"Nausea: Causes, Remedies, and Warning Signs"

Nausea is a symptom rather than a condition and can be caused by various factors such as motion sickness, over-eating, pregnancy, medication side effects, and illnesses. Over-the-counter medications like Pepto Bismol, Emetrol, and Tums can provide relief, and consuming bland foods, clear fluids, and ginger ale may help alleviate symptoms. However, if symptoms persist for more than 24 hours, dehydration occurs, or abdominal pain is present, seeking medical attention is advised.
