hi,thanks for query.In spite of treatment from eight months,her blood pressure is not normal.Please talk to your doctor and discuss with him about option of increasing the dose or changing the drug.Ask her to take law salt in diet,do regular exercise and plan her diet well.Please watch her weight and try to maintain near normal weight.If not done please go for some routine blood reports like lipid profile
and liver reports,EKG etc.Ask to her to practice relaxation techniques
like yoga and meditation
this will definitely help.
wishing her good health.
