Suggest Treatment For Indigestion

Hi, this is Srikanth from India my mom is suffering from indigestion...Actually during last April (i.e. April 2011) she had major illness related to brain. So, we had taken her to a doctor named G S P Raju who is a famous Psychiatrist in our home town. Since then she is regularly visiting the same doctor and based on her condition the doctor is used to change the medicine. Till last week there is no complaint regarding digestion.
Since last week she is saying that she is suffering with indigestion. So we have taken her to a General physician and told him and shown him the medicines which my mom is using at present. as per him, using these tablets will cause the liver to shrink causing indigestion. He has given few tablets. But my mom was unable to take them.Please guide us or show us a way how can we help my mom to overcome this situation.
