High B P,
( your's B P was 140/90, second time 138/90)
Now coming to your's disease that you want to control B P at 110/70 even without medicines.
A diabetic patient is prone to develop Heart disease, Kidney

Now note down the causes which are responsible for diabetes which is root cause every evil i.e.every disease.
Hectic , hurried life , fast food ,untimely food, fried food, sedentary life, tension , competition (business) , lack of exercises ( no time for exercise) are responsible for 'DIABETES, HYPERTENSION".

90 is a most dangerous B P level at the age of 45 yrs. Lethal B P so at once act.
