question: My mother has pancreatic cancer and is being treated palliatively (ie., has a metal stent; pain relief - fentanyl patch + endone for breakthough; and has just commenced on dexamethasone). Her stomach is constantly grumbling (which you can hear from quite a distance + easily feel when you lay your hand on her abdomen) and she has a lot of wind, primarily flatulence but some burping.  Is there anything that might help with these symptoms as they cause her some distress?
