Nausea is the feeling of sickness in the stomach, often leading to vomiting, which is the forceful expulsion of stomach contents. Common causes include viral infections, food poisoning, motion sickness, or sometimes stress. When consulting a doctor, they will likely ask about recent food intake, travel, associated symptoms like fever or diarrhea, and how long it has been happening. It's useful to track what you've eaten, how frequently you're vomiting, and if you can keep fluids down. Seek urgent care if vomiting is severe or persistent, if you cannot keep any fluids down for several hours, if there's blood in your vomit, or if you show signs of severe dehydration like dizziness or reduced urination. We'd love to hear your insights.
