Why Do I Feel Like I Haven't Fully Emptied My Bowels?
The feeling of not fully emptying your bowels is called incomplete evacuation or incomplete defaecation. It is a recognised clinical symptom with several identifiable causes including IBS, pelvic floor dysfunction (specifically dyssynergic defaecation), rectocele, internal haemorrhoids, constipation, and rectal prolapse. It is not something that should be normalised or ignored.
Treatment depends on the underlying cause and may include biofeedback therapy, dietary modification, medications, or bowel retraining. A clinical assessment including anorectal physiology testing can identify the specific cause and guide effective treatment.
It is one of the most frustrating bowel symptoms — the persistent sensation that you have not fully emptied after going to the toilet. You go, but it does not feel complete. You may return to the toilet multiple times without relief. The feeling lingers throughout the day.
This symptom has a clinical name: incomplete evacuation. It is extremely common, yet many people who experience it have never had it properly investigated or explained.
What Is Incomplete Evacuation?
Incomplete evacuation — sometimes described as the sensation of still needing to go after just going — is one of the most common bowel complaints seen in clinical practice. People often return to the toilet multiple times without relief, spend longer than necessary trying to empty, strain significantly, or carry a sense of rectal pressure or fullness throughout the day.
What Causes the Feeling of Incomplete Bowel Emptying?
Several conditions can produce this symptom, and identifying the correct cause is essential for effective treatment.
IBS (Irritable Bowel Syndrome) is one of the most common causes. Altered gut motility and visceral hypersensitivity can produce a persistent sensation of incomplete emptying even when the bowel is objectively clear — particularly in constipation-predominant and mixed IBS.
Pelvic floor dysfunction, specifically a condition called dyssynergic defaecation, is another significant and frequently overlooked cause. Rather than relaxing during a bowel movement, the pelvic floor and sphincter muscles contract, making complete evacuation difficult or impossible.
Rectocele — a bulge of the rectal wall into the vaginal wall — can physically trap stool and contribute to incomplete emptying, particularly in women with a history of vaginal delivery.
Internal haemorrhoids can produce a sensation of fullness or incomplete emptying even when the rectum is actually empty.
Constipation of any cause and rectal prolapse can also present with this symptom.
Is Incomplete Evacuation a Sign of Something Serious?
In most cases, incomplete evacuation is caused by a functional or structural condition that is not dangerous but is significantly affecting quality of life. However, the symptom always warrants proper clinical assessment, particularly if it is new, worsening, or accompanied by rectal bleeding, unexplained weight loss, or a change in stool calibre.
How Is Incomplete Bowel Emptying Investigated in Australia?
At Bowel Diagnostics and Therapy, your clinician will take a detailed clinical history and may recommend anorectal physiology testing, defaecating proctography, colonoscopy where clinically indicated, and endoanal ultrasound for structural sphincter assessment. This combination identifies the specific mechanism driving your symptoms.
What Treatments Are Available?
For pelvic floor dysfunction and dyssynergic defaecation, biofeedback therapy has strong clinical evidence and produces meaningful improvement in most patients.
For IBS-related incomplete evacuation, dietary modification, targeted medications, and gut-directed therapies are the foundation of management.
Rectocele repair may be appropriate in selected cases. Bowel retraining and laxative optimisation address constipation-related causes.
There is almost always something that can be done. You do not have to keep spending every morning on the toilet wondering why it never feels finished.
Frequently Asked Questions
-
The constant urge to go without being able to is often linked to IBS, pelvic floor dysfunction (dyssynergic defaecation), constipation, internal haemorrhoids, or rectocele. A clinical assessment including anorectal physiology testing can identify the specific cause and guide effective treatment.
-
Incomplete evacuation refers to the persistent sensation that the bowel has not fully emptied after a bowel movement. It is a recognised clinical symptom with several identifiable causes, and it is not something you have to manage indefinitely without investigation.
-
Yes. A condition called dyssynergic defaecation, where the pelvic floor and sphincter muscles contract rather than relax during a bowel movement, is a common and frequently overlooked cause of incomplete bowel emptying. It responds well to biofeedback therapy in most patients.
-
Treatment depends on the underlying cause. Biofeedback therapy is highly effective for pelvic floor-related causes. IBS-related incomplete evacuation responds to dietary modification and targeted medications. Bowel retraining and laxative optimisation help constipation-related causes. A clinical assessment is the first step to identifying the right treatment, book an initial consultation at Bowel Diagnostics & Therapy to take the first step.
