Oliguria: Causes, Symptoms, and Treatment of this Condition
About the Symptom
Oliguria is a medical term that refers to a condition in which the volume of urine produced is significantly below normal. Typically, an individual excretes about 800-2000 ml of urine per day, but in cases of oliguria, this volume may be less than 400 ml. This condition can be a worrying signal of possible disorders in the body and requires careful examination by specialists. Oliguria may indicate kidney insufficiency, dehydration, or other serious illnesses, so it is crucial not to ignore its manifestations.
The symptoms of oliguria may vary depending on the underlying cause. In most cases, patients may notice not only a reduction in urine volume but also possible swelling, fatigue, headache, and other uncomfortable sensations. Oliguria is often accompanied by other symptoms such as thirst or dry mouth, indicating a deficiency of fluids in the body. If you notice such manifestations, it is recommended to consult a doctor for diagnosis and to determine the exact cause of this condition.
Diseases
Oliguria, defined as decreased urine production, can be a manifestation of various diseases and conditions that require medical intervention. It is often associated with disorders affecting kidney function, as well as other pathological states that may cause obstructions in the urinary tract. Proper diagnosis of the diseases leading to oliguria plays a key role in treatment and the restoration of normal urinary system function.
Among the diseases that can cause symptoms of oliguria, the following can be highlighted:
- Acute kidney failure
- Chronic kidney failure
- Urinary tract obstruction (e.g., kidney stones)
- Ureteral stenosis
- Diabetes mellitus (and its complications)
- Hypovolemia (decreased blood volume)
- Severe infection or sepsis
- Cardiovascular diseases leading to decreased blood flow to the kidneys
Each of these diseases can have serious health consequences, so it is important to promptly consult specialists for diagnosis and possible treatment if you notice a decrease in urine output.
Diagnosis
Oliguria is a condition characterized by a decrease in the volume of urine produced by the body to less than 400 ml per day. For the correct diagnosis of oliguria, it is important to determine its cause, as it can be a sign of various diseases. The doctor begins with a thorough history taking, including information about other symptoms, medications taken, and underlying conditions. This is followed by a physical examination, which may reveal some accompanying issues.
The main diagnostic procedures to confirm oliguria may include laboratory tests and instrumental studies. These include a urinalysis, a complete blood count, a biochemical blood test, as well as an ultrasound of the kidneys and bladder. These methods help determine whether the patient has signs of renal failure, infectious diseases, or other pathologies contributing to oliguria.
- Urinalysis
- Biochemical blood test
- Ultrasound of the kidneys and bladder
- CT or MRI of the pelvic organs
- Cystoscopy (in some cases)
Which doctor to contact

Types of Oliguria
Oliguria, characterized by a decrease in the volume of urine output, can manifest in several forms, each with its own causes and clinical features. The main types of oliguria include drug-induced, physiological, and pathological oliguria. Drug-induced oliguria occurs as a result of taking certain medications that can affect kidney function and, consequently, the level of urine production.
Physiological oliguria may occur under conditions of increased fluid loss in the body, for example, during intense physical activity or high temperature. Pathological oliguria, in turn, is associated with diseases affecting the kidneys or the urinary tract. Understanding the different types of oliguria is crucial for diagnosis and the choice of appropriate treatment.
- Drug-induced oliguria
- Physiological oliguria
- Pathological oliguria
Causes of Oliguria
Oliguria, characterized by a decreased urine volume, can arise from various reasons, and its diagnosis requires the attention of a specialist. First of all, it should be noted that oliguria can be caused by dehydration of the body, for example, due to significant fluid loss as a result of hot weather, intense physical exertion, or insufficient water intake. Thus, in these cases, correction of water balance is necessary to normalize urine output.
Other common causes of oliguria include kidney diseases that can hinder the normal filtration process. For example, infectious kidney diseases such as pyelonephritis or glomerulonephritis can cause inflammation and disrupt the function of the organs. Chronic diseases such as diabetes or hypertension can also be risk factors for the development of oliguria. It is important to note that some medications, particularly diuretics, can have an accompanying effect on reducing urine volume, especially with changes in dosing regimen.
- Dehydration
- Kidney infections (pyelonephritis, glomerulonephritis)
- Chronic diseases (diabetes, hypertension)
- Side effects of medications
- Cardiovascular diseases
Common Related Pathologies
Oliguria, characterized by a decrease in urine output, can be associated with a number of diseases and pathological conditions. One of the most common causes of oliguria is acute kidney injury, which can occur as a result of infection, trauma, or exposure to toxic substances. Pathologies such as glomerulonephritis and pyelonephritis can also affect normal kidney function and reduce the volume of urine produced. Additionally, nephrotic syndrome, which is accompanied by protein loss in urine, can cause oliguria due to a disruption in the body’s water-electrolyte balance.
It is also worth noting that oliguria can be a consequence of cardiovascular diseases, such as heart failure. In such conditions, there is a decrease in blood flow to the kidneys, which in turn slows their function and leads to decreased urine production. Other related pathologies include diseases of the urinary tract, such as obstructions caused by kidney stones, which can lead to almost complete cessation of urine output or significant reduction in it.
- Acute nephritis
- Pyelonephritis
- Nephrotic syndrome
- Chronic heart failure
- Urinary tract obstructions
- Kidney injuries
- Toxic kidney damage
Expert Opinion
Oliguria, characterized by a decrease in urine volume, is a serious symptom that requires the attention of medical professionals. As noted by a leading nephrologist, it is important to understand that oliguria can be not only a consequence of an acute disorder but also a sign of a deeper pathology that requires a comprehensive approach to diagnosis and treatment. A decrease in urine production can signal various ailments, ranging from temporary kidney failure to severe disorders in the cardiovascular system.
