How Can You Reduce Your Risk Of High Blood Pressure
Fortunately, there are certain things you can do to help reduce your risk of developing high blood pressure. These include the following:
- Eat right: A healthy diet is an important step in keeping your blood pressure normal. The DASH diet emphasizes adding fruits, vegetables and whole grains to your diet while reducing the amount of sodium. Since its rich in fruits and vegetables, which are naturally lower in sodium than many other foods, the DASH diet makes it easier to eat less salt and sodium.
- Keep a healthy weight: Going hand-in-hand with a proper diet is keeping a healthy weight. Since being overweight increases your blood pressure, losing excess weight with diet and exercise will help lower your blood pressure to healthier levels.
- Cut down on salt: The recommendation for salt in your diet is to have less than 1,500 milligrams of sodium a day . To prevent hypertension, you should keep your salt intake below this level. Don’t forget that most restaurant foods and many processed and frozen foods contain high levels of salt. Use herbs and spices that do not contain salt in recipes to flavor your food do not add salt at the table.
- Keep active: Even simple physical activities, such as walking, can lower your blood pressure .
- Drinkalcoholin moderation: Having more than one drink a day and two drinks a day can raise blood pressure.
When To Contact A Medical Professional
If low blood pressure causes a person to pass out , seek treatment right away. Or call 911 or the local emergency number. If the person is not breathing or has no pulse, begin CPR.
- Black or maroon stools
Hypotension Blood pressure – low Postprandial hypotension Orthostatic hypotension Neurally mediated hypotension NMH
This Is Why You Have High Blood Pressureand How To Lower It
Blood pressure is probably one of those health characteristics youve heard about all your life, but havent paid much attention to your doctors readings before reaching the age range where it could become a concern. If this is the case, youre not alone.
If youre also wondering what blood pressure even is, youre also not alone there, either. Basically, the body possesses an intricate framework of blood vessels that is composed of two specific types: arteries and veins, says Suneet Singh, MD, an emergency room physician and medical director at CareHive in Austin, Texas. Blood that goes out of the heart is found within arteries while blood that returns is found within veins. Blood pressure is the measurement of the pressure of blood against the walls of blood vessels. According to the American Heart Association, normal blood pressure is less than 120/80.
In general, when we discuss blood pressure, we are referring specifically to the pressure found within arteries because this is what correlates most with acute and chronic diseases, Dr. Singh explains. When people demonstrate a consistent pattern of pressures over this number, they are diagnosed with high blood pressure, also called hypertension.

Regular Blood Pressure Checks If Diagnosed With High Blood Pressure
If you are diagnosed with high blood pressure, your blood pressure will need to be closely monitored until it is brought under control.
After your blood pressure has been controlled, your GP or practice nurse will measure your blood pressure at agreed regular intervals .
It is important you attend these appointments to ensure your blood pressure is being maintained within an acceptable range.
Why Is Your Blood Pressure Important
Your blood pressure is important because if it is too high, it affects the blood flow to your organs. Over the years, this increases your chances of developing heart disease, stroke, chronic kidney disease, eye disease, erectile dysfunction and other conditions.
Very occasionally, people with very high blood pressure are at serious risk of problems and need urgent treatment in hospital to reduce the risk of a stroke or heart attack.
Current Australian guidelines recommend that if you have persistent raised blood pressure over 160/100 mmHg, but are at low risk of having a stroke or heart attack, you should talk to your doctor or specialist about taking medication to lower your blood pressure.

If youre over 18, you should have your blood pressure checked by your doctor at least every 2 years, or more often if advised.

What Causes Hypertension
The causes depend on the type of hypertension: primary and secondary. Sometimes the blood pressure may suddenly increase, with or without any history of hypertension. These sudden spikes typically last for a short time and are called sudden high blood pressure or hypertensive urgency. The blood pressure may often return to normal after a while.
Primary or essential hypertension
In most adults, there is no identifiable cause for hypertension. Primary or essential hypertension is not caused by a disease or health condition.
Primary hypertension can result due to multiple factors:
- Genetics
- Physical changes in the body due to age
- Salt sensitivity
Secondary hypertension
In some people, hypertension is caused by an underlying health condition. This is called secondary hypertension and tends to appear suddenly. Secondary hypertension causes higher blood pressure than primary hypertension.
Secondary hypertension is caused by specific conditions and their complications, such as
- Kidney disease
How Is It Diagnosed
Because it is such a common problem, blood pressure is checked at most healthcare visits. High blood pressure is usually discovered during one of these visits. If your blood pressure is high, you will be asked to return for follow-up checks. If repeated checks of your blood pressure show that it is higher than 140/90, you have hypertension.
Your healthcare provider will ask about your life situation, what you eat and drink, and if high blood pressure runs in your family. You may have urine and blood tests. Your provider may order a chest X-ray and an electrocardiogram . You may be asked to use a portable blood-pressure measuring device, which will take your pressure at different times during day and night. All of this testing is done to look for a possible cause of your high blood pressure.

