Patterns of Straining
Straining describes excessive physical effort required to initiate or complete defaecation — bearing down forcefully, spending prolonged periods on the toilet, or experiencing difficulty passing stools despite urgency. It is a primary feature of constipation and occurs when stool is hard, large, or located in a rectal position that requires significant propulsive force to evacuate. Chronic straining elevates intra-abdominal pressure with each episode, contributing to haemorrhoids (dilated venous plexuses in the anal canal), anal fissures (small tears in the anal lining), pelvic floor prolapse, and, potentially, diverticular disease through chronically elevated colonic pressures. Rectal dyssynergia (pelvic floor dysfunction where the puborectalis muscle paradoxically contracts during defaecation rather than relaxing) produces straining despite normal stool consistency.

The Evidence
Evidence context: straining
What the research says about straining during bowel movements, and when to seek professional assessment.
Overall pictureStrong evidence base
Several well-supported approaches can reduce straining
Dietary fibre, toilet positioning, and pelvic floor biofeedback each have strong research support for reducing straining. Identifying the underlying cause matters, as some cases reflect a mechanical issue requiring professional assessment rather than lifestyle adjustment alone.
When to seek care promptlyCertain symptoms alongside straining require professional assessment without delay.
Seek prompt professional assessment if straining is accompanied by blood in the stool, severe abdominal pain with rigidity, persistent vomiting, or unintentional weight loss. These features may indicate a condition requiring investigation beyond self-managed approaches. Do not delay assessment if any of these are present.
What the evidence supportsThree approaches have strong research backing for reducing straining.
Increasing dietary fibre intake softens stool and reduces the effort needed for evacuation — this is among the most consistently supported interventions. Elevating the feet on a footstool during toileting changes anorectal angle and has strong evidence for easing passage. Pelvic floor biofeedback has strong evidence specifically for dyssynergia, where the pelvic floor contracts incorrectly during defaecation.
Understanding why straining happensStraining has several distinct causes, and the mechanism matters for choosing the right approach.
Straining most commonly results from hard or large stools requiring excessive propulsive force. However, rectal dyssynergia — where the puborectalis muscle contracts rather than relaxes during defaecation — produces straining even with normal stool consistency. Chronic straining raises intra-abdominal pressure repeatedly, which over time is associated with haemorrhoids, anal fissures, and pelvic floor changes.
Approaches worth exploringA range of evidence-informed options exist depending on the underlying cause.
Fibre and fluid intake adjustments are a practical first step for most people. Toilet positioning aids are low-cost and well-supported. Where dyssynergia is suspected, a pelvic floor physiotherapist can assess and deliver biofeedback therapy. Complementary approaches such as abdominal massage or mindfulness-based relaxation may support some individuals, though evidence for these is more limited.
When professional input adds valueSome presentations of straining benefit from specialist assessment rather than self-management alone.
If straining persists despite dietary and lifestyle changes, a healthcare professional can assess for underlying structural or functional causes. A pelvic floor physiotherapist is appropriate where dyssynergia is suspected. A gastroenterologist or colorectal specialist may be relevant for persistent or complex cases. Self-managed approaches are not a substitute for professional assessment when symptoms are ongoing or unexplained.
What the evidence does not coverNot every approach to straining has the same level of research support.
Evidence is strong for fibre, positioning, and biofeedback, but many complementary and holistic approaches have limited or preliminary research in this specific context. Individual responses vary, and what works depends on the underlying cause. This content is educational and does not replace professional assessment for persistent, worsening, or unexplained straining.
