Understanding the importance of mucus in our bodies is important when learning why orange mucus in stool is not a great sign. Mucus is an essential substance and necessary in helping the body function properly.

It is composed of a mixture of salts, mucin (a protein component), and water. Mucus is secreted into the digestive and respiratory system through cell linings.

Once it reaches the digestive and respiratory system, it serves the following functions:

Lubrication: Mucus helps to moisten and lubricate the linings located in the respiratory and digestive systems. It keeps the lining present in both body systems from drying up. It also helps reduce friction from the digestive system.

Digestion is a complex process, and the presence of mucus helps to oil the intestines, which are the digestion process engines. In the digestion process, mucus helps the food run through the digestive system in an effective manner.

Protection: Mucus also acts as a protection fluid. It acts as a mechanical barrier, which protects the delicate cells located in our intestine and stomach lining. The delicate and special cells in the stomach are responsible for the production of hydrochloric acid. Hydrochloric acid is corrosive and dangerous to these delicate cells.

To protect these delicate cells, the stomach walls secret thick mucus that acts as a barrier.

Defence: Mucus contains antibodies, vital proteins, and enzymes that help protect your body from bacterial organisms and assist in fighting off infections.

Therefore, the presence of mucus in stool is necessary. Nevertheless, there are some cases where the colour of mucus can change from white or colourless to another colour. The change of mucus colour in the stool is an indication that there is a problem with the digestive system.
