Hi Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
yes low Blood pressure can cause symptoms like
dizziness, headache, fatigue,
loss of consciousness etc. As your blood pressure was 97/53, this was most probable cause of
headaches and dizziness in you.
Low blood pressure is commonly caused by low blood volume as in blood loss from hemorrhage, insufficient fluid intake, excessive fluid losses from
diarrhea or
vomiting, excessive use of diuretics,etc.
Low blood pressure could also be caused due to some heart problem, due to some medicines such as diuretics, BP lowering medicines also. First of all you should increase fluid & salt intake. take a strong cup of coffee also helps to increase blood pressure a bit.
If problem still persists, visit a physician
Hope your query is solved
