Hypertension: What You Need to Know


If you have high blood pressure, you may not even know about it. That's why high blood pressure is often called the ‘silent killer’. There are rarely any signs or symptoms and millions of people with hypertension don’t even know they have it.” Kepha Nyanumba - Consultant Nutritionist
You can’t see high blood pressure, also called hypertension. And most of the time, you can’t feel it. But if you’re among the 1.13 billion people who have hypertension, it’s important to understand its effects on your health and take action to bring your numbers down to healthier levels. Blood pressure is a measure of the force that your blood applies to the walls of your arteries as it flows through them. When arteries are well dilated and in good health, blood flows with ease hence the heart is not overworked. However, if the arteries are stiff or too narrow, blood pressure increases and the heart becomes overburdened. It's normal for your blood pressure to temporarily increase when you exert yourself, or when you feel anxious or stressed. But if your blood pressure is consistently higher than the healthy level when at rest, it is called hypertension.
Blood pressure is an essential part of the way your body works. Your blood carries oxygen and nutrients around your body and is pumped by your heart. Your blood is under pressure as a result of the pumping action of your heart and the size and flexibility of your arteries, which carry your blood. According to the World Health Organization, high blood pressure affects more than one in three adults worldwide. If you have very high blood pressure, or your blood pressure rises quickly, you may have headaches, problems with your vision etc. Making lifestyle adjustments brings blood pressure down and in other cases, you may need a combination of lifestyle changes and medication to control your blood pressure.
