Why do oranges cause you to vomit?

Oranges can cause vomiting in some individuals due to their high acidity, which may irritate the stomach lining, especially in those with sensitive stomachs or conditions like acid reflux. Additionally, some people may have an allergic reaction or intolerance to certain compounds in oranges, leading to gastrointestinal distress. Eating too many oranges in a short period can also overwhelm the digestive system, resulting in nausea and vomiting.
