Re: Sister (non diabetic) suffering from hypos can anyone he
There can actually be various reasons for going hypo as a non diabetic. My nurse helpfully gave me a copy of Practical Diabetes Vol 28 No 3 pages 97-144 and oddly enough I read about it just yesterday in the Diabetologists' question time section on page 106-7 and the answers on page 141-2.
The article gives about 13 reasons for hypolgycaemia in otherwise healthy people, one of which is called "post-prandial hypoglycaemia". This is what your sister is saying is happening so her Dr is incorrect to say it's "impossible"; however, GPs are not Diabetologists.
There is a choice of two very simple tests that can be done to see if post-prandial hypoglycaemia is at play, and her GP can arrange those I believe.
This is not advice from me and it is not a medical diagnosis, I'm just pointing out the inaccuracy of her GP's statement that going low after eating is "impossible", so that should she wish to revisit that GP or get a second opinion, she might have a little more information. I don't know how you'd go about finding that article if you want to read it but you could try your diabetes team.
