Hi,
I am sorry for the situation your mom is in.
The burning sensation in the mouth and chest she is currently feeling especially after eating is indicative for stomach problems:
- GERD
- gastritis
- ulcer
or cholecyst issues.
I advise to run the following tests to determine the right cause:
- abdominal ultrasound
- upper endoscopy
- complete blood count
- liver/kidney/
pancreas function tests
Meanwhile, I highly recommend to:
- eat often and small portions,
- do chew up slowly
- avoid spicy, chilly, oily, carbonated foods/drinks
- avoid alcohol, coffee, chocolate, etc.
- take OTC antacids after eating
- get her sleep with raised head
Hope it helped!
Dr.Albana
