What happens to the body when a person consumes fizzy drinks?
When a person consumes fizzy drinks, the carbonation turns into carbon dioxide which creates a tingling sensation, according to dietician Ekta Singhwal. This carbon dioxide then warms up in the stomach, sometimes causing belching and heartburn, Singhwal said. She added that the drinks' high sugar content leads to a spike in blood sugar, often followed by an energy crash.
