What is High Blood Pressure?

High Blood Pressure is a situation of physical inconveniences that when your blood pressure increases out of normal state.

In other words, we can say that high blood pressure is a physical condition that the pressure of blood pushing against the walls of your arteries. The function of arteries is to contain blood from your heart to other parts of your body.

Usually, hypertension is a silent physical condition. Most people with high blood pressure won’t experience any signs & symptoms of high blood pressure.

Its signs only appear only when it reaches its extreme severity. Hence, all should go through a regular physical examination to track high blood pressure or hypertension after discussing with their doctors.


Common signs & symptoms that people with hypertension usually face, such as:


  • Nosebleeds

Your doctor is most likely to recommend this also. This will help you to measure the signs of high blood pressure before reaching it too extreme.

Readings of High blood pressure:

To control your high blood pressure or hypertension, you need to have a full understanding of your blood pressure chart or numbers.

If you explain those readings or numbers properly, you will be able to keep your high blood pressure at a healthy level. Normally, the unit of measurement for high blood pressure is known as millimeters of mercury (mmHg).

Usually, your total blood pressure is measured by two numbers:

Systolic blood pressure:

The top number is known as systolic blood pressure. It means a physical condition when your heart beats to push blood through your arteries to your entire body.

This force creates a strong pressure on those blood vessels. This state of condition is called systolic blood pressure.

 A normal range of systolic pressure is 120. If it exceeds more than 140 that means you’ve high blood pressure symptoms.

Diastolic pressure:

It usually refers to the bottom number. This is a physical condition when your heart muscle is between beats. During this time, the heart fills with blood & gets oxygen.

 The ideal diastolic blood pressure range exists below 80. If your readings exceed 90 or more then you have high blood pressure problems.

 Here, we’re explaining the top 5 categories of high blood pressure:

Normal Reading:

According to American Heart Association (AHA), the ideal number of Systolic pressure (top number) should be between 90 & less than 120.

 On the other hand, the standard number of diastolic pressures should remain between 60 & less than 80.

Usually, a normal reading would be the ideal condition when any blood pressure stays below 120/80 mmHg & above 90/60 mmHg.

When an adult belongs to the normal blood pressure range, they need no medical intervention. But keep this ideal situation continuing, need to maintain a healthy diet & regular exercise for the adults.

Elevated blood pressure:

Elevated blood pressure is a physical condition when blood pressure readings exist between 120-129 systolic & less than 80 mmHg diastolic.

There’s a risk associated with elevated blood pressure if it remains untreated. It might turn out high blood pressure.

Even there is a high potentiality of having heart diseases & strokes.

Hypertension: Stage 1:

Hypertension: Stage 1 is a physical condition when blood pressure number ranges between 130-139 systolic or diastolic pressure reaches between 80-89 mmHg.

 Under the hypertension stage 1 situation, the doctor will track your blood pressure carefully. Even they offer medications if the situation wouldn’t improve despite following a healthy lifestyle.

As per the American Heart Association (ASA), only one reading will never determine that you have blood pressure.

 The doctor will decide after evaluating the average of blood pressure ranges revealed over the period.

For people with high blood pressure whose age is 65 or more, the doctor usually follows different types of treatment procedures.

If systolic blood pressure of this age range exists more than 130 mm Hg, the doctor might suggest medications & lifestyle changes.

Hypertension: Stage 2:

Hypertension: Stage 2 is a quite severe physical condition. If blood pressure readings belong between 140 for systolic & 90 for diastolic, this situation is known as stage 2 hypertension.
The doctor usually suggests medications & lifestyle changes in this stage.


Some medications might consume in this stage:

  • Alpha-blockers for comforting arteries
  • Beta-blockers reduce heart rate & make flexible blood vessels.
  • Calcium channel blockers relax the blood vessels.
  • ACE inhibitor for removing substances that hardened blood vessels.
Hypertensive Crisis:

A hypertensive crisis is a condition if the blood pressure readings suddenly crossed 180/120 mmHg.
Before reaching a decision, do your blood pressure readings again. If the result is the same as the previous then communicate to your doctor immediately.

During this stage, you may encounter a few symptoms like as below:

  • Visual changes

High Blood Pressure & Covid-19:

During this Covid-19 outbreak, people with high blood pressure might face severe complications if they are infected with this virus.


What is the real risk?


There is evidence found that elderly people with having heart disease or hypertension are more likely to develop covid-19 symptoms.


Therefore, it’s just critically important to maintain healthy guidelines for diet, medications & lifestyles to lower the symptoms of high blood pressure.


Early data of both China & the US reveals that almost 30% to 50% of hospitalized Covid-19 patients have pre-existing cases of high blood pressure.


Even in Italy, a report discloses that 76% out of 99% of people who have died from the virus had high blood pressure symptoms.


Why do people with high blood pressure are more likely prone to Covid-19?


The reason behind this is the vulnerable immune system. Aging & long- term health conditions weaken the overall immune system of people having high blood pressure.


There’re some misconceptions rose that few medications for high blood pressure are riskier to infect Covid-19. These medicines are ACE inhibitors & angiotensin receptor blockers (ARBs).


This idea is based on the fact that ACE inhibitors & ARBs instigate an enzyme called ACE2 in the body. When the Covid-19 virus infects cells, they need to link with ACE2.


Though some studies revealed that, there’s no proof that after stopping those drugs, Covid-19 will be less severe for those people.


According to the American College of Cardiology & American Heart Association, people with high blood pressure shouldn’t quit their prescribed medicine. If you don’t follow the medical recommendation, the number of cardiac patients will be outweighed the number of Covid patients in the hospital.
