Low blood pressure: causes, symptoms, and treatment
About the symptom
Low blood pressure (BP), also known as hypotension, is a condition where the level of blood pressure is significantly below normal. In most cases, normal blood pressure readings range from 90/60 mm Hg to 120/80 mm Hg. When BP falls below 90/60 mm Hg, it can cause a range of unpleasant symptoms. One of the most common manifestations is general weakness and fatigue, which can be particularly pronounced during physical exertion or sudden changes in body position, such as standing up from a seated or lying position.
In addition, patients with low BP often complain of dizziness and fainting, which may be due to inadequate blood supply to the brain. In some cases, hypotension may be accompanied by nausea, vision disturbances, and a feeling of cold sweat. These symptoms arise because a lack of oxygen and nutrients delivered to the organs and tissues can negatively affect overall health. It is important to remember that in cases of persistent or severe symptoms, it is necessary to consult a doctor for diagnosis and appropriate treatment.
Diseases
Low blood pressure, or hypotension, can be not only an independent condition but also a consequence of various diseases. In some cases, low blood pressure may indicate serious disturbances in the body’s functioning that require medical intervention. For example, cardiovascular diseases, endocrine disorders, and some infectious diseases may manifest as a decrease in pressure. Therefore, it is important to carefully monitor your feelings and consult a doctor for diagnosis if necessary.
The most common diseases that can cause low blood pressure include:
- Heart failure
- Arrhythmias (for example, bradycardia)
- Endocrine disorders (hypothyroidism, adrenal insufficiency)
- Sepsis
- Malaria
- Dehydration
- Vitamin and mineral deficiencies (for example, vitamin B12)
If you experience symptoms of low blood pressure, such as dizziness, weakness, or frequent fainting, be sure to consult a specialist to determine the possible causes of this condition and to prescribe the necessary treatment.
Diagnosis
The diagnosis of low blood pressure (BP) is an important step in determining the causes and mechanisms of its occurrence. The doctor typically starts with a thorough collection of medical history, including information about diseases, lifestyle, and symptoms accompanying hypotension. Objective measurement of blood pressure under various conditions, such as at rest and during physical activity, also plays a key role in the diagnosis.
In addition, the doctor may order a number of laboratory and instrumental studies to rule out comorbid diseases or conditions. Thus, a comprehensive approach tailored to the individual characteristics of the patient is often required. This will allow not only to exclude pathological conditions but also to choose effective therapy.
- Complete blood count
- Biochemical blood analysis
- ECG (electrocardiogram)
- Ultrasound of the heart
- Blood pressure monitoring
- Hormone level tests
Which doctor to contact
Low blood pressure (BP), or hypotension, is a condition that requires the attention of medical professionals. It is especially important to see a doctor when experiencing symptoms of low BP, as this may indicate more serious health issues. Initially, it is recommended to visit a therapist who will conduct a general examination and assess your health condition. The therapist may refer you to specialists if more detailed diagnostics and treatment are needed.
Additionally, depending on the symptoms, you may consult a cardiologist if there are suspicions of cardiovascular diseases or a neurologist if neurological symptoms are present, such as dizziness or loss of coordination. It is extremely important to diagnose and treat the underlying cause of hypotension to avoid complications.

Types of Low Blood Pressure
Low blood pressure (BP) can be diverse and classified according to various criteria. One of the main ways to classify it is by the mechanism of occurrence. Primary low BP, also known as idiopathic hypotension, often has no obvious cause and can be related to an individual’s physiology. Secondary low BP occurs against the backdrop of other diseases or conditions, such as cardiovascular pathologies, endocrine disorders, or the consequences of medical treatment.
In addition, low BP can be classified by the degree of its severity. Mild hypotension usually does not require special treatment and may be normal for some people. Pathological hypotension, which leads to serious symptoms, requires careful attention and diagnosis. It is important to remember that different forms of hypotension can manifest in different ways, and correct diagnosis is a key step towards effective treatment.
