1、 Metabolic characteristics of sucralose
Not metabolized and broken down by the human body
Sucralose, due to its molecular structure containing chlorine atoms (chlorinated sucrose derivatives), lacks enzymes in the human body to break down its chemical bonds, making it unable to be absorbed and metabolized by the digestive system. After oral administration, about 85% is directly excreted through feces, and 15% is excreted through urine, without participating in energy metabolism throughout the process.

Not causing intestinal fermentation
Unlike sugar alcohol sweeteners such as sorbitol and xylitol, sucralose is not fermented by intestinal bacteria and does not produce gases such as carbon dioxide and methane, so it does not cause bloating or increased exhaust.

2、 Possible reasons for bloating after drinking beverages containing sucralose
If there is an increase in exhaust after drinking sugar substitute drinks, it may be related to the following factors:

Compound with other gas producing components

Sugar alcohols such as erythritol and maltitol may also be added to beverages, which are fermented by bacteria in the colon to produce gas and cause bloating.
Dietary fiber (such as inulin) may also be fermented to produce gas.
Carbonated gas action
The carbon dioxide in carbonated beverages can directly cause gastrointestinal bloating, regardless of sweeteners.

Individual sensitivity differences
Part of the population's gut microbiota is sensitive to artificial sweeteners, which may indirectly affect digestive function, but this effect is not related to direct fermentation of sucralose
