What Is Constipation?

Constipation occurs when there is an abnormal decrease in bowel movements (fewer than 3 times a week) and difficulty passing stools. Stools passed are also usually hard and dry.

Acute constipation is usually not a sign of a serious medical condition. However, persistent and chronic constipation may signal a more severe medical issue and result in more serious complications.

If you are experiencing abnormal and persistent constipation, you should see a specialist.

What Causes Constipation?

Constipation can occur when there is inadequate fluid intake or lack of fibre in the diet. This results in hard and dry stools, making it difficult to pass them out. Sometimes the colon itself contracts more slowly resulting in the slower passage of stools through the colon.

Causes of constipation include :

  • Low fibre diet
  • Dehydration (inadequate water intake)
  • Blockages in the colon or rectum (Intestinal obstruction)
  • Physical inactivity
  • Side effects of specific medications
  • Irritable bowel syndrome (IBS)
  • Nervous system disorders such as Parkinson’s
  • Colorectal cancer

How Is Constipation Evaluated?

  • Review of medical history and lifestyle habits
  • Physical examination (rectal exam)
  • Imaging tests such as x-rays and CT scans may be used to detect any intestinal blockage
  • Colonoscopy or sigmoidoscopy to examine the inside of the colon and rectum
  • Specialised tests such as anorectal manometry and video defecogram
  • Blood and stool sample tests

Treatment Options For Constipation

Over-the-counter medications and laxatives

  • Fibre supplements
  • Stool softeners such as lactulose
  • Osmotic agents such as milk of magnesia
  • Lubricants such as mineral oils
  • Stimulants such as senna, bisacodyl

LIfestyle changes

  • Drink plenty of water
  • Consume more fibre-rich foods such as fruits, vegetables and whole grains

Surgical options are rare and only considered if non-surgical treatment methods are ineffective and the constipation is caused by an intestinal blockage or structural problems of the intestines.
