Many people reach for a carbonated beverage, often called “pop” or “soda,” as a common home remedy for nausea. This widespread belief suggests the sugary, fizzy drink offers a quick solution to an unsettling feeling. While the practice has been passed down through generations, it is important to investigate whether this folk remedy is based on science or simply tradition.
The Role of Carbonation and Sugar
The temporary relief felt from drinking a carbonated beverage is usually attributed to the carbon dioxide gas. The bubbles encourage belching, which helps release trapped gas and relieves feelings of uncomfortable pressure or fullness. This mechanical action provides a momentary sense of relief, making the drink seem effective against nausea. However, this relief is often short-lived and does not address the underlying cause of the discomfort.
The high concentration of sugar in most soft drinks can actively work against calming an upset digestive system. A sudden influx of a sugary solution triggers an osmotic effect, drawing water from the body into the digestive tract to dilute the sugar. This process can potentially worsen nausea and exacerbate dehydration. While sugar may offer a brief energy boost, the overall impact on fluid balance is counterproductive to recovery.
Distinguishing Real Ginger from Soda Ingredients
The most commonly recommended soft drink for an upset stomach is ginger ale, based on the historical use of ginger as a natural anti-nausea treatment. Real ginger root contains compounds called gingerols, which possess proven anti-inflammatory and anti-nausea properties. These gingerols regulate gastrointestinal motility, encouraging the efficient movement of food through the digestive tract. This is the scientific basis for using ginger to manage nausea associated with conditions like chemotherapy and morning sickness.
The problem is that most commercial ginger ale brands contain minimal to no actual ginger root extract. Mass-produced sodas rely instead on artificial flavoring, which lacks the therapeutic concentration of gingerols needed for genuine relief. One major brand even settled a lawsuit over claims it was “made with real ginger,” despite independent testing finding no detectable ginger compounds. Therefore, relying on typical store-bought ginger ale for medicinal benefit is ineffective, offering little more than carbonated water and sugar.
Recommended Approaches for Calming the Stomach
A reliable approach to managing nausea involves focusing on gentle rehydration and bland foods. Sipping clear, non-caffeinated liquids, such as plain water, weak tea, or clear broths, prevents dehydration without irritating the stomach. Electrolyte solutions are particularly helpful, as they replace sodium and potassium lost through vomiting or diarrhea, aiding in the restoration of fluid balance. Small, frequent sips are better than drinking large amounts at once, which can trigger more vomiting.
When a person feels ready to eat, bland, easily digestible foods should be introduced gradually. Items like bananas, rice, applesauce, and toast are recommended because they are low in fat and fiber, making them easy on the digestive system. Avoiding spicy, greasy, or strong-smelling foods is wise, as these can easily re-trigger sickness. Other simple comfort measures include deep, slow breathing exercises or consuming small amounts of peppermint, which can have a soothing effect on the stomach lining.
