The 60-year-old master Wang felt uncomfortable in his stomach after “eating a lot of red meat” that night, and eventually couldn’t bear the increasingly severe abdominal pain after 2 hours at home, and was sent to the hospital by his family, which was examined for acute intestinal obstruction and required immediate surgery. But the old man was reluctant, afraid that the operation would hurt his vitality, and then after repeated communication between the doctor and the family, the operation was performed immediately. However, because the elderly did not seek medical consultation and surgery in time after the occurrence of intestinal obstruction, it led to intestinal necrosis and serious infection, and there was no rise in blood pressure, generalized cold sweat, nausea and vomiting, and shock occurred. After active resuscitation by medical staff, Master Wang finally turned to safety. It turned out that Master Wang had just had gastric cancer surgery a year ago, after which he felt that the surgery would make his physique decline and that he needed a big nutritional supplement after surgery. Since the first half of this year, he defied his family, every day in addition to exercise programs such as push-ups, but also to eat large fish and meat for large supplements, especially love to eat roast pork, pork knuckles, fried rice with eggs. In fact, this kind of diet is not good for the health of the elderly. After radical surgery for gastric cancer, the digestive function of the elderly is weakened, especially at night when they eat a lot of greasy meals, which are not easy to digest, and too much food accumulates in the intestinal tract, resulting in intestinal obstruction, coupled with the lack of timely medical surgery and timely release of obstruction, resulting in ischemic necrosis and infection of the obstructed intestinal segment.
