Nausea one week after cholecystectomy may be normal such as the effect of anesthesia and carbon dioxide stimulation during surgery, or it may be abnormal such as enteritis and other diseases. 1.Normal phenomenon (1) The effect of anesthetics during surgery: the digestive tract has not fully recovered from the surgery and will be sensitive to the reaction of anesthetics. Patients will have some nausea, but this will disappear in a short time. (2) Stimulation of carbon dioxide: Currently, the most commonly used procedure is laparoscopic cholecystectomy, while laparoscopic cholecystectomy requires artificial pneumoperitoneum because the gas contains carbon dioxide, which will cause some stimulus|stimulation to the patient, resulting in nausea symptoms. With the patient’s carbon dioxide metabolism and the disappearance of pneumoperitoneum, the feeling of nausea will slowly disappear. 2. Disease causes: Nausea may be caused by gastroenteritis, which is due to the stimulation of inflammation, resulting in abnormal gastrointestinal peristalsis, and nausea, vomiting and diarrhea due to insufficient absorption of water and sodium. If the symptoms of nausea appear one week after gallbladder removal and continue unrelieved, you need to seek medical treatment.
