High Blood Pressure Symptoms

Unfortunately, there are often no symptoms of high blood pressure – which is why it is often called the “silent killer”.

You will often find out you suffer from high blood pressure (hypertension) on a routine visit to the doctor, or when going to see the doctor about another complaint (which may be as a direct result of your high blood pressure).

It is possible that you might suffer from headaches, nausea, dizziness or blurred vision, but many people will not even experience these symptoms.

High blood pressure puts your cardiovascular system under enormous strain, which can result in serious health problems, even death. High blood pressure is often responsible for heart attacks, strokes, and aneurysms.

When you suffer from high blood pressure, the capilliaries in your body can be easily damaged because of the pressure, meaning organs such as the eye and kidneys can be easily damaged.

How to tell if you have high blood pressure

There is only one way to be certain. Get it measured.

You can go to your doctor, or get a home blood pressure monitor and measure it yourself. Because of a syndrome called White Coat Syndrome, I personally prefer to measure mine myself.

There are various drugs and medications for high blood pressure treatment, though these can often have undesirable side-effects.

There are also natural ways you can reduce your blood pressure as well, including changing your diet, increasing exercise, giving up smoking and losing weight. In fact, I personally reduced my blood pressure to normal using a combination of these “natural methods”. You should also be aware that changes to your exercise and diet can be responsible for more than just lowering your blood pressure. Being more careful with the food you eat and doing a little more exercise can help reduce factors such as stress, heart disease, cholesterol, arthritis and prevent onset of diabetes.

Don’t risk being the next victim of the silent killer.

Hypertension – High Blood Pressure

Blood pressure is a measure of the outward force exerted by the blood on the arteries in your body. A healthy body has a blood pressure that is just enough to push the blood into all of the smaller blood vessels of your body, called capillaries.

Blood pressure is created by a combination of factors in your body:

1. Force of the heart pushing blood out of the heart chambers into the aorta.
2. The volume of blood you have circulating in your circulatory system.
3. The size of the blood vessels that the blood has to travel through. As the diameter of the blood vessels decrease, it requires greater pressure to push blood through.

Your body has various systems in place to keep your blood pressure within very strict limits. Negative feedback systems are in operation. Sensors in your carotid artery and wall of the aorta monitor blood pressure, and if it gets too high, a signal is sent to the medulla in your brain, which in turn reduces your heart rate, and increases vasodilation (opening up) in blood vessels (called arterioles). This means the same volume of blood is distributed between more blood vessels, so overall blood pressure drops. When blood pressure drops, the opposite happens. Heart rate increases, and vasoconstriction (closing off) occurs in arterioles.

Things can and do go wrong

Various factors can cause high blood pressure (which is called hypertension by the medical community).

There are varying opinions on what measurements actually constitute high blood pressure, but the majority of source agree that:

Greater than 140 mmHg Systolic Pressure, and greater than 90 mmHg diastolic pressure is high. If you have two or more readings taken on different occasions, you may be diagnosed as having hypertension.

Symptoms & Signs of High Blood Pressure

Unfortunately high blood pressure has very few (if any) symptoms, and is often called the “Silent Killer”. You should go to your doctor and get your blood pressure checked frequently. Alternatively you could buy a personal digital blood pressure monitor and make the measurements at home. It could save your life.

What Causes of Hypertension

In most cases, the cause of hypertension is unknown. However, there are some factors which can contribute to it.

• Excessive alcohol
• Tobacco
• Obesity
• Salt in the diet
• genetic factors

Blood pressure can also increase in pregnancy, when the patient has kidney problems, or hormonal problems like an over-active thyroid, and even sleep apnea (a condition which causes the sufferer to stop breathing for a short time when asleep).

There are also some medications that can cause increased blood pressure including antacids, oral contraceptives, decongestants and diet pills. Please read the notes that come with any medication you are taking for details on possible blood pressure side-effects.

Risks of Hypertension

If your blood pressure is too high, your heart and arteries are put under stress, and can hate fatal consequences.

• Hypertension causes damage to the walls of your arteries causing them to become less elastic. This hardening of the arteries makes it much easier for harmful cholesterol to stick to your artery wall, reducing the diameter of the blood vessel through which blood must flow. With narrowing of the arteries, your heart must work much harder to push the blood through, and blood pressure rises. Possible consequences include heart attack, stroke, kidney failure, or even the amputation of the leg.
• Risks of heart attack and stroke are greatly increased in patients with high blood pressure.
• Heart enlarges which can cause heart attack.
• Bulging of the arteries outwards. These aneurysms can rupture, leading to blood spilling out into surrounding tissues. If this occurs in the brain, the patient will likely suffer a stroke.
• Blood vessels in the kidneys narrow possibly leading to renal failure.
• Blood vessels in the eyes can burst, causing a deterioration in sight, even blindness.

