Understanding Blood Pressure Charts: What Your Numbers Mean for Your Health

Your body pumps blood every time the heart beats, known as the circulatory system. Blood passes through the arteries and carries nutrients and oxygen to organs, cells, tissues, and your overall system. Thus, aiming to have normal blood pressure is key to well-being. Let us understand what blood pressure numbers mean.

Systolic Blood Pressure Number

The heart squeezes and pushes blood when it beats. The blood creates pressure (force) on the blood vessels as it passes the arteries, which is systolic blood pressure. The blood pressure levels for systolic readings are:

• The normal level is 120mm Hg
• Elevated level is 120-129mm Hg
• Stage 1 high blood pressure is 130-139mm Hg
• Stage 3 hypertension is 140mm Hg or above

Diastolic Blood Pressure Number

The bottom number, known as the diastolic reading, is the pressure created as the heart rests between each pumping of blood or rather heartbeats. The heart at this stage, gets filled with blood and receives oxygen. Know the blood pressure monitor for diastolic numbers here:

• The normal level is less than 80mm Hg
• The blood pressure readings for Stage 1 hypertension are 80 and 89mm Hg
• Stage 2 high blood pressure is 90mm Hg or more
• If the number is lower than 80mm Hg but the systolic number is between 120 and 129mm Hg, you may have an elevated blood pressure

Insight into Blood Pressure Levels

The blood pressure level is categorized as normal, elevated, low, stage 1 hypertension, stage 2 hypertension, and hypertensive crisis. Let us know these in detail:

1. Normal

If the blood pressure reading is 120/80 mm Hg, then the numbers are in ideal range. You can maintain normal blood pressure through regular exercise, a healthy diet, and sufficient sleep.

2. Low

If your blood systolic reading is less than 90mm Hg, it indicates low blood pressure or hypotension. The symptoms include fainting, tiredness, and dizziness, etc. Diseases, dehydration, and infections are common causes here. The condition needs proper treatment and lifestyle changes.

3. Elevated

If the blood pressure is less than 80mm Hg diastolic with a range between 120mm Hg and 129mm Hg systolic, then you are at risk of high blood pressure, which you must rectify through exercises and changes in your diet and lifestyle.

4. Stage 1 Hypertension

If your blood pressure is high between 80 and 89mm Hg and/or 130 and 139mm Hg systolic, then you are at risk of heart attack and cardiovascular diseases. Your doctor may recommend a blood pressure monitor tool to check the readings regularly, medications, and lifestyle changes.

5. Stage 2 hypertension

When your blood pressure is high with consistent readings of 90mm Hg diastolic or higher and/or 140mm Hg systolic or higher, your heart pumps blood very hard. This may impact the kidneys, brain, and other organs because the pressure created may damage the muscles and blood vessels.

6. Hypertensive Crisis

If you have severe high blood pressure with a reading above 120mm Hg diastolic and/or 180mm Hg systolic, you may require immediate medical attention or emergency care. Get a doctor on call to monitor the blood pressure and understand the detailed evaluation without delay.

The body function may differ according to gender and age. To understand the normal blood pressure range, go through the following:

• For newborns up to 1 month, the normal levels for systolic and diastolic are 60-90mm Hg and 20-60mm Hg, respectively.
• For infants, the systolic reading is between 87 and 105mm Hg, while that for diastolic is 53 to 66mm Hg.
• For toddlers, the diastolic and systolic numbers are 53-66mm Hg and 95-105mm Hg, respectively.
• For preschoolers, the diastolic and systolic numbers are 56-70mm Hg and 95-110mm Hg, respectively.
• The blood pressure chart by age for school-aged kids is 57-71mm Hg diastolic and 97-112mm Hg systolic, while that for adolescents is 66-80mm Hg diastolic and 112-128mm Hg systolic.
• The average readings for normal blood pressure for women aged 18-39, 40-59, and 60+ are 110/68 mm Hg, 122/74 mm, and 139/68 mm, respectively.
• The average readings for normal blood pressure for adult males aged 18-39, 40-59, and 60+ are 119/70 mm Hg, 124/77 mm Hg, and 133/69 mm, respectively.

