Complications

By Mayo Clinic staff

Dehydration — a severe loss of water and essential salts and minerals — is the most common serious complication of gastroenteritis. If you're a healthy adult and drink enough to replace fluids you lose from vomiting and diarrhea, dehydration shouldn't be a problem.

But infants, older adults and people with suppressed immune systems may become severely dehydrated when they lose more fluids than they can replace. In that case, they may need to be hospitalized and receive intravenous fluids. In extreme cases dehydration can be fatal.
