Spotlight On Aging: High Blood Pressure
Changes due to aging may contribute to high blood pressure with no known cause . As people age, large arteries gradually stiffen and small arteries may become partially blocked. Some experts think that this stiffening combined with the narrowing of small arteries may partly explain why blood pressure increases as people age.
When blood pressure is checked, two values are recorded. The higher value reflects the highest pressure in the arteries, which is reached when the heart contracts . The lower value reflects the lowest pressure in the arteries, which is reached just before the heart begins to contract again . Blood pressure is written as systolic pressure/diastolic pressurefor example, 120/80 mm Hg . This reading is referred to as “120 over 80.”
You Shouldn’t Ignore White Coat Hypertension
Some people experience white coat hypertension, when blood pressure is elevated in the doctor’s office but not in other settings. These patients need to monitor their blood pressure at home or wear an ambulatory blood pressure monitor that takes your blood pressure every 30 minutes for 24 hours.
While white coat hypertension was formerly considered simple nervousness, recent research suggests otherwise.
A study published in the journal Hypertension found that people with white coat hypertension are at a significantly greater risk for developing sustained high blood pressure than people who have normal blood pressure. One possible explanation is that people with white coat hypertension have a harder time managing stress and anxiety.
Heart Attack And Heart Disease
High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause:
- Chest pain, also called angina.
- Heart attack, which happens when the blood supply to your heart is blocked and heart muscle begins to die without enough oxygen. The longer the blood flow is blocked, the greater the damage to the heart.
- Heart failure, a condition that means your heart cant pump enough blood and oxygen to your other organs.

Classification Of Blood Pressure
Blood pressure in adults is classified as normal, elevated blood pressure, stage 1 hypertension, or stage 2 hypertension.
However, the higher the blood pressure, the greater the risk of complicationseven within the normal blood pressure rangeso these limits are somewhat arbitrary.
A hypertensive urgency is diastolic blood pressure that is more than 120 mm Hg but has not yet caused any organ damage that is apparent to people or their doctors. A hypertensive urgency usually does not cause symptoms.
A hypertensive emergency is a particularly severe form of high blood pressure. Diastolic blood pressure is at least 120 mm Hg, and there is evidence of progressive damage in one or more vital organs , often accompanied by a variety of symptoms. Hypertensive emergencies are uncommon, but they are several times more common among Black people than among White people, among men than among women, and among people in lower socioeconomic groups than among those in higher socioeconomic groups. If untreated, a hypertensive emergency can be fatal.
Common Causes Of High Blood Pressure Spikes
Some people with high blood pressure will experience sharp rises in their blood pressure. These spikes, which typically last only a short period of time, are also known as sudden high blood pressure. These are some possible causes:
- Certain medications or combinations of medications
- Chronic kidney disease

What Is The White Coat Effect
White Coat Effect or White Coat Syndrome occurs when you worry about a doctors appointment or you are seated at a clinic waiting for your turn to visit the doctor and this causes a temporary spike in your blood pressure.
It gets its name from the white coats that doctors and medical staff wear in a professional setting. The white coat effect is worth monitoring but it may not always be a sign of a bigger health issue.

Excessive Salt Raises Blood Pressure
Too much sodium can cause water retention that puts increased pressure on your heart and blood vessels. People with high blood pressure and those at a high risk for developing hypertension, including adults over 50 and black men and women, should have no more than 1,500 milligrams of sodium daily of salt.
Even people with normal levels should eat salt in moderation. Stick to no more than 2,300 mg of sodium , per day.
Most dietary sodium comes from processed foods. Rules of thumb are to choose foods with 5% or less of the daily value of sodium per serving and opt for fresh poultry, fish and lean meats, rather than canned, smoked or processed. Similarly, fresh or frozen vegetables are better than canned.
A study published in the New England Journal of Medicine found that if people cut just 1/2 teaspoon of salt per day, it could help lower the number of new cases of heart disease per year by up to 120,000.
Further, potassium found in foods like sweet potatoes, spinach, bananas, oranges, low-fat milk and halibut can counterbalance the pressure-increasing effects of sodium by helping to rid the body of excess sodium.
Regular Blood Pressure Checks For Over Over 40’s
The only way to find out whether you have high blood pressure is to have your blood pressure checked regularly. Ask your GP when you are next due for yours to be checked.
Blood pressure checks are usually available on request at most GP surgeries and health clinics. Some surgeries have home monitoring devices available, which you may be able to use at the time of blood pressure medication start up or change. Many also have a policy of arranging regular checks for you.
Adults who are over 40 and have not been diagnosed with high blood pressure should have their blood pressure checked at least once every five years. However, your blood pressure should ideally be checked more frequently, particularly if you have any contributory risk factors.

