Chronic Idiopathic Constipation (CIC)

CIC involves difficult, infrequent, or incomplete bowel movements lasting ≥3 months without secondary causes. Subtypes include normal-transit (functional) constipation, slow-transit constipation (colonic inertia), and defecatory disorders (pelvic floor dyssynergia). Tailored evaluation guides therapy.

Symptoms (Rome IV)

• Two or more of the following in ≥25% of defecations:
• Straining
• Lumpy/hard stools (Bristol 1–2)
• Sensation of incomplete evacuation or obstruction
• Manual maneuvers to facilitate stool
• <3 spontaneous bowel movements per week
• Loose stools rarely present without laxatives
• Insufficient criteria for IBS

Evaluation

• History (diet, meds, comorbidities), physical exam, digital rectal exam
• Alarm features (bleeding, weight loss, anemia, new onset >50) prompt colonoscopy
• Labs (TSH, calcium) if clinically indicated
• Stool diary/Bristol chart for baseline
• Further testing for refractory cases:
• Anorectal manometry + balloon expulsion test (defecatory disorder)
• Colon transit study (radiopaque markers, scintigraphy)
• Defecography or MRI for structural issues

Treatment Strategy

Lifestyle & First-Line

• Gradual fiber increase (20–30 g/day) + adequate hydration
• Regular physical activity
• Scheduled toilet time after meals (gastrocolic reflex)
• Osmotic laxatives (polyethylene glycol), stool softeners

Pharmacologic Escalation

• Stimulant laxatives (senna, bisacodyl) short-term or intermittent
• Secretagogues: lubiprostone, linaclotide, plecanatide
• Serotonin 5-HT4 agonist: prucalopride
• Tenapanor for IBS-C but sometimes used off-label
• Use combination regimens tailored to stool form/frequency

Pelvic Floor Dyssynergia

• Biofeedback therapy (first-line) + pelvic floor physical therapy
• Avoid surgery without addressing pelvic floor dysfunction

Refractory Slow-Transit Constipation

• Consider prokinetics, neuromodulation (sacral nerve stimulation)
• Subtotal colectomy with ileorectal anastomosis in carefully selected patients

Supportive Measures

• Manage medications that worsen constipation (opioids, anticholinergics)
• Address psychological factors (stress, anxiety) via CBT
• Ensure adequate sleep—circadian disruption affects motility

Living with CIC

• Track stool frequency, form, laxatives, fiber/water intake, symptoms
• Identify dietary triggers (low-FODMAP trials for bloating)
• Use abdominal massage, breathing exercises to stimulate motility
• Maintain positive relationship with food—avoid excessive restriction

Complications

• Hemorrhoids, anal fissures, rectal prolapse
• Fecal impaction
• Decreased quality of life, anxiety/depression

Research & Future Directions

Exploring microbiome modulation, neuromodulation, and personalized motility mapping.

Experimental & Emerging Treatments

• Intestinal Neuromodulation: Transcutaneous vagal stimulation and sacral nerve stimulation for motility.
• Microbiome-Based Therapies: Targeted probiotics, synbiotics, and fecal transplant aimed at improving transit time.
• Smart Toilets & Digital Tracking: Objective stool monitoring to tailor therapy.
• Enteric Neuron Regeneration: Stem-cell approaches for severe colonic inertia.
