Hello. WELCOME TO HCM.
What your mother is undergoing does not seem to be an organic problem. At her age, indigestion
is a common problem and can result in loud belching
. Lot of patience and care is required in dealing with such old people and they also require to be nurtured just like small children. The feaar of impending reality of life: DEATH is disturbing for everybody at that age. Often they will feel that everybody is busy and they are lacking our attention. So, there comes a component of attention seeking behavior also.
Make sure that you spend some time- relaxing with her and talking about everything- be it television/ life/ food/ old memories etc. try to explain to her- how important it is for her to eat right kind of food (fruits etc, based on other coexisting conditions- diabetes
.). Also assure her that she has support of everybody. Hope that should help you.
