Am I constipated? (Explained in a way only your pharmacist can…)
Am I Constipated? Do I have Irritable bowel with constipation? Am I impacted?
Pathophysiology of constipation. “Pathophysiology” is just a fancy medical term that means the study of abnormal changes in body functions that are the causes or consequences of the disease.
Constipation is usually defined as hitting the washroom (defecating) fewer than 3 times a week with other symptoms that can include hard stools; feeling of incomplete evacuation (“Still feeling something”); too much forcing/straining ; a feeling of a block in the rectum; and abdominal uneasiness/pain and bloating.
You might incorrectly believe that a daily trip to the bathroom is important and that anything less means “Oh no, I’m constipated”. Actually, the typical number of bowel movements for an adult and for kids 3 years and older varies from 3 daily to once every 3 days. The would be typical for someone on a Western diet. What you eat and drink matters- obviously!
Constipation occurring chronically (regularly) is termed functional or chronic idiopathic constipation. This assumes that your cause of constipation is not the result of a drug side effect or that there is something physically wrong with your bowel.
If your constipation is a side effect of a chronic drug you are taking or a disease- and you do not seek to treat it this may cause serious complications! You can see complications like obstruction, anal fissures (cracks), hemorrhoids, abnormal dilation (swelling) and twisting of the colon and pelvic organ prolapse (a drop) in women.
If you are curious to deepen your official knowledge of constipation criteria here are the Rome IV criteria for chronic and opioid (narcotic drugs) constipation
What can make you at risk for chronic or acute constipation (Also known as your “risk factors”)
- Ignoring the urge
- Living in rural, northern or mountainous areas in North America
- Over 65 years of age
- Fewer years of formal education and lower socioeconomic status
- Low caloric intake
- A large number of daily meds
- Physical and sexual abuse
- Sedentary lifestyle and travelling
What about IBS (Irritable Bowel Syndrome) – can it cause constipation?
There is growing information revealing an overlap between functional constipation and irritable bowel syndrome with a predominant constipation side (IBS-C). It is difficult to categorically diagnose IBS-C even if investigated with physiological testing, an abnormal balloon evacuation test, imaging etc…. If you have bloating and or pain with an average of 1 painful constipation episode per week over the past 3 months, you may well be suffering from Irritable bower syndrome with constipation (IBS-C). Constipation with bloating and/or pain, are not main features of functional constipation so chances are it’s IBS-C
What about Fecal impaction? Could it be it?
Well Fecal impaction is the inability to pass a hard collection of stool. Symptoms that you may be experiencing is rectal discomfort, nausea, vomiting, abdominal pain, increase need to urinate- you can even see urinary and fecal incontinence.
Watch out for it in physically or mentally incapacitated persons and the elderly. This group of people are at particular risk of fecal impaction, as are those who require long-term use of medications associated with constipation as a side effect.

Take a proper look at your diet, level of exercise and relevant social or psychological problems. What has changed in your life that can be improved that may contribute to the constipation ?
At first, review prescription and non-prescription medications to rule out drug-induced
causes. Are you taking any of the drugs on the list above?
Also look at the natural health products since their overuse could cause gut dysfunction and constipation.
Signs and symptoms of constipation include:
■ Infrequent defecation
■ Abdominal distention
■ Early satiety
■ Stools that are small, hard and/or difficult to evacuate
Which ones are the most troublesome?
What past laxative have you used and failed- this will to help maximize adherence and reduce possible side effects. Keep in mind that if you are suffering from opioid induced constipation, up to 28% of patients do not take the prescribed laxatives by their doctor while 25% of those patients use laxatives only intermittently!
Did you know there is an official chart about the different forms of observed formed of feces called The Bristol Stool Form Scale (BSFS)? It is tool to help describe bowel patterns in a way that is more useful for diagnosis and evaluation of treatment- I wish I could tell you how this visual chart was conceived and how agreement was reached but it’s a real thing!
