Decreased urine output
Decreased urine output, also known as Oliguria, is a medical condition characterized by the production of less urine than normal. It is often associated with various health issues, including dehydration, kidney disease, and certain medications.
Definition[edit | edit source]
Oliguria is medically defined as a urine output of less than 400 milliliters, which is less than about 13.5 ounces, over the course of 24 hours. The decreased urine output can be a symptom of a variety of health conditions, and it is often one of the first signs of kidney disease.
Causes[edit | edit source]
Decreased urine output can be caused by a variety of factors. These include:
- Dehydration: This is the most common cause of decreased urine output. When the body is dehydrated, it tries to conserve water by producing less urine.
- Kidney disease: Kidney disease can cause decreased urine output because the kidneys are not functioning properly and are unable to filter waste and excess fluids from the blood.
- Medications: Certain medications, such as diuretics, can cause decreased urine output.
- Heart failure: Heart failure can cause decreased urine output because the heart is unable to pump enough blood to the kidneys, which can lead to fluid retention and decreased urine output.
- Urinary tract obstruction: An obstruction in the urinary tract, such as a kidney stone, can cause decreased urine output.
Symptoms[edit | edit source]
In addition to decreased urine output, other symptoms may also be present. These can include:
- Thirst: An increased thirst can be a sign of dehydration, which can cause decreased urine output.
- Swelling: Swelling in the legs, ankles, and feet can be a sign of fluid retention, which can be caused by heart failure or kidney disease.
- Fatigue: Fatigue can be a symptom of kidney disease or heart failure, both of which can cause decreased urine output.
Treatment[edit | edit source]
Treatment for decreased urine output depends on the underlying cause. This can include:
- Rehydration: If dehydration is the cause, rehydration with fluids and electrolytes is the first step in treatment.
- Medication: If a certain medication is the cause, the medication may need to be adjusted or changed.
- Dialysis: If kidney disease is the cause, dialysis may be necessary to filter waste and excess fluids from the blood.
