Understanding Our Blood Pressure High blood pressure (Hypertension) is probably the most seen condition in society today. That said in many cases our lifestyle choices can have a profound effect on its levels and function. Our daily habits like consuming too much salt, smoking, alcohol consumption, drinking caffeinated beverages or carbonated drinks, lack of exercise, not controlling our body weight, to name a few add to the cause of the condition. Its effects can have a major impact on the workload of our cardio vascular system, as arteries have to work harder and their delicate membranes become damaged, bad cholesterol forms plaques and micro tears, the arteries become narrower and although they are usually stretchy, lose their elasticity and become stiff or narrow increasing Blood Pressure. What is Blood Pressure? Blood pressure is the pressure of blood in your arteries, the vessels that carry blood from your heart to your brain and the rest of your body. We need a certain amount of pressure to get the blood moving around our body. Our blood pressure naturally goes up and down throughout the day and night, and its normal for it to go up while moving about High Blood Pressure is when our overall blood pressure is consistently high even at rest and is usually established by an appointment with your GP. Low Blood Pressure (Hypotension) is when your blood pressure is below 90/60mmHg. This does not necessarily mean that there is a problem. How is Blood pressure measured? Blood pressure is measured in millimetres of mercury, mmHg, using a sphygmomanometer (pronounced svig-mo-man-ometer) This is usually a digital electronic monitor, which is connected to an inflatable cuff that is wrapped around your upper arm. When you have your blood pressure measured, the reading is written as two numbers. The first is when the pressure is at its highest, Systolic pressure and the second is at its lowest diastolic pressure. What are Systolic and Diastolic? • Systolic Pressure – This is the highest level of your blood pressure and happens when your heart beats and contracts to pump blood through your arteries. • Diastolic Pressure – This is the lowest level of your blood pressure and happens when your heart relaxes between beats. High Blood pressure is serious. If we ignore it, it can lead to heart and circulatory diseases like heart attack or stroke. If your systolic blood pressure is more than 129 mm/Hg or your diastolic blood pressure is higher than 79mm/Hg all of the time, you will have high blood pressure. This will increase the workload on your cardiovascular system and can lead to serious health problems. If the arteries that carry blood to your heart get damaged and clogged, it can lead to a heart attack. If this happens to the arteries that carry blood to your brain it can lead to a stroke. What is a healthy or normal blood pressure? Your blood pressure should be under 140/90 mmHg. Low • Systolic: lower than 90 mmHg • Diastolic: lower than 60 mmHg Normal • Systolic: lower than 140 mmHg • Diastolic: lower than 90 mmHg Possible hypertension • Systolic: between 140 and 180 mmHg • Diastolic: between 90 and 110 mmHg Severe hypertension • Systolic: higher than 180 mmHg • Diastolic: higher than 110 mmHg What causes high blood pressure? There isn’t always an explanation for the cause, in a small number of people, the cause can be identified but most people develop symptoms because of their diet, lifestyle or medical condition. Sometimes it runs in families and can also worsen with age, however you may still be able to improve it by changing your diet and being active. Doctors sometimes call this secondary hypertension. Causes of secondary hypertension include kidney disease, diabetes, and some medicines, such as oral contraceptives and some over the counter and herbal medicines If you are concerned that any medicine or remedy might affect your blood pressure, consult with your doctor. Symptoms of High blood pressure High blood pressure rarely has noticeable symptoms which is why it is so important to get your blood pressure checked. However, some people can experience blurred vision, nosebleeds, shortness of breath, chest pain, dizziness, and headaches. Over time it can lead to heart conditions, stroke, kidney disease… How to prevent and improve your High Blood Pressure Unfortunately, there is no magic cure for High Blood Pressure but changing your lifestyle can significantly lower the risk. Working with your GP is important not only to establish your blood pressure levels and monitor but also, they may prescribe medicine to help control. But without doubt making healthy lifestyle changes can help. For example, losing weight and exercising for 30 minutes a day, (always seek medical advice before starting any exercise or weight loss plan), eating a healthy balanced diet to include a high potassium content and low salt intake which will reduce the tension in the blood vessels, fish containing omega-3 fatty acids twice a week, as omega-3 has been proven to reduce blood pressure, foods with magnesium and fibre to reduce the risk of heart disease, and reduce alcohol, smoking and processed foods.
