aloha and thank you. for the last several months, i have been experiencing recurring nausea, accompanied by occasional vomitting, coupled with a heavy feeling of water fullness in my stomach. i do not think I'm overweight and probably not pregnant. what might be the cause of this? i do not smoke cigarettes and have no known health conditions. i do not recall ever having this type of feeling before (with the exception of when I just plain get sick, but then it's just for the time being, not recurring) i am 37, female, mixed heritage, residing in Hawaii. I hope somone can point me in the right direction. Mahalo!
