Sudden fever after gastric cancer surgery is mainly considered to be related to postoperative hematoma and fluid absorption and heat production, postoperative infection and metabolic disorder, etc., and needs to be analyzed according to the severity and duration of fever.
1. Postoperative fever due to hematoma and seepage absorption: after gastric cancer surgery, if sudden fever occurs in the early postoperative period with axillary temperature not more than 38.5 degrees, it is mainly considered to be related to the absorption of hematoma and abdominal seepage, which is a normal physiological phenomenon.
2. Post-operative infection: if the fever after gastric cancer surgery suddenly rises, the axillary temperature exceeds 38.5 degrees and lasts for a long time, accompanied by other symptoms, it cannot be excluded that it is related to post-operative infection, such as infection of the wound in the abdominal cavity or infection of the abdominal cavity.
3. Metabolic disorder: gastric cancer belongs to a kind of malignant tumor, which consumes more energy to the body, so after gastric cancer surgery, there is a possibility of metabolic disorder, which will lead to lower resistance, anemia, emaciation, etc., and thus lead to the symptom of sudden fever after surgery.
Sudden fever after gastric cancer surgery needs to be reviewed by doctor as early as possible to prevent complications, and be treated positively after the cause is clarified.
