HI, thanks for using healthcare magic
High blood pressure
is most often primary -there is no obvious disease causing the blood pressure, mainly associated with age, family history of high blood pressure, diet, physical activity, risk factors such as smoking
It is extremely important that the blood pressure be controlled because of the complications.
Treatment includes: (1)restriction of salt intake, (2) use of fruits and vegetables, (3)restriction of use of juices, carbonated beverages,alcohol (4)use of low fat foods such as low fat cheese, low fat milk (5)use of foods that contain potassium and calcium which have been shown to improve blood pressure.
In addition , it is important that your wife takes her medication as prescribed.
I hope this helps
