Blood pressure is a measure of the force of blood against the walls of your arteries. It is expressed in units of mm Hg, with systolic blood pressure referring to the pressure when your heart beats and diastolic blood pressure referring to the pressure when your heart rests between beats. A healthy adult's blood pressure is usually below 120/80 mm Hg.
Low blood pressure, or hypotension, is defined as blood pressure lower than 90/60 mm Hg. It can be a sign of a number of serious medical conditions, including shock, sepsis, and heart failure. In some cases, low blood pressure can even be life-threatening.

If you experience symptoms of low blood pressure, it is important to seek medical attention immediately.
Can be a sign of serious medical conditions
Low blood pressure can be a sign of a number of serious medical conditions, including:
- Shock: Shock is a life-threatening condition that occurs when the body is unable to get enough blood to its organs. This can be caused by a number of factors, including severe bleeding, dehydration, and sepsis.
- Sepsis: Sepsis is a life-threatening condition that occurs when the body's response to an infection damages its own tissues. This can lead to organ failure and death.
- Heart failure: Heart failure is a condition in which the heart is unable to pump enough blood to meet the body's needs. This can be caused by a number of factors, including coronary artery disease, high blood pressure, and diabetes.
- Addison's disease: Addison's disease is a rare disorder in which the adrenal glands do not produce enough of the hormones cortisol and aldosterone. This can lead to low blood pressure, weight loss, and fatigue.
If you experience symptoms of low blood pressure, it is important to seek medical attention immediately. Early diagnosis and treatment of the underlying cause of low blood pressure can help to prevent serious complications.
Shock
Shock is a life-threatening condition that occurs when the body is unable to get enough blood to its organs. This can be caused by a number of factors, including severe bleeding, dehydration, and sepsis.
- Hypovolemic shock: This is the most common type of shock and is caused by a loss of blood or other fluids from the body. This can be caused by severe bleeding, dehydration, or burns.
- Cardiogenic shock: This type of shock is caused by a problem with the heart's ability to pump blood. This can be caused by a heart attack, arrhythmia, or cardiomyopathy.
- Distributive shock: This type of shock is caused by a problem with the distribution of blood in the body. This can be caused by sepsis, anaphylaxis, or neurogenic shock.
- Obstructive shock: This type of shock is caused by a blockage in the blood vessels. This can be caused by a pulmonary embolism, aortic dissection, or strangulation.
Shock is a medical emergency. If you suspect that someone is in shock, call 911 immediately. Symptoms of shock include:
- Rapid, weak pulse
- Cold, clammy skin
- Bluish lips and fingernails
- Shortness of breath
- Confusion or loss of consciousness
Sepsis
Sepsis is a life-threatening condition that occurs when the body's response to an infection damages its own tissues. This can lead to organ failure and death.
Sepsis is caused by a chain of events that begins with an infection. The infection can be caused by bacteria, viruses, fungi, or parasites. When the body's immune system tries to fight off the infection, it releases chemicals that can damage tissues and organs. This damage can lead to organ failure and death.
Sepsis can be difficult to diagnose because it can mimic other conditions, such as a heart attack or stroke. However, there are some signs and symptoms that may suggest sepsis, including:
- High fever or low body temperature
- Rapid heart rate
- Rapid breathing
- Low blood pressure
- Confusion or disorientation
- Nausea or vomiting
- Diarrhea
- Skin rash
If you experience any of these symptoms, it is important to seek medical attention immediately. Sepsis is a medical emergency and early treatment is essential to improve the chances of survival.
Sepsis is a serious medical condition, but it can be treated if it is caught early. If you think you or someone you know may have sepsis, seek medical attention immediately.
Heart failure
Heart failure is a condition in which the heart is unable to pump enough blood to meet the body's needs. This can be caused by a number of factors, including coronary artery disease, high blood pressure, and diabetes.
- Systolimatic heart failure: This type of heart failure occurs when the heart's contraction (systole) is weak. This can be caused by a number of factors, including coronary artery disease, cardiomyopathy, and arrhythmia.
- Diastolimatic heart failure: This type of heart failure occurs when the heart's relaxation (diastole) is weak. This can be caused by a number of factors, including ischemic heart disease, cardiomyopathy, and pericardial effusion.
- Congestive heart failure: This type of heart failure occurs when the heart is unable to pump enough blood to meet the body's needs. This can be caused by a number of factors, including coronary artery disease, high blood pressure, and diabetes.
