Slow Transit Constipation

Understanding Slow Transit Constipation

Slow transit constipation is characterised by slower than normal movement of waste through the digestive system. This type of constipation typically results in fewer than three bowel motions per week and is often associated with abdominal bloating/pain and nausea. This is due to the faeces being backlogged in the colon.

  • Infrequent bowel motions
  • Abdominal bloating and discomfort
  • Nausea
  • Reduced urge sensation to defecate
  • Unsatisfactory bowel emptying

For many people, the cause of slow transit constipation is unknown. However, it can be associated with

  • Genetics
  • Eating disorders
  • Prolonged laxative use
  • Hypothyroidism
  • Neurological disorders
  • Side effect of medications

The first step in diagnosis of slow transit constipation is a though history and physical examination. Further evaluation to confirm diagnosis includes

  • Colonic transit studies
  • Colonoscopy
  • Functional assessment of the muscles in the anorectum via digital rectal examination and/or anorectal manometry.

Treatment of slow transit constipation often includes input from a multidisciplinary team. Common treatment options may include;

  • Stool manipulation through changes to dietary fibre, fluid intake and modification to laxative regimes
  • Optimising defecation technique including your toileting position, use of abdominal and pelvic floor muscles and passive support/splinting (if prolapse is relevant for you).
  • Adjunctive therapies such as interferential therapy to stimulate the peristalsis motion and improve the speed of waste through the colon.
  • Lifestyle modifications including physical activity, weight loss, sleep hygiene and overall relaxation to stimulate on the parasympathetic nervous system (also known as the rest and digest state)
