Can chewing gum during prepration of egd and colonoscopy effect test in anyway?

Chewing Gum before an esophagogastroduodenoscopy (EGD) and colonoscopy can affect the tests. It may stimulate saliva production and gastric secretions, potentially leading to false results during the EGD. For colonoscopy, chewing gum could result in residual food or air in the digestive tract, complicating visualization. Therefore, it's generally advised to avoid chewing gum before these procedures.
