Mucus stools are usually yellow or clear in color and thin and jelly-like. Generally, mucus stools are divided into physiological mucus stools and pathological mucus stools. 1. Physiological mucus stool: If the patient is overly nervous, frightened and irritated, a small amount of mucus will appear in the feces under such circumstances, which is normal and can be regarded as physiological mucus stool. Generally speaking, mucus in feces is caused by intestinal secretion, which is yellow or transparent in color, and secretion of a small amount of mucus can help the stool to pass through the intestines smoothly. Therefore, a small amount of yellow or transparent mucus is normal. 2. Pathological mucus stools: Pathological cases usually have a large amount of mucus, which can be seen with the naked eye. This mucus is not completely mixed with the stool, usually adheres to the surface of the stool or exists in the form of thin jelly, and is often accompanied by other symptoms, such as bloody stool, pus, change in the color of the stool, abdominal pain, etc. If the patient has the above phenomenon, it is recommended to take prompt action. Patients who experience the above phenomena are advised to seek prompt medical attention to clarify the cause to avoid delaying the condition.
