Prenatal Vitamins

• Taking prenatal vitamins may irritate your throat and stomach and cause you to have acid reflux.
  
  

Hormones

• Pregnancy hormones can relax your muscles, including the ones in your esophagus that otherwise prevent stomach acid from leaking out and causing reflux.
  
  

Foods

• Your food cravings during pregnancy may cause acid reflux, especially if you eat greasy, fatty or spicy foods.
  
  

Caffeine

• Although you may not be drinking coffee while pregnant, the caffeine in chocolate, hot cocoa and black tea may cause you to have acid reflux.
  
  

Eating Too Much

• During pregnancy, the capacity of your stomach is smaller and acid reflux may result from eating too much at once.
  
  

Fetal Position

• The position of your baby may trigger your acid reflux, especially once your baby turns head down and the feet push into your ribs.
  
  

Uterine Growth

• As your uterus gets larger in the last few months of pregnancy, it pushes your other internal organs into a smaller amount of space, resulting in acid reflux.
