Hypertension, also known as high blood pressure, is a serious medical condition that can lead to a variety of health problems if left untreated. It's a condition in which the force of blood against the walls of the arteries is persistently elevated.
Hypertension is a common condition, affecting an estimated one in three adults worldwide. It's a major risk factor for heart disease, stroke, kidney failure, and other serious health problems. The good news is that hypertension can be controlled with medication and lifestyle changes.
In this article, we'll discuss what hypertension is, what causes it, and how it's treated. We'll also provide tips for preventing hypertension and managing it if you have it.
what is hypertension
Hypertension is a condition in which blood pressure is persistently elevated.
- High blood pressure
- Major risk factor
- Heart disease
- Stroke
- Kidney failure
- Controllable with medication
- Lifestyle changes
Hypertension can be asymptomatic, so it's important to have your blood pressure checked regularly.
High blood pressure
High blood pressure, also known as hypertension, is a condition in which the force of blood against the walls of the arteries is persistently elevated. This can damage the blood vessels and lead to a variety of health problems, including heart disease, stroke, kidney failure, and vision loss.
Blood pressure is measured in millimeters of mercury (mm Hg). A blood pressure reading consists of two numbers: the systolic blood pressure and the diastolic blood pressure. Systolic blood pressure is the pressure when the heart beats and pumps blood out to the body. Diastolic blood pressure is the pressure when the heart rests between beats.
Normal blood pressure is less than 120/80 mm Hg. High blood pressure is defined as a systolic blood pressure of 130 mm Hg or higher, or a diastolic blood pressure of 80 mm Hg or higher.
Hypertension is often asymptomatic, which means that it can go undetected for years. This is why it's important to have your blood pressure checked regularly, especially if you have risk factors for hypertension, such as being overweight or obese, having a family history of hypertension, or being physically inactive.
If you have high blood pressure, your doctor will work with you to develop a treatment plan. This may include medication, lifestyle changes, or a combination of both.
Major risk factor
Hypertension is a major risk factor for a number of serious health problems, including:
- Heart disease: Hypertension can damage the blood vessels that supply blood to the heart, increasing the risk of heart attack and stroke.
- Stroke: Hypertension can also damage the blood vessels in the brain, increasing the risk of stroke.
- Kidney failure: Hypertension can damage the kidneys, leading to kidney failure.
- Vision loss: Hypertension can damage the blood vessels in the eyes, leading to vision loss.
- Dementia: Hypertension is a risk factor for dementia, including Alzheimer's disease.
The higher your blood pressure, the greater your risk of developing these health problems. Even a small increase in blood pressure can significantly increase your risk.
That's why it's important to have your blood pressure checked regularly and to take steps to lower your blood pressure if it's high. This may include making lifestyle changes, such as eating a healthy diet, getting regular exercise, and managing stress. If lifestyle changes aren't enough to lower your blood pressure, your doctor may prescribe medication.
By controlling your blood pressure, you can help reduce your risk of developing these serious health problems.
Heart disease
Hypertension is a major risk factor for heart disease, which is the leading cause of death worldwide.
- High blood pressure can damage the blood vessels that supply blood to the heart.
This can lead to a buildup of plaque, which is a combination of cholesterol, fat, calcium, and other substances. Plaque can narrow the arteries and make it harder for blood to flow to the heart. This can cause chest pain, shortness of breath, and other symptoms of heart disease.
- High blood pressure can also weaken the heart muscle.
This can lead to heart failure, which is a condition in which the heart is unable to pump enough blood to meet the body's needs. Heart failure can cause shortness of breath, fatigue, and swelling in the feet and ankles.
- High blood pressure can also lead to an aneurysm.
An aneurysm is a bulge in a blood vessel. If an aneurysm ruptures, it can cause life-threatening bleeding.
- High blood pressure can also increase the risk of sudden cardiac death.
Sudden cardiac death is a condition in which the heart suddenly stops beating. It is often caused by an electrical problem in the heart.
By controlling your blood pressure, you can help reduce your risk of developing heart disease and its complications.
Stroke
Hypertension is a major risk factor for stroke, which is the fifth leading cause of death worldwide.
- High blood pressure can damage the blood vessels in the brain.
