Your mother symptoms are related to depression
. Depression can manifest with not only psychological symptoms but with a variety of physical symptoms also like: IBS
like symptoms, dyspepsia
and medically unexplained somatic symptoms etc.
There is no way by which gas can transferred from abdomen to head, but we used to see similar complaints from depressed patients. It is better to get evaluated by psychiatrist
for depression and start treatment accordingly.
For long term control of depression following measures are helpful: relaxation exercise, medicines like SSRIs and non drug treatment like CBT.
Wish you all the best.
