Acid reflux can be more susceptible to the pregnant and obese. The increased levels of hormones during pregnancy and high levels of fats in the body can induce acid reflux because of the pressure in the lower esophageal sphincter, a muscle that prevents the stomach contents from moving back to the esophagus, is reduced. As such, it will be easier for the partially digested contents to come back because less force is holding them back down. In addition, for the pregnant women, the pressure in the abdomen rises due to the developing fetus in the womb.

There are ways to help the body minimize the occurrences of reflux. One of the easiest to implement is positional therapy. This is done by elevating the head and the torso when in a sleeping position. Pillows, which are readily available, can be positioned to raise the torso at about six to eight inches. This position can provide maximum effectiveness in holding back reflux. Surveys have shown that the use of increased recommended elevation results to greater efficiency.
