Hypertension, or high blood pressure, is the most common cardiovascular disorder affecting populations across the world. Blood pressure actually indicates the force of blood pushing against artery walls as it flows through the arteries or blood vessels in the human body. Blood vessels get filled by blood up to a certain capacity. Too much pressure of blood on the vessel wall, or high blood pressure, can threaten healthy arteries and lead to life-threatening conditions such as heart disease and stroke. High blood pressure is hazardous due to its propensity to cause strokes, heart attacks, heart failure, or kidney disease. Everybody should be aware about his/her blood pressure.
Treatment strategies to manage high blood pressure include changing lifestyle suitably and possibly drug therapy to lower blood pressure to less than 140/90. For patients who have diabetes or chronic kidney disease the recommended blood pressure is less than 130/80. Aim of management is to lower high blood pressure and protect important organs, like the brain, heart, and kidneys from damage. Research has found that treatment for hypertension causes a significant reduction in stroke (reduced an average of 35%-40%), heart attack (20%-25%), and heart failure (more than 50%).
It is not known exactly what causes high blood pressure. But, there exist several factors and conditions that may play a role in its development. These factors include:
As per the guidelines the normal blood pressure should remain within 120/80 mm Hg. A very stringent life style modification is recommended in terms of diet control & modest exercise if the blood pressure ranges in between 120-139/ 80-89 mm Hg & medical treatment is recommended if the blood pressure is more than 140/90 mm Hg. High blood pressure tends to run in families and is more likely to affect men than women. Increasing age and race also play a role in causation. Diet and lifestyle also greatly affect es hypertension. Other factors that can raise the risk of having hypertension include obesity; diabetes; stress; insufficient intake of potassium, calcium, and magnesium; lack of physical activity; and chronic alcohol consumption.
Most of the patients may not even know that they have hypertension. The only way to know if your blood pressure is high is through regular checkups. Some patients do have certain symptoms, especially if their blood pressure is extremely high. These are:
In case anybody has these symptoms, a doctor should be consulted immediately. Hypertension that is not treated or poorly treated can lead to stroke, heart disease, kidney failure and eye problems.
Hypertension is often called a "silent disease" as the patient usually doesn't know about it. There may be no symptoms or signs. But, it keeps on damaging your body. So, it's important to regularly monitor your blood pressure. Tests should be conducted for heart disease as hypertension is a risk factor for heart disease.
Blood pressure is measured in mm hg. Most often, blood pressure is measured with a device known as a sphygmomanometer. Blood pressure is measured in two ways: systolic and diastolic. Systolic blood pressure is the maximum pressure during a heartbeat. Diastolic blood pressure is the lowest pressure between heartbeats. According to the most recent guidelines, a normal blood pressure is less than 120/80 mm Hg. Hypertension is blood pressure that is greater than 140/90, while prehypertension consists of blood pressure that is 120 to 139/80 to 89. Apart from BP measurement, your doctor will ask about your medical history (whether you've had heart problems before), assess your risk factors (whether you smoke, have high cholesterol, diabetes, etc.), and talk about your family history (whether any members of your family have had high blood pressure or heart disease).
Any patient with BP readings greater than 120/80 should be encouraged to enroll for treatment planning. This includes lifestyle modifications, such as eating a healthier diet, quitting smoking, and getting more exercise. Treatment with medication is recommended to lower blood pressure to less than 140/90. For patients who have diabetes or chronic kidney disease the recommended blood pressure is less than 130/80.
Treating high blood pressure involves lifestyle changes and possibly drug therapy.
Your doctor may prescribe one or more prescription medicines to help lower your blood pressure in addition to taking steps such as losing weight and exercising. Most of the medications prescribed for treatment of hypertension help lower your chances of developing health problems such as stroke, kidney disease, or heart attack.
In these times, a lot of drugs from various categories of antihypertensives are available that can effectively help most people lower their blood pressure and reach the blood pressure goal set by their health care provider.
Different medications prescribed for control of blood pressure work in many different ways. Some remove extra fluid and salt from the body. Others slow down your heartbeat or relax and widen your blood vessels. In market, there are more than 100 blood pressure–lowering drugs available. Some of them, like diuretics, have been in use for more than 50 years. Many pills prescribed for high blood pressure contain a combination of two different types of medicines. Combining two different types of drugs can make it easier to control blood pressure by two different mechanisms. These combination pills also keep track of taking your medicines.
Do keep in mind that since combination pills contain more than one medicine, they also have the potential for more side effects than pills that contain just one medicine. Report anything unusual to your doctor while you are taking pills for hypertension.
Different types of medications work differently for different types of patients, with varying age and body profile. In fact, some medicines have been found to provide more benefits for men than women or younger than in older populations. Your doctor will provide a medicine that is right for you.
Reduction of blood pressure with medication will prevent progression from less severe to more severe hypertension, will prevent enlargement of the heart and heart failure, and will dramatically reduce strokes, stroke deaths, and heart attack deaths. Getting blood pressure down to below 140/90 mm Hg, or below 130/80 mm Hg if you have diabetes or kidney disease, if at all possible, is a good idea at all ages. Do remember that even if you are taking your medications regularly, it is important to keep on exercising and eating as advised by your health care provider.
