amato
I drastically decreased the amount of gas I had, by taking for a month digestive enzymes and olive leaf extract.
It's really soothing.Get her try it.
But remember, don't give her an enzyme that contains too much protease.Select a brand that contains mostly lipase and amylase(a little protease doesn't hurt though)
If you live in the north hemisphere and it's cold, keep here as warm as possible.UC hates cold(personal experience)
Also for gas she can take activated charcoal, no more than 3 days in a raw(otherwise mineral deficiencies will arise).
gas is sometimes worse with: cabbage, broccoli, beans, alcohol, milk
also doing some light exercise may help with gas(let her not overdo it though)
good luck
