What is Hypertension or High Blood Pressure?

High blood pressure or hypertension is a chronic condition, which usually lasts a lifetime once it is developed.(1 Trusted Source
High Blood Pressure Also known as Hypertension

) It is defined as the force of the blood against the artery walls as the heart pumps the blood around the body. Each time the heart beats, it pumps out blood into the arteries. Hypertension is a ‘silent killer disease’ and it often presents without any signs and symptoms.


There are two measurements when a blood pressure reading is taken(2 Trusted Source
Measuring Blood Pressure

Go to source
) -

  • Systolic Pressure
  • Diastolic Pressure.

Systolic pressure refers to blood pressure, when the heart beats while pumping blood and Diastolic Pressure refers to blood pressure, when the heart is at rest between beats.

Blood pressure is measured in millimeters of mercury (mmHg). Sphygmomanometer is a device used to measure the blood pressure The normal recommended blood pressure is 120/80 mmHg. If the blood pressure measurement is between the range of 120/80 mmHg and 140/90 mmHg, it is termed as ‘pre-hypertension’.(3 Trusted Source

If hypertension is left untreated it can increase the risk of heart disease, stroke, Kidney failure and eye damage. Some people may not realize they have high blood pressure until they have problems with their blood, heart or kidneys.

Facts on Hypertension

  • Globally, 970 million people suffer from Hypertension(4 Trusted Source
    High Blood Pressure Facts

    Go to source
  • About 1.56 billion adults will develop hypertension by 2025.
  • It is the leading cause of cardiovascular disease (CVD) worldwide.
  • It is one of the most important causes of premature deaths worldwide and the problem is growing.
  • People with hypertension are more likely to develop complications of diabetes.
  • Almost one in every three people suffers from this condition, and this may be related to our modern sedentary lifestyle and dietary habits.

How do you Classify Hypertension?

The cause of hypertension may not be known or there maybe a known cause and accordingly it can be classified(5 Trusted Source
Primary and Secondary Hypertension

Go to source
) -

  • Primary (essential) hypertension - High blood pressure with no obvious underlying medical cause.
  • Secondary hypertension - High blood pressure caused by conditions that may affect the kidneys, arteries, heart or endocrine system.

What are the Factors that can Lead to Primary or Secondary Hypertension?

The causes of high blood pressure may vary according to individuals.(6 Trusted Source
Know Your Risk - Blood pressure

Go to source

In 90 - 95% cases of high blood pressure, there is no specific underlying medical condition. When the cause is unknown, it is known as essential hypertension or primary hypertension.

The following factors contribute to primary hypertension:

  • High intake of salt
  • Hereditary (genetic) susceptibility (30%)
  • Obesity
  • Kidney failure (renal insufficiency)
  • Lack of physical activity
  • Aging inflammation
Causes of Primary Hypertension

The remaining 5-10 % cases of hypertension are due to certain factors that can be corrected. This is known as secondary hypertension.

Causes of Secondary Hypertension:

  • Narrowing of certain arteries
  • Kidney abnormality
  • Adrenal gland diseases
  • Thyroid diseases
Causes of Secondary Hypertension

What are the Known Risk Factors for Hypertension?

  • Age - Blood pressure increases as age increases.
  • Race - High blood pressure is more common in blacks than in whites.
  • Sex - It has been seen that young men and men during early middle age have high blood pressure more often than women.
  • Genetics - High blood pressure tends to run in families

What are the Symptoms of High Blood Pressure?

Most people with high blood pressure have no signs or symptoms.

However, people with high blood pressure might sometimes notice the following symptoms:

  • Headaches
  • Dizziness
  • Shortness of breath
  • Blurred vision
  • Nosebleeds (epistaxis)
  • Rapid or irregular heartbeat (palpitations)
  • Nausea
  • Vomiting
Symptoms of Hypertension

If any one or more of the symptoms are present, these are warning signs and it is essential to get the blood pressure measured on more than one occasion.

How is Blood Pressure Measured?

Blood pressure is measured with a small, portable instrument called a Sphygmomanometer.(7 Trusted Source
How High Blood Pressure is Diagnosed

Go to source
) The blood pressure instrument basically consists of an air pump, a pressure gauge, and a rubber cuff. The instrument registers the blood pressure in units called millimeters of mercury (mmHg).

The cuff is placed around the upper arm and inflated to a pressure that blocks the flow of blood in the main artery (brachial artery) that travels through the arm. Then, the pressure in the cuff on the arm and artery is gradually released. As the pressure decreases, the health practitioner listens with a stethoscope over the artery at the front of the elbow.

The pressure at which the practitioner first hears a pulsation over the artery is the systolic pressure. As the cuff pressure decreases further, the pressure at which the pulsation finally stops is the diastolic pressure.

Blood pressure maybe measured both sitting up and lying down.

How do You Diagnose High Blood Pressure?

The initial assessment of the hypertensive people includes a complete history and physical examination.

High blood pressure is usually diagnosed on the basis of a persistently high blood pressure measured with a sphygmomanometer.

One reading is not sufficient for this purpose and three separate sphygmomanometer measurements are taken at one-week intervals.

The blood pressure readings decide the severity of hypertension –

Average Blood Pressure
For young people120/80 mmHg
For old people140/90 mmHg
Level of SeveritySystolic Blood Pressure (mmHg)Diastolic Blood Pressure (mmHg)
Mild Hypertension140-16090-100
Moderate Hypertension160-200100-120
Severe HypertensionAbove 200Above 120

What Investigations Maybe Required for Hypertension?

