A blood pressure of 57/45 indicates that you have SEVERE HYPOTENSION, or extremely low blood pressure, although it is not officially classified by American Heart Association.
Such a critical reading necessitates immediate medical attention or possibly hospitalization, applicable to all—children, adults, the elderly, and pregnant individuals.
If left untreated, it can lead to serious health repercussions like organ failure or impaired oxygen delivery to the body.
It’s important to note that ‘ideal’ blood pressure may vary, influenced by age, gender, weight, and overall health, and individual medical history and current health conditions must be considered.

What does a 57 over 45 (57/45) blood pressure mean?
A blood pressure reading of 57/45 mmHg signifies the presence of severe hypotension, a critical medical condition requiring immediate attention.
Clinically, this state is managed by administering medication that diminishes the contractility of blood vessels, aiding in the restoration of stable blood pressure.
Severe hypotension is diagnosed when blood pressure readings fall below 80/60, posing a life-threatening risk if it further decreases to below 50/35.
Here is a blood pressure chart according to the latest guidelines of American Heart Association (AHA).

A study published in Aging Mental Health reported that approximately 30% of the senior population may be experiencing hypotension.1
The optimal blood pressure range for an individual is between [90/60] and [120/80]. A reading below this range typically indicates hypotension.
In instances of severe hypotension, the heart struggles to circulate blood throughout the body. While some organs can withstand this temporary deprivation, the human brain is particularly vulnerable, unable to survive without oxygen for more than four minutes.
It is imperative to understand that while low blood pressure is concerning, severe hypotension is a medical emergency that necessitates immediate reporting to a healthcare professional.
In some scenarios, severe low blood pressure may also indicate additional clinical complications such as organ damage or internal bleeding, underscoring the importance of prompt medical intervention.
Individuals experiencing severe hypotension will likely encounter distinct physiological symptoms, prompting them to seek medical assistance. If your blood pressure is at 57/45 mm/Hg, you may experience the following symptoms:
- Profound confusion
- Loss of balance
- Nausea, dizziness, and fainting
- Weak pulse
- Blurred vision
- Pallor and cool skin
- Impaired concentration or peripheral awareness

What should you do if you have 57 over 45 (57/45) blood pressure?
Here is a set-by-step procedure to follow when you figure out you have a blood pressure of 57/45.
1. Consult your doctor for accurate blood pressure reading
If your blood is 57/45 and you have checked the same in your home setup, it is highly recommended to get it checked at your doctor’s office.
A trained professional has to clinically assess your condition and confirm that your 57/45 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
If you think you have severe hypotension, the first and foremost thing is to get in touch with your local medical care facility.
Since confusion and vertigo may happen, it is advised not to drive yourself to the hospital.
Unless your blood pressure hasn’t dipped to dangerous levels, you may make reasonable changes in your lifestyle to improve your blood pressure to a significant level.
According to a review from P&T Journal, here are some of the changes that you can bring into your lifestyle to improve your health and your blood pressure level 3:
- Increase the consumption of sodium salts.
- Increase the consumption of water, and keep yourself hydrated at all times.
- Eat low-carb healthy meals and exercise daily.
- Maintain a healthy body weight.
- Ensure a good emotional atmosphere around you (no stress and anxiety).
- Quit smoking and limit the consumption of alcohol.
3. Consider using medications for blood pressure management
Undoubtedly, at this point, you may want to use some medications for the good of your health. However, based on the diagnosis, it should be prescribed by your doctor.
According to a clinical review by U.S. Pharmacist, the following medicines are highly beneficial for individuals experiencing low blood pressure. 4
- Corticosteroids: These are the types of medicines that control the amount of sodium present in our blood. By regulating that particular concentration of sodium in blood, they raise the blood pressure of the individual.
- Alpha-adrenergic Agonists: These are the types of medicines that promote the contraction of blood vessels. As a result of this contraction, the pressure of blood over the vessels increases, and the body supports an ideal blood pressure.
- Angiotensin II: This type of medicine increases the extent of retention of sodium in the kidneys, and that contributes to the rise of blood pressure in the body of a person.
- Decongestants: These medicines help reduce the size of the swollen blood vessels and result in the contraction of the said blood vessels. This, as a result, leads to an increase in blood pressure.
- Immunosuppressants: These medicines promote the solubility of the sodium ions in your blood, as a result increasing its concentration. This contributes to rising in the BP of the individual.
4. Plan a diet specifically for 57/45 blood pressure
Like how you would be managing your diet for hypertension, even hypotension patients need to have a check on their dietary habits. Some of the foods are a big no-no, while certain foods need to be included on a strict note.
According to a report in Harvard Health Letters, incorporating the following items into your diet can help bring your blood pressure to healthy levels. 5
- Drink more: Hydration is key for all health conditions, so you should drink lots of fluids to increase blood volume.
- Sodium: Table salts are rich in sodium, a necessary component that helps retain water in the blood to increase its volume.
- Vitamin B12: When you are deficient in this vitamin, you may experience anemia and hypotension. Try adding eggs, cereals, meats, etc., into your diet.
- Caffeine: Caffeinated beverages are good stimulants that temporarily cause a surge in blood pressure and adrenalin levels.
- Say no to junk food: you should avoid the consumption of foods that are rich in carbs. Take small meals multiple times a day for the best of benefits.
5. Be aware of the underlying causes and risks of 57/45 blood pressure
Some of the comorbidities associated with low blood pressure include heart attack, cardiac arrest, heart valve disorder, bradycardia, and hormonal imbalance.
When you have 57/45, then you may want to rectify the root cause by visiting your physician.
Age is one of the major risk factors, and people older than 65 may have a sudden drop in blood pressure after eating food or while standing up.
In some cases, neural, mediated blood pressure decrease is noted in children and young adults as well.
A study from The American Geriatrics Society reports that depression is one of the significant causes that lead to hypotension, and vice versa. 6
Even stress is linked to hypotension in some patients. Since the human body reacts differently to different situations, not necessarily depression and anxiety lead to hypertension, but hypotension too.
Some of the medications that you might be using can cause severe hypotension. Therefore, it is important to inform your doctor about your pre-existing medical conditions when getting a new prescription.
6. Try natural supplements to support healthy blood pressure level
Sometimes managing blood pressure is all about supplementing your body with the right diet. Food is undoubtedly the best primary source to supplement your body.
However, in the current scenarios, we all know how much adultered our foodstuff is, and most of us are pushed towards processed foods to feed ourselves in this fast-paced world.
All these food are high in sugar and sodium and doesn’t contain any vital nutrients that are important for a healthy heart.
This is where some of the nutraceutical-based blood pressure supplements come in handy. These products combine all critical nutrients your heart craves, thereby assisting the better function of your cardiovascular system.
A team of researchers from Shahrekord University of Medical Sciences in Iran compiled a list of medicinal botanicals with anti-hypotensive capabilities. Today, most nutraceutical blood pressure supplements are made using these botanicals as their major ingredients. 7
Generally, these supplements are a concoction of herbs, plant-based products, dairy products, and some animal products. They are 100% organic and natural and don’t contain any harmful chemicals.
If you are hearing about these segments of products for the first time, to start with, you may blindly go for 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.
The only one thing to keep in mind is that choose the best blood pressure supplements that lower blood pressure, because when it comes to the heart, there is no taking of risk!
Severe hypotension might look scary, but consistent monitoring and timely medical care can easily be handled.
If you are someone suffering from hypotension for quite some time, it is better to inform your kin, peers, and colleagues about the condition so that, in the unlikely event, people can make a smart choice.
If you follow your diet correctly, use some supplementation, and exercise daily, then hypotension can slowly be eliminated from your life.

