Data were analyzed univariately and presented as frequency distributions and percentages. Results: Based on gender, the majority of respondents were female (27 respondents (52%), aged 18–65 years (59.61%). The most common clinical symptoms were fecal retention (83%), abdominal pain (81%), abdominal distension (63%), vomiting (37%), nausea (35%), and flatus retention (33%). Conclusion: Obstructive ileus most commonly occurs in people of productive age to old age, with a balanced gender distribution. The dominant clinical symptoms are fecal retention and abdominal pain.
