Nausea

Nausea is a subjective sensation of an urge to vomit, often accompanied by discomfort in the stomach. It is clinically significant as it can indicate underlying conditions such as gastrointestinal disorders, infections, or neurological issues, and may lead to complications like dehydration or electrolyte imbalances if vomiting occurs. A common association is with motion sickness, which highlights the role of the vestibular system in the nausea pathway.
