You probably have high blood pressure (hypertension) if
your blood pressure readings are consistently 140 over 90, or higher, over a
number of weeks. You may also have high blood pressure if just one of the
numbers is higher than it should be over a number of weeks. If you have high
blood pressure, this higher pressure puts extra strain on your heart and blood
vessels. Over time, this extra strain increases your risk of a heart attack or stroke.
High blood pressure can also cause heart and kidney disease, and is closely
linked to some forms of dementia. You can check your blood pressure on our Blood
Pressure Chart.
Signs and symptoms of high blood pressure
High blood pressure usually has no signs or symptoms, so
the only way to know if you have high blood pressure is to have yours measured.
However, a single high reading does not necessarily mean you have high blood
pressure. Many things can affect your blood pressure through the day, so your
doctor will take a number of blood pressure readings to see that it stays high
over time. Occasionally people with very high blood pressure say they
experience headaches, but it is best to visit your GP if you are concerned
about symptoms.
Causes of high blood pressure
For most people, there may be no single cause for their
high blood pressure. We do not know exactly what causes high blood pressure. We
do know that your lifestyle can affect your risk of developing it. You are at a
higher risk if, you eat too much salt, you don’t eat enough fruit and
vegetables, you are not active enough, you are overweight or you drink too much
alcohol. You can help to lower your blood pressure and your risk of stroke and
heart attack by making life style changes.
Additional causes of high blood pressure
There are some factors that increase your risk of
developing high blood pressure, which you cannot control. These include age, as
you get older, the
effects of an unhealthy lifestyle can build up and your
blood pressure can increase, Ethnic origin: people from African-Caribbean and
South Asian communities are at greater risk than other people of high blood
pressure. Family history: you are at greater risk if other members of your
family have, or have had, high blood pressure. Some people may have high blood
pressure that is linked to another medical condition, such as kidney problems.
For these people treating the medical problem may lower their blood pressure
back to normal.Control high blood pressure without medication
