I was wondering if anyone knows what this could be - I have started having hot flushes and feeling very lightheaded and shaky from time to time. I am 47 so thought it could just be perimenopause but have realised today that this happens mostly when I have eaten a lot of sweets. I am now wondering if it’s blood sugar related. I have been on steroids in the past and had hot flushes from those and this feels very different. I am not red and you couldn’t tell anything was happening from looking at me. Any ides what it could be / if I should see a doctor? Obviously I will stop eating sweets now I have made the connection.
