I have always had high pressure and i dont know why,any reason.today was 162/113?what are main reasons for constant high pressure,

Need treatment!: If iyou always have high blood pressure, you need to be treated. It will vary, and could be higher at times than others. Avoid alcohol, caffeine, and over the counter meds that say not to take if you have high blood pressure Decrease salt, lose weigh, stop smoking. Every day your blood pressure is not controlled you risk damage to your organs at some point. Get seen this week.

Second.Hypertention: At 25 years, you seem too young for usual causes of hypertension like hardening of arteries etc. Pl get yourself evaluated by your PCP for your kidney functions for conditions like renal artery disease or Pheochromocytoma etc. Pl see attached for further info. Hope you feel better, soon:)
