In the healthy intestine, rhythmic contractions of the intestinal wall muscles push food through the digestive tract. Ileus is a serious disease in which the intestine paralysis occurs.
Bacteria in the partially digested food (that is left in the intestine) create gas that expand the intestines and the abdominal cavity. Swollen belly presses the chest (thorax) and makes breathing more difficult. With strong constipation, a patient can get fever and often vomit the fluid with an unpleasant smell. During the onset of illness, the patient feels a dull, persistent abdominal pain. Pain can quickly disappear, but this is not a sign of improvement and the disease can cause death is a person postpones the treatment.
Ileus, at a certain level, occurs after many operations in the abdominal cavity, but it is solved in a hospital so routinely that you will probably not even find out that you had it. Otherwise, ileus may be caused by a serious condition, such as a perforated ulcer, but a person who has it is already severely ill and needs immediate medical intervention. Successful treatment of the underlying condition should also cure ileus.
