High blood pressure is a condition which doesn’t produce any immediate noticeable effects, meaning that those who have it are not always likely to realise that they do. It is, in fact, very common, and is thought to affect over one in four people in the UK. One of the main health risks associated with high blood pressure when left untreated is cardiovascular disease, such as stroke, heart attack, and angina.
During a blood pressure check, levels will be gauged with a device which uses a mercury-lined meter. The blood pressure figure is therefore given as reading of millimetres of mercury (mmHg). A reading contains two numbers, and these are measurements of systolic and diastolic pressure.
Systolic pressure defines the amount of force the heart needs to use when pumping blood out during a beat; whereas diastolic pressure is the space between beats, and provides an indication of the resistant pressure in the arteries. For example, a reading might be 120 (systolic) over 80 (diastolic). In cases where this reading is 140 over 90 or above, high blood pressure is said to be present.
There is no one single cause of the condition, but it is much more likely to occur in those who are older. Certain lifestyle factors can increase a person’s susceptibility to high blood pressure, including having a high salt intake, smoking, drinking too much alcohol, not doing enough physical exercise, and being overweight. In some instances, persons who have a family member with the condition may also be more prone to encountering it themselves.
One of the first courses of action a doctor may suggest is to address any potential contributing behaviours. They may, for instance, advise a patient to drink less alcohol, stop smoking, or change their diet and exercise regimen to help combat high blood pressure. But for some, these measures may not be enough to help lower levels, and treatment may be recommended.
Containing two functioning constituents, Prestim is a tablet which can help to relieve non-severe instances of high blood pressure. Timolol, which is a beta-blocker, works by inhibiting the action of certain hormones which can cause the heart to beat with more force. In doing this, it helps to reduce blood pressure.
The other ingredient is bendroflumethiazide, which is a type of drug called a diuretic. This works by increasing the rate at which the liver draws out salt from the blood, before transferring it into the urine. As this salt is extracted, it carries water alongside it. This lowers the presence of water in the blood, and also causes blood pressure to fall.
