Complications

Because you lose vital fluids, salts and minerals during a bout with traveler's diarrhea, you may become dehydrated, especially during the summer months. Dehydration is especially dangerous for children, older adults and people with weakened immune systems.

Dehydration caused by diarrhea can cause serious complications, including organ damage, shock or coma. Signs and symptoms of dehydration include a very dry mouth, intense thirst, little or no urination, dizziness, or extreme weakness.
