What Is Giardiasis?
Reviewed: Dr. Gromatzky
9. Prognosis
With or without treatment, most people recover from giardiasis with no lasting ill effects. However, some people exhibit chronic symptoms of giardiasis following an infection. The reasons for this are not entirely clear. It may be due to bacterial overgrowth of the small intestine or postinfectious irritable bowel syndrome.
The dehydration that may result from severe diarrhea due to giardiasis can be especially dangerous for pregnant women and young children. Although giardiasis is rarely fatal in adults, infants who become dehydrated due to giardiasis can die as a result.
