  • Eat small meals throughout the day instead of the 3 regular meals
  • Eat in a slow and steady manner
  • Avoid foods that are hard to digest
  • Foods that are cold or at room temperature should be eaten in order to avoid being nauseated from the aroma of hot or warm foods

It is also vital to rest after eating. In addition, keep the head in an elevated position at 12 inches above the feet to help reduce nausea.
