We created this animation for Gavison to show how Gaviscon can work in a complementary way to medication such as PPIs (proton pump inhibitors). Reflux events are caused by the Lower Oesophageal Sphincter (LES) failing to close fully, which allows stomach acid to enter the oesophagus. This causes burning in the oesophagus, and the vapours can condense at the back of the throat giving an acidic taste. PPIs reduce stomach acidity, but some symptoms can persist because the LES is still weak, and patients can experience irritation in the oesophagus (particularly if it’s already damaged from previous reflux events). Gaviscon works to soothe the damaged oesophagus, and the Gaviscon raft physically blocks the acid reflux, removing the associated symptoms.
