What causes mucus in feces?

If you’ve ever experienced finding strange objects in your poop, such as mucus, you may be wondering whether it’s something to worry about. Well, don’t get alarmed just yet; the existence of mucus is a normal thing that ensures normal bowel movements (1).

Mucus, normally found in our intestines and rectum walls secretes fluid that lubricates the large intestine providing a slippery tunnel for our waste to slide through without any irritation or pain.

However, if there’s an excessive build-up of mucus in your stool accompanied by other symptoms such as cramps and abdominal pains, then it could be pointing to an underlying condition that requires attention from healthcare professionals.

So what are some of these conditions? Keep reading!


An infection happens when harmful microorganisms such as bacteria or viruses invade the body leading to inflammation.(4)

In bacterial infections like salmonella and shigellosis – which attack the digestive system- excess production of mucus loaded with white blood cells fights off similar infections causing diarrhea(5). However,chlamydia;a prevalent sexually transmitted disease might also present with mucoid discharge.

For viral infections like norovirus or rotavirus on its own does not produce anything apart from vomiting and diarrhea but sometimes mixed gram-negative facultative anaerobic bacteria can overgrow causing enterocolitis presenting with more exudate concentrating at times mainly in colonic isolations confusing non-healthcare practitioners into thinking there exists solely a pathogenic root cause rather than secondary complications.

Poor Nutrition

When people consume diets insufficient with vital nutrients required for digestion processes or consume alarming amount triggering rapid peristaltic activity excessive peristalsis contributing obscure amount hence mistakable items whitish-green/mucilaginous cloud-fluid content.
So,wishlist foodies immediately prioritize dietary modifications especially adding magnesium vegetables can regulate spasms in small intestines. Fiber consumption through the intake of whole grains, vegetables like spinach or kale, and fruits prevents moisture loss from feces preventing mucus build-up(6).

Irritable Bowel Syndrome (IBS)

IBS is a disorder affecting the large intestine resulting in bowel movement disturbances such as diarrhea, constipation,crampons,bloating,gas,and fatigue.Wind/bore syndromemeasuring wind volume can bring much-needed relive.
Since IBS affects different people differently mostly due to variations in sensitivity towards certain food groups high lists of intolerance include sweeteners e.g lactose/monosaccharide galactose specific;grains containing gluten(mostly non-celiac caused),spices,chilies,salicylates,& caffeine.Regular oral ingestion of phytotherapeutics drugs also helps especially those boosting serotonin production.

Crohn’s Disease

It’s among several medical conditions broadly known as inflammatory bowel diseases(IBD) Crohn’s disease primarily affects any part of your digestive tract snaking past our mouth to anus unlike another type- ulcerative colitis only presenting at colon’s lining. Basically,a patient with CD presents with complex symptoms including blood/mucus seeable on excrement traces lesions-fissures often occurring around perianal areas,microperforations between intestinal parts presenting stool mixed pus-filled content,dryness/thinness inflammation-risks occlusion,midabdominal cramps requiring urgent surgical procedures.(2)

Here are some facts you didn’t know about crohns’r

1) It was named after Dr.Burrill Bernard Cohn-the man who discovered it.
2) 56% females vs 44% males have experienced its onset by age 35years old
3) There exists no permanent cure for this condition though healthy living habits & dietary management along radical surgery reparations forms logical approach to subdue painful flare-ups

Ulcerative Colitis (UC)

UC as mentioned above only specifically presents with the large intestine lining inflammation excess protein accumulating causing rectum ulcers accompanied by blood/mucous and not throughout other digestive tract regions like CD.(3)
During gross endoscopic examinations-the most common method used to detect UC-every inflamed pink lesion seen is co-extensive with a mucosal area characterized predominantly by crypt abscesses formed mainly after direct contact of bacteria will colonise any compromised part.
At this stage,patients might require the addition of anti-inflammatory drugs and corticosteroids but when 2-3 cycles do nothing for them surgical interventions are needed for long term stability.

Colon Cancer

Though rare, colon cancer can cause mucus in stool alongside bright red blood although more frequently than not;occurring because malignant tumors act as catalysts stimulating increased production of bodily fluids. So,don’t let those that talk about check-ups be “anal” keep making conscious health lifestyle choices and respect your family’s medical history. When diagnosed on time colorectal surgery can prolong life-expectancy rates.

Additionally, people who have inflammatory bowel disease (IBD) such as ulcerative colitis or Crohn’s Disease may experience autoimmune reactions which further increases mucosal secretion contributing more significant clumps in their fecal matter.


Mucus in feces itself has no serious implications unless it’s accompanied by unidentifiable foreign objects apart from undigested food particles changes color,t consistency during normal hued outcomes thus avoiding stress-induced constipation/worry leading to oxytocin suppression(main pleasure hormone). Noteworthy being able to catch(melena/GI bleeding),prioritizing hydration,nutritionial balance along active lifestyles can promote an ideal gut environment enriching fiber breakdown-absorption fluid-regulation hence minimizing mucus formation/overgrowth enforcing good public health practices.

As stated earlier,this information does not substitute professional medical advice,contact your healthcare provider for any concerns. Now that you’ve come to the end of our journey,hopefully many shall stand in awe of the depths they could find solace instead of embracing ignoramus fatalism about healthy habits and digestive systems.
Catch next time as we dive deeper into pulsatile secretions within fecal matter- I promise you it will be a sight to see.

Stay curious people!
