Nausea is a distressing sensation characterized by a feeling of discomfort or unease in the stomach, often accompanied by an inclination to vomit. It is not a specific condition but rather a symptom that can be caused by various underlying factors. Nausea is commonly experienced when the body’s digestive system, particularly the stomach, is irritated or when there is a disturbance in the balance of the inner ear (vestibular system).
