Oliguria

Oliguria is a medical term that describes when someone produces less urine than usual, typically less than 400 milliliters per day in adults. It can be a sign that the kidneys are not working properly or that the body is conserving fluids due to dehydration, blood loss, or other illnesses. Oliguria may be temporary or indicate a more serious condition requiring medical attention. Monitoring urine output can help healthcare providers assess a person's fluid balance and kidney health to determine the cause and appropriate treatment.
