YOU Could Have Dangerous Blood Pressure And Feel Completely Normal.

Añadido: 2026-05-25

[00:00:00]If you've ever been told your blood pressure is a bit high, how do you know if it's actually dangerous or not?

[00:00:06]Because most people with high blood pressure feel completely fine and that's where the confusion starts.

[00:00:12]And I see this a lot. Someone's had a reading come back slightly raised and they're told, "Okay, let's just keep an eye on it." And they leave thinking, "Hmm, all right, no big deal."

[00:00:21]But that's not quite right.

[00:00:23]Blood pressure becomes a problem when it's consistently above a certain level.

[00:00:27]And it is the averages we're interested in, so not the kind of a one-off reading so much.

[00:00:31]And it's important not because of how it feels, but because of what's it doing in the background.

[00:00:38]So, your doctor may not yet have prescribed you any medication, but that doesn't mean you can ignore this.

[00:00:44]Maintaining a healthy blood pressure will reduce your risk of heart attacks and strokes. So, this is very important indeed.

[00:00:52]The numbers can be quite confusing, can't they? So, I'll try and make this simple. So, if your readings are consistently around 140 over 90 or higher, that is considered high.

[00:01:04]If they are 160 over 100 or higher, that is more concerning. And if it's very high, so around 180 over 120 or higher, especially if you have things like headache, chest pain, breathlessness, or any visual changes, that needs urgent assessment.

[00:01:21]And just to say, the exact cut-offs vary slightly depending on where you live in the world.

[00:01:27]Um, so I think the USA has different measurements. And um, also where you have done that reading.

[00:01:32]So, we expect people to have lower readings when they do their own measurements at home, but these are the ranges we use in practice in the NHS.

[00:01:39]And most people aren't in those extreme ranges, they're more in the middle.

[00:01:42]And this is where things get a bit misunderstood.

[00:01:45]Because it doesn't feel urgent, but it's also not harmless. So, high blood pressure is dangerous because of time, not just how high it is, but how long it's been there. And that's the part people underestimate. Because nothing happens immediately, but over years, that's going to increase your risk of heart attack and stroke, as well as things like kidney disease.

[00:02:08]So, what should you actually do?

[00:02:12]First, don't rely on a single reading.

[00:02:14]Look at the pattern over time.

[00:02:17]Second, if it is consistently high, don't ignore it just because you feel well.

[00:02:22]And third, focus on what actually makes a difference.

[00:02:27]All the things we talk a lot about all the time, maintaining a healthy weight, regular movement, reducing your alcohol and your salt, and prioritizing sleep.

[00:02:34]And sometimes, yes, you may need medication.

[00:02:37]I've got a video that goes through everything about this in more detail, so take a look if you think that might be helpful.

[00:02:44]And if you've never checked your blood pressure at home, that's a really useful place to start. And I've actually got another video, a little short one, showing you exactly how to get accurate readings.

[00:02:52]So, here's my take.

[00:02:54]High blood pressure is one of the clearest examples in medicine of something that feels completely fine, but isn't.

[00:03:01]And the danger isn't usually immediate.

[00:03:02]It's that slow build-up of risk over time. So, the goal isn't to panic about one number, but it is to take consistent elevation seriously. Because catching it early and acting on it is what changes where this ends up. That's how we play the long game. I'm Dr. Sophie, GP, here to help you understand your health and feel more in control.
