If you know the causes of high blood pressure, you know what to avoid - right?
The causes of high blood pressure
I said earlier that we don’t know the causes of high blood pressure. Talking about blood pressure is like body weight - there is no easy explanation as to why some people have more problems staying in the normal range compared others with a similar lifestyle - people differ in some fundamental way.
For example, we can say definitely, in the case of weight, that too much food and a lack of exercise will make you fatter.
Similarly we know some of the things that can make blood pressure high. We just don't know what root cause upsets the body's control mechanisms. Also there are still many mysteries as to why people differ so much in their body's response to some things that raise blood pressure.
The way the body controls blood pressure is a complex business, balancing many factors. The body has to have the means to react fast to situations, like exercise or standing up, to keep enough blood flowing to where it is needed. Different mechanisms control it over longer periods of time.
Anything that causes high blood pressure does so by affecting one or more of the many control factors that are in balance and we can safely say what a lot of those things are. Since the story is not the same for everyone, the solutions are also likely to vary.
The main culprits
