Hello
These symptoms , as you mentioned in the query is very common among female ( or even in male ) near about 60 years age .
The reason of such symptoms are :
1 Over eating , tension ,
stress , untimely feed.
2 Hyper acidity or
gastritis . Try raising the head of your mother's bed about 4 inches with blocks. It might also help to avoid eating or drinking for 2 hours before she lie down.
To help control stomach hyper acidity one should not drink excessive tea , coffee or chocolates, sweets , spicy , greasy food , pizza, burger.
Also give her some
antacid ( if it contains oxetacaine it will be better ) . But if there is severe gas formation she may need some ENZYME preparation + pantoprazole-d tablet according to severity of symptoms.
3 In adequate sleep in the night is also a predisposing reason of such gas formation.
In my opinion , at present there is no need of any consultation . With the help of these measures your mother will be fine, I hope so.
