Being overweight means you can be more likely to suffer from reflux because of increased pressure on your stomach, which can force open the valve after a meal.
Some people find acid reflux is worse when they are stressed.
Acid reflux also happens due to a weakness of the sphincter muscle, or when the stomach produces too much acid and not enough protective mucous. There is also something called a hiatus hernia; due to a gap in the diaphragm, parts of the stomach can move into the chest which increases the risk of reflux.
Taking pain relievers such as ibuprofen, some muscle relaxers, or blood pressure medications can also stimulate acid reflux.
