Ur blood pressure is in pre hypertension range. As age progress, BP will change. The most impressive thing is here to adopt lifestyle modification, i.e, do some physical activity, restricts salt intake and fried/ oily food. Eat more of vegetables and fruits., if u any habit then avoid it and be happy or stress free.
As ur blood parameters are normal, so there is no underlying cause of hypertension