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 severe hypotension?
Severe hypotension is a medical condition characterized by dangerously low blood pressure levels, which can have serious consequences for the body.
A blood pressure reading of 90/60 is generally considered low, but when it drops by 10 points to 80/50, it is classified as severe hypotension.
What do systolic and diastolic numbers mean in severe hypotension?
In severe hypotension, the systolic and diastolic numbers in a blood pressure reading take on specific meanings related to the condition.
These values provide essential insights into cardiovascular health.
Systolic Number (the higher of the two)
- Reflects the pressure in your arteries during each heartbeat.
- In hypotension, a low systolic reading indicates reduced force exerted by the heart when pumping blood.
- This can lead to inadequate blood flow to vital organs, causing symptoms like dizziness and fainting.
Diastolic Number (the lower of the two)
- Represents the arterial pressure when the heart rests between beats.
- In hypotension, a low diastolic reading may indicate that the heart is not effectively refilling or that there’s insufficient blood volume.
- This can result in inadequate oxygen delivery to tissues and may contribute to symptoms such as fatigue and weakness.
How does severe hypotension affect blood pressure?
Severe hypotension has a profound impact on blood pressure, leading to a significant drop in the circulatory force vital for proper bodily function.
This condition affects blood pressure in several ways.
- Sharp Decrease: Severe hypotension causes a rapid reduction in both systolic and diastolic blood pressure readings.
- Reduced Organ Perfusion: Inadequate blood supply to vital organs can result in organ dysfunction or failure.
- Symptoms: It often leads to symptoms like dizziness, fainting, and weakness due to insufficient blood flow.
- Increased Health Risks: Prolonged severe hypotension can increase the risk of complications, such as shock or organ damage.
What are the symptoms of a severe hypotension?
Symptoms of severe hypotension, a condition characterized by dangerously low blood pressure, can manifest in various ways, often causing significant discomfort and potential health risks.
When blood pressure drops to critically low levels, individuals may experience the following.
- Profound Dizziness and Lightheadedness
- Blurred Vision
- Nausea and Potential Vomiting
- Cold, Clammy Skin
- Rapid or Weak Pulse
- Overwhelming Fatigue and Weakness
- Fainting or Loss of Consciousness
These symptoms reflect the body’s struggle to maintain adequate blood flow to vital organs and should be treated as a medical emergency, necessitating immediate attention.
