Please explain what does it mean when you vomit clear liquid consstantly even with no water intake?

Repeated vomiting: If you have repeated vomiting, you need to go to a ER to assess how dehydrated you are and why you're vomiting. The fact that your vomitus is clear means that you have eaten no food for about an hour before the vomiting. You need to have some X-rays of your abdomen taken to make sure you do not have an intestinal obstruction causing you to vomit repeatedly, among other causes. Good luck
