I was prescribed HRT by a 'diabetic' consultant, when I first hit menopause symptoms, or rather when they hit me. He told me that only a small percentage of female type 1 diabetics are affected by crazily changing BS levels in this way. My GP had been zero help in the previous three months. which had seen my BS regularly spike for no reason. On the first occasion it happened, it climbed from a point in the 4s to 22 mml in an hour or so. When I asked what percentage of us were affected in this way, he didn't want to give a figure, but when I suggested 5%, he said it was lower than that.
I have posted several times about this. Nobody accused me of doing anything wrong diet-wise, probably because I had previously been extremely well-controlled for 20 plus years and I had been dealing with type 1 from the age of 10, so they accepted the situation I was describing to them was real. My GP was startled when he got the hospital letter recommending he prescribe HRT, as I gather he would not normally have prescribed this for a type 1, but he went along with it and it rescued me from a desperate situation. It wasn't a perfect solution. I still got spikes to 12 mml or so, but I could cope with that. HRT doesn't work for everyone - but it did for me. You would be likely to need a consultant to prescribe it. It is not something GPs seem to know anything about. If you run a search for HRT on this forum, you should find earlier messages I have posted about this.
