Many people find that using soda for an upset stomach is very helpful. Sodas used for an upset stomach typically include cola or ginger ale, though some people also drink clear sodas as well. There are arguments for and against using soda for an upset stomach; in most cases, if you find it to be helpful, and only use it every once in a while it is probably fine. It is best to stir the carbonation out of the soda first, because the carbonation can cause bloating and gas and actually make nausea worse.

Most people sip on soda to combat feelings of nausea or indigestion. Ginger has been used for many years to combat nausea, and while ginger ale can be used as soda for an upset stomach, there are other methods as well. Ginger pills or even chewing on a bit of fresh ginger can have the same effect. In cola soda, it is the cola syrup that can help to relieve nausea. Finally, clear sodas may not have any true effect on nausea, but some people prefer to sip them anyway.

The sugar in the sodas can sometimes help to boost blood sugar and help with nausea as well. Pregnant women often sip on ginger ale for this reason, because it is caffeine free. As you can see, using flat soda for an upset stomach can be an effective method of relieving mild nausea. In general, though, experts do not recommend using soda for rehydrating purposes after or during an actual illness that causes vomiting and potential dehydration.

This is because the sodas are extremely high in sugar but do not do anything to replace electrolytes. Watered down sports drinks or electrolyte drinks for children are a much better choice when attempting to prevent dehydration. Decaffeinated peppermint tea may be a good choice as well. Some people find that lemonade can be good for rehydration purposes on a hot day, if one begins to feel slightly dizzy or nauseous; this is not recommended after a stomach illness, however.

Drinking plain water can be a little hard on an upset stomach, but in normal cases, it is important to drink enough water every day to stay hydrated. Preventing dehydration in the first place is a good way to prevent an upset stomach. Keep in mind that while an occasional upset stomach is normal, you should not need to constantly use soda for an upset stomach; if you are frequently nauseous without any identifiable cause, it may be a good idea to visit a doctor.