Youre Feeling Lonely Or Socially Isolated
You may not necessarily feel stressed when you experience loneliness or social isolation, but these feelingswhen they persistcan trigger the same dangerous release of stress hormones that spike blood pressure, says Dr. Beniaminovitz. Not to mention, chronic loneliness is associated with depression, and research has shown a correlation between depression, subsequent weight gain, and increase in blood pressure.
BP fix: Make more plans with friends.
We are social beings and we need a certain amount of social interaction to function optimally, says Dr. Beniaminovitz. But if the idea of putting yourself out there seems impossible, start small. Send a friend a quick DM to say youre thinking of them, and see where things go. Combine physical activity and social time by committing to a weekly Saturday morning yoga class with a pal. Want to make new friends? Try volunteering to meet like-minded people.
Is There Is A High Blood Pressure Diet
In about half of people with high blood pressure, limiting sodium intake by eliminating table salt, cooking salt, and salty and processed foods can reduce blood pressure by 5 mm Hg. Losing weight and participating in regular physical activity can reduce blood pressure further.
If these lifestyle changes and choices don’t work, medications should be added. The medications have been proven to reduce the risk of stroke, heart disease, and kidney problems.
Weight Control
- Aim for a healthy weight range for your height and body type. Your health care practitioner can help you calculate a healthy target weight.
- Even a small amount of weight loss can make a major difference in lowering or preventing high blood pressure.
- You must burn more calories than you take in to lose weight.
- Crash or fad diets are not helpful and may be dangerous.
- Some weight loss medications also carry major risks and may even elevate blood pressure, and great caution is advised in using these drugs. Please ask your health care practitioner or pharmacist for help in deciding if a weight loss medication is appropriate for your situation.

What Is High Blood Pressure
Blood pressure is the force of your blood as it flows through the arteries in your body. Arteries are blood vessels that carry blood from your heart to the rest of your body. When your heart beats, it pushes blood through your arteries. As the blood flows, it puts pressure on your artery walls. This is called blood pressure.
High blood pressure happens when your blood moves through your arteries at a higher pressure than normal. Many different things can cause high blood pressure. If your blood pressure gets too high or stays high for a long time, it can cause health problems. Uncontrolled high blood pressure puts you at a higher risk for stroke, heart disease, heart attack, and kidney failure.
There are 2 types of high blood pressure.
Primary hypertension. This is also called essential hypertension. It is called this when there is no known cause for your high blood pressure. This is the most common type of hypertension. This type of blood pressure usually takes many years to develop. It probably is a result of your lifestyle, environment, and how your body changes as you age.
Secondary hypertension. This is when a health problem or medicine is causing your high blood pressure. Things that can cause secondary hypertension include:
- Kidney problems.
- Thyroid or adrenal gland problems.
- Some medicines.
When To See A Doctor
Although high blood pressure does not usually cause symptoms, anyone experiencing a sudden, severe headache or nosebleed should check their blood pressure.
If their blood pressure is above 180/120 mm Hg, they should stay rested for 5 minutes and recheck their blood pressure. If the blood pressure is still higher than 180/120 mm Hg, they need to seek medical help at their doctors office.
If a person is experiencing severe symptoms, such as chest pain, shortness of breath, or visual difficulty, they need to call 911 for emergency medical treatment as they may be experiencing a hypertensive crisis.
Medications to reduce blood pressure can cause side effects such as dizziness. If this side effect does not go away or affects a persons daily activities, they should speak with their family doctor.

