over the age of 44...low blood pressure like high blood pressure...can lead to strokes, heart attacks and problems with your kidneys. You should purchase a blood pressure machine (a good one usually cost aroud $100) and take your pressure several times per day. Monitor how your water intake and adjusted eating habits with the help of a nutritionist to determine if the problem is your eating habits. For me, I too "had" hypotension and "had" hypokalemia when I came out of the coma. All of that combined with not moving my muscles for almost 2 months...I couldn't even lift my arms to wipe my own nose. I was just extremely weak. Doctors keep telling me it'll take about a year to return back to the way I was prior to my illness. I've put on about 30% of the weight I've lost, back to exercising and I have less fainting (I have a medical restriction because of this...not allowed to drive until November and only with the approval by my doctor). I'm hoping by next spring I can get back to cycling (sprint racing), handball (competition) and boxing (for fun). The coma from pneumonia last year...I went into shock (blood pressure plunged), had to be revived two times, put on a breathing machine for almost the entire duration in the coma and then there's the after effects like having hypotension, hypokalemia and extreme anemia. I see the doctors (a team of 5) several times every month...lots of blood tests until November. My point, you want to find out the cause of your low blood pressure. For me, it was easy for the doctors to determine my cause while I was still in the hospital. Now I'm back to trading...just now feeling like I have a grip of it again...that critical mental aspect that's a big part of trading.
