Hi again,
The advice you are trying to get is to do with getting the correct tests done for a true diagnosis.
I can advise you to diet, be aware of certain foods, avoid sugary drinks and so on. But you will know that from our forum. A food diary to help you and your doctor to understand what is happening with your blood glucose levels.
Whatever it is, with the hypos, being non diabetic, not on meds that effect blood glucose levels, your GP and nurse will probably not have the training into Hypoglycaemia. So a referral to an experienced endocrinologist, who has the authorisation to get you the tests.
I was misdiagnosed with T2, it took me over a decade to get the tests. If it is not hypoglycaemia, you still need tests to find out why you are going hypo. You may have to be insistent and bully your doctor to get the referral you need. There are a number of conditions that it could be. And it needs investigating.
Keep asking if in doubt of anything.
Best wishes.
