Rectal Prolapse Causes

• Rectal prolapse is caused by weakening of the ligaments and muscles that hold the rectum in place. In most people with a prolapsed rectum, the anal sphincter muscle is weak. The exact cause of this weakening is unknown; however, rectal prolapse is usually associated with the following conditions:
  
  
  • Advanced age
    
    
  • Long-term constipation
    
    
  • Long-term diarrhea
    
    
  • Long-term straining during defecation
    
    
  • Pregnancy and the stresses of childbirth
    
    
  • Previous surgery
    
    
  • Cystic fibrosis
    
    
  • Chronic obstructive pulmonary disease 
    
    
  • Whooping cough
    
    
  • Multiple sclerosis
    
    
  • Paralysis (Paraplegia)
• 
  
• Long-term hemorrhoidal disease is frequently associated with mucosal prolapse that does not progress to complete rectal prolapse.
