Side Effects Of Low Blood Pressure
Low blood pressure may not be discussed as often as high blood pressure, but it should be addressed, as prolonged low blood pressure can negatively affect your organs.
A certain amount of blood pressure is needed to maintain blood flow to the organs, says Dr. Wong. The blood supplies oxygen and nutrients to these organs. If the blood pressure is too low, an adequate blood supply cannot get to these organs.
If left untreated, low blood pressure can increase your risk of fainting, heart attack and organ damage, adds Dr. Desai.
Heart Rate Vs Blood Pressure
Blood pressure measures the force that moves blood through your blood vessels while your heart rate is the number of times your heart beats per minute. They are both important health indicators, but they are measured independently and dont necessarily increase or decrease synchronously.
A temporary increase in heart rate, such as during exercise, is not considered problematic. In fact, your heart is expected to rise during a bout of activity and return to its resting rate afterward. And the more intense you work, the more you should expect your heart rate to rise during exercise. Your heart rate can safely double during activity so long as it returns to its resting rate relatively soon after you finish your workout.
Significant increases in blood pressure, on the other hand, are not normal and should be monitored and shared with your health care provider.
What Are The Different Blood Pressure Categories
Blood pressure can be categorized into five different types, namely:
Normal: Blood pressure below 120/80 mm Hg is considered to be normal.
Elevated: When blood pressure readings consistently range from 120 to 129 systolic and less than 80 mm Hg diastolic, it is known as elevated blood pressure. People with elevated blood pressure are at risk of high blood pressure unless steps are taken to control it.
Hypertension stage I: In this condition, blood pressure readings consistently range from 130 to 139 systolic or 80 to 89 mm Hg diastolic. Doctors may prescribe blood pressure medications and some lifestyle changes to reduce the risk of heart diseases and stroke.
Hypertension stage II: In this condition, blood pressure readings consistently range from 140/90 mm Hg or higher. The doctors may prescribe a combination of both medications and lifestyle changes.
Hypertensive crisis: This is the most critical condition and requires emergency medical attention. In this condition, the blood pressure suddenly exceeds 180/120 mm Hg. Contact the physician immediately if the following symptoms are experienced:
- Difficulty speaking

What Is Normal Blood Pressure
For years we have been told that a normal blood pressure reading is 120/80 however, more and more doctors have now lowered these numbers to 115/75. Blood pressure is different for everyone as many factors can have an effect on the numbers.
Our blood pressure refers to the amount of force behind the blood as it hits the arterial walls. As the heart pumps the blood, an ideal pressure sees the blood push against the walls that are flexible enough to expand and retract easily. Over time, our age, diet, and physical activity play a role on the elasticity of our blood vessels. With a loss of flexibility due to hardening of the walls, the heart needs to work harder to push the blood.
These factors determine the blood pressure numbers. The systolic number is the top number, and it indicates the pressure as the heart beats or pushes the blood throughout the body. The diastolic number is the bottom number, and refers to the pressure in the arteries when the heart rests between beats. During this time, the heart receives oxygen as it fills with blood.
Isolated Systolic Hypertension In The Elderly
Systolic blood pressure rises steadily with age. This is due to the increasing stiffness of large arteries, long-term plaque buildup and an increased incidence of cardiovascular disease.
According to a recent study, persons who reached age 65, if they lived another 20 years, had a 90% lifetime risk of developing isolated systolic hypertension or high blood pressure 5.

What Are The Symptoms Of High Blood Pressure
The only way you can know for sure if you have high blood pressure is by having a nurse or doctor measure it. Monitoring your blood pressure at home also helps keep your blood pressure in check. Most often, high blood pressure is “silent,” meaning it has no other signs to warn you, according to the CDC.
What Questions Should I Ask My Provider
- Are there supplements or non-prescription medicines that I shouldnt take?
- Can I keep taking these medicines if I get pregnant?
- What kinds of exercise should I do?
A note from Cleveland Clinic
If you dont treat high blood pressure, it can put you at risk for developing serious illnesses later in life such as heart attack, kidney failure and stroke. But if you follow your providers instructions, you can control your blood pressure. Be sure to take any medicines your provider ordered as instructed. Keep taking them even if your blood pressure numbers begin to fall into the normal range. Living a healthy lifestyle by eating healthy foods, watching your weight and getting regular exercise is also a great way to help control your blood pressure.

