Nausea is a common health symptom that, in most cases, can be treated at home, according to the Mayo Clinic. But if your symptoms don't get better after 24 hours, you're experiencing dehydration or are also feeling abdominal pain, you should seek medical attention, University of Maryland School of Pharmacy professor Cherokee Layson-Wolf, PharmD, tells USA TODAY.

Here, medical experts are answering some commonly-Googled questions about nausea.

What helps with nausea?

Nausea is a symptom, rather than a condition, according to Johns Hopkins Medicine. And so to improve your nausea symptoms, it's helpful to first get to the bottom of what's causing it, Layson-Wolf says.

Common causes of nausea can include motion sickness, over-eating, pregnancy, medication side effects and illnesses including viral and bacterial infections or food poisoning, experts say. For many cases of nausea, experts say over-the-counter medications including Pepto Bismol, Emetrol and Tums can provide relief.

"Nausea can be a nonspecific symptom and the concern is related to how long it occurs and whether it leads to vomiting, loss of appetite and eventually weight loss," Layson-Wolf notes.
