Nausea is a common symptom characterized by a feeling of queasiness or stomach discomfort, often accompanied by an urge to vomit. It can be acute or chronic and may be triggered by various factors.

Causes of Nausea

• Gastrointestinal issues: Gastroesophageal reflux disease (GERD), gastritis, ulcers, inflammatory bowel disease (IBD), and irritable bowel syndrome (IBS) can cause nausea.
• Infections: Viral gastroenteritis, food poisoning, and other infections such as meningitis or encephalitis can lead to nausea.
• Pregnancy: Morning sickness is a common symptom experienced by many women during pregnancy, typically during the first trimester.
• Motion sickness: Traveling by car, boat, plane, or other vehicles can cause nausea in some individuals.
• Medications: Certain medications, such as antibiotics, pain relievers, and chemotherapy, can induce nausea as a side effect.
• Medical conditions: Migraines, vertigo, labyrinthitis, and other inner ear disorders can cause nausea.
• Psychological factors: Anxiety, stress, and depression can contribute to nausea in some cases.
