Managing blood pressure could help you live longer

-

or high blood pressure occurs when your heart is pumping blood too strongly through your body, putting extra strain on your blood vessels, heart and other organs, thereby increasing your risk of several potentiall­y life-threatenin­g health conditions.

Such conditions include heart disease, heart attack, stroke, peripheral arterial disease, aortic aneurisms, kidney disease and vascular dementia.

That is why managing your blood pressure and knowing what blood pressure measuremen­ts mean is important. Yet many people know little about high blood pressure or how to measure it. Many people who are hypertensi­ve are unaware of it.

To increase awareness of hypertensi­on, the World Hypertensi­on League, the umbrella organisati­on of 85 national hypertensi­on societies and leagues across the world, in 2006 launched World Hypertensi­on Day, which has been marked on May 17 every year since then.

Hypertensi­on is a major cause of premature death worldwide. According to the World Health Organisati­on, an estimated 1,28 billion adults aged between 30 and 79 have hypertensi­on. An estimated 46% of them are unaware that they have it.

Less than half of adults with hypertensi­on are diagnosed and treated. Only about one in five adults with hypertensi­on have it under control.

This year’s theme for World Hypertensi­on Day is ‘Measure Your Blood Pressure Accurately. Control It, Live Longer’. Its main aim is to increase awareness worldwide, especially in low to middle income areas, and to promote accurate blood pressure measuremen­t methods.

Causes

The exact cause of hypertensi­on is still unknown. However, several factors have been identified as likely causes. These include stress, smoking, being overweight or obese, lack of physical activity, excessive alcohol consumptio­n, too much salt in your diet, old age and genetics.

It is believed that one in every 20 cases of hypertensi­on is due to an underlying health condition or medication being taken.

Chronic kidney disease commonly results in high blood pressure. The kidneys help filter waste and extra fluids from the blood. When this does not happen, the excess fluid may lead to hypertensi­on. While stress is a commonly acknowledg­ed likely cause or contributi­ng factor, sometimes high blood pressure just happens when there is no obvious stress involved and none of the other likely causes are present.

Risk factors

A number of risk factors increase the chances of hypertensi­on. These include your age, size and weight, alcohol and tobacco use, and gender, with men more prone to hypertensi­on at a younger age than women.

Existing health conditions, such as cardiovasc­ular disease, diabetes, chronic kidney disease and high cholestero­l levels are all risk factors.

Other contributi­ng factors, include physical inactivity, a salt rich diet associated with processed and fatty foods, a low potassium diet, alcohol and tobacco use as well as certain diseases and medication­s.

A family history of high blood pressure and poorly managed stress may increase your risk of hypertensi­on.

Symptoms

Hypertensi­on is sometimes called the silent killer because there are generally no noticeable symptoms. While undetected, it can cause damage to your cardiovasc­ular system and internal organs, such as kidneys.

Checking your blood pressure regularly is, therefore, vital as there will usually be no symptoms to make you aware of the condition. Although there are generally no symptoms, high blood pressure may cause sweating, anxiety, sleeping problems and blushing. If it reaches the levels of a hypertensi­ve crisis a person may experience headaches and nosebleeds.

Long-term hypertensi­on can cause complicati­ons leading to the narrowing of blood vessels. This will make hypertensi­on worse as the heart must then pump harder to deliver blood to the body.

BP measuremen­t

Blood pressure is measured in millimetre­s of mercury. It is given as a pair of numbers, expressed as one number over the other. The upper number is systolic pressure, which is the pressure when your heart pumps blood out. The lower number measures the diastolic pressure, which is the presHYPERT­ENSION sure between heart beats.

Normal blood pressure is 120/80 or lower. It is considered elevated but not yet hypertensi­on if the top number is between 120 and 129 and the bottom number is below 80. Stage one hypertensi­on is when the top number ranges from 130 to 139 or the bottom number is between 80 and 89. Stage two hypertensi­on is when the top number is 140 or higher or the bottom is 90 or higher. Blood pressure higher than 180/120 is an emergency.

Treatment

Making some lifestyle is the first step managing your blood before it reaches the hypertensi­on.

Hypertensi­on is closely related to excess body weight. Weight reduction is normally followed by a fall in blood pressure. This can make a big difference to people with hypertensi­on, who are overweight. Regular physical exercise is recommende­d as it not only helps reduce weight but reduces high blood pressure. Simple forms of exercise include walking, jogging, cycling, swimming or dancing. You can also try highintens­ity interval training, which involves alternatin­g short bursts of intense activity with subsequent recovery periods of lighter activity.

Strength training can also help reduce blood pressure. Aim to include strength training exercises at least two days a week.

It is important to be consistent with your exercise routine as you risk the chances of your blood pressure shooting up again if you stop exercising.

Stress reduction is also important. Avoiding stressful situations may help. More important still is developing strategies to manage unavoidabl­e stress.

Alcohol, drugs and unhealthy eating add to hypertensi­ve problems. Smoking can raise high blood pressure. Giving up smoking reduces the risk of hypertensi­on, heart conditions and other health issues. A healthy balanced diet rich in whole grains, fruit and vegetables and low-fat dairy products can lower your blood pressure and reduce the risk of hypertensi­on-related complicati­ons.

If your blood pressure readings are consistent­ly higher than 130 over 80, you may require medication to control it. Possible medication includes diuretics, beta-blockers and alpha-blockers, calcium-channel blockers, central agonists, vasodilato­rs and peripheral adrenergic inhibitors. The choice of drug prescribed depends on your doctor’s assessment of what would benefit you most, given your general health and any other conditions you may have.
