Blood pressure is defined as the pressure exerted by a blood column against the walls of the arteries. It is often described in two values. The upper value is the systolic pressure and the lower value is the diastolic blood pressure.
Blood pressure of 110/70 mmHg is normal in an adult. According to the latest American Heart Association guidelines, all people with blood pressure greater than 130/80 mmHg have hypertension and need treatment. Thus, the systolic blood pressure of 110 to 130 mmHg is acceptable and 60 to 70 diastolic blood pressure is acceptable. Anything lower is low blood pressure.
Hypertension, sometimes referred to as high blood pressure (high BP), is a medical disorder in which the blood pressure in the arteries remains consistently high. It is a leading cause of death in developing countries.
Cardiovascular illness, stroke, heart attack, heart failure, aneurysm, atrial fibrillation, peripheral arterial disease, vision loss, chronic renal disease, and dementia are all risks associated with hypertension.
What are the causes of hypertension?
Hypertension is divided into two categories, each with its own set of causes.
- Hypertension (primary or essential)
- There is no known cause of hypertension in most people. Primary or essential hypertension is a type of hypertension that develops gradually over time.
- Multiple variables can cause primary hypertension, including:
- Hypertension secondary to primary hypertension
- An underlying health problem can induce hypertension in some people.
- Secondary hypertension is a type of high blood pressure that appears suddenly. Measured blood pressure is greater in secondary hypertension than in initial hypertension.
- Secondary hypertension is caused by a variety of conditions and their consequences, including:
- Kidney disease
- Congenital heart defects
- Congenital blood vessel defects
- Obstructive sleep apnea
- Endocrine tumors
- Adrenal gland tumors
- Cushing syndrome
- Congenital adrenal hyperplasia
- Thyroid problems
- Use of illegal substances such as cocaine and amphetamines
- Pregnancy
- Obesity
- Certain medications, such as birth control pills, cold remedies, decongestants, pain relievers, and some prescription pharmaceuticals
13 risk factors of hypertension
Hypertension is caused by several factors, including:
- Age older than 60 years (With age, plaque forms and causes the arteries to harden and constrict)
- Being overweight or obese
- Regular tobacco use
- Alcohol abuse
- Male gender
- Sedentary lifestyle
- Lack of exercise
- High-fat diet
- High salt intake in the diet
- Low potassium intake diet
- Stress
- Family history of hypertension
- Existing health conditions, such as cardiovascular disease, diabetes, chronic kidney disease, sleep apnea, and high cholesterol levels

Hypertension is often referred to as a "silent killer," because most people with it have no symptoms. It may take many years for symptoms to appear when the problem has progressed to a severe level.
Nonetheless, symptoms of hypertension may include:
- Nosebleeds
- Anxiety
- Sweating
- Fatigue or confusion
- Irregular heartbeat
- Facial flushing
- Dizziness
- Vision problems
- Chest pain
- Shortness of breath
- Sleeping issues
- Blood in the urine
- Blood spots in the eyes
- Chest, neck, or ear pounding
What is the treatment for hypertension?
Treatment for high blood pressure is aimed to keep blood pressure below 130/80 mmHg.
Treatment involves healthy lifestyle modifications (weight management, salt restriction, regular physical activity, dietary recommendations) and medications.
- The type of medication prescribed for high blood pressure is determined by the patient's blood pressure readings and overall health.
- Diuretics, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, calcium channel blockers, beta-blockers, alpha-blockers, alpha-beta blockers, aldosterone antagonists, vasodilators, and central-acting medicines are some of the medications used to treat hypertension.

What are the complications of hypertension?
Hypertension damages blood arteries and organs by putting too much pressure on artery walls.
Uncontrolled high blood pressure can lead to a variety of complications, including:
- Heart attack or stroke: High blood pressure can cause the arteries to stiffen and thicken, resulting in a heart attack or stroke.
- Heart failure: Due to the high pressure in the blood vessels, the heart needs to work harder to pump blood. The walls of the heart's pumping chamber swell because of this (left ventricular hypertrophy), which can lead to heart failure.
- Aneurysm: An abnormal bulge in a blood vessel that can cause death if it bursts.
- Kidney failure: Kidneys with weakened and restricted blood arteries are unable to operate normally.
- Blindness: Hypertensive retinopathies in the eye can cause vision loss.
- Metabolic syndrome: Metabolic syndrome is a collection of metabolic illnesses. Diabetes, heart disease, and stroke are more likely to occur as a result of these disorders.
- Memory or comprehension problems: Uncontrolled hypertension impairs a person's capacity to think, recall and acquire or comprehend new concepts.
- Dementia: Blood flow to the brain is restricted by narrowed or clogged arteries, resulting in dementia.
Can I Check My Blood Pressure With My Phone?

It is possible but not reliable. Hence, it is not advised.
You cannot accurately check your blood pressure with your phone. Several apps, both Android and iOS, claim that they can measure your blood pressure via new technology. None of these apps have any backing from health experts and scientists as far as their efficiency or credibility is concerned. Thus, it is better to rely on the standard blood pressure equipment called a sphygmomanometer for accurately measuring the blood pressure. You may use the apps on your phone for
- Keeping a record of your blood pressure readings by manually entering the data.
- Sending your blood pressure readings to your doctor’s phone and receiving your doctor’s feedback.
- Keeping a track of your salt intake.
- Getting reminders for staying active, exercising and drinking water.
- Ensuring adherence to medications.

Blood Pressure Readings: Chart, Normal, High, Low
Blood pressure is the force applied by the blood over the inner walls of the arteries. Although the average blood pressure for a person remains constant, it shows minor fluctuations throughout the day—declining while relaxing and momentarily increasing while being excited or under stress. An increase in resting blood pressure can scar, stiffen, or harden the arteries.What Are Normal Blood Pressure Ranges by Age For Men and Women?
What is normal, low and high blood pressure? Find charts of blood pressure readings and ranges for men and women of different ages. Discover what causes high and low blood pressure and how to prevent it.High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. 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.

Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, and fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.Low Blood Pressure (Hypotension) Causes
Low blood pressure (hypotension) occurs when blood pressure drops below the normal range. Low blood pressure can be temporary, or it can be a chronic (long-lasting) condition.Low Blood Pressure
