What causes bile reflux?

Bile reflux is most commonly caused by a problem with the pyloric valve that’s supposed to keep bile from escaping into your stomach. This might be a result of:

• Surgery, especially stomach surgery and gallbladder removal surgery.
• Obstruction of the pyloric valve by a duodenal ulcer or scar tissue.
• Impaired motility, delaying the functioning of the pyloric valve and the downward flow of bile.
