Even Infants and Young Children Can Experience Constipation – It Can Be Treated Effectively!

The etiology of constipation in pediatric populations exhibits a complex, multifactorial nature, encompassing a broad spectrum of pathophysiological mechanisms. Clinically, the following categories are distinguished: **functional constipation** – characterized by defecation disorders (referred to as dyschezia), frequently accompanied by secondary symptoms such as anal fissure bleeding (resulting from mechanical mucosal trauma), pain of varying severity, and abdominal distension; **psychogenic constipation** – triggered by situational factors (e.g., unsanitary toilet conditions, disciplinary punishments) or traumatic experiences (including sexual abuse); **dietary constipation** – associated with insufficient fiber intake and chronic fluid deficiency; **organic constipation** – arising from primary gastrointestinal pathologies (e.g., Hirschsprung’s disease, congenital rectal anomalies, acquired fistulas, anal fissures, hemorrhoids); **metabolic constipation** – linked to water-electrolyte imbalances (dehydration), cystic fibrosis, endocrine dysfunctions (hypothyroidism, adrenal insufficiency, potassium disorders); **neuromuscular constipation** – caused by hypotonia or underdevelopment of abdominal musculature (as seen in Down syndrome, cerebral palsy), muscular dystrophies, or spinal cord injuries (tumors, spina bifida); **iatrogenic constipation** – induced by pharmacotherapy (opioids, antidepressants, psychotropics, vincristine). A distinct category comprises **pseudo-constipation**, observed in eating disorders (anorexia, extreme weight-loss diets) or older exclusively breastfed infants. Particularly common are **habitual-functional constipations**, attributable to maladaptive defecation patterns. Diagnosis requires the presence of at least two of the following criteria (persisting for ≥8 weeks): stool frequency ≤2/week, episodes of fecal incontinence (≥1/week), voluntary stool retention, painful defecation or hard stools, rectally palpable fecal masses, historical evidence of voluminous bowel movements. Associated symptoms may include mood disturbances (irritability), reduced appetite, or premature satiety. The pathogenesis of habitual constipation is primarily influenced by **genetic predispositions**, **psychogenic factors** (stress, anxiety), **socio-environmental conditions** (e.g., lack of privacy), and **nutritional deficiencies** (suboptimal diet composition).

The management of pediatric constipation represents a protracted therapeutic intervention spanning one to two years, necessitating the coordinated efforts of a multidisciplinary clinical team. The initial phase prioritizes complete intestinal disimpaction of accumulated fecal matter, succeeded by sustained maintenance therapy incorporating tailored dietary modifications, structured physical activity regimens, pharmacological laxatives, biofeedback training (a technique enabling voluntary regulation of autonomic bodily functions), and psychological support services. Pharmacological interventions primarily utilize osmotic agents—including lactulose, polyethylene glycol (PEG), and sorbitol—supplemented by rectal osmotic preparations (sorbitol, glycerin suppositories), stimulant laxatives (e.g., senna leaf/fruit, bisacodyl—contraindicated in infants), and lubricant agents (mineral oil, liquid paraffin—also contraindicated in infants). Equally critical are evidence-based nutritional guidelines emphasizing adequate hydration, exclusion of constipating or gas-producing foods, and integration of high-fiber diets to enhance stool bulk, promote bowel regularity, and cultivate beneficial gut microbiota.