This can lead to a buildup of plaque, which is a combination of cholesterol, fat, calcium, and other substances. Plaque can narrow the arteries and make it harder for blood to flow to the brain. This can cause a stroke.
- High blood pressure can also weaken the blood vessels in the brain.
This can lead to a rupture, which is a burst blood vessel. A rupture can cause a hemorrhagic stroke.
- High blood pressure can also lead to a transient ischemic attack (TIA).
A TIA is a temporary interruption of blood flow to the brain. TIAs are often called "mini-strokes" because they have similar symptoms to strokes, such as numbness or weakness on one side of the body, difficulty speaking, and vision problems. TIAs are a warning sign that you are at high risk for a stroke.
- High blood pressure can also increase the risk of stroke complications.
These complications can include difficulty speaking, swallowing, and moving. They can also lead to long-term disability or death.
By controlling your blood pressure, you can help reduce your risk of stroke and its complications.
Kidney failure
Hypertension is a major risk factor for kidney failure, which is a condition in which the kidneys are unable to filter waste products and excess fluid from the blood. This can lead to a buildup of toxins in the blood and a decrease in the production of urine.
High blood pressure can damage the blood vessels in the kidneys, which can lead to scarring and a decrease in kidney function. This can also lead to a buildup of fluid in the body, which can cause swelling in the feet, ankles, and hands. Hypertension can also increase the risk of developing kidney stones and urinary tract infections.
In the early stages of kidney failure, there may be no symptoms. As the condition progresses, symptoms may include:
- Nausea and vomiting
- Loss of appetite
- Fatigue
- Weakness
- Muscle cramps
- Headaches
- Itching
- Difficulty sleeping
- Decreased urine output
- Swelling in the feet, ankles, and hands
If kidney failure is not treated, it can lead to a number of serious health problems, including heart disease, stroke, and death.
By controlling your blood pressure, you can help reduce your risk of developing kidney failure and its complications.
Controllable with medication
Hypertension is a controllable condition. There are a number of medications that can be used to lower blood pressure. These medications work in different ways to relax the blood vessels, reduce fluid retention, or decrease the heart rate.
The type of medication that is best for you will depend on your individual needs. Your doctor will consider your age, overall health, and other medications you are taking when prescribing a blood pressure medication.
Some of the most common types of blood pressure medications include:
- ACE inhibitors: ACE inhibitors work by relaxing the blood vessels.
- Angiotensin II receptor blockers (ARBs): ARBs also work by relaxing the blood vessels.
- Beta-blockers: Beta-blockers slow the heart rate and reduce the force of heartbeats.
- Diuretics: Diuretics help the body get rid of excess fluid and sodium.
- Calcium channel blockers: Calcium channel blockers relax the blood vessels and reduce the heart rate.
It is important to take your blood pressure medication exactly as prescribed by your doctor. Even if you feel fine, it is important to continue taking your medication to keep your blood pressure under control.
By taking your medication and making other lifestyle changes, you can control your hypertension and reduce your risk of developing serious health problems.
Lifestyle changes
In addition to taking medication, there are a number of lifestyle changes you can make to help lower your blood pressure and improve your overall health.
Some of the most important lifestyle changes include:
- Eat a healthy diet: A healthy diet for hypertension includes plenty of fruits, vegetables, and whole grains. It also includes lean protein and low-fat dairy products. Limit your intake of saturated fat, cholesterol, and sodium.
- Get regular exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Exercise helps to lower blood pressure and improve overall cardiovascular health.
- Maintain a healthy weight: If you are overweight or obese, losing weight can help to lower your blood pressure.
- Reduce sodium intake: Too much sodium in your diet can raise blood pressure. Aim to consume no more than 2,300 milligrams of sodium per day.
- Limit alcohol consumption: Drinking too much alcohol can raise blood pressure. Men should limit their alcohol intake to two drinks per day, and women should limit their intake to one drink per day.
- Quit smoking: Smoking is a major risk factor for heart disease and stroke. Quitting smoking can help to lower your blood pressure and improve your overall health.
- Manage stress: Stress can raise blood pressure. Find healthy ways to manage stress, such as exercise, yoga, or meditation.
By making these lifestyle changes, you can help to lower your blood pressure and reduce your risk of developing serious health problems.
