What are the symptoms of gastric perforation?

The main symptoms of gastric perforation include: 1. Abdominal pain: Sudden onset of severe abdominal pain, initially starting in the upper abdomen or at the site of the perforation, often described as knife-like or burning in nature. The pain is generally persistent, though it may episodically worsen, and it rapidly spreads to the entire abdomen. 2. Symptoms of shock: During the early stage of perforation, patients may experience a certain degree of shock symptoms. As the condition progresses, bacterial peritonitis and intestinal paralysis may develop, potentially leading to toxic shock. 3. Nausea and vomiting: Some patients may experience nausea and vomiting, although usually not severe. If intestinal paralysis occurs, vomiting intensifies and may be accompanied by abdominal distention and constipation. If the above symptoms occur, please seek immediate medical examination and treatment at a hospital.
