Nausea can have many possible causes, including digestive problems (such as food poisoning, indigestion, gastritis, or acid reflux), infections like stomach flu or viruses, motion sickness, pregnancy (morning sickness), anxiety or stress, medication side effects, migraines, dehydration, low blood sugar, and inner ear issues affecting balance. It can also be a symptom of other medical conditions or responses to certain foods or environmental triggers.
If nausea is persistent, severe, or accompanied by other serious symptoms like chest pain, confusion, high fever, or severe pain, medical attention should be sought.
The specific reason for feeling nauseous depends on individual health context and accompanying symptoms.
