What is Blood Pressure

Many people ignore blood pressure and later they have to face diseases. People on the internet want to know about blood pressure, so in this article complete information about blood pressure has been given. So let’s know what is blood pressure ?

The pressure exerted on the walls of the vessels by the blood flowing in the blood vessels is called blood pressure. Arteries carry out the work of carrying blood to all the tissues. The heart plays the most important role in blood pressure.

He makes the blood flow. Arteries and heart together form a system which makes our body healthy. If this system gets disturbed then diseases start to form. When the arteries are unable to flow blood properly, the body becomes unhealthy and the blood pressure becomes high and low. Below you have been told about high blood pressure and low blood pressure.

How is Blood Pressure Measured ?

By pumping the heart, it conducts oxygen and blood to every organ in the whole body. To deliver the blood to the organ, it generates hard pressure, which leads to impact and circulation of blood. There are two points of blood pressure in medical terminology. This is the following-


  • Systolic blood pressure
  • Diastolic Blood Pressure

Systolic blood pressure-

When the heart pumps i.e. in the systolic state, then the pressure with which the blood hits the arteries of the body is called systolic blood pressure.

Diastolic blood pressure-

When one is in a hard relaxing mood die settling, even at that time a minimum pressure is maintained for the blood to circulate which is called diastolic blood pressure. It maintains some amount of pressure on the walls of the arteries even in the normal state of the blood in the relaxing mode.

How is Blood Pressure Measured

The machine used to measure blood pressure is called a Sphygmomanometer. It is of two types-

  1. Manual Sphygmomanometer
  2. Electrical Sphygmomanometer

The Manual sphygmomanometer is commonly seen in clinic, hospital or medical. It is of three types-

  • Mercury Bass
  • Electrical Bass
  • Air Pressure Bass

Electrical Sphygmomanometer- Electronic blood pressure machine commonly seen in homes. We call this electric Sphygmomanometer. It is generally used for routine checkups in homes. Let us see how blood pressure is checked-

Let us first know how to use a manual sphygmomanometer – it is commonly used by the doctor and nurse staff in clinics and hospitals.

In using a mercury base sphygmomanometer, there is a further acuity requirement which is called status scope. First of all, the patient has to sit in a comfortable position. The hand should be in absolutely relaxing mode. Keep the feet completely relaxed. First the ear bladder is wrapped around the arm. While tying the ear bladder, care is taken that it should not be too tight or loose.

To measure blood pressure, first the strength is set and after that through ear force, we create pressure in it, due to which the level of mercury starts increasing. As a result, pressure has been generated in the air bladder. Now slowly this thing is released and then the pressure of mercury starts coming down. During this, we have to keep in mind that the point at which we hear the beat is our systolic blood pressure and the point at which the heartbeat stops is our diastolic blood pressure. In this way you can measure your blood pressure.

What is high blood pressure ?

When the pressure of blood flow on the artery walls becomes excessive, then it is called high blood pressure. In high blood pressure, there is more pressure on the walls of the arteries. It has four stages-

Mild hypertension140/90-159/99
Moderate hypertension160/110-179/109
severe hypertension180/110

Symptoms of High Blood Pressure

If you have high blood pressure, you will see its symptoms. These symptoms are as follows-

  • Formation of blood spots in the eyes- If your blood pressure has become high, then dust spots will start appearing in your eyes. It affects your eyesight. In high blood pressure, the blood vessels of the retina present in the back of the eye get damaged, which causes many problems.
  • Dizziness- Dizziness is a common symptom of high blood pressure. If you are experiencing excessive dizziness and headache, then your blood pressure is high.
  • Difficulty in breathing- Difficulty in breathing occurs in high blood pressure.
  • Chest pain.
  • Bleeding from the nose.
  • Skin redness.

High Blood Pressure Treatments

If you want to avoid high blood pressure, then you have to get it treated. Below are some tips to control high blood pressure-

  • If you are overweight then you have to balance your weight.
  • The best way to keep blood pressure balanced is to exercise. If you exercise regularly, your blood pressure will be balanced.
  • Control sugar, salt and fat intake and eat a healthy diet. Sugar causes high blood pressure.
  • Do not consume alcohol and smoking. Smoking weakens the arteries. Even if you take more medicines, your blood pressure can be high.
  • Do not consume coffee. Do not consume items that contain caffeine.
  • Do not consume such food, which requires more power to digest.

Cause of High Blood Pressure

Having high blood pressure increases the risk of heart attack. If a person’s BP has become high, then his heartbeat can also stop. The person may have dementia and the memory may be weak. Therefore, do not ignore high blood pressure and get treatment at the right time. There are many reasons for having high blood pressure. These reasons are given below-

  • Chronic kidney disease
  • Excessive salt and alcohol consumption
  • Genetics
  • Medical conditions such as sleep apnea
  • High or less physical activity
  • Obesity
  • Smoking
  • Stress

What is low blood pressure ?

