Bowel obstruction does not usually cause elevated blood creatinine. There is no direct relationship between intestinal obstruction and elevated blood creatinine. Elevated blood creatinine is usually caused by strenuous exercise, high calorie diets, and high protein diets. Simple overeating or fasting does not cause elevated blood creatinine, so intestinal obstruction does not cause elevated blood creatinine. Intestinal obstruction is usually caused by foreign bodies in the intestine, intestinal torsion, roundworm obstruction and nerve inhibition, etc. Intestinal obstruction may cause abdominal pain, vomiting, abdominal distension and cessation of defecation, etc. It can be treated with surgical methods such as intestinal resection and intestinal anastomosis, intestinal stoma, or intestinal exstrophy, etc., under the guidance of the doctor. If intestinal obstruction or elevated blood creatinine occurs, you should go to the hospital in time to avoid delay and discomfort.
