Treating High Blood pressure in older people
Know your blood pressure
High blood pressure is just one of the risk factors for older people in developing heart disease, along with high cholesterol, diabetes and other lifestyle factors
As many as 5 million people in the UK are walking around, undiagnosed, with high blood pressure<
The only way to know whether you have high blood pressure is to have it measured
Everyone should know their blood pressure
The British Heart Foundation recommend that everyone over 40 gets their blood pressure taken by a nurse or doctor as part of a regular health check to assess their risk for getting heart and circulatory disease
What is blood pressure?
Put simply, blood pressure is the pressure of blood in your arteries – the tubes that carry your blood from your heart to your brain and the rest of your body
You need a certain amount of pressure to get the blood round your body
The pressure of the blood flowing through your arteries changes when your heart is pumping and when it is at rest
The pressure in your arteries will be at its highest when your heart is pumping and lowest as it relaxes before it pumps again
Every blood pressure reading consists of two numbers or levels:
- They are shown as one number on top of the other and measured in mmHg, which means millimetres of mercury
- If your reading is 120/80mmHg, you might hear your doctor or nurse saying your blood pressure is “120 over 80”
- The first (or top) number represents the highest level your blood pressure reaches when your heart beats and pumps blood through your arteries – your systolic blood pressure. An example might be 130mmHg
- The second (or bottom) number represents the lowest level your blood pressure reaches as your heart relaxes between beats – your diastolic blood pressure. An example might be 75mmHg
You should have your blood pressure measured so that you know what your target is. Unless your doctor tells you otherwise, your blood pressure should be below 140/85mmHg
If you have heart or circulatory disease, including being told you have coronary heart disease, angina, heart attack or stroke, or have diabetes or kidney disease, then it is usually recommended that your blood pressure should be below 130/80mmHg
What is high blood pressure?
High blood pressure – or hypertension – means that your blood pressure is constantly higher than the recommended level
High blood pressure is not usually something that you can feel or notice, but over time if it is not treated, your heart may become enlarged, making your heart beat less effectively, which could lead to heart failure
Having high blood pressure increases your chance of having a heart attack, or stroke
There isn’t always an explanation for the cause of high blood pressure, but these can play a part:
- not doing enough physical activity
- being overweight or obese
- having too much salt in your diet
- regularly drinking too much alcohol
- not eating enough fruit and vegetables or,
- having a family history of high blood pressure.
Even if you don’t have high blood pressure, making simple lifestyle changes may help prevent you having it in the future
What can I do to reduce my blood pressure?
If your doctor or nurse says you have high blood pressure, he/she is likely to encourage you to make some lifestyle changes to help reduce it
This may include increasing your physical activity, losing weight, reducing the salt in your diet, cutting down on alcohol and eating a balanced, healthy diet
If your blood pressure is very high, or these lifestyle changes do not reduce it enough, your doctor is likely to prescribe you medication to control it and to reduce your risk of having a heart attack or stroke
