Hemolytic Uremic Syndrome

Definition

Hemolytic-uremic syndrome (HUS) is a disorder that usually occurs when an infection in the digestive system produces toxic substances that destroy red blood cells. It often affects the kidneys.

Symptoms

HUS often begins with vomiting and diarrhea, which may be bloody. Within a week, the person may become weak and irritable. Persons with this condition may urinate far less than normal. Urine output may almost stop.

Red blood cell destruction leads to symptoms of anemia.

Early symptoms:

• Blood in the stools
• Irritability
• Fever
• Lethargy
• Vomiting and diarrhea
• Weakness

• Bruising
• Decreased consciousness
• Low urine output
• No urine output
• Paleness
• Seizures -- rare
