What Is Fecal Impaction?
Fecal impaction happens when a large, hard mass of stool becomes lodged in the rectum, making it impossible to pass bowel movements naturally. Unlike routine constipation, the blockage won't clear without medical intervention and can lead to pain, swelling, and other complications if left untreated.
Common Causes and Risk Factors
Ongoing constipation or frequent straining
Low-fiber diet and inadequate fluid intake
Medications such as opioids or anticholinergics
Reduced mobility or neurological disorders
Advanced age (more common in seniors)
Signs and Symptoms
Pain or bloating in the abdomen
Feeling of fullness or pressure in the rectum
Small, watery stool leaking around the obstruction
Nausea, loss of appetite, or general discomfort
Difficulty passing gas
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your bowel habits, diet, fluid intake, medications and overall medical history. He then performs a gentle abdominal exam followed by a digital rectal exam to feel for hard, impacted stool.
Imaging Studies
Abdominal X-ray or ultrasound to confirm the presence, size and location of the impaction.
Laboratory Tests
Basic blood work to check for dehydration, electrolyte imbalances and any signs of infection or inflammation.
Further Evaluation (if needed)
In rare or complex cases, a CT scan or endoscopic evaluation may be used to assess complications and guide treatment.

Frequently Asked Questions
What's the difference between fecal impaction and constipation?
Constipation means infrequent, hard, or painful bowel movements. Fecal impaction occurs when a large, hard mass of stool is stuck in the rectum and cannot be passed without medical intervention.
What is the ICD-10 code for fecal impaction?
The ICD-10 code for fecal impaction is K56.41. This code is used for insurance billing and medical record documentation.
Can I still poop if I'm impacted?
Sometimes you may pass small amounts of watery stool around the blockage, but the hard mass itself won't move without treatment.
When should I see a doctor?
Seek help right away if you have persistent belly pain, can't pass stool or gas, experience nausea or vomiting, or notice rectal bleeding.
How can I prevent fecal impaction?
Stay hydrated, eat a high-fiber diet, exercise regularly, and establish a consistent bathroom routine to keep stool soft and moving.
Is fecal impaction dangerous?
Yes. If untreated, it can lead to ulcers, tears in the rectum, or even perforation of the bowel, which can be life-threatening.
