recently whenever i train more than 15 minutes, even if it’s only fast walking on treadmill, sometimes lifting weights. i’ll feel some low blood sugar symptoms: a little bit dizzy, hand shaking…etc. all these symptoms will gone if i drink a high sugar post-workout drink (e.g. cell-tech), and eating a big meal within 1 hour. anyone knows what kind of problem is that? is that i’m getting diabetes? thanks for help.
(i’ve been training on/off for almost 20 years,i’m 36 years old already, recent years i’m getting fatter and not able to lose any bodyfat)
