A 23-year-old pregnant female who is 30 weeks gestation presents to her physician for a routine prenatal examination. Her blood pressure and laboratory results all are normal and ultrasound reveals the fetus to be in good health. She also indicates she is eating a very healthy diet high in lean proteins and complex carbohydrates while taking her prenatal vitamins as prescribed. However, she complains that she has recently been woken up at night or during naps by a burning sensation in her chest. She says she has never experienced this before and antacids have seemed to provide some immediate but short-lived relief. She goes on to indicate that this sensation only occurs at night. Based upon this information, what is the most likely cause of her symptoms?
