Hello there.
I can understand your concern.
The recordings of blood pressure seem to be normal but i would prefer a recording made by a mercurial blood pressure machine by a physician.
The causes of dizziness need not be restricted to blood pressure drop.
Certain other disorders like low blood
sugar(hypoglycemia), low hemoglobin(anemia) , certain ear and vestibular disorders can also cause this.
Kindly consult a ENT specialist for further help.
Best regards.
