What Are the Causes of Oliguria in Babies?

Oliguria in children is due to various reasons. The babies will often recover independently, but sometimes medical treatment is required. The causes of oliguria in babies are:

• Dehydration: The major cause of oliguria or decreased urine output is dehydration. Dehydration is caused by vomiting, diarrhea, and decreased intake of water. During this ailment, the kidneys tend to store as much fluid as possible.

• Burns and Any Other Serious Injuries: Burns or any serious injuries cause dehydration resulting in decreased urination and causing oliguria. Any serious injuries resulting in blood loss, septic shock, or anaphylactic shock also result in dehydration, ultimately leading to decreased urine pass in children.

• Obstruction: Any blockage in the urinary tract, like renal stones, causes a disturbance or abnormal passing of urine. The obstruction may be due to any renal stones or tumors obstructing the passage of urine. There are various conditions that cause urinary tract obstruction such as prostate cancer, kidney stones, phimosis, and benign prostatic hyperplasia.

• Kidney diseases: Oliguria is a symptom of kidney failure or kidneys not working properly. Most kidney diseases may result in low urine output in children. Glomerular conditions or other kidney problems lead to oliguria or decreased urine output.
