Can vomiting and diarrhea cause dehydration?

The quick answer is, yes.

When a person experiences vomiting and diarrhea, they lose a large amount of fluid and electrolytes.


Did you know? Dehydration is the biggest health risk associated with dehydration.

An average male can lose up to 3.2 QT (3 L) of fluid during a case of stomach flu*! This loss of fluid and electrolytes causes mild to moderate dehydration.

The key to restoring lost fluid and electrolytes is: clinical hydration


Hydralyte is scientifically formulated to Oral Rehydration Solution. This means it contains the correct balance of glucose and electrolytes for rapid rehydration.

The formulation is based on the World Health Organization (WHO) criteria for effective rehydration.

It is important to note that water or sugary drinks are not as effective as Hydralyte, because they do not restore lost electrolytes (which retain the fluid).
