High blood pressure is a symptom of something else that isn't working well in the body...doctors need to look for a condtion that causes high blood pressure if
1. the onset of high blood pressure is sudden
2. the high blood pressure is severe (like your Aunt Cindy's)
3. the high blood pressure doesn't respond well to medication
4. the blood pressure was under control but is now going up without any
If your aunt's blood pressure readings fall into one or more of the above categories, then the doctors should be looking at ruling out the following conditions:
chronic kidney disease
coarctation of the aorta
Drug induced hypertension
If the doctors aren't testing for these conditions, you might want to see a blood pressure specialist...an endocrinologist perhaps.
You can read more about these conditions, the tests they use to identify these conditions, and treatment by clicking on the "clock" on the government website below: http://www.nhlbi.nih.gov/guidelines/...n/jncintro.htm
While lifestyle modifications (diet, exercise, etc) and medication may help lower blood pressure sometimes, treatment of the secondary condition may "cure" high blood pressure.
Do lots of reading, ask lots of questions, and take lots of notes....you should familiarize yourself with the tests they do for the above conditions, and know if and when the doctors will be doing those tests, and if they do those tests, what the results are and what the results mean.
