Systole vs Diastole: Blood pressure is a measurement of the force of blood against the artery walls of the vascular system. The heart pushes blood into arteries, which transport it throughout the body. Hypertension is threatening because it causes the heart to pump blood faster out to the body and makes a significant contribution to coronary artery disease, brain hemorrhage, renal failure, and cardiac arrest.
Systole vs Diastole:
When we breathe we take in air and when we breathe out we exhale. That is the life cycle of humans. But the opposite is also true: When the human body stops breathing, it enters into a state called “diastole”. In this state, our circulatory system slows down to a point where it ceases all functions while our brain and nervous system are working normally.
In other words, during a person’s diastole there is no room for the heart to pump blood into our body. Other organs such as the brain and lungs can function normally. During this phase, breathing also becomes shallow and even audible sounds may be heard from a person’s nose or mouth as air is forced against it.
What Is “Normal” Blood Pressure?
The following is an example of a blood pressure reading: 120/80. It’s pronounced, “120 over 80.” The upper case is known as the systolic, and the bottom number is known as the diastolic. The ranges are as follows:
Normal: (120/80) is considered normal blood pressure
Elevated: Higher than 120 and less than 80 is called elevated 120-129/less than 80
Stage 1: Blood pressure within the range of 130-139/80-89 is the first stage of high blood pressure
Stage 2 : Blood pressure within the range of 140 and above/90 and above is stage 2nd blood pressure
Hypertension crisis: blood pressure greater than 180/less than 120 mmHg — Consult a doctor as soon as possible.
What causes high blood pressure?
The accurate reasons for hypertension are unknown, but several factors may be involved, including:
• Obesity or overweight
• insufficient physical activity
• Excessive salt in the diet
• advancing years
• Genetic factors
• Thyroid and adrenal dysfunction
The root cause of high blood pressure cannot be identified in up to 95 percent of cases in the United States.
Though the cause of essential hypertension is unknown, it has been connected to certain adverse outcomes. Hypertension runs in families and is much more common in men than in women. Race and age also are factors that affect hypertension. Blacks are significantly more likely than whites in the U.s to have hypertension,
Lifestyle and diet also have a significant impact on essential hypertension. The connection between sodium and hypertension is particularly compelling.
Most people with hypertension are “saline sensitive,” which means that anything more than their body’s minimum salt requirement is too much for them and raises their blood pressure. Overweight, diabetes, tension, inadequate calcium, potassium, and magnesium intake, lack of exercise, and prolonged alcohol consumption are all major risk factors for essential hypertension.

Secondary hypertension occurs when a prime cause of hypertension could be identified. Cancers or other malformations that cause the adrenal glands to produce excessive amounts of the hormones that raise blood pressure can also cause hypertension. Contraceptive pills, particularly childbirth, as well as medications that constrain blood vessels, all can increase blood pressure.
