High Blood Pressure (Hypertension)

What is high blood pressure?

most of the people having high BP(HYPERTENSION) they suddenly got angry and sometimes be cool.their behaviour is changing time to timeYou probably have high blood pressure (hypertension) if your blood pressure readings are consistently 140 over 90, or higher, over a number of weeks.

You may also have high blood pressure if just one of the numbers is higher than it should be over a number of weeks.

If you have high blood pressure, this higher pressure puts extra strain on your heart and blood vessels. Over time, this extra strain increases your risk of attack or stroke

High blood pressure can also cause heart and kidney disease, and is closely linked to some forms of dementia

High blood pressure (hypertension) is defined as high pressure (tension) in the arteries, which are the vessels that carry blood from the heart to the rest of the body.

IT CAUSE heart disease, kidney (renal) disease, hardening of the arteries (atherosclerosis or arteriosclerosis), eye damage, and stroke (brain damage).

Hypertension is a major public health problem. The American Heart Association estimates high blood pressure affects approximately one in three adults in the United States, or about 76.4 million people.

What causes high blood pressure?

 

The causes of hypertension are multifactorial, meaning there are several factors whose combined effects produce hypertension.

  • High salt intake or salt sensitivity: This occurs in certain populations such as the elderly, African Americans, people who are obese or people with kidney (renal) problems.
  • Genetic predisposition to high blood pressure: People who have one or two parents with hypertension have high blood pressure incidence about twice as high as the general population.
  • A particular abnormality of the arteries, which results in an increased resistance (stiffness or lack of elasticity) in the tiny arteries (arterioles): This increased peripheral arteriolar stiffness develops in individuals who are also obese, do not exercise, have high salt intake, and are older.

What are the signs and symptoms of high blood pressure?

 

High blood pressure may not have any symptoms and so hypertension has been labeled “the silent killer.” Longstanding high blood pressure can lead to multiple complications including heart attack,kidney disease or stroke

Some people experience symptoms with their high blood pressure. These symptoms include

  • Shortness of breath
  • blurred version
  • Feeling of pulsations in the neck or head
  • headache

What is the treatment for high blood pressure?

 

Blood pressure is caused by many different factors, so there are many different treatments. The goal of treating high blood pressure is to keep the blood pressure below 140/90.

Treatments for high blood pressure include:

  • Lifestyle modifications:
    • Exercise
    • Avoid alcohol
    • Eat a low-sodium, low-fat diet
    • Quit smoking
    • lose weight
  • Medications: There are many different categories of blood pressure medications. Your doctor will work with you to find the right one. The main types include:
    • beta blockers
    • Angiotensin converting enzyme (ACE) inhibitors
    • Angiotensin II Receptor (ARB) blockers
    • calcium channel blokers
    • Diuretics (water pills)
  • Treatment of underlying conditions that cause high blood pressure, such as:
    • congestive
    • diabetes
    • obesity
  • What are risks and complications of untreated high blood pressure?

    Complications of hypertension are often referred to as end-organ damage because damage to the organs is the end result of chronic (long duration) high blood pressure.

    High blood pressure increases the risk of developing:

    • heart disease: Increased workload on the heart from pushing against the high blood pressure can cause enlargement of the heart muscule,heart failure, coronary, and cardiac arrhythmias.
    • Hardening of the arteries (atherosclerosis): Increased pressure through the arteries and arterioles causes damage to the inner walls of the blood vessels, resulting in hardened arteries.
    • Increased risk of aneurysms: Increased pressure can also cause stretching or dilation of the blood vessels, which can result in aneurysms.
    • Eye damage: The sensitive tissues within the eyes are prone to damage from high blood pressure.
