I know coming from a doctor, it might sound crazy, but the problem is, as you rightly pointed out, it's a silent killer.
So you could be walking around with an elevated blood pressure with no symptoms.
Some patients do experience headaches, nose bleeds, they could have difficulty breathing or could have symptoms which the secondary causes are causing them.
But per se, hypertension itself might not have many symptoms till it has impacted your organs and those symptoms then bring the hypertension into the picture.
- So let's say you may be having symptoms like a heart attack symptom and, you know, the high blood pressure which could lead to heart disease, could lead to the heart attack.
So it's kind of a, you gotta be on the lookout for a lot of different things, right?
- Sure, so I'm an interventional cardiologist, so I'm on the front lines when patients come in with heart attack, and I can tell you it's not an uncommon thing that someone figures out or finds out that they have a elevated blood pressure the first when they have a heart attack.
