What is a known cause of paralytic ileus?

Paralytic ileus is a condition characterized by the loss of peristalsis in the intestines, leading to the inability to transit intestinal contents. Abdominal surgery is a well-recognized cause of this condition. During such surgeries, manipulation of the intestines and the handling of the gastrointestinal tract can disrupt normal motility. Postoperative ileus is a common occurrence, as the anesthetic agents and the stress of surgery can transiently halt intestinal activity.

Other factors like excessive exercise, chronic dehydration, and long-term antibiotic use do not commonly lead to paralytic ileus in the same direct manner. While dehydration can contribute to reduced bowel motility, it is more often associated with other gastrointestinal issues rather than being a primary cause of paralytic ileus. Long-term antibiotic use may induce changes in gut flora, which can lead to other complications but is not a direct cause of paralytic ileus.
