Those individuals who suffer from chronic, frequent heartburn may have a more serious condition called gastroesophageal reflux disease, or GERD. Heartburn is the most common symptom of GERD, though there are some individuals who have been diagnosed with GERD who do not have symptoms of heartburn. Other symptoms of GERD can be the feeling of a lump in the throat, hoarseness, or a dry cough.
Approximately 50 percent of pregnant women will experience heartburn, especially during the last trimester of pregnancy.
