Sudden Nausea or Vomiting Without an Obvious Cause
Nausea and vomiting are easy to dismiss because they are linked to many common issues like a virus, spoiled food, motion sickness, anxiety, hormones, or an upset stomach. However, sudden nausea or vomiting can also occur in some stroke cases. Alone, these symptoms are nonspecific. What matters is when they appear abruptly, especially alongside neurological changes.
