Stomach issues worsening when lying down often involve acid reflux/GERD, where acid comes up into the esophagus, and conditions like ulcers, IBS, IBD, and gallstones, as lying flat lets acid flow back and gravity stops helping digestion, increasing irritation or pressure. Lying down after a large meal, bloating, and inflammation from conditions like Crohn's or pancreatitis can intensify pain, while some relief might come from positions like leaning forward or bringing knees to chest.
