Hello I really appreciate your concern Looking at history this could be regurgitated stomach content in the food pipe ( oesophagus) Another possibility is zenkers diverticula which develops due to weakness of a muscle of neck wall leading to formation if pouch which may collect the regurgitated food content and produces gurgling sounds please visit your doctor for detailed examination You can minimise acid reflux by adopting few life style modifications like don t lie down immediately after food avoid alcohol and smoking avoid fatty fried and spicy food or carbonated drinks you can take PPI group of drugs like omeprazole and antacids Hope this answers your question Wishing you good health