Understanding High Blood Pressure In India Why Is It A Warning Sign
What is blood pressure? It refers to the force exerted by the blood against the artery walls when the heart pumps blood. When the force is too high, it starts affecting the body. Knowing the causes of high blood pressure will help in maintaining the blood pressure at normal levels and leading a healthy life.
Understanding BP readings – How is high BP diagnosed?
Blood pressure readings consist of two values systolic blood pressure and diastolic blood pressure.
Systolic blood pressure This is the first value, it is the measure of pressure within your arteries when your heartbeats.
Diastolic blood pressure This is the second value, it is the measure of pressure within the arteries when your heart rests between beats.
Normal BP120 mmHg/80 mmHg or less than that
- Elevated BPThe systolic values are between 120 and 129 mmHg and the diastolic values are less than 80 mmHg.
- High BP The systolic values fall in the range 130 139 mmHg or the diastolic values fall in the range 80 89 mmHg.
- High BP The systolic values are 140 mmHg or higher or the diastolic values 90 mmHg or higher.
- Hypertensive crisisThe systolic values are higher than 180 and/or the diastolic higher than 120 mmHg.
A constant high blood pressure reading in most cases may indicate a severe underlying issue that needs to be identified to prevent further heart-related complications. In case of a hypertensive crisis, you should seek medical help immediately.

What If Lifestyle Changes Dont Help Lower My Blood Pressure
If diet, exercise and other lifestyle changes dont work to lower your blood pressure, your healthcare provider will prescribe medications to help lower your blood pressure. Your provider will take into account other conditions you may have, such as heart or kidney disease and other drugs youre taking when prescribing medications to treat your high blood pressure. Be sure to follow your providers dosing directions exactly.

Looking For A List Of Symptoms
If you are looking for a list of symptoms and signs of high blood pressure , you wont find them here. This is because most of the time, there are none.
Myth: People with high blood pressure will experience symptoms, like nervousness, sweating, difficulty sleeping or facial flushing.
Truth: High blood pressure is a largely symptomless silent killer. If you ignore your blood pressure because you think a certain symptom or sign will alert you to the problem, you are taking a dangerous chance with your life.
What Medications Are Used To Treat High Blood Pressure
Four classes of high blood pressure medications are considered first line when starting treatment. Sometimes other medications are coupled with these first-line drugs to better control your high blood pressure. First-line, pressure-lowering medications are:
- Angiotensin-converting enzyme inhibitors block the production of the angiotensin II hormone, which the body naturally uses to control blood pressure. When angiotensin II is blocked, your blood vessels dont narrow. Examples: lisinopril , enalapril or captopril.
- Angiotensin II receptor blockers block this same hormone from binding with receptors in the blood vessels. ARBs work the same way as ACE inhibitors to keep blood vessels from narrowing. Examples: metoprolol , valsartan or losartan.
- Calcium channel blockers prevent calcium from entering the muscle cells of your heart and blood vessels, allowing these vessels to relax. Examples: amlodipine , nifedipine , diltiazem .
- Diuretics flush excess sodium from your body, reducing the amount of fluid in your blood. Diuretics are often used with other high blood pressure medicines, sometimes in one combined pill. Examples: indapamide, hydrochlorothiazide or chlorothiazide.

Can High Blood Pressure Be Prevented Or Avoided
If your high blood pressure is caused by lifestyle factors, you can take steps to reduce your risk:
- Reduce your alcohol consumption.
- Learn relaxation methods.
If your high blood pressure is caused by disease or the medicine you take, talk to your doctor. He or she may be able to prescribe a different medicine. Additionally, treating any underlying disease can help reduce your high blood pressure.
What Is High Blood Pressure
High blood pressure, also called hypertension, is blood pressure that is higher than normal. Your blood pressure changes throughout the day based on your activities. Having blood pressure measures consistently above normal may result in a diagnosis of high blood pressure .
The higher your blood pressure levels, the more risk you have for other health problems, such as heart disease, heart attack, and stroke.
Your health care team can diagnose high blood pressure and make treatment decisions by reviewing your systolic and diastolic blood pressure levels and comparing them to levels found in certain guidelines.
The guidelines used to diagnose high blood pressure may differ from health care professional to health care professional:
- Some health care professionals diagnose patients with high blood pressure if their blood pressure is consistently 140/90 mm Hg or higher.2 This limit is based on a guideline released in 2003, as seen in the table below.
- Other health care professionals diagnose patients with high blood pressure if their blood pressure is consistently 130/80 mm Hg or higher.1 This limit is based on a guideline released in 2017, as seen in the table below.
|systolic: 130 mm Hg or higherdiastolic: 80 mm Hg or higher|
If you are diagnosed with high blood pressure, talk with your health care team about your blood pressure levels and how these levels affect your treatment plan.

