2. Constipation due to drug factors: patients taking drugs for other diseases can also cause constipation, such as calcium antagonists such as verapamil, antispasmodics such as atropine and opioid painkillers such as morphine.
3. Intestinal obstruction: Intestinal obstruction refers to any cause of intestinal contents discharged poorly or can not be discharged, there are three types, one is intestinal adhesions, intussusception, intestinal tumors and other causes of mechanical intestinal obstruction; the second is intestinal paralysis, intestinal spasms and other causes of kinetic intestinal obstruction; the third is the mesenteric vascular embolism, such as caused by hemodynamic intestinal obstruction.
