Functional constipation in pediatric patients: an observational study in southern Brazil.

Background: Functional constipation is characterized by a set of symptoms including hardened stools, abdominal discomfort, a tendency to retain stools, and eventual fecal incontinence. This condition negatively affects the quality of life of the affected individuals and has potential psychosocial repercussions.

Objectives: To assess the epidemiological, clinical, and therapeutic aspects of functional constipation in patients treated at a pediatric gastroenterology outpatient clinic.

Design and setting: Descriptive observational study with a quantitative approach using secondary data collected from the medical records of a pediatric gastroenterology outpatient clinic in Criciúma between 2018 and 2023.

Methods: This study was approved by the Human Research Ethics Committee of the Universidade do Extremo Sul Catarinense (Unesc) under number 6.788.465. Sociodemographic, clinical, and therapeutic variables were evaluated in 67 patients aged 0-18 years who were diagnosed with Functional Constipation (ICD K590) during the study period. Data were analyzed using descriptive statistics in the Statistical Package for the Social Sciences (SPSS), version 25.0.

Results: There was a predominantly female profile (36; 53.7%), with an average age at diagnosis of 7.75 years (± 3.96). The main symptoms included abdominal pain (52, 77.6%) and hardened stools (42, 62.7%), with an average interval of 4 days between bowel movements. Treatment consisted of macrogol prescriptions (60, 89.6%), with most patients showing complete symptom improvement (49, 73.1%).

Conclusion: Analysis of medical records highlighted the need for continuous monitoring and targeted interventions, considering the variability of symptoms and individual characteristics of patients.
