What is Mucus?
Mucus is a clear, bubbly, semi-solid, semi-liquid substance with whitish or yellowish tinch. Generally it is a jelly like substance showing trapped air in it. Mucus is mainly produced by the mucus membrane of inner epithelial lining of large intestine. As it is slippery in nature having jelly like consistency, it makes the inner lining of the intestine very smooth, thus acting as a lubricant, reducing the friction and helps in transportation of stool up to the anus.

Mucus is also produced by other organs in human body like lungs, nasal cavity. The mucus produced in lungs performs a function of trapping any inhaled foreign particle and thus prevents lungs from damage.

Pathological Conditions
In most of the cases there is a general balance between the secretion of every enzyme, chemicals in human body including mucus. A slight disturbance in this natural balance system can lead to erratic behavior of human organs. Same is the case when there is apparent mucus in stool. There are numerous causes related to the presence of abnormal amount of mucus in stool. It can be common symptom of ulcerative colitis (UC) or irritable bowel syndrome (IBS). It can be because of bacterial infection, bowel obstruction or anal fissure.

1. Ulcerative Colitis –
In this pathological condition the mucus membrane of epithelium lining of large intestine become inflamed, that ultimately result in development of Ulcers. These ulcers at later stage start bleeding and because of such wounds in the inner lining of intestine, production of pus and mucus takes place. This increase amount of mucus is then thrown out of body via stool.

2. Bacterial Infection –
Naturally certain amounts of bacteria and yeasts are present in human intestine to facilitate the digestion process. Introduction of foreign particles may cause the imbalance. Bacteria like Salmonella, Campylobacter, Shigella, or Yersinia, are the main culprit of the bacteria infection. This pathological condition of bacterial infection can cause fever, diarrhea or abdominal cramps along with increased mucus in stool.

Most of the times no specific treatment is required and the situation will resolve on its own but should be monitored continuously. If situation doesn’t improve over a period then it can be serious and need treatment with the help of antibiotics. It is always better to consult physician.

3. Bowel Obstruction –
Bowel obstruction is one of the commonly found reasons behind presence of mucus in stool. It is associated with severe abdominal cramps, abdominal distention, constipation and vomiting. Bowel obstruction can be because of various reasons like loosing gastric hormone balance, low water intake, increased yeast formation. In some cases it can be because of anatomical obstruction and needed to get operated to cure the thing.

4. Irritable Bowel Syndrome (IBS) –
As with ulcerative colitis, in irritable bowel syndrome, there is increase production of mucus by the epithelial lining of intestine which is then passed through stools. It has been observed that with diarrhea pre-dominant irritable bowel syndrome, more mucus formation is associated.

5. Crohn’s Diseases (CD) –
There is a lesser amount of mucus production associated with Crohn Disease. Mucus in stool is also associated with anal fissure.

If the color of mucus present in stool is whitish then it is a good indication of inflammation of the intestine. Mucus in stool is the symptoms oftenly occurred along with diarrhea and constipation. Although the passage of mucus in the stool is not generally a dangerous or alarming situation, it should be mentioned to your doctor. The presence of mucus without any significant cause should be brought in the notice of your physician immediately.

Normally, the most common reasons behind presence of mucus are food allergies, sensitivities and bacterial overgrowth. They can be easily cured over the certain time with the help of inclusion of specific dietary elements and supplements. If the problem is associated with bacterial overgrowth the situation gets worsen with the intake of sugar or the substances containing lactose sugar like Pasta, Bread, Milk, etc. on the other hand people suffering from food allergies react to specific foods.