- Primary (idiopathic) low blood pressure
- Secondary low blood pressure (accompanying diseases)
- Orthostatic hypotension
- Postprandial hypotension (after meals)
- Low pressure associated with medication therapy
Causes of Low Blood Pressure
Low blood pressure (BP) can occur for many reasons, each with its own characteristics. One of the main causes may be genetic predisposition. People with a family history of hypotension are more likely to suffer from low blood pressure. In addition, the physiological characteristics of the body can also play a role: for some people, low BP is a variation of the norm, which does not require treatment or correction.
Disruptions in the cardiovascular system can lead to a significant decrease in blood pressure. This may be associated with heart failure, arrhythmias, or myocarditis. Additionally, persistent low BP may be a consequence of endocrine disorders, such as adrenal hormone deficiency or thyroid dysfunction.
- Dehydration
- Bleeding (internal or external)
- Shock states (anaphylactic shock, septic shock)
- Taking certain medications (antidepressants, painkillers)
- Deficiency of nutrients (B vitamins, especially B12)
- Intense physical activity or stress
Common Related Pathologies
Low blood pressure (BP) can be a symptom of various diseases and conditions, and it is important not to ignore it. One of the most common diseases associated with low BP is orthostatic hypotension. This condition is characterized by a sharp drop in pressure when changing body position, for example, when standing up. It may be accompanied by dizziness, feelings of weakness, and even fainting.
Another cause may be heart failure, where the heart is unable to pump the necessary amount of blood, which also leads to a decrease in pressure. Diseases of the endocrine system, such as hypothyroidism or adrenal insufficiency, can also cause low BP, as they disrupt the balance of hormones that regulate blood pressure. It is important to conduct timely diagnosis and identify related pathologies to avoid serious complications.
- Orthostatic hypotension
- Heart failure
- Hypothyroidism
- Adrenal insufficiency
- Infectious diseases
- Anemia
- Depression and other mental disorders
Expert Opinion
Low blood pressure, or hypotension, is a common problem that can cause many unpleasant symptoms, such as dizziness, weakness, and lethargy. According to experts, it is very important not to ignore these signs, as they may indicate serious disorders in the body’s functioning. Normal blood pressure varies depending on individual characteristics, but a sharp decrease can be a symptom of various diseases or a reaction to stressful situations.
Among the causes of low blood pressure, both physiological and pathological factors are highlighted. Physiological hypotension is more common in people engaged in physical labor or sports, while pathology is usually associated with diseases such as heart failure, endocrine disorders, or infectious diseases. Experts emphasize that for accurate diagnosis and proper treatment, it is essential to consult a specialist who can conduct the necessary examinations and prescribe individual therapy.
Treatment of Low Blood Pressure
The treatment of low blood pressure (BP) depends on the cause of its occurrence and the severity of the patient’s condition. It is important to note that low pressure does not always require medical measures. If low BP does not cause discomfort and is not accompanied by pronounced symptoms, non-surgical methods, such as lifestyle and dietary changes, can be used. For example, increasing salt intake, ensuring adequate hydration, and engaging in regular physical activity can help improve the condition.
If low blood pressure is accompanied by serious symptoms such as fainting, acute dizziness, or weakness, medication may be required. The doctor may prescribe medications that help raise blood pressure or improve the patient’s overall condition. It is important to undergo a complete medical examination to rule out other pathologies that may cause similar symptoms.
- Medications to raise blood pressure
- Diet and lifestyle adjustments
- Physiotherapy procedures
- Monitoring fluid levels in the body
- Psychotherapy to reduce stress
Complications
Low blood pressure (BP), also known as hypotension, can lead to various complications if measures are not taken to correct it. One of the most common complications is fainting, which can occur due to a sudden drop in pressure when changing body positions, such as when standing up. This condition can lead to injuries, particularly in older adults, as falls can be quite serious.
Another potential complication is insufficient blood supply to vital organs, especially the brain and heart. Chronically low BP can cause oxygen deprivation, which can impair the function of these organs. Patients may experience severe fatigue and dizziness, which negatively affects their quality of life.
- Fainting
- Oxygen deficiency in organs
- Fatigue and weakness
- Cardiovascular problems
- Depression and anxiety disorders
