The Reality of Fecal Stasis and Incomplete Evacuation Sensation

Hello. Today, I would like to talk about two concepts that many people find confusing.

Tenesmus and Mucoid Impaction (Sukbyeon), Two Confusing Concepts

Tenesmus, the feeling of incomplete evacuation even after a bowel movement, and mucoid impaction (sukbyeon), the belief that old residue has accumulated inside the intestines. These two concepts may seem similar on the surface, but they are actually completely different.

Many people feel that something is left behind and not refreshed after visiting the bathroom, leading them to think, "Is it because of mucoid impaction?" However, there is a distinct pathology behind this feeling. Today, we will examine those differences in detail.

1. Tenesmus – A Functionally Existing Disorder

Medically, the feeling of incomplete evacuation is called "Tenesmus." It is characterized by an incomplete feeling as if something remains in the rectum or anus after defecation, and an unpleasant sensation of a continuous urge to defecate.

Main Causes:

• Hypersensitivity of rectal sensation
• Decreased or inefficient intestinal peristalsis
• Incomplete opening of the sphincter
• Accompanied by Irritable Bowel Syndrome (IBS)
• Psychological factors (anxiety, obsession, etc.)

All these factors work complexly to induce a sensation that the bowel is not empty even when it actually is. This is a functional disorder with a clear possibility of diagnosis and is a symptom that is subject to treatment.

2. Mucoid Impaction (Sukbyeon) – A Symbolic Concept with Unclear Pathological Reality

The concept of mucoid impaction is closer to a folk belief that "old stool sticks to the walls of the intestines and causes toxins," and it is not recognized as an official medical diagnosis in modern medicine.

Misconceptions regarding mucoid impaction:

• The form of mucoid impaction is not observed during endoscopy
• Descriptions of black residue sticking to the intestinal mucosa are exaggerated
• Claims that removing mucoid impaction solves all diseases are unscientific

Occasionally, residual stool may be seen in an endoscopy where bowel preparation was insufficient, but this is simply a state of incomplete evacuation and is difficult to view as a reality where toxins have accumulated.

3. Why is it mistaken for mucoid impaction?

Because tenesmus is actually a very unpleasant and frustrating sensation, many people interpret the cause as "stool remaining somewhere in the intestines."

Additionally, because people feel a sense of relief and lightness in the intestines after following a healthy diet, fasting, or detox therapy, the misconception arises that "mucoid impaction has been removed."

However, in reality, this is the result of functional intestinal recovery as irritating foods decrease, peristalsis is restored, inflammation of the intestinal mucosa subsides, and the intestinal microbial environment stabilizes. It is not that "mucoid impaction was removed," but that "the hypersensitive intestines have recovered."

4. Recovery of Intestinal Function is More Important than Mucoid Impaction

What we should focus on is the health of the mucosa, normalization of intestinal movement, microbial balance, and stability of the sensory nervous system. Rather than methods of detoxing or removing black residue, restoring the physiological function of the intestines itself is the fundamental solution.

Tenesmus is an actual functional disorder and a target for treatment. Mucoid impaction should be accepted as a folk concept—a symbol rather than a reality. If you have chronic tenesmus or discomfort during defecation, the correct answer is to accurately diagnose the cause and approach it in a direction that restores the intestines.

Thank you.
