I would not recommend changing BP medications every 3-4 months just to prevent the onset of potential side-effects, but it certainly makes sense to reassess how you are doing on a BP med after a certain interval (usually after a few weeks, and then every few months or more often if the dose still needs to be refined or if there is concern about potential side-effects).
What these scientists found was that while drug treatments for mild hypertension may be effective at lowering blood pressure, they were not effective in reducing overall mortality. Put more bluntly, hypertension patients in these studies died at about the same rate whether they took medication or not. These findings reaffirm an important health principle: Treating the symptoms of disease is not the same thing as causing health.
Such monitoring provides excellent information for patients and doctors. In fact, research shows that ABPM is a better predictor of future cardiovascular events (e.g. heart attacks, strokes) than conventional office-based BP measurements are. However, ABPM is not yet widely available, since it requires special equipment and may not be covered by insurance.
Kiwis are another fruit that positively impacts blood pressure. Some researchers studied how the fruit fares compared to apples. They found that eating three kiwis a day over eight weeks reduced blood pressure in people with slightly high blood pressure more so than eating one apple per day during the same time. A daily serving of kiwi was also found to reduce blood pressure in people with only mildly elevated levels. Kiwis are also an excellent source of vitamin C which can also also improve blood pressure.
