“…The association between functional constipation and hypohydration in school-aged girls is consistent with a previous case-control study conducted by our group (13). It suggested a high urinary osmolality in girls with severe functional constipation treated at a pediatric gastroenterology outpatient clinic (13). Hypohydration may be associated with high colonic reabsorption of water from the fecal mass, increased stool hardness, and decreased number of defecations (5,12).…”

“…Hypohydration may also increase the reabsorption of water from the fecal mass, increase stool hardness, and decrease the number of defecations (5,12). A previous case-control study by our group suggested that pediatric patients with severe functional constipation have low fluid intake and high urinary osmolality (13).…”

This school-based, cross-sectional study aimed to evaluate whether hypohydration is related to functional constipation and physical activity in school-aged children. The study included 452 students aged 6–12 years. Hypohydration, defined as urinary osmolality >800 mOsm/kg, was more prevalent (P = 0.002) in boys (72.1%) than in girls (57.5%). The difference in the prevalence of functional constipation according to sex (20.1% in boys and 23.8% in girls) was not statistically significant (P = 0.81). In bivariate analysis, functional constipation was associated with hypohydration in girls (odds ratio = 1.93, 95% confidence interval: 1.07–3.49), and multiple logistic regression did not reach statistical significance (P = 0.082). Low proportions of active commuting to school in both sexes were associated with hypohydration. However, there were no associations between functional constipation, active commuting to school, and physical activity scores. In conclusion, multiple logistic regression did not demonstrate an association between hypohydration and functional constipation in school-aged children.

“…Fluid intake. Insufficient fluid intake or excessive fluid loss due to severe diarrhea, vomiting, or fever may lead to the hardening of stools (97). This applies particularly to infants, who are more susceptible to dehydration because of their small body weight and high turnover of fluids.…”

Dietary factors may play an important role in the generation of symptoms in children with disorders of gut-brain interaction (DGBIs). Although dietary modification may provide successful treatment, there is a relative paucity of controlled trials that have shown the effectiveness of dietary interventions. This study is a narrative review that explores the existing literature on food and pediatric DGBIs. The following have been shown to be beneficial: (i) in infants with colic, removing cow's milk from the infant's diet or from the maternal diet in those who are breastfed; (ii) in infants with regurgitation, adding thickeners to the formula or removing cow's milk protein from the infant's diet or the maternal diet in those who are breastfed; and (iii) in children with pain-predominant DGBIs, using soluble fiber supplementation or a low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols diet. In children with functional constipation, there is no evidence that adding fiber is beneficial. Given that most dietary interventions include restriction of different foods in children, a thoughtful approach and close follow-up are needed.

“…Patients undergoing cardiac surgery need to be treated with diuretics and reduce water intake. The reduction of body water may increase the reabsorption of water in feces and thus increase stool hardness and reduce frequency of defecation [Boilesen 2021]. The decline of gastrointestinal motility in patients with cardiothoracic surgery also leads to the long retention time of feces in the intestinal tract, and the excessive absorption of water in the feces, which will lead to stool hardening and defecation difficulty [Włodarczyk 2021;Zoumprouli 2017].…”

Background: Defecation delay is a common symptom in patients after tricuspid valve replacement (TVR). Previous studies have demonstrated that defecation delay was associated with worse clinical outcomes of critically ill patients. Our study aimed to investigate the incidence and risk factors of defecation delay in patients after TVR and its adverse clinical outcomes. Methods: A retrospective study was conducted in 206 patients undergoing TVR under cardiopulmonary bypass from May 2005 to July 2021. According to the first postoperative defecation time after surgery, patients were divided into the delayed group (>3 days) and control group (≤3 days). Baseline characteristics and preoperative, intraoperative, and postoperative data were collected to investigate the clinical outcomes of defecation delay. Results: Among the 206 patients, 51.9% (107/206) cases were classified into the defecation delay group. Univariate analysis showed that age (P = 0.043), preoperative platelets (PLT) (P < 0.001), cardiopulmonary bypass (CPB) time (P = 0.013), minimum rectal temperature (P = 0.042), and the use of prokinetic drugs (P = 0.015) were significantly different in the two groups. In addition, the perioperative adverse events in the defecation delay group were significantly higher than that of the control group. Logistic regression analysis indicated that the mortality of patients was associated with postoperative renal dysfunction (P = 0.047) and postoperative respiratory failure (P = 0.004) but was not associated with defecation delay (P > 0.05). Conclusion: Patients with defecation delay after TVR were more likely to appear adverse events, however, defecation delay was not associated with mortality after TVR.
