Eating only one meal a day actually slows digestion and worsens bloating and nausea. Long gaps between meals make your stomach empty more slowly, and this pattern is called delayed gastric emptying when it continues.
Next Steps
Try eating 3 smaller meals plus a light snack or two instead of one big meal, and eat slowly without rushing. Avoid lying down right after eating. If the bloating and pukish feeling continue beyond two weeks, see a gastroenterologist to rule out H. pylori or a motility problem.
Health Tips
See a doctor sooner if you notice unintended weight loss, vomiting blood, or ongoing pain.