Controlling High Blood Pressure Naturally

Hypertension (high blood pressure) is often called the silent killer, due to the fact that there are few, if any symptoms. People go about their daily lives unaware of the time-bomb ticking away inside them.

It is vitally important that you keep checks on your blood pressure, and if high, seek medical help. While blood pressure medications can help reduce a dangerously high blood pressure, they often do have side-effects. In my own case, I wanted to find ways to help control my blood pressure naturally, and within a couple of months, my blood pressure was largely under control. The following tips are for information only. Please consult your doctor if you have high blood pressure.

Tips for controlling blood pressure

• Reduce alcohol intake if you drink more than three alcoholic beverages a day. Small amounts of alcohol don’t seem to affect blood pressure in the same way, but heavy drinkers will benefit from reducing alcohol intake.
• Drink plenty of fresh water – your body is made up of a high percentage of water. If you don’t drink enough, your body tries to hold onto it, causing bloating. By drinking water regularly throughout the day, your body can detoxify your body. Your urine can be a good gauge to whether you are drinking enough water. The darker it is, the more dehydrated you are.
• Increase levels of activity – this will exercise your heart. Studies regularly show that increased exercise will help lower blood pressure.
• Lose weight if you need to – if you are over-weight, your heart has to work harder to pump blood around your body. Losing weight can reduce blood pressure, and you’ll feel a lot better as well.
• Reduce salt intake – your body does require salt, but in most cases, it can be supplied in sufficient doses by eating a balanced diet. Foods contain salt, so you don’t need to add extra. Since sodium (a component of salt) is involved in regulating body fluids, it can play a role in high blood pressure. If you eat canned products, read the labels. Look for food sources low in sodium.
• Avoid food high in fat or cholesterol.
• Stop smoking – nicotine has been shown to constrict blood vessels (making them narrower), raising the pressure in the vessels.
• Reduce Caffeine intake – My morning coffees are an important part of my daily routine, but I found that by having one caffeine coffee, and then switching to decaffeine coffee for the rest of the morning, I could have the best of both worlds, while helping to reduce my blood pressure.

Prior to following these tips, my blood pressure regularly reached 140/90 and even 140/100. After two months of following these tips, my blood pressure was normal, and often as far down as 115/68. These tips were responsible for controlling my high blood pressure, and meant that I could avoid going onto drugs. If you decide to try the natural route, please do consult your doctor first. The above information does not constitute medical advise.

What is blood pressure?

Definition: Blood pressure is simply the pressure of your blood pushing out on your arteries as the blood circulates your body.

The pressure of your blood depends on a number of factors including:

• the force created by your heart pumping blood into your arteries
• the volume of your blood
• the resistance your blood encounters as it moves through your blood vessels.

You body needs to make sure that there is sufficient pressure to push the blood into all of the capillaries around your body. Capillaries are the smallest blood vessels in your body, and ensure that all cells in your body receive nutrients they require to live.

Maintaining normal blood pressure is delicately balanced. Too high, and your heart and blood vessels are put under strain. Too low and the low blood pressure means some cells may not get the nutrients they require.

High blood pressure is often called the “Silent Killer” since there are often no symptoms. For this reason, it is important you get your blood pressure checked regularly.

Blood pressure readings can be taken by your doctor using a sphygmomanometer and stethoscope, or at home using a blood pressure monitor (the easiest ones to use are digital monitors). The home monitors generally come in two forms. One places a cuff around your wrist, while the other places a cuff around your upper arm (level with your heart). I personally have tried both types and found the most accurate one to be the upper arm cuff.

The blood pressure “numbers”

The blood pressure reading is two numbers. These are the two pressures of your blood at varying stages of your heart beat cycle:

The larger number is the systolic pressure, the lower number is the diastolic pressure.

Systolic pressure is the blood pressure being pumped into the aorta when the heart beats.

Diastolic pressure is the blood pressure in the arteries when the heart relaxes between beats.

Blood pressure does vary with age, sex and health, but in general, a healthy blood pressure is 120/80, or 120 over 80.

This means that systolic blood pressure is 120 mmHg, and the diastolic blood pressure is 80 mmHg.

Your blood pressure can actually tell a doctor a lot about the health of your heart and blood vessels. High blood pressure means that your heart is having to work harder to push your blood to all the cells in your body.

This can happen if e.g. you have narrowing of the arteries, since this narrowing increases the resistance of your blood vessels, and requires more pressure to get the blood through.

High blood pressure is also called hypertension, and can have serious consequences if not treated. e.g. high blood pressure can weaken the artery walls, and lead to rupture. If this happens in the brain, it can lead to a stroke.

There are a wide range of medicines and medications available to treat high blood pressure, and some alternative therapies such as acupuncture may also help, but you can also take immediate steps by looking at your diet and increasing your daily exercise (walking is a great exercise).