- Left-sided heart failure: This type of heart failure occurs when the left ventricle is unable to pump enough blood to meet the body's needs. This can be caused by a number of factors, including coronary artery disease, mitral valve regurgitation, and aortic stenosis.
Heart failure can lead to a number of symptoms, including:
- shortness of breath
- fatigue
- swelling in the feet, ankles, and legs
- difficulty breathing when lying down
- coughing up pink or blood-tinged sputum
- chest pain
- lightheadedness or dizziness
- confusion or disorientation
If you experience any of these symptoms, it is important to seek medical attention immediately.
Can be life-threatening
Dangerously low blood pressure, also known as hypotension, can be life-threatening if not treated promptly. This is because low blood pressure can lead to a number of serious complications, including:
- Stroke: Low blood pressure can reduce blood flow to the brain, which can lead to a stroke. A stroke occurs when blood flow to a part of the brain is interrupted, depriving brain tissue of oxygen and nutrients. This can cause permanent brain damage and disability.
- Heart attack: Low blood pressure can also reduce blood flow to the heart, which can lead to a heart attack. A heart attack occurs when blood flow to a part of the heart is blocked, depriving heart tissue of oxygen and nutrients. This can cause permanent heart damage and disability.
- Kidney failure: Low blood pressure can also reduce blood flow to the kidneys, which can lead to kidney failure. Kidney failure is a condition in which the kidneys are unable to filter waste products and excess fluid from the blood. This can lead to a buildup of toxins in the blood and eventually death.
- Organ damage: Low blood pressure can also lead to damage to other organs, such as the liver, lungs, and intestines. This is because low blood pressure can reduce blood flow to these organs, depriving them of oxygen and nutrients.
In addition to these complications, dangerously low blood pressure can also lead to death. This is because low blood pressure can cause the heart to stop beating or the brain to stop functioning.
If you experience symptoms of dangerously low blood pressure, such as dizziness, fainting, or confusion, it is important to seek medical attention immediately. Early diagnosis and treatment of dangerously low blood pressure can help to prevent serious complications and death.
Causes dizziness, fainting, and nausea
Dangerously low blood pressure, also known as hypotension, can cause a number of symptoms, including dizziness, fainting, and nausea. These symptoms occur because low blood pressure reduces blood flow to the brain and other organs.
Dizziness is a feeling of lightheadedness, unsteadiness, or spinning. It is often caused by a drop in blood pressure, which can reduce blood flow to the brain. Dizziness can also be caused by dehydration, anemia, and certain medications.
Fainting is a temporary loss of consciousness caused by a drop in blood pressure. When blood pressure drops, the brain is deprived of oxygen and nutrients, which can lead to fainting. Fainting can also be caused by dehydration, heatstroke, and certain medical conditions.
Nausea is a feeling of queasiness or an upset stomach. It is often caused by a drop in blood pressure, which can slow down digestion. Nausea can also be caused by motion sickness, food poisoning, and certain medications.
In addition to dizziness, fainting, and nausea, dangerously low blood pressure can also cause other symptoms, such as:
- confusion
- blurred vision
- headache
- cold, clammy skin
- rapid heart rate
- shallow breathing
If you experience any of these symptoms, it is important to seek medical attention immediately. Early diagnosis and treatment of dangerously low blood pressure can help to prevent serious complications and death.
Can lead to organ damage
Dangerously low blood pressure, also known as hypotension, can lead to organ damage if not treated promptly. This is because low blood pressure reduces blood flow to the organs, depriving them of oxygen and nutrients.
Brain damage: Low blood pressure can reduce blood flow to the brain, which can lead to brain damage. Brain damage can cause a number of problems, including memory loss, difficulty speaking, and impaired motor skills.
Heart damage: Low blood pressure can also reduce blood flow to the heart, which can lead to heart damage. Heart damage can cause a number of problems, including chest pain, shortness of breath, and heart failure.
Kidney damage: Low blood pressure can also reduce blood flow to the kidneys, which can lead to kidney damage. Kidney damage can cause a number of problems, including fluid retention, high blood pressure, and kidney failure.
Other organ damage: Low blood pressure can also lead to damage to other organs, such as the liver, lungs, and intestines. This is because low blood pressure can reduce blood flow to these organs, depriving them of oxygen and nutrients.
Organ damage caused by dangerously low blood pressure can be permanent. This is why it is important to seek medical attention immediately if you experience symptoms of dangerously low blood pressure, such as dizziness, fainting, or nausea.
