So we seem to have created a theme… with blogs on
hypoglycemia and
hypothermia over the last few weeks. But today, we turn to hyper… hypertension.
Hypertension is simply the medical term for high blood pressure and as a condition it rarely has noticeable symptoms. But if it’s left untreated, it increases your risk of serious problems such as heart attacks and strokes. Hence, it’s sometimes referred to as the silent killer! Which is very dramatic, but also important to know.
Around a third of adults in the UK have high blood pressure, although many won’t realise, as the the only way to find out if your blood pressure is high is to have your blood pressure checked.
If you do have symptoms of hypertension, then you might notice headaches, dizziness, fainting episodes, nosebleeds, blurred vision, chest pain and being short of breath.
Blood pressure is measured in ‘millimetres of mercury’ (mmHg) and recorded with two numbers. The systolic pressure (higher number) is the force at which your heart pumps blood around the body. The diastolic pressure (lower number) measures the resistance to the blood flow in the blood vessels.
Everyone's blood pressure will be slightly different and will vary throughout the day and night. What's considered low or high for you may be normal for someone else. But as a general guide:
- The ideal blood pressure is around 120/80.
- A high blood pressure reading is considered to be 140/90 or higher (or 150/90mmHg or higher if you're over the age of 80).
- A low blood pressure is considered to be 90/60 or lower.
Blood pressure readings between 120/80 and 140/90 could mean you're at risk of developing high blood pressure if you don’t take steps to keep it under control.
If your blood pressure is too high, it puts extra strain on your blood vessels, heart and other organs, such as the brain, kidneys and eyes. Persistent high blood pressure can increase your risk of a number of serious and potentially life-threatening health conditions, such as:
- Heart disease
- Heart attacks
- Strokes
- Heart failure
- Peripheral arterial disease
- Aortic aneurysms
- Kidney disease
- Vascular dementia
Of course for many of our clients, these conditions are career-threatening as well as dangerous to health if blood pressure remains high after treatment. But the good news is that if you have high blood pressure, reducing it even a small amount can help lower your risk of these conditions.
It's not always clear what causes high blood pressure, but there are things that can increase your risk such as:
- Being overweight
- Eating too much salt and do not eat enough fruit and vegetables
- Not doing enough exercise
- Drinking too much alcohol or coffee (or other caffeine-based drinks)
- Smoking
- Not getting enough sleep or having disturbed sleep
- If you are over 65
- If a relative has high blood pressure
- If you are of black African or black Caribbean descent
- Living in a deprived area
- Stress
Making healthy lifestyle changes to counteract these risks can sometimes help reduce your chances of getting high blood pressure and help lower your blood pressure if it's already high. Cutting back on alcohol and caffeine, stopping smoking, getting more exercise, eating less salt and losing weight will all help to reduce your blood pressure.
Doctors can also prescribe a range of medications to help manage blood pressure, generally in conjunction with some recommended lifestyle changes.
So the good news is, there’s a lot you can do to help to manage and maintain your blood pressure in safe ranges. But it’s worth keeping an eye on it, as blood pressure is one of the checks required for your ENG1. You can also find out more using this link to the
