Gastric perforation itself and the symptoms caused by gastric perforation do not normally affect the patient’s life expectancy, but in the case of severe uncontrolled abdominal infection or even infectious toxic shock, it may kill the patient within a short period of time. Whether or not this affects life expectancy and for how long depends on factors such as the severity of the disease and physical condition. Gastric perforation is a kind of acute abdominal disease, which can usually be caused by overeating, ulcers, tumors, drug effects, etc. It may present with symptoms such as sudden severe pain, nausea, vomiting, fever, accelerated heart rate, shock, etc., and requires prompt medical attention. If the gastric perforation is small, conservative treatments such as gastrointestinal decompression, anti-infection, intravenous rehydration, etc., can usually be cured and will not affect life expectancy. If the perforation is large and combined with obvious signs of peritonitis, surgical treatment is needed to control the infection after surgery, the general prognosis is good and does not affect the life, but if not treated in time may be life-threatening; if complicated by serious peritoneal infection, may cause infectious shock, if not treated in time or the treatment has no good effect, it can seriously affect the patient’s life expectancy. Therefore, gastric perforation requires prompt medical attention and, if necessary, surgical treatment. With timely and effective treatment, the patient’s life can be saved and the prognosis can be improved.
