Triggers vary across individuals, but common ones include large meals, late-night eating, fried or high-fat foods, chocolate, mint, alcohol, carbonated drinks, tomato-based sauces, spicy foods, and certain coffee preparations. Excess body weight, tight clothing, frequent bending, and lying down soon after meals increase intra-abdominal pressure and can worsen symptoms. Smoking can reduce lower esophageal sphincter (LES) tone and intensify reflux. The most effective strategy is not a universal “ban list,” but data-driven personalization: keep a 7–10 day symptom diary and test triggers one at a time. If nighttime symptoms dominate, optimizing meal timing and sleep position typically provides the highest return on effort.
