- How Does It Affect?
High blood pressure or hypertension affects around 80 million Americans. Hypertension is also known as “the silent killer” because it often goes unnoticed and may cause serious complications such as kidney diseases, heart diseases, heart failure, and stroke. As many as 16 million Americans are unaware of the condition. High blood pressure occurs due to the tightening or stiffness of very small arteries called arterioles. As a result, the heart pumps harder through the stiff or narrow arterioles, leading to elevated pressure inside the vessels. High blood pressure or hypertension is when the blood pressure readings consistently range from 140 or higher for systolic or 90 or higher for diastolic. Blood pressure readings above 180/120 mmHg are dangerously high and require immediate medical attention.
What are the different types of blood pressure?
There are two main types of high blood pressure: primary and secondary high blood pressure.
- Primary high blood pressure: Also known as essential high blood pressure, this is the most common type of high blood pressure. Primary high blood pressure does not happen as a result of some underlying medical condition. This type of blood pressure develops over time as one gets older.
- Secondary high blood pressure: It is caused by another medical condition or due to the use of certain medications. It gets better once the condition is treated or when the medication is stopped.
Who is at risk of high blood pressure?
People associated with the following risk factors are more likely to get high blood pressure:
- Family history of high blood pressure
- African-American race
- Male gender
- Women aged above 55 years
- Consumption of a fat-rich and sodium-rich diet
- Tobacco use
- Oral contraceptive use
- Heavy alcohol drinking
- Physical inactivity
- Tumors in adrenal or pituitary glands
- Production of excess growth hormone
- Problems with parathyroid gland
- Reactions to medicines for other medical problems
How does high blood pressure affect the body?
High blood pressure affects the body in the following ways:
- It hardens the arteries because the excess pressure in the arteries causes the muscles lining the walls of the artery to thicken, leading to the narrowing of the passage.
- It increases the workload of the heart causing the heart to enlarge. The bigger heart demands more oxygen-rich blood but is unable to obtain it. As a result, the person may feel weak and tired.
- It damages the kidney as the blood supply gets affected due to prolonged high blood pressure.
- It affects the retina of the eye by causing the tiny blood vessels (capillaries) to bleed.
What are the symptoms of high blood pressure?
Most of the time, people do not experience any symptoms at all. In some cases, people with high blood pressure experience the following symptoms:

Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.
