Ginger ale may help some people feel a little better when they are nauseated, but it is not a proven treatment for nausea. The main benefit may come from taking small sips of fluid, especially if the drink is tolerated well. Ginger itself has better support for easing nausea than ginger ale does.
Many commercial ginger ales contain little or no real ginger. This means they may not provide the same effect seen in studies using ginger capsules, extracts, tea, or other forms with clearer ginger content. Sugar and carbonation can also bother some stomachs, especially if nausea comes with bloating, reflux, or an upset stomach.
If you choose to try ginger ale, take small sips rather than drinking a large amount quickly. It may be most reasonable as a comfort drink or hydration option, not as a medicine. A ginger product that clearly contains real ginger may be more useful than a regular soda.
Seek medical care if nausea is severe, keeps coming back, lasts more than a short time, or comes with dehydration, repeated vomiting, severe pain, fever, pregnancy concerns, or cancer treatment. Do not self-medicate without guidance, especially during pregnancy or while using other treatments.
