Dr. Sanjay Gupta

There's stuff going on in your body and that damage is happening, happening, happening.

And then it starts showing up 10, 15, 20 years later.

So one would argue that certainly in the UK, one in four people have hypertension.

One in four?

Yeah.

Globally, it's about 30%.

Wow.

They have hypertension, meaning their numbers are higher than what the guidelines recommend.

In terms of numbers, I think also it's important to understand that your number may be within normal range, but may still be high for you and may still be...

harming you and therefore that is why it's so useful to look for evidence of harm because you understand that person if we're just going on the superficial side and saying oh what number will keep me happy i'd say if it's below 140 over 90 then that's what the guidelines say is acceptable right

We're in the business of treating populations.

And when you're trying to treat populations, resources tend to be a little bit more limited.

You want to do the easiest thing, et cetera, et cetera.

And that's why things are happening.

But I think there is a better way of doing it.

So if I have a patient, I would say, well, look, first, let me work out what your number is.

Let's work with one number, not it's 120 over 80 now.

It was 130 over 80 10 minutes ago.

Yesterday was 125.

What is your number?
