My stomach rumbles a lot, especially during office meetings! is there anything i can do to stop it from rumbling, besides eating?

Yes: If this often occurs during stress it is likely irritable bowel. There are medications which can be helpful. Also, peppermint oil or tea may help. Avoid caffeine, sodas, and drinking out of narrow mouth bottles (water bottles) and with straws.

Antispasmodic: Your physician can prescribe an antispasmodic medication like dicyclomine which quiets intestinal activity. Take it 1/2 hour before the meeting. Dryness of the mouth is a side effect.
