I have GERD and sliding Hiatal Hernia. I have been taking 150mg of Zantac twice a day. I have just found out that I am pregnant. Dear Tammy, Gastroesophageal reflux is a very common disorder, but as you pointed out it is much more common during pregnancy.
Pregnant women have the highest incidence of daily heartburn.
This is due to increased progesterone levels during pregnancy and due to mechanical factors that put pressure on the stomach as the fetus grows. The hormone progesterone decreases lower esophageal sphincter pressure thus allowing for gastroesophageal reflux to occur. If possible, pregnant patients should avoid taking all medications unless absolutely necessary. Antacids are also considered safe during pregnancy. I hope you find this information helpful.
