Whenever you gain weight your heart has to push harder, thus increasing pressure inside blood vessels, which leads to increased blood pressure in some of us. As we gain weight your angiotensin level can which increase which helps to regulate the pumping pressure inside the heart. Some people are more susceptible to angiotensin than others.
Also, lets not forget about lipid levels when we are taking hormones. These ratios are not good for an optimal b/p. **** long term equates to damage at these ratios.
Just b/c you stop hormones does not mean your b/p is going to normalize at all. It should if you are young enough. The more we use and the older we get, the longer it takes for our feedback loops to normalize.
Plus hormones can lead to hypercalcemia which is the conduction mechanism for your SA Node to begin the pumping action. This can also lead to higher blood pressure. I feel as long as the ranges are kept to a normal limit everything should be okay. If they aren't (as in my case b/p use to be 160/80) we start taking medications. I have been on shitloads of different types of b/p medications. If any of you have to go on them do yourself a favor and start with hydrochlorthiazide. It is a diuretic. Get the benefit of losing water weight, kidneys function better, cheap, studies have shown they work as well as the rest of them. Downside is can get low pottasium levels which can lead to death. But ****, before you die your muscles are going to be twitching like a son of a bitch. It is easy to get 2g of K a day.
It could take awhile for your Ca levels to normalize. In addition, serum chloride, potassuim, phosphate, and sodium levels may be increased which can lead to higher b/p for a number of reasons. This is where some of the water retention comes from. Another way our feedback loops get screwed up. Think of all the things these elements control in our body. Like everything. They are fundamental cellular elements necessary for our body to function correctly.
As we can see there are so many reasons why blood pressure increases it's hard to say if, when, why, and how. I am sure there are even other reasons I have not covered. In essence, time, age, luck, diet, strength of signaling mechanisms control high b/p. If your parents have it you will most likely. They are finding heridary genes associated with some people having high b/p.
