A huge thank you for suggestions and help. This is the first time I have ever posted on any forum, and I am rather bowled over by the kind and thoughtful responses. This has been rather a long road for me, and I am now thoroughly guarded against premature 'over excitement' if i think I might have found the answer. And I have long ceased to rely on medical professionals in our poor, ragged NHS. Unless you have something text book easy to diagnose, it pretty well falls to us to direct our own dogged research, the community of caring, knowledgeable people as on this forum is just invaluable.
Responses have given me confidence that this is a possible cause of my condition and is well worth exploring. Lamont D's confirmation of shared symptoms is encouraging and a relief.
As the Freestyle Libre is expensive, it might be advisable to buy the cheapest meter I can, to check I have a problem first, then invest in it for detailed information if I do. I would welcome advise on cheap meters - is this a 'you get what you pay for' situation, where very cheap options are thoroughly unreliable? In which case, what is a safe 'entry point'? If that cost is close to the Freestyle Libre anyway, it might be better to just go for that. As CherryAA points out, really KNOWING what's going on is invaluable either way. Is the Freestyle Libre the only waty of REALLY knowing rather than just having some indication?
It seems testing with a glucose meter is all I need to do before seeing the doctor, then 'nicely' insisting on referrral to an informed specialist if my own test results are positive. From another part of the (hugely informative) forum I found this:
"If you believe you have a form of hypoglycaemia, and you need a bunch of tests to rule out other conditions, the only way forward is to get a referral from your GP. Your GP can find an endocrinologist, who has specialist knowledge in Hypoglycaemia.As it rare, then the tests you need are a hba1c to see if you have normal glucose levels. Unless your insulin resistance is high that distorts your test.Then a prolonged OGTT (oral glucose tolerance test) (5hours) which will show how quickly you spike, then if you hypo after more than two hours. During this test other blood tests should be done, including GAD and c-peptide. If that shows that there is a possibility of you having RH. Then the next test is probably a breakfast tolerance test (you are given bread, butter jam and a drink, then they monitor your blood glucose levels and take blood for tests for other conditions. The last tests are to eliminate insulinoma or pancreatitis or pancreatic cancer, which is a 72 hour prolonged fasting test in hospital."
That’s quite a lot of testing! Not sure NHS would do the last one as routine unless other strong indications cancer (or the rest) a possibility. I assume that the detailed results from the Freestyle Libre really would be reliable enough for my own diagnosis purposes? (Before confirmation by other tests). Enough to dive into the no carbohydrate diet and, with a fair wind, and at last knowing what I am dealing with, getting control.
