Been having bacon burps without eating bacon. bloated & constipated too. any idea why please?

IBS?: Burps that taste like bacon can occur a long time, several hours, after eating bacon and after eating other meat, not just bacon. The sulfur and fat likely contribute and may have an effect on the bloating and constipation, too. Likely this is a manifestation of irritable bowel syndrome. Increase water intake, fiber in diet, possibly psyllium supplements, and exercise. Good wishes:)
