The objective of treatment is to replace fluids and electrolytes (salt and minerals) lost by diarrhea. Blood transfusions are rarely required.

Antibiotic or antimicrobial therapy is usually not indicated unless the rest of the body is affected. Ask your doctor before using any antidiarrheal medicines.

Self-care measures to avoid dehydration include drinking electrolyte solutions to replace fluids lost by diarrhea, and eating no solid food until the diarrhea has passed. People with diarrhea, especially young children, who are unable to drink fluids due to nausea may need medical attention and intravenous fluids. People taking diuretics ("water pills") need to be cautious with diarrhea and may need to stop taking the medication during an acute episode, as directed by the health care provider.

With most infections, symptoms improve with fluid and electrolyte replacement within a week. There are rare cases of patients with renal failure and even death due to the infection.

• Systemic infection
• Dehydration
• Anemia (low blood counts)
• Kidney failure (rare)
• Arthritis
• New onset of irritable bowel syndrome

Call for an appointment with your health care provider if diarrhea recurs or persists for more than a week, or if there is blood in stools. Infants and young children become dehydrated more rapidly than adults. Call your provider if your child develops any signs of dehydration, even if it is only a few hours since the onset of illness.
