Hi all. I have been lurking for a while and I need some help today please. I have hypoglycaemia. Both reactive after food and overnight after 5-6 hours without food. I had a gastric bypass five years ago and this is thought to be the cause of it. I have a fantastic endocrinologist who is working hard with me to resolve this. I am taking adizem (a calcium channel blocker) and yesterday I started sitagliptin. I took the sitagliptin at tea time. Great night - first night without a hypo in three. Months! BUT - today has been a really tough day. I went hypo after breakfast and have basically stayed there all day. I have even tried fruit juice and oatcakes; glucose tablets (two) and milk as well as my normal high protein low fat solutions. So, what can I do to bring my levels up? I wear a CGM and have confirmed the readings with my accu-chek - I am bouncing from 2.1 up to the dizzy heights of 4.0 and then drop down to 3.4 and steadily decline all the way back to the high 2,s. Could the sitagliptin have caused this? I was so pleased to be hypo free overnight! Any ideas?
