Hi and welcome to our forum.
what I can glean from your posts is you feel as I did when I was going through the hypos prior to diagnosis and finding myself looking for answers and how to stop the hypos, but there was at the time only one place to find the only advice that worked for me. It was the only place advocating going keto.
If it is RH, the problem you have is intolerance to many foods which will trigger the excess insulin you produce that causes the hypos.
Where your doctors are not understanding the science, they are trying to treat the symptoms after the trigger has already happened. It will of stop the hypos of stop the symptoms.
What I realised with help was to stop the trigger. If it is food, that is causing the hylos, then don't eat that food!
I was being told for over a decade that the eat well plate would make me healthy. When in fact, porridge for breakfast, baked spud, baked beans for lunch. Roast dinner for tea and so on. However after tests, experimenting and keeping a good diary, testing every meal, I found that I didn't hypo after going keto. Of course because of how bad I was, it took time to sort it and I did more research, more testing, more aiming to my specialist endocrinologist, who was brilliant in agreeing with the treatment I was using.
I have read posts on here about Acerbose being prescribed for RH, it is not designed to help of treat RH, the theory is to help you absorb the carbs easier, but it doesn't! This is how I know you doctor doesn't understand the science behind RH.
I took part in clinic trials which meant I had several extended oral glucose tolerance tests, we found that the drug I was taking helped with my very weak initial insulin response. Which is a part of RH. This helped lower the spike that triggered the excess insulin. But it didn't prevent the hylo. But as a back up plan if I didn't stay in ketosis, it would limit the symptoms and the hypo didn't cause me problems.
It was sitagliptin that I'm taking, there is a video on YouTube about it and the clinical trials are on the internet.
I hope you have read about RH it won't be easy, it is now over ten years since diagnosis. But for a couple of instances, I have been hypo free and symptoms free. You don't have to live with it, control it, control your blood glucose levels, your body and brain eventually will be in favour of it.
Have a read and decided yourself how to go about controlling this condition.
