Hello. I m an 18 year old female, I have started getting shakey and very weak after not eating for just over an hour, I frequently have to eat small snacks to stop this ( but not gaining any weight in this process ) my meals are normal as they should be, healthy. I used to binge eat for comfort from age 13-16 but not it is monitored, I am a smoker ( 15 a day average ). Iv asked around and people think it may be my sugar levels but I m seeking professional help as tonight as I write this I found myself shakey and weak unable to move out of bed just an hour after eating my dinner ( a full meal ) I don t understand what causes this, but I also suffer frequent flashing migrains every few weeks or so. I really hope I can get to the bottom of this, it s not nice feeling so weak all the time, regards.