Did you know? Recent studies suggest that your blood pressure readings can vary significantly based on the time of day and even your stress levels. Learning to interpret these variations can provide deeper insights into your cardiovascular health.

A blood pressure monitor (aneroid or digital) helps to provide your current blood pressure level. It is helpful to track the readings, especially if you have a history of high or low blood pressure, and wish to keep it in check. Consider a recognized brand when you purchase a blood pressure machine, and look for the right cuff size, ease of use, and cost.

1. Aneroid Blood Pressure Monitor

The aneroid blood pressure machine has a gauge that checks your blood pressure manually. The cuff comprises a built-in stethoscope that you wrap around your upper arm. Then you squeeze the rubber bulb with your hand. The cuff inflates and you read the blood pressure level as per the pointer’s level on the dial. You have to listen to your heartbeat when using the monitor. The device is portable but complex. Also, it becomes less accurate with time and damage.

2. Digital Blood Pressure Machine

A digital blood pressure monitor comprises a stethoscope and gauge in a single unit. It is more expensive than an aneroid device. However, the device contains an error indicator, is easy to use at home, and does not require hearing heartbeats manually. The cuff inflation system is either manual or automatic. Also, it is more accurate with blood pressure readings, ultra-portable in small size, light in weight, and with a digital display screen (not a dial) indicating the blood pressure. Some units also have a system of paper printouts recording the reading.

To sustain normal blood pressure, you may need to change your lifestyle, learn the symptoms to watch out for to prevent abnormal readings, know when to consult a doctor, and the possible medicines.

Lifestyle Changes for Optimum Blood Pressure Levels

Exercise regularly to maintain your weight. Include whole grains, vegetables, fruits, and low-fat dairy products in your diet. Avoid consuming items high in saturated fats and sugar. Sodium causes fluid retention in the blood. Thus, for normal blood pressure reduce the salt intake to 2.4 grams per day. Quit smoking and limit alcohol consumption. Reduce stress and get a good amount of sleep.

When to Seek Medical Help

If low blood pressure causes too much weakness, dizziness, and fainting, it can lead to shock. Some warning signs are blue skin tone, rapid pulse, rapid breathing, and clammy skin. Whereas, high blood pressure can damage your organs and elevate the risk of stroke, heart attack, and vascular dementia leading to a medical emergency in case of a hypertensive crisis. Symptoms of abnormal blood pressure levels to watch out for are shortness of breath, severe headaches, blurry vision, nosebleeds, anxiety, lightheadedness, chest pain, and severe headaches. In such instances, seek immediate consultation with a healthcare provider.

Blood Pressure Medications

To maintain normal blood pressure, your healthcare provider will take into account your symptoms, lifestyle practices, health, blood pressure readings over the past few days or weeks, history of diseases, and other parameters.

• For hypertension, the doctor may recommend Beta-blockers, Angiotensin-converting enzyme (ACE) inhibitors, Calcium channel blockers, diuretics, or Angiotensin receptor blockers (ARBs).
• Some medicines commonly prescribed for low blood pressure are Fludrocortisone and Midodrine.

Q. What is the normal blood pressure for adults?

The blood pressure level considered normal for adults is less than 120/80 mm Hg.

Q. How often should I check my blood pressure at home?

Those with hypertension or hypotension must get a digital blood pressure monitor to use at home and keep track of the readings every week, or as advised by their healthcare professional.

Q. What should I do if my blood pressure readings are consistently high?

High blood pressure readings indicate hypertension or a hypersensitive crisis. You may have to consult a healthcare provider, seek emergency care if necessary, and follow lifestyle changes and medication to lower your blood pressure.
