A blood pressure of 137 over 81 (137/81) mmHg indicates that you are at risk of a ELEVATED BLOOD PRESSURE [PRE-HYPERTENSION], as per the latest guidelines from the American Heart Association.
While this reading doesn’t necessitate immediate hospitalization, it does prompt the need for regular monitoring and consultation with a healthcare professional.
This warning holds for all groups—children, adults, the elderly, and pregnant individuals—and if overlooked, can progress to more severe hypertension stages.
It’s important to understand that blood pressure can differ based on aspects like age, gender, weight, and overall health, with ‘normal’ levels varying based on an individual’s medical background and prevailing health conditions.

What should you do if you have 137/81 mmHg blood pressure?
Here is a set-by-step procedure to follow when you figure out you have a blood pressure of 137 over 81 mmHg.
1. Consult your doctor for accurate blood pressure reading
A trained professional has to clinically assess your condition and confirm that your 137/81 is, in fact, clinically valid.
There are instances when your reading at home setup might give you a reading which is incorrectly reported. It could be because of an error in reading it, damage to your device, your physical or mental condition on that particular day, etc.
Therefore, a doctor has to assess it over the course of 7 – 30 days periodically before he/she can confirm the accurate stage of your blood pressure.
In a study from the Aristotle University of Thessaloniki, researchers found something interesting about blood pressure readings.
Sometimes, when people are at the doctor’s office, their blood pressure reads high, but it’s normal when they check it elsewhere. They call this white coat hypertension.
On the flip side, some folks show normal readings at the doctor’s but have high readings at home or other places. This is known as masked hypertension 2
All these conditions are linked to physiology and psychology and, therefore, better to be validated by a doctor.
2. Adopt these lifestyle changes to regulate your blood pressure
Making definite changes in your lifestyle is sufficient to bring your blood pressure back in control or within the ideal range of blood pressure. These changes will be good enough to change your blood pressure to a better degree.
Following are the things that are to be considered when thinking of opting for a new lifestyle for yourself:
According to the National Center for Chronic Disease Prevention and Health Promotion guidelines, below are a few steps that you can incorporate to prevent prehypertension from affecting your life 3:
- Try getting adequate rest every day.
- Reduce the consumption of sodium salts.
- Support a healthy diet and exercise daily.
- Try to maintain a healthy weight.
- Quit smoking and drinking, or at least keep it in check.
- Manage your stress and anxiety.
3. Consider using medications for blood pressure management
Prehypertension can result from any medical condition or history of medical problems. Therefore, it is good to consider using medicines and prescribed drugs to keep your blood pressure in check.
A study from Appalachian State University suggests that prehypertension should be addressed with non-therapeutic approaches before resorting to medication. However, individuals with chronic kidney disease, diabetes, or preexisting medical conditions might need to rely on medicines. 4
Following are the medicines that are prescribed to individuals who are suffering from prehypertension:
- Water Pills: these are the medicines that control the amount of sodium that is mixed in with our bloodstream. By keeping it in check, it is possible to lower blood pressure rather significantly.
- Calcium Channel Blockers: these are the chemicals that block or restrict the intermixing of calcium minerals in the bloodstream. Calcium leads to the contraction of blood vessels.
- Renin Inhibitors: Renin inhibitors are the drugs that regulate the hormones and chemicals that are released by the kidneys, which leads to an increase in blood pressure.
- Beta Blockers: these are the medicines that help in regulate the heart bests. These help in slowing down the heart rate, which in turn leads to lower pressure over the heart walls and the blood vessels.
- Angiotensin Converting Enzyme Inhibitors: these are the chemicals that stop or restrict the formation of the compounds in the body that lead to the contraction of the blood vessels.
4. Plan a diet specifically for 137/81 blood pressure
The kind of foods that you include in your everyday diet can make a good-enough difference in your blood pressure. Therefore, if you were to keep your eating habits in check and behave well-disciplined regarding that, you will surely be able to maintain your blood pressure accordingly.
Following are some of the points that concern your diet which should be taken into consideration:
- Sodium intake: Sodium is a mineral that leads to an elevated level of blood pressure, which causes the problem of prehypertension.
- Caffeine: most the caffeine-products are known to increase blood pressure in individuals. If you are sensitive towards the usage of caffeine products, it will be good for you to give up on those entirely.
- Keep yourself hydrated: maintain the level of liquids and body fluids that are necessary for the transport of minerals and nutrients in your body.
- Sugar: Large consumption of sugar can lead to the problem of diabetes and, by extension, the issue of high blood pressure.
- Alcohol: To a certain extent, alcohol acts as a vasodilator. This will help in the relaxation of your blood vessels, which in turn will help maintain your blood pressure.
- Potassium salts: Instead of using sodium salts that lead to an increase in blood pressure, turn towards the usage of other salts.
5. Be aware of additional health risks linked to pre-hypertension
When you are diagnosed with prehypertension, you may want to keep track of a few other comorbidities because they can either get aggravated or initiated.
A study published in Nature Reviews Nephrology observed that prehypertension increases the risks of comorbidities such as obesity, diabetes mellitus, dyslipidemia, and inflammatory disorders.5
Your doctor may also prescribe certain medical checkups to rule out the possibility of damage to other organs. The following are the risks most likely to be associated with hypertension:
- History of heart problems.
