“weight is weight”; this is crap. This doctor is an idiot.
When you get fat your body creates millions of tinny arterioles to feed and maintain the fat tissue. This is extremely difficult for blood to flow through because they are so small and if you are really fat, you have a lot of them.
So it is like your heart trying to suck a grape seed through a straw. This causes a backup of blood in you arterial system and left side of your heart. In turn causing high blood pressure.
On the other had, increased muscle is not the same. Muscle tissue is VERY vascular and blood flows in and out of it very well. The only issue would be making sure your heart can supply the blood when needed as the muscle become bigger and need more 02 and blood supply during exercise.
This is why you need to do some cardio work to help you heart “catch up” to your muscles. Your heart does get stronger by weight training, but IMO, anaerobic training does not develop it to the extent that cardio (aerobic) training does.
So weight is not weight.
Lastly, some people have hypertension from renal issues or other factors. These are the people who need to be careful about sodium and other lifestyle factors including medications. But for someone who does not fit into this sodium sensitive category, sodium is a non-issue.
Your edit is incorrect.
How so? The left side of the heart feeds out to the arterial system. If the arteries become constricted (through faulty activation of the RAA system, or chronic stress, etc) then this causes an increase in BP.
Eventually, after much time and attempts by the heart to compensate, the blood backs up in the left ventricle which is unable to contract forcefully enough to eject all the blood. This causes a back up in the pulmonary system and eventually the right side of the heart.
The venous system does not become conjected before the arterial system in nearly all cases of hypertension from what I understand.
So you said:
“So it is like your heart trying to suck a grape seed through a straw. This causes a backup of blood in you venous system and left side of your heart.”
However the heart does not “suck up” anything, since that would imply negative pressure through the venous system into the vena cava. The heart is fed through slight positive pressure, it does not ‘suck’. Your analogy is faulty.
Besdies, the venous system feeds the right side of the heart not the left.
However if I have missed your point, then I’m sorry. Please explain to me what you meant.[/quote]
Wow, very knowledgable. That was a great read! Thanks for the info. I understand Lorisco analogy at the same time though. His info wasn’t totally correct but he made a great point I think.
