Constipation

General Information

Constipation is a common condition in the digestive tract characterized by difficulty passing stools.  Commonly, patients report symptoms such as infrequent bowel motions, difficulty or straining when passing the stool or a sensation of incomplete evacuation. Constipation may be associated with abdominal pain which is relieved after passing a bowel motion, bloating, tiredness, reflux, nausea and increased flatulence.

Necessary Investigations

To investigate your condition, your Gastroenterologist may order further investigations such as blood tests, stool tests, abdominal x-ray, abdominal ultrasound, colonic transit studies, Panendoscopy and / or Colonoscopy but any necessary tests will be discussed with you when you see your doctor at consultation.

To aid with diagnosis and treatment planning, please bring results of investigations performed to date with you to your appointment.

Causes

Constipation may be caused by medications, low activity of the thyroid, elevated levels of calcium in the blood and rare genetic disorders (to name a few), but after these have been excluded the most common cause of constipation remains unclear.

 

Research conducted at the Centre for Digestive Diseases4 and elsewhere1,2,3 indicates that an altered gut microbiota may be a cause in this subset of patients.

Treatments

As the chronic constipation may stem from bacteria, after excluding other causes for your condition, your gastroenterologist may consider targeting your treatment at the gut microbiome 1,5.
