Why do you vomit in hernia?

Vomiting in the presence of a hernia can occur due to obstruction or strangulation of the intestines. When a portion of the intestine becomes trapped in the hernia, it can lead to a blockage, preventing food and fluids from passing through. This obstruction can cause nausea and vomiting as the body attempts to expel the contents. Additionally, increased abdominal pressure from the hernia itself can contribute to these symptoms.
