I need help. i have constant emptying of stomach and shakiness. nothing feels settled in my stomach. no vomiting but i feel very malnourished?

Needs evaluation: Your symptoms could be all kinds of things, from irritable bowel syndrome to reflux to diabetes and more. Best thing to do is to go to your regular doctor and discuss all this with them. They can do a thorough check and at least rule out the bad stuff. Could be that even some simple treatments might could get you some relief...but it needs to be looked at more closely. Good luck.
