It doesn't take much imagination to figure out that this is a game changer in health monitoring-or that it might create a legion of e-hypochondriacs or cyberchondriacs. While many individuals who surf the Web start believing they may have the diseases they are reading about, continuous monitoring of one's vital signs takes this concern to a new level. Nevertheless, the upside of having such information available is considerable. We know that people who weigh themselves each day rather than once per week are more successful at losing weight and maintaining their weight. Similarly, mobile phone apps that count calories have facilitated weight loss for some people.
Telemonitoring of blood pressure, likewise, has been shown to have a positive impact on management. We also know that controlling blood pressure and especially avoiding marked shifts or variability are central to reducing the risk of stroke and heart attacks. Remote monitoring also avoids "white coat hypertension"-elevated blood pressure brought on by anxiety about a doctor's appointment. Such data can provide the best guidance for titrating medications, helping reveal the right doses of the right drugs for the right patient. It can also help a patient discern how changes in diet, such as a high salt load, and exercise can affect the blood pressure.
You really need to read this whole post, which is the first I've seen to extend the benefits of telemonitoring beyond a purely medical setting.
