 [ Symptoms ] i get stomach pains and nauseous sometimes i can not eat for a whole day sometimes if i eat i will throw it back up sometimes it occurs when i am upset but it mostly just happens at random [ Disease ] hi this is genetic disorder that occurs due to an overactive sympathetic nervous system combined with fearanxiety if its in early stages you can just be cured by a counseller else you should consult psychiatrist and start appropriate anti sympathetic medicines thanks
