High Blood Pressure: Causes, Symptoms & Treatment – FFD

Blood Pressure—Everyone Has It!

Every living person has blood pressure. Blood Pressure (BP) refers to the force with which blood is pumped by the heart through the circulatory system. This is a normal and essential body function. Problems arise only when this pressure becomes consistently high.

This usually happens when cholesterol plaques start building up on artery walls, narrowing them and increasing resistance to blood flow, which ultimately raises blood pressure. Since the heart works through a rhythmic process of contraction and relaxation, BP is measured at two different phases.

This is why blood pressure is shown as two numbers, such as 120/80. The unit of measurement is mmHg (millimeters of mercury). The upper value, known as systolic pressure, indicates pressure in the arteries when the heart beats, while the lower value, known as diastolic pressure, represents the pressure between heartbeats.

Causes of High Blood Pressure

High blood pressure is generally categorized into primary (essential) hypertension and secondary hypertension.

Primary High Blood Pressure

Primary hypertension is not caused by any specific underlying disease. It usually develops due to lifestyle-related factors such as unhealthy diet, lack of physical activity, stress, genetic influence, and several other contributing factors.

It is more commonly seen in older adults, especially people above 60 years of age. Other major contributing factors include diabetes, excessive salt intake, high caffeine consumption, being overweight or obese, alcohol misuse, sedentary lifestyle, lack of proper sleep, and hereditary predisposition.

Primary high blood pressure can often be improved or reversed by correcting unhealthy lifestyle habits.

Secondary High Blood Pressure

Secondary hypertension occurs due to an identifiable medical condition or the use of certain medications.

It may be caused by disorders related to the adrenal glands, kidney diseases, obstructive sleep apnea, preeclampsia, or the use of medications such as NSAIDs (non-steroidal anti-inflammatory drugs), which are commonly used for pain, inflammation, and fever.

Symptoms of High Blood Pressure

Hypertension often shows no clear symptoms in the early stages, which is why it is called a “silent killer.” Regular monitoring is important, especially for adults above 40 years of age, while younger individuals between 18 and 39 should also check their BP at least once a year.

Multiple readings are usually recommended to avoid temporary fluctuations such as white coat syndrome, where blood pressure rises due to anxiety during medical visits.

As the condition progresses and begins to affect organs, symptoms may include blood in urine (hematuria), blurred vision, nosebleeds, chest pain or shortness of breath, severe headaches, dizziness, persistent fatigue, and confusion-like states.

Treatment of High Blood Pressure

Lifestyle-Based Treatment

Managing primary hypertension largely depends on lifestyle improvements. A healthy diet with reduced salt, fat, and animal-based products while increasing intake of fruits, vegetables, nuts, and legumes is recommended. Moderate alcohol consumption is also advised.

Regular physical activity of 45 minutes to one hour daily, including cardio, strength training, and flexibility exercises, plays a key role in controlling blood pressure. Stress management techniques such as meditation and relaxation practices are also beneficial. Avoiding tobacco use and ensuring 7–8 hours of quality sleep every night are equally important.

Medications

When necessary, doctors may prescribe medications to help control blood pressure. These include beta-blockers, which reduce heart rate and cardiac output; vasodilators, which relax blood vessels; calcium channel blockers, which reduce calcium entry into blood vessels and help muscles relax; ACE inhibitors, which lower production of angiotensin; ARBs, which prevent blood vessel narrowing; and diuretics, which help remove excess water and sodium from the body.

Complications of High Blood Pressure

If left untreated, high blood pressure can lead to serious health complications due to artery narrowing caused by plaque buildup. This forces the heart to work harder and may result in aneurysms, heart attacks, kidney failure, stroke, and hypertensive retinopathy, which can even lead to vision loss.

Who is at Risk?

Individuals above 60 years of age are at higher risk due to natural stiffening of arteries. Excess body weight significantly increases risk. Regular consumption of tobacco and alcohol also contributes to hypertension. People with underlying conditions such as diabetes, kidney disease, heart disease, and high cholesterol are more vulnerable. Certain ethnic groups may also have a higher predisposition to developing high blood pressure.

FAQ’s

What are the main causes of high blood pressure?

High blood pressure is mainly caused by unhealthy lifestyle habits such as poor diet, lack of exercise, smoking, alcohol consumption, chronic stress, obesity, genetic factors, aging, and underlying conditions like diabetes or kidney disease.

What are the common symptoms of high blood pressure?

In most cases, high blood pressure shows no symptoms. In severe conditions, symptoms may include headaches, dizziness, chest pain, shortness of breath, and blurred vision. If untreated, it can lead to serious complications like stroke or heart attack.

What treatments are available for managing high blood pressure?

Management includes lifestyle changes such as a healthy diet, regular exercise, weight control, stress management, and proper sleep. In some cases, medications like diuretics, beta-blockers, ACE inhibitors, and calcium channel blockers are prescribed. Functional approaches like plant-based diets and holistic lifestyle modifications also help improve control.
