[QUOTE="Brunneria, post: 1031244, member: 41816"] The three best ways that I know to diagnose RH are: A 5 hour GTT (2 hours won't show it for most RHers) A GTT followed by a 72 hr fast ([USER=85785]@nosher8355[/USER] has done this, so can tell you more) Using a Freestyle Libre for a few days (this one is only something I discovered very recently when I [URL='http://www.diabetes.co.uk/forum/threads/freestyle-libre-teaching-me-sooo-much-about-my-t2-and-rh.89347/']got the Libre and saw my RH very clearly[/URL]. The libre isn't available on the NHS) My view is that in order to identify RH you need blood glucose tests every 15 mins during a GTT, certainly for the first hour or two, because RHers tend to shoot up very high, very fast, and a test at 2 hours simply won't spot that, because they may be back down to normal by then. Then the test needs to be much longer than 2 hours to catch the drop when it happens. But it is very individual when that happens. Could be 90 mins, could be 5 hours. With me, it depends on a lot of things - how much carb was eaten, how much fat and fibre were eaten alongside (which doesn't happen in a GTT), also stress and physical activity levels. All these factors make it almost impossible for a doctor to even [I][B]see[/B][/I] the signs of RH, and then they don't know what they are looking at, because it isn't something they see often. Plus, of course, the very limited treatment options, with diet being the biggest and best solution. [/QUOTE]
