High Blood Pressure Symptoms

High blood pressure usually causes no symptoms and high blood pressure often is labeled "the silent killer." People who have high blood pressure typically don't know it until their blood pressure is measured.


Sometimes people with markedly elevated blood pressure may develop

• headache, 
• 
  
• dizziness, 
• 
  
• blurred vision, 
• 
  
• nausea and vomiting, 
• 
  
• chest pain and shortness of breath.

People often do not seek medical care until they have symptoms arising from the organ damage caused by chronic (ongoing, long-term) high blood pressure. The following types of organ damage are commonly seen in chronic high blood pressure:

• Heart attack 
• 
  
• Heart failure 
• 
  
• Stroke or transient ischemic attack (TIA) 
• 
  
• Kidney failure 
• 
  
• Eye damage with progressive vision loss

Peripheral arterial disease causing leg pain with walking (claudication)


Outpouchings of the aorta, called aneurysms
About 1% of people with high blood pressure do not seek medical care until the high blood pressure is very severe, a condition known as malignant hypertension.


In malignant hypertension, the diastolic blood pressure (the lower number) often exceeds 140 mm Hg. 
Malignant hypertension may be associated with headache, lightheadedness, nausea, vomiting, and stroke like symptoms
Malignant hypertension requires emergency intervention and lowering of blood pressure to prevent brain hemorrhage or stroke.
It is of utmost importance to realize that high blood pressure can be unrecognized for years, causing no symptoms but causing progressive damage to the heart, other organs, and blood vessels.

High Blood Pressure Causes


In 90% of people with hypertension, the cause of high blood pressure is not known and is referred to as primary or essential hypertension. While the specific cause is unknown, there are risk factors that can contribute to developing high blood pressure.

Factors that can not be changed

• Age: The older a person is, the greater the likelihood that he or she will develop high blood pressure, especially elevated systolic readings. This is largely due to arteriosclerosis, or "hardening of the arteries." 
• Race: African Americans develop high blood pressure more often than Caucasians. They develop high blood pressure at a younger age and develop more severe complications sooner in life. 

Socioeconomic status: High blood pressure is found more commonly among the less educated and lower socioeconomic groups. Residents of the southeastern United States, both Caucasian and African American, are more likely to have high blood pressure than residents of other regions

• Family history (heredity): The tendency to have high blood pressure appears to run in families. 
• 
  
• Gender: Generally men have a greater likelihood of developing high blood pressure than women. This likelihood varies according to age and among various ethnic groups.

Obesity: As body weight increases, the blood pressure rises. Obesity is defined as having a body mass index (BMI) greater than 30 kg/m . A BMI of 25-30 kg/m  is considered overweight (BMI=weight in pounds x 703/ height in inches  ) Being overweight increases the risk of high blood pressure. Health care practitioners recommend that all obese people with high blood pressure lose weight until they are within 15% of their healthy body weight.

Obese people are two to six times more likely to develop high blood pressure than people whose weight is within a healthy range. 

Not only the degree of obesity is important, but also the manner in which the body accumulates extra fat. Some people gain weight around their belly (central obesity or "apple-shaped" people), while others store fat around their hips and thighs ("pear-shaped" people). "Apple-shaped" people tend to have greater health risks for high blood pressure than "pear-shaped" people.

Sodium (salt) sensitivity:

Some people have high sensitivity to sodium (salt), and their blood pressure increases if they use salt. Reducing sodium intake tends to lower their blood pressure. Americans consume 10-15 times more sodium than they need. Fast foods and processed foods contain particularly high amounts of sodium. Many over-the-counter medicines also contain large amounts of sodium. Read food labels and learn about salt content in foods and other products as a healthy first step to reducing salt intake. Fast food restaurants also make the salt and calorie content of their food available to consumers at their restaurants........
