Hi Shelster

The most important way to stabilise blood sugar as CLKD says is to eat slow release foods. Maybe run us through your typical day and what you eat? Many women seem to find problems with blood sugar regulation on becoming peri-menopausal. I certainly did and still do have problems and I take HRT (have done for 13 years). You do not need to eat through the night. Blood sugar is highest in the early hours, but maybe eat something light before you go to bed. I often have a small bowl of natural yogurt last thing as I get very hungry late eve and first thing in the morning for some reason!
Cut out added sugar as much as you can as well as refined carbs white flour pastries bread etc and go for whole grains alternatives but also cut down on the amount of carbs you eat (if you eat a lot of these) and replace with low fat protein which fills you up for longer. Also cut down on juice and sugary drinks if you eat lots of these, for example too.
HRT hasn't made a difference in that sense to me although I think the hormonal fluctuations make blood sugar fluctuations more noticeable in some women.
I presume you have had blood sugar tests as well to see what is actually hapening? If you're like me then it's called non-diabetic hypoglycaemia or reactive hypoglycaemia and doesn't need to be diagnosed by a doc except in the first instance to rule out diabetes. To al intents and purposes the symptoms are excatly like proper hypo ie intesne hunger, sweating and trembling, weakness so you have to eat glucose/sugar quickly to feel OK again which takes a few minutes. This is not good in the long term (eating sugar) so that's why you need to later your diet, how much and what you eat and recognise the signs. I have a pretty big breakfast as my weak point is mornings and if I do an exercise class ( not done since lockdown!) without a big breakfast it will happen while I'm in the class!