Can You Prevent High Blood Pressure
High blood pressure may be prevented by living a healthy lifestyle include:
- Eat a nutritious, low-fat diet. The National Heart, Lung and Blood Institute of the NIH outlines the DASH diet, that is describes as a “flexible and balanced eating plan that helps create a heart-healthy eating style for life.”
- Get regular exercise.
- Maintain a healthy weight, and if you are overweight or obese, try to lose weight.
- Drink alcohol in moderation.
When To Call Your Doctor
Talk to your doctor if you experience a sudden drop in blood pressure accompanied by lightheadedness or dizziness. Take note of how fast your blood pressure drops rather than how much it drops any time you feel dehydrated, spend too much time in the hot tub or in the sun, or have low blood sugar. Keep a diary and record any symptoms and the corresponding activity at the time.
If you have liver or kidney problems, have had a stroke or are at risk of having a stroke, you should have your blood pressure closely monitored. Low blood pressure can interfere with blood supply to your organs and the brain.

What Are The Consequences Of Morning Hypertension
Those with morning hypertension have a higher risk for heart attack, stroke and sudden death in the first few hours of the morning compared with those without morning hypertension.
If you experience symptoms such as severe headache, chest pain, and numbness or tingling in your face or arms, be sure to contact your doctor immediately.
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.
| Sex | |
| 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.

Living With High Blood Pressure
Controlling your high blood pressure is a lifelong commitment. You will always need to monitor your weight, make healthy food choices, exercise, learn to cope with stress, avoid smoking, and limit your alcohol intake. If you need medicine to control your high blood pressure, you will likely need it all your life.
Additionally, you will need to get used to regular blood pressure checks. Your doctor may want you to come to the office regularly. Or you may be asked to check your blood pressure at home and keep track of your numbers for your doctor. Some pharmacies and retail clinics have blood pressure machines on site. You can buy your own, automated arm blood pressure cuff for use at home. Your doctor may want you to check your blood pressure several times a day. Another option is to use an ambulatory blood pressure monitor.
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:
- Caffeine
- Certain medications or combinations of medications
- Chronic kidney disease

Why Does Blood Pressure Change
Remember that there are three factors controlling blood pressure at any one time:
- The force and rate of the heart contraction.
- The diameter of the blood vessels throughout the body.
- The volume and even viscosity of the blood.
It is further influenced by hormones, electrolytes and nerve impulses. The activity of all these factors collectively determine blood pressure. The entire system is complex and the body has to cater for changes to keep your body working optimally. Your blood pressure changes when you sit down, stand up or lie flat. It drops when you sleep soundly. It can fluctuate in hot or cold weather.
Here are 6 common reasons for a sudden increase in blood pressure.
Diagnosing High Blood Pressure
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.
Before having your blood pressure taken, you should rest for at least five minutes and empty your bladder. To get an accurate blood pressure reading, you should be sitting down and not talking when the reading is taken.
Having one high blood pressure reading does not necessarily mean that you have high blood pressure. Your blood pressure can change throughout the day. Feeling anxious or stressed when you visit your GP can raise your blood pressure .
Therefore, your GP will need to take several readings over a set period of time, usually every month, to see whether your blood pressure level is consistently high.
Blood and urine tests may also be carried out in order to check for conditions that are known to cause an increase in blood pressure, such as kidney infections.
You may also be given a blood pressure device to take home so that you can record your blood pressure level throughout the day. This also helps to identify white coat syndrome and therefore helps to identify the best treatment options for you.

What Medications Treat High Blood Pressure
- Of appropriate, chlorthalidone is the preferred diuretic.
Beta-Blockers
- Beta-blockers reduce heart rate and decrease the force of heart contraction by blocking the action of adrenaline receptors. Beta blockers are widely prescribed and effective but can cause increased fatigue and decreased exercise tolerance because they prevent an increased heart rate as a normal response to physical activity.
- They are also prescribed for people who have associated heart disease, angina, or history of a heart attack.
- Examples of beta blockers include, carvedilol , metoprolol , atenolol
Calcium Channel Blockers
- Calcium channel blocking agents work by relaxing the muscle in artery walls and by therefore reducing the force of contraction of heart muscle.
- Example of calcium channel blockers include, nifedipine , diltiazem , verapamil , nicardipine , amlodipine , and felodipine
Angiotensin-Converting Enzyme Inhibitors
- ACE inhibitors stop the production in the body of a chemical called angiotensin II, which causes blood vessels to contract. Narrower blood vessels are associated with increased blood pressure. Relaxing artery walls leads to lower blood pressure.
- Examples of ARBs include losartan , valsartan , candesartan , and irbesartan
Blockers of Central Sympathetic System
Direct Vasodilators
Take your high blood pressure medicine as prescribed and only discontinue them on the advice of your doctor or other healthcare professional.
