Thanks for asking. It's very common complain during pregnancy due to hormonal affect. Her symptoms suggested GERD and may be with gastric ulcer disease. Advice: avoid snacks, spicy and junk foods, heavy meal. Intake meals in time and in small divided amount. Not to go bed just after meal and maintain 1-2hrs gap in between. It's better to make 15°angle of the bed for lying in 15° propped up position. Intake green leafy vegetables, raw fresh seasonal fruits adequately. Practice Meditation it makes the mind cool and culm which is also a significant factor for much acid secretion. If not respond then medication according to gestational age.
