Difference between systolic and diastolic pressure

When the heart beats, blood reaches the whole body through the arteries, but the heartbeat does not remain the same throughout the day. It keeps on changing with different activities of the body. To check this, systolic and diastolic pressure are detected. Systolic and diastolic blood pressure is essential for health. If the reading is high, then it is linked to high blood pressure. On the other hand, if it is less, it means that not enough blood is reaching the brain and other organs. This condition is called low blood pressure. Changes in systolic and diastolic blood pressure also indicate heart disease and other physical problems.

When the heart beats, it pumps blood into the arteries. Systolic measures the pressure of the blood present in the arteries. During this, the blood pressure is highest. When a person is resting and the systolic pressure reading is less than 120 mmHg, it is considered normal. On the other hand, if it is less than 90 mmHg, then it can be a matter of concern. In this situation, proper treatment is required. On the other hand, if the reading is more than 180 mmHg, it is considered to be the most dangerous form of high BP.

It is also important to understand here that if a person exercises or runs, then the heart beats faster and pumps blood faster, due to which the systolic pressure increases. Therefore, blood pressure should always be checked at rest. If still the systolic pressure is increased, then the main reason behind this is believed to be a hardening of the arteries. When the arteries harden, the heart has to work harder to pump blood.

Several stages of high systolic have also been considered, which are as follows -

• If the systolic pressure is between 130-139, then it is considered stage 1 high BP, which can be cured by taking medicines and lifestyle changes for some time on the advice of the doctor.
• 140 or more is considered stage 2 high BP, in which there is a risk of stroke or heart attack. In this situation, there may be a need to take medicine for a long time.
• A Systolic of 180 or more is considered a severe form of high BP and in this condition, the patient needs immediate treatment.

When the reading is less than 90 mmHg, it is called low BP. This can cause conditions like vertigo, dizziness, or fainting. If low BP is not treated, the kidney of the patient may stop working.

The condition of low systolic blood pressure is formed when the amount of blood in the body becomes very less. This happens due to a lack of water in the body or excessive bleeding. In addition, when the heart muscles are unable to pump blood, the systolic pressure may also decrease. This is due to damage to the heart muscle (cardiomyopathy) or sudden widening of the arteries.

Normal diastolic blood pressure is less than 80 mmHg. If someone has high BP, then the diastolic number is seen to be increased even during rest. If the diastolic blood pressure is 60 mmHg or less, it is classified as severely low and if it is 110 mmHg or more, it is classified as severely high.

There are many stages of high diastolic blood pressure -

• A Diastolic BP of 80-89 is stage 1 hypertension, which can be normalized by taking medicines and lifestyle changes for some time on the advice of the doctor.
• A diastolic BP of 90 or more is stage 2 hypertension, which can significantly increase the risk of stroke or heart attack. In this situation, there is a need to take medicine for a long time.
• Diastolic BP of 120 or more means high BP is at a dangerous level and the patient needs immediate treatment.

The level of blood pressure keeps on changing throughout the day. Where it is highest in the morning, then it is less in the night. Therefore, if someone is a victim of high BP, then he should check his BP daily at a fixed time. It is better to check it in the morning before breakfast or before dinner in the evening and once you have decided when to check it, note the BP at the same time every day. Doing this gives the most accurate results.

Blood pressure is a measure of the pressure exerted on the arteries when the heart beats (systolic) and when the heart relaxes (diastolic) between beats. It is necessary to know the systolic and diastolic numbers to check and treat high BP and low BP. Therefore, if someone feels that his blood pressure is not right, then he should sit comfortably in a place and check his BP calmly.
