My mother is 84 years old, the past few months she vomits almost every evening. It seems she is not digesting her food. Last week she had just finished lunch and we noticed she was quiet, but in fact she was staring straight ahead, not breathing and not responding to us yelling. lasted about 2 minutes, then she vomited, and voided. We called an ambulance, they determined it wasn t her heart or a stroke. They felt it was her blood pressure was too low. She is otherwise not on any medication other than relaxofene (treatment for osteoporosis).
