My mother (who is 70) is suffering form Chronic Kidney Disease. She is on meds. She is also diabetic and hypertensive. We inject her insulin and diabetes is under control. Her diastolic blood pressure stays fixed between 60 and 70 but her systolic blood pressure stayed around 160. It sometimes climbed to 180. The doctor told us to increase the Blood pressure medicine. Now the upper blood pressure remains between 140 and 160. (It's either 140 or 160). The nephrologist says it's fine. Since last two days, we have included garlic in her food. Are we on the right path? What else should we do to bring the blood pressure down to 130 to avoid any further long-term damages?
