Im 24 years old and i have 90/60 blood pressure..is it normal?

It can be normal.: A blood pressure less than 100/70 can be normal for some people. If it is too low, symptoms develop of dizziness, fatigue, weakness and black spots in the vision when standing from a sitting position. If you feel well and can do normal activities, including standing and immediately walking, the blood pressure may be normal for you. If symptomatic, check dehydration or adrenal disease.
