Hello dear,welcome to HealthcareMagic forum.
I am Dr Aslam here to help you
Your BP is too low for your age.If not getting corrected in few days of adequate rest,fluids,and healthy diet,this definitely needs a detailed evaluation to find out the underlying cause.
All your symptoms can be caused by
hypotension itself,with contribution from the underlying cause.
As you have history of gastric ulcer,you are at increased risk of
anemia also.If this is the case,correction of anemia and management of ulcer might correct the BP.
Kindly see your doctor for detailed evaluation and management.
Wishing you good health,Thank you.
