Health Conditions that Cause Mucus in Stool. A sudden onset of mucus in the stool, accompanied by urgent diarrhea, cramping, fever, and blood in the stool may be indicative of a bacterial infection. If you are having any of these symptoms, contact your physician immediately.
Atelectasis, or localized obstruction of the lungs that may result from mucus plug obstruction, can occur resulting to the collapse of a portion of the lungs. This is enumerated by the study published by Respiratory Care in September 2007.
Before labor, this mucus plug is expelled allowing the baby to pass through the cervix during labor and birth. Passing a mucus plug is a sign that your cervix is dilating and that your body is preparing for birth. Labor could be hours, days, or even weeks away as the cervix gradually opens. The mucus plug is usually clear, slightly pink or blood tinged in color. It can be stringy mucus or a sticky discharge. Some women might not notice the loss of their mucus plug since there is already an increase in vaginal discharge during pregnancy.
