High blood pressure, also known as hypertension, is a medical condition in which the force of blood against the walls of arteries is consistently too high. Blood pressure is measured in two numbers, with the top number (systolic pressure) representing the pressure when the heart beats and the bottom number (diastolic pressure) representing the pressure when the heart is at rest between beats. Normal blood pressure is typically around 120/80 mm Hg.
When blood pressure consistently measures at or above 130/80 mm Hg, it is considered high blood pressure. There are two main types of hypertension: primary (essential) hypertension and secondary hypertension.
Primary hypertension, which is the most common form, develops gradually over time with no identifiable cause. Secondary hypertension, on the other hand, is caused by an underlying condition such as kidney disease, sleep apnea, or hormonal imbalances.
High blood pressure is often referred to as a “silent killer” because it often has no symptoms but can cause serious damage to the heart, blood vessels, and other organs over time. It is a major risk factor for heart disease, stroke, and kidney disease. Treatment may involve lifestyle changes such as diet and exercise, as well as medications to lower blood pressure.

The diagnosis of high blood pressure, also known as hypertension, is typically made through a series of blood pressure readings taken over time. A healthcare provider will use a blood pressure cuff and stethoscope or an automated blood pressure machine to measure a patient’s blood pressure in both the sitting and standing positions.
If the readings consistently measure at or above 130/80 mm Hg, a diagnosis of hypertension may be made. In some cases, additional testing may be needed to determine if there is an underlying cause for the high blood pressure, such as kidney disease or hormonal imbalances.
Blood pressure readings may be taken at home or in a healthcare provider’s office, and it is important to follow any instructions given for preparing for the test, such as avoiding caffeine or certain medications beforehand.
Regular blood pressure screenings are recommended for all adults, as hypertension can be asymptomatic but can cause serious health problems over time if left untreated. Treatment may involve lifestyle changes, such as diet and exercise, as well as medications to lower blood pressure.
Making lifestyle changes can help improve high blood pressure, either alone or in combination with medication. Here are some lifestyle changes you can take to improve your high blood pressure:
- Eating a healthy diet: A diet rich in fruits, vegetables, whole grains, lean protein, and low-fat dairy can help lower blood pressure. It’s also important to limit sodium intake, processed foods, and unhealthy fats.
- Maintaining a healthy weight: Being overweight or obese can increase blood pressure, so maintaining a healthy weight through a healthy diet and regular exercise can help lower blood pressure.
- Engaging in regular exercise: Physical activity can help lower blood pressure, so aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Limiting alcohol intake: Drinking too much alcohol can raise blood pressure, so it’s important to limit alcohol intake to no more than one drink per day for women and two drinks per day for men.
- Quitting smoking: Smoking can damage blood vessels and increase blood pressure, so quitting smoking is crucial for improving high blood pressure.
- Managing stress: Chronic stress can increase blood pressure, so finding ways to manage stress, such as through meditation, yoga, or deep breathing exercises, can help lower blood pressure.
Making these lifestyle changes may not only help lower blood pressure but also improve overall health and reduce the risk of other health problems. However, it’s important to work with a healthcare provider to determine the most appropriate treatment plan for you, based on your individual needs and medical history.
There are many risk factors that can increase the likelihood of developing high blood pressure, also known as hypertension. Some of these risk factors can be controlled through lifestyle changes, while others are out of our control. The following are some of the most common risk factors for high blood pressure:
- Age: As we age, our risk of developing high blood pressure increases.
- Family history: Hypertension tends to run in families, so if your parents or other close relatives have high blood pressure, you may be at increased risk.
- Obesity or being overweight: Excess weight puts additional strain on the heart and blood vessels, increasing the risk of hypertension.
- Physical inactivity: A sedentary lifestyle can contribute to high blood pressure.
- Unhealthy diet: A diet high in sodium, saturated fats, and processed foods can increase the risk of hypertension.
- Smoking: Nicotine and other chemicals in tobacco smoke can damage blood vessels and increase blood pressure.
- Stress: Chronic stress can contribute to hypertension.
- Certain medical conditions: Medical conditions such as kidney disease, diabetes, and sleep apnea can increase the risk of hypertension.
- Medications: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), decongestants, and some antidepressants, can increase blood pressure.
By controlling modifiable risk factors, such as maintaining a healthy weight, engaging in regular physical activity, and following a healthy diet, you can help lower your risk of developing high blood pressure.
Signs and Symptoms
High blood pressure, also known as hypertension, often has no symptoms in its early stages. This is why it is often referred to as a “silent killer,” as it can go undetected for years and cause damage to the heart, blood vessels, and other organs without a person knowing it. However, as the condition progresses, some people may experience symptoms such as:
- Headaches: While headaches are a common symptom of many health conditions, some people with hypertension may experience headaches, particularly in the back of the head and neck.
- Dizziness: High blood pressure can cause dizziness, especially when standing up suddenly.
- Shortness of breath: Hypertension can make it more difficult to breathe, particularly during physical activity.
- Chest pain: High blood pressure can contribute to chest pain or discomfort, particularly during physical activity or when experiencing emotional stress.
- Vision changes: High blood pressure can cause vision changes or even vision loss in rare cases.
Many people with high blood pressure have no symptoms at all, which is why regular blood pressure screenings are recommended for all adults.
The treatment for high blood pressure, also known as hypertension, typically involves a combination of lifestyle changes and medications. The primary goal of treatment is to lower blood pressure to a healthy range and reduce the risk of complications such as heart disease, stroke, and kidney disease.
To achieve this goal, it is recommended to adopt a healthy lifestyle, such as following a healthy diet, maintaining a healthy weight, engaging in regular exercise, limiting alcohol intake, and managing stress. These lifestyle changes not only help lower blood pressure but also improve overall health and reduce the risk of other health problems.
If lifestyle changes alone are not effective in lowering blood pressure, medications may be prescribed. Medications that can be used to lower blood pressure include diuretics, ACE inhibitors, calcium channel blockers, beta-blockers, and angiotensin receptor blockers. However, working closely with a healthcare provider is essential to determine the most appropriate treatment plan based on individual needs and medical history.
Regular blood pressure monitoring is also crucial to ensure that treatment is effective. With proper treatment and management, high blood pressure can be controlled, and the risk of complications can be reduced. Therefore, taking action to manage high blood pressure is important for maintaining good health and preventing serious health problems.
Who is affected?
High blood pressure, also known as hypertension, can affect anyone regardless of age, gender, or race. However, certain factors can increase the risk of developing high blood pressure, such as:
- Age: As people age, the risk of developing high blood pressure increases.
- Family history: Having a family history of high blood pressure can increase the risk of developing the condition.
- Obesity or being overweight: Being overweight or obese can increase the risk of developing high blood pressure.
- Lack of physical activity: Leading a sedentary lifestyle can increase the risk of developing high blood pressure.
- Poor diet: A diet high in sodium, unhealthy fats, and processed foods can increase the risk of developing high blood pressure.
- Smoking: Smoking can damage blood vessels and increase the risk of developing high blood pressure.
- Chronic conditions: Certain chronic conditions such as diabetes, kidney disease, and sleep apnea can increase the risk of developing high blood pressure.
While anyone can develop high blood pressure, making lifestyle changes and managing chronic conditions can help reduce the risk of developing the condition or manage existing high blood pressure. Regular blood pressure monitoring is also important to catch and address any potential issues early on.