- Genetic hypertension.
- Improper functioning of the kidney and pancreas.
- Not following a proper diet plan.
- Increased intake of sodium salts.
6. Try natural supplements to support healthy blood pressure level
Sometimes, managing blood pressure boils down to nourishing your body with the right diet. Undoubtedly, food is the best primary source for supplementation.
However, in today’s world, our food is often adulterated, and we gravitate towards processed foods due to our fast-paced lives. These processed foods are high in sugar and sodium, lacking essential nutrients crucial for a healthy heart.
This is where nutraceutical-based blood pressure supplements come in handy. These products amalgamate all the critical nutrients your heart craves, thereby promoting better cardiovascular function.
Typically, these supplements blend herbs, plant-based ingredients, dairy, and some animal products. They are 100% organic and natural, devoid of harmful chemicals.
A study in the British Journal of Clinical Pharmacology suggests that nutraceutical ingredients such as potassium, magnesium, L-arginine, vitamin C, cocoa flavonoids, and beetroot juice can significantly impact blood pressure. 6
If you’re new to these products, you can consider Blood Pressure Support from Vita Balance Inc., Blood Pressure Optimizer from HFL, or Corsanum, marketed by PLT Group.
Blood Pressure Support
Blood Pressure Optimizer
Blood Pressure Support combines hawthorn berry, olive leaf, hibiscus, and some vitamins like C, B6, B12, niacin, and folate alongside a bunch of other medicinal herbs to support the healthy working of the heart.
Blood Pressure Optimizer has MegaNatural®-BP grape seed extract and Celery3nB™ celery seed extract alongside common vitamins and minerals, which can help increase your cardiovascular elasticity.
Corsanum is a refined combination of olive, iron, and grapevine alongside regular products like coriander, hawthorn, and oregano, all of which are foods known to maintain cardiovascular health.
Just remember to carefully choose the best supplements that lower blood pressure because when it comes to your heart, there’s no room for risks.
Prehypertension isn’t a condition to take lightly. It may not warrant serious medication, but that can change swiftly.
Therefore, it’s wise to explore your best options.
Consult a physiotherapist before considering medication to make informed choices about your health.
What should you do when your blood pressure is 137/81 mmHg during pregnancy?
If your blood pressure is 137/81 during pregnancy, this falls into the range of elevated or prehypertension.

FAQ (Frequently Asked Questions)
What is the blood pressure?
Blood pressure is a measure of the force exerted by blood against the walls of the arteries as it is pumped by the heart.
When the heart beats, usually 60 to 100 times a minute, it sends blood through arteries that distribute oxygen and nutrients to the entire body.
These arteries transport blood from the heart to various body parts, and the pressure within them naturally fluctuates throughout the day.
What do the numbers on blood pressure readings chart mean?
The numbers on the blood pressure chart are a metric that helps you determine the health of your heart.
A quick, concise and accurate judgement about your heart can be drawn based on the range, difference, and intensity of these numbers.
They are often divided into two numbers, called systolic (force of blood in your arteries when your heart beats) and diastolic (force exerted when the heart is resting between betas) measurements.
Based on these pair of numbers, the blood pressure reading is classified into seven stages.
- Very Low Blood Pressure (Severe Hypotension): Below 80/50
- Low Blood Pressure (Hypotension): 80/50 – 90/60
- Normal Blood Pressure: 91/61 – 119/79
- Pre-Hypertension (Elevated Blood Pressure): 120/80 – 139/89
- High Blood Pressure (Stage 1 Hypertension): 140/90 – 159/99
- High Blood Pressure (Stage 2 Hypertension): 160/100 – 180/120
- Hypertensive Crisis: Above 180/120
What is a normal blood pressure?
Normal blood pressure, as recommended by the American Heart Association and cited by the National Institutes of Health, falls between 90 mmHg systolic, 60 mmHg diastolic and 120 mmHg systolic, 80 mmHg diastolic.
Perfect blood pressure is a measure that indicates the optimal force of blood against the walls of our arteries, ensuring efficient circulation without undue stress on the cardiovascular system.
It’s a balance that signifies good heart health and is a benchmark against which deviations, either high or low, are gauged.
What is a prehypertension (elevated blood pressure)?
Prehypertension, also referred to as “elevated blood pressure,” is a term used when a person’s blood pressure readings are somewhat higher than the typical normal range, but not high enough to be classified as hypertension.
For a clearer understanding, a standard blood pressure reading is usually around 120/80 mmHg. In the case of prehypertension, the systolic (the first number) may be up to 139, or the diastolic (the second number) can be up to 89.
To specify further, healthcare providers might label your blood pressure as “elevated” if your systolic measurement is between 120 and 129 while the diastolic is less than 80. If the systolic is between 130 and 139 and the diastolic is between 80 and 89, they might refer to it as “stage 1 high blood pressure.”
However, the term prehypertension encompasses both these conditions. If the blood pressure reaches 140/90 mmHg or above, it is then categorized as hypertension, which means high blood pressure.
How does prehypertension (elevated blood pressure) affect blood pressure?
Prehypertension affects blood pressure and health in several notable ways. It is often characterized by blood pressure readings ranging from 120/80 mmHg to just below 140/90 mmHg.