Low blood pressure is also called hypotension. When the blood pressure falls below the normal range, it is called low blood pressure. Due to low blood pressure, blood cannot reach the heart, brain and other organs. Normal blood pressure should be less than 120/80 (systolic/diastolic). Less than 90 mm Hg for systolic and less than 60 mm Hg for diastolic is considered low BP.

Due to low BP, you can face many problems. Dizziness and fainting are both the main symptoms of low BP. When you stand up, you feel dizzy, it is a symptom of low BP. Low blood volume, heart disease and medications are symptoms of low BP. The risk of both low and high BP generally increases with age. The treatment of low BP depends on the cause of its occurrence.

Symptoms of low blood pressure

If your blood pressure becomes low then it will start affecting your body. Its main symptoms are given below-

Weakness and nutritional deficiency

Nutritional deficiency and weakness are an increased cause of low blood pressure. If there is a lack of nutrients in your body, then blood production stops. There is a shortage of red blood cells and blood pressure drops.

Heart disease

If there is any kind of problem related to the heart, then blood pressure can be low. If you have heart problem then you have to be more careful.


Sometimes the lack of blood in the body causes low blood pressure. Due to a major injury or internal bleeding, there is a loss of blood in the body, which leads to low blood pressure. There will be weakness in your body due to lack of blood.

Insufficiency of water

Water is the most essential element for our body. Lack of water causes weakness in the body. Lack of water not only causes low blood pressure but also other health problems. You have to face problems like vomiting, fever.


Low blood pressure can occur in women during pregnancy because the circulatory system grows rapidly at this time. During pregnancy, many glands work in the body.

Other symptoms

In general, low blood pressure can occur when you suddenly feel extremely weak or dizzy. Major symptoms of low blood pressure are fatigue, depression, nausea, thirst, blurred vision, pallor of the skin, coldness of the body, half-hearted and rapid breathing.

Even if you are suffering from any other disease and are taking medicines continuously, you will still have to face low blood pressure. If you have some other health-related problems like diabetes, thyroid, Addison’s disease etc., then you may be a patient of low blood pressure. Shock can also cause low blood pressure. If you are suddenly scared of something, then your blood pressure will be in law.

Low Blood Pressure Treatments

  • Consume green vegetables so that your body remains energetic. If your body remains weak then your BP will continue to be low.
  • Do not take excessive medicines.
  • Complete the lack of blood.
  • Drink plenty of water to avoid low blood pressure.

Blood pressure normal range

It is very important to have normal blood pressure. Otherwise your body may suffer from diseases. High blood pressure damages your heart and low blood pressure makes your body weak. Below you are given the range of normal blood pressure-

Blood Pressure FAQ

1. What is blood pressure?

Blood pressure is the force of blood against the walls of the arteries as the heart pumps it around the body. It is measured in millimeters of mercury (mmHg) and is represented by two numbers: systolic and diastolic.

2. What do the numbers in blood pressure readings mean?

The numbers in blood pressure readings represent the pressure in the arteries during two different phases of the heartbeat. The top number, or systolic pressure, measures the pressure when the heart contracts. The bottom number, or diastolic pressure, measures the pressure when the heart is at rest between beats.

3. What is considered normal blood pressure?

Normal blood pressure is generally considered to be around 120/80 mmHg. However, it is important to note that optimal blood pressure can vary depending on factors such as age, gender, and overall health.

4. What are the different categories of blood pressure?

Blood pressure readings are categorized as follows:

  • Normal: Less than 120/80 mmHg
  • Elevated: 120-129/less than 80 mmHg
  • Hypertension Stage 1: 130-139/80-89 mmHg
  • Hypertension Stage 2: 140 or higher/90 or higher mmHg
  • Hypertensive Crisis: Higher than 180/higher than 120 mmHg (Seek immediate medical attention)

5. What are the risk factors for high blood pressure?

Several factors can increase the risk of developing high blood pressure, including age, family history, obesity, lack of physical activity, smoking, excessive alcohol consumption, stress, and certain medical conditions.

6. How can I manage or prevent high blood pressure?

Managing or preventing high blood pressure involves adopting a healthy lifestyle. This includes maintaining a balanced diet low in sodium and high in fruits, vegetables, and whole grains, engaging in regular physical activity, quitting smoking, limiting alcohol consumption, managing stress, and maintaining a healthy weight.

7. Can high blood pressure be treated?

Yes, high blood pressure can be treated through lifestyle changes and, in some cases, medication. Lifestyle modifications may include dietary changes, regular exercise, weight loss, stress management, and reducing alcohol consumption. Medications may be prescribed by a healthcare professional to help lower blood pressure if lifestyle changes alone are not sufficient.

8. How often should blood pressure be checked?

It is recommended to have blood pressure checked at least once every two years for adults with normal blood pressure. Individuals with high blood pressure or other risk factors may need more frequent monitoring as advised by their healthcare provider.

9. Are there any symptoms of high blood pressure?

High blood pressure is often referred to as the “silent killer” because it usually does not cause noticeable symptoms. Regular blood pressure check-ups are essential to detect and manage high blood pressure effectively.