The doctor may also ask the patient to undergo the following tests -

  • Blood tests - Complete blood count (CBC), electrolytes level, BUN (blood urea nitrogen) and creatinine level are done to assess the risk factors for heart disease and stroke.
  • ECG (electrocardiogram) - To evaluate heart rate and rhythm.
  • Echocardiogram - It is an ultrasound examination of the heart and is used to evaluate the anatomy and the function of the heart.
  • Chest X-ray - To assess the heart size, the shape of the aorta and the lungs.
  • Doppler ultrasound - To assess the blood flow through arteries at pulse points in the arms, legs, hands and feet.

What is New in High Blood Pressure?

1. Low-dose 'Triple Pill' Helps Lower Blood Pressure Better

New method combines low-dose of three blood pressure-lowering drugs to lower high blood pressure. Combining these drugs in a single pill makes it easier for doctors to prescribe treatment and also for patients to take it. The 'triple pill' is more effective and safer than other usual drugs. "The most urgent need for innovative strategies to control blood pressure is in low- and middle-income countries. The Triple Pill approach is an opportunity to 'leap frog' over traditional approaches to care and adopt an innovative approach that has been shown to be effective," said Webster.

2. Heart Rate Increase, Fall In Blood Pressure Combo Test Can Help Diagnose Brain Diseases

Patients whose blood pressure drops after standing up without an accompanying increase in their heart rate may have a synucleinopathy, finds a study led by neurologists at the New York University (NYU) School of Medicine.

This simple bedside test could help doctors diagnose certain degenerative brain diseases called synucleinopathies which include Parkinson's disease, Lewy Body dementia, and multiple system atrophy.

3. Are Pills a Good Substitute for Exercise to Overcome High Blood Pressure?

People with high blood pressure are more likely to choose anti-hypertensive pills and tea over an hour of exercise finds a new survey. When compared to the overall percentage only 63 percent said they would be willing to exercise to control their high blood pressure.

How can Hypertension or High Blood Pressure be Treated?

Blood pressure normally will rise and falls throughout the day in response to our daily activity and what we are doing and how our emotions get affected by our surroundings. If you are angry the blood pressure will go up but once you have calmed down the pressure will come down. However if the pressure does not come down and remains higher than normal on more than one reading high blood pressure or hypertension is suspected and may warrant regular treatment. Once you start the treatment you should not stop it without consulting your doctor.

Lifestyle modification is the first step in treating early hypertension, however if it fails to bring down the pressure medications are added. However if the blood pressure is very high, medication will be started without waiting for the results after lifestyle modification.


Diuretics, beta-blockers, ACE inhibitors and calcium channel blockers can be used for treating hypertension.(8Treatment - High blood pressure (Hypertension)

Go to source

Diuretics - These medications act on kidneys to help the body eliminate sodium and water, reducing blood volume.

Beta-blockers- These medications block the effects of certain adrenaline-related chemicals, causing the heart to beat more slowly and less forcefully.

Angiotensin-converting enzyme (ACE) inhibitors - These medications help relax blood vessels by blocking the formation of a naturally occurring chemical that narrows blood vessels.

Calcium antagonists - Calcium antagonists are also known as calcium channel blockers. These medications help relax the muscles of blood vessels.

Diet and Lifestyle Modifications

Adopting healthy lifestyle habits is an effective first step in both preventing and controlling high blood pressure

  • Study shows that hypertension is reduced by an eating plan and cutting down on table salt. The eating plan should include fruits, vegetables and low-fat dairy foods. The diet should include whole grains, poultry, fish and nuts and have reduced amounts of fats, red meats, sweets, and sugar sweetened beverages.
  • Including foods high in potassium can lower your blood pressure
  • Quit smoking and limit your alcohol intake.
Ways to Control High Blood Pressure

Weight management:

  • Normal weight is another factor that is crucial when trying to prevent hypertension. People who are overweight should lose weight, and people of normal weight should avoid adding on extra pounds.
  • Exercise regularly. Get moving to prevent hypertension. Regular to moderate exercise for about 30 - 40 minutes three times a week can help manage or control high blood pressure.

Monitor your blood pressure levels regularly either at home or visit the general practitioner.

‘Health is correlated with quality of life. If you get regular physical activity, have social connections, control your cholesterol, keep your blood pressure at a normal level, don't smoke - these things can make an enormous difference not only in how long you live, but how much you enjoy your life in those years’. ~ Tom Frieden

I am 47 yrs-male got tested BP@ Appolo Free Camp and noted result as 146/104. pls.adv.... Regards Srinath


A Comprehensive Genetic Testing is advised for all patients suffering from high blood pressure or hypertension to rule out the possible chronic complications like organ damages.


i am 39yrs old with hbp i take sigle medicine telma40mg pls give me a advice actual treatment 146/95, 140/90 sometimes 130/85 I have no idea what we do cn i take sarpgandha tab. Pls advice.


I am a 56 year old teacher with HBP. I take 2 medications. While at an antique show I signed up for a free x-ray and consultation at a local chiropractic office. The first visit the doctor took the x-ray, the second he went over the results. I was shocked to see that the top part of my spine was out of alignment. I agreed to having my spine adjusted to get it straight. The doctor proceeded to crack my neck. The next day, I remembered that I had this deep pain in my neck noticeable only when I pressed in firmly. It has been there for years. I decided to check it and was AMAZED that it was gone ! I have had 3 adjustments. Last night I decided to check my blood pressure because during my research about spine adjustments I read that it can lower high blood pressure and the reasons why made sense. Well, you guessed it- my blood pressure was 122/76! I took several readings. I will continue to check as I continue my therapy. My BP before was 140s-150s/80s-90s for years even on BP meds. Checkout how your spine alignment relates to HBP. Hope this helps someone out there!


Its really wonderful to know that spine alignment is linked to BP...!! thank you for your post..
