High blood pressure – also known as hypertension – could lead to serious problems if left untreated.
If your blood pressure is too high, it puts extra strain on your blood vessels and vital organs.
It can increase your risk of life-threatening conditions, including heart attacks, strokes and vascular dementia.
High blood pressure rarely has any symptoms, but there are some tell-tale signs that you could be at risk of hypertension, and should get it checked.
“One of the most dangerous aspects of hypertension is that you may not know that you have it,” said WebMD.
“In fact, nearly one-third of people who have high blood pressure don’t know it.
“The only way to know if your blood pressure is high is through regular checkups.
“If your blood pressure is extremely high, there may be certain symptoms to look out for.”
Severe headaches, fatigue or confusion could be signs of high blood pressure, the medical website said.
Other symptoms of hypertension include vision problems, chest pain and difficulty breathing.
Finding blood in your urine, having an irregular heartbeat, or having pounding in your chest, neck or ears could also be signs of the condition.
If you have any of these symptoms, you should see a GP immediately, WebMD advised.
The only way to find out if you have high blood pressure is to get checked, according to the NHS.
The ideal blood pressure is somewhere between 90/60mmHg, and 120/80mmHg.
Anything above 140/90mmHg is considered high blood pressure.
You can lower your blood pressure by cutting back on the amount of salt you eat. Regularly exercising, losing weight – if you’re overweight – and cutting down on caffeine could also help to reduce blood pressure.
