Oral rehydration solutions, which contain glucose and electrolytes, are another good way of rehydrating the body if it has lost liquids due to stomach flu.

To make an oral rehydration solution at home, boil 1 liter of water, add half a small spoon of salt and six level small spoons of sugar, and dissolve.

The World Health Organization (WHO) state that this method is most effective at preventing or delaying diarrhea caused by dehydration but that people should not use it as their sole method of treating it.

A great way to include liquids in the diet that give more flavor is to consume healthy teas.

Certain types of tea may also provide extra benefits to a person with stomach flu.

Ginger tea

A recent review found that many studies show the positive effects of ginger tea in reducing nausea. However, the review authors did go on to say that more studies are necessary to confirm this.

Peppermint tea

Another review suggested that, in trials, peppermint tea has also helped many people with nausea, regardless of age.

Although they described this as encouraging, the reviewers did mention that they cannot draw definitive conclusions until they have more evidence from further trials.

A healthy way to introduce non-refined sugar into the diet, as well as rehydrating, is by eating fruits. Fruits contain high percentages of water, and some have a higher percentage than most, including:

The above list includes only raw fruits as solid food. People should be careful when choosing fruit juices to ensure that they do not contain excessive amounts of sugar.

Caring for a child with stomach flu can be worrying for parents and caregivers. Children should have a slightly different treatment plan than adults.

For children, the NIDDK recommend the following oral rehydration solutions as alternatives:

  • Pedialyte
  • Naturalyte
  • Infalyte
