Constipation

About

  • Having fewer than three bowel movements a week

  • A bowel movement is painful and stools are difficult to pass
  • A feeling that you have not fully emptied your bowels

Causes

  • Older age
  • Stress
  • Being a woman, especially while you are pregnant and after childbirth
    • Hormonal changes 
    • The baby inside the womb squishes the intestines, slowing down the passage of stool
  • Changes in your regular routine ie: traveling
  • Not eating enough foods rich in fibre
  • Not drinking enough water
  • Taking certain medications 
  • Having certain neurological and digestive disorders

  • Stools are dry, hard and/or lumpy
  • Stools are difficult/painful to pass
  • Stomachache/cramps.

Diagnosis

  • Medical history and bowel movement history
  • Physical exam, including rectal exam
  • Lab tests: Blood and urine tests to check for hypothyroidism/anemia/diabetes
  • Stool sample: To check for signs of infection/inflammation/cancer
  • Imaging tests: Computed tomography (CT), magnetic resonance imaging (MRI) or lower gastrointestinal tract series may be ordered to identify other problems 
  • Colonoscopy:  An internal view of your colon with a scope – may be performed
  • Colorectal transit studies: These tests involve consuming a small dose of a radioactive substance, either in pill form or in a meal, and then tracking both the amount of time and how the substance moves through your intestines
  • Defecography:
    • A small amount of liquid barium is released through a tube into the colon and rectum
    • An x-ray video is taken that shows how the rectum is functioning
  • Anal manometry:
    • A short, thin tube is inserted up into the anus and rectum to measure sphincter tightness
    • Studies the strength of the anal sphincter muscles

Treatment