What Does The Diastolic Blood Pressure Number Mean
The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen.
This is what your diastolic blood pressure number means:
- Normal: Lower than 80
- Stage 2 hypertension: 90 or more
- Hypertensive crisis: 120 or more. Call 911.
Our chart below has more details.
Even if your diastolic number is normal , you can have elevated blood pressure if the systolic reading is 120-129.

How Is Blood Pressure Measured
Blood pressure is measured in millimetres of mercury and is given as 2 figures:
- systolic pressure the pressure when your heart pushes blood out
- diastolic pressure the pressure when your heart rests between beats
For example, if your blood pressure is “140 over 90” or 140/90mmHg, it means you have a systolic pressure of 140mmHg and a diastolic pressure of 90mmHg.
As a general guide:
- ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg
- high blood pressure is considered to be 140/90mmHg or higher
- low blood pressure is considered to be 90/60mmHg or lower
How Is High Blood Pressure Treated
Treatment for hypertension depends on how high your blood pressure is, as well as your lifestyle and risk factors.
For elevated blood pressure, the goal is to keep your blood pressure from developing into clinical hypertension. No medications are necessary at this stage. Your doctor may recommend:
- losing weight if you have overweight or obesity
For stage 1 hypertension, your doctor may recommend lifestyle changes as mentioned above, as well as:
- reducing your sodium intake
- finding healthy ways to manage your stress
- medication, if your blood pressure doesnt improve after 1 month of lifestyle changes
For stage 2 hypertension, the typical treatment, in addition to a healthier lifestyle, is medication. Your doctor may prescribe one or more of the following medications to help lower your blood pressure:
- ACE inhibitors to block substances that tighten blood vessels
- alpha blockers to help relax the arteries
- beta-blockers to decrease your heart rate and block substances that tighten blood vessels
- calcium channel blockers to relax blood vessels and decrease the work of your heart
- diuretics to decrease the amount of fluid in your body, including your blood vessels
A hypertensive crisis requires immediate treatment. Medications may be given orally or intravenously .
The most for a hypertensive crisis include:
- vasodilators, such as hydralazine, nitroglycerin, and nitroprusside
- beta-blockers, such as labetalol and esmolol

Do I Have High Blood Pressure
Anyone can have high blood pressure. Some medical conditions, such as metabolic syndrome, kidney disease, and thyroid problems, can cause high blood pressure. Some people have a greater chance of having it because of things they can’t change. These are:
- Age. The chance of having high blood pressure increases as you get older, especially isolated systolic hypertension.
- Gender. Before age 55, men have a greater chance of having high blood pressure. Women are more likely to have high blood pressure after menopause.
- Family history. High blood pressure tends to run in some families.
- Race. African Americans are at increased risk for high blood pressure.
High blood pressure often has no signs or symptoms, but routine checks of your blood pressure will help detect increasing levels. If your blood pressure reading is high at two or more check-ups, the doctor may also ask you to measure your blood pressure at home.
There are important considerations for older adults in deciding whether to start treatment for high blood pressure if it is above 130/80, including other health conditions and overall fitness. Your doctor may work with you to find a blood pressure target that is best for your well-being and may suggest exercise, changes in your diet, and medications.

Having blood pressure that is either too high or too low can be extremely bad for your health. However, high blood pressure is particularly dangerous, as it can increase a persons risk of having a heart attack or stroke.
Age is one of the main factors affecting blood pressure. This means that what constitutes a normal or safe blood pressure range changes slightly as we get older.
What Is Normal Blood Pressure By Age
Blood pressure ranges for adults are:
- High: Systolic of 130 or above and/or diastolic of 80 or above
- High Blood Pressure Stage 1: Systolic of 130-139 or diastolic of 80-89
- High Blood Pressure Stage 2: Systolic of 140 or higher or diastolic 90 or higher
