Why dose my upper stoumic keep rumbling?

Abdominal noises originate from the mechanical churning of the muscular stomach as it moves air swallowed during feeds with ingested foods and gastric juices. Gas created by germs in the small & large intestine can also add to the noise as they move. If this bothers you a change in your diet may help reduce it.

May be reflux (try omeprazole or famotidine) or esophagitis, or food allergies or gluten sensitivity (avoid bread cakes cookies for a week and see if it makes a difference) or even gall bladder .Follow up with gastroenterologist (GI doctor)
