whatever you have mentioned shows that your mother is having all the symptoms of hypertension
. Whatever medicines your doctor has prescribed are right. The reason behind giving antidepressants is making her calm down. In women in old age considering menopause
and other health complaits the chances of getting anxious are more which in turn worsens the existing complaints.
With these medicines she will get peaceful sleep and her anxiety
will come down and because of better sleep her acidity problems too will reduce.
Along with the medicines let her break the meal and consume it every 2hrs. That will help her reduce the gastric complaints.
will help her regain her freshness and will be good for her heart health.
I hope this answers your question.
Wish you good health.
