Final answer:
Hyper- means excessive. The word that means excessive vomiting is hyperemesis.
Step-by-step explanation:
Hyperemesis is a term denoting excessive vomiting, a condition marked by severe and prolonged bouts of throwing up. This medical issue is frequently observed in pregnancy, posing risks like dehydration and weight loss if not effectively addressed. The word itself breaks down into 'hyper-' as a prefix, meaning excessive, and 'emesis,' which specifically refers to the act of vomiting. In cases of hyperemesis, the body expels stomach contents extensively, often requiring medical attention to manage symptoms and prevent complications. Understanding this term aids in recognizing and addressing the challenges associated with severe vomiting, particularly in the context of pregnancy-related conditions.