What Can I Expect If I Have This Condition
Since high blood pressure doesnt cause many symptoms at first, you probably wont feel any different with a high blood pressure diagnosis. But its important to follow your providers instructions to bring your blood pressure down so it doesnt cause serious illnesses later in life.
How long does high blood pressure last?
If you have primary high blood pressure, youll need to control it for the rest of your life.
If you have secondary high blood pressure, your blood pressure will most likely come down after you receive treatment for the medical problem that caused it. If a medication caused your high blood pressure, switching to a different medicine may lower your blood pressure.
What is the outlook for high blood pressure?
You can get seriously ill if you dont treat your high blood pressure. However, if you take the medicines your provider ordered, you can control your blood pressure. Exercising and eating healthy foods also helps lower your blood pressure.
Secondary High Blood Pressure
Some cases of high blood pressure are the result of underlying factors or cause and this is known as secondary high blood pressure.
Underlying factors include:
- kidney conditions, such as a kidney infection, or kidney disease
- narrowing of the arteries
- hormonal conditions, such as Cushing’s syndrome
- conditions that affect the bodys tissue, such as lupus
- medication, such as the oral contraceptive pill, or the type of painkillers that are known as nonsteroidal anti-inflammatory drugs , such as ibuprofen
- recreational drugs, such as cocaine, amphetamines and crystal meth
Occasionally, a rise in blood pressure can result from taking herbal remedies, such as herbal supplements.

What Is The Treatment For High Blood Pressure
- limiting your alcohol intake to no more than 2 drinks per day for men, or 1 drink per day for women with high blood pressure
However, lifestyle changes may not be enough. Some people also need medication to help reduce blood pressure levels to normal. While medicines are usually very effective at lowering blood pressure, they may cause side effects in some people.
Usually doctors will start a person on a low dose of a medicine and see how it goes. If it doesnt work well enough, or if there are troublesome side effects, other medicines will be used, sometimes in combination, until the blood pressure is controlled. This can take time. Some people will take medicines for life, although others will find that continuing to lose weight and changing their diet reduces the need for medicines.
Someone whose blood pressure is very high or causing symptoms such as headache, or if they have conditions such as heart disease or diabetes, may need urgent treatment with medicines to bring the blood pressure down to normal levels.
The Royal Australian College of General Practitioners recommends that you regularly review with your doctor or specialist any medications you are taking for high blood pressure or high cholesterol to assess the ongoing benefits and risks.

Maintain A Healthy Weight
Being overweight is a risk factor for having high blood pressure, and your risk increases further if you are obese.
There are two ways to check if you are overweight:
- Body Mass Index – This is your weight in kilograms divided by your height in metres squared. In the UK, people with a BMI of between 25 to 30 are overweight, and those with an index above 30 are classed as obese. People with a BMI of 40 or more are morbidly obese.
- Waist size – Using a measuring tape place the tape round your waist between the bottom of your ribs and the top of your hip bone. The table below indicates how much your health might be at risk, your ethnicity should also be taken into account.
|Over 80 cm|
The best way to tackle obesity is by reducing the amount of calories that you eat, and taking regular exercise. Your GP can provide you with further information and advice on how you can do this.

Drink Alcohol In Moderation
Drinking excessive amounts of alcohol will increase your blood pressure and raise the cholesterol levels in your blood.
Sticking to the recommended amounts of alcohol consumption is the best way to reduce your risk of developing high blood pressure.
The recommended daily limits of alcohol consumption are:
- 3 to 4 units of alcohol for men
- 2 to 3 units of alcohol for women.
A unit of alcohol is equal to about half a pint of normal-strength lager, a small glass of wine or a pub measure or spirits.
