Heartburn is a common issue during pregnancy due to hormonal changes and the growing uterus pressing against your stomach. To manage heartburn, try eating smaller, more frequent meals instead of large ones. Avoid spicy, fatty, or acidic foods that can trigger heartburn. Staying upright for at least an hour after eating can help, as can sleeping with your head elevated. If over-the-counter antacids don't provide relief, consult your GP for further options. Remember, it's important to address heartburn not only for your comfort but also for your overall well-being during this special time.
