Summary
This review found conflicting evidence on the link between functional defecation disorders (FDDs) and childhood obesity. More high-quality research is needed to confirm or refute this association in pediatric populations.
Area of Science:
- Pediatric Gastroenterology
- Public Health
- Obesity Research
Background:
- Functional defecation disorders (FDDs) are common in children.
- An association between FDDs and overweight/obesity has been suggested in several studies.
- Understanding this relationship is crucial for pediatric health management.
Purpose of the Study:
- To systematically review and synthesize existing evidence on the association between FDDs and overweight/obesity in children.
- To evaluate the quality of studies investigating this relationship.
Main Methods:
- A comprehensive search of PubMed, Medline, and Embase databases was conducted.
- Included were prospective and cross-sectional studies of children aged 0-18 years.
- Data extraction and quality assessment were performed independently by two authors.
Main Results:
- Eight studies were included, with varying designs and quality (7/8 rated fair or poor).
- Some studies indicated a higher prevalence of FDDs in obese children and higher rates of overweight/obesity in children with FDDs.
- However, results were heterogeneous and conflicting, with one population-based study showing a significant association.
Conclusions:
- The current evidence regarding the association between FDDs and childhood overweight/obesity is conflicting and of variable quality.
- This systematic review could not confirm or refute the suspected association due to study heterogeneity and limitations.
- Further high-quality research is warranted to clarify this relationship.

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

939
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

01:26Physiology of the Gastrointestinal System III: Elimination
1.8K
The gastrointestinal elimination process involves a complex interplay of neural and hormonal mechanisms that coordinate the final waste removal from the body. This intricate operation encompasses the absorption of water and electrolytes, vital for transforming the remaining indigestible food matter into feces. The large intestine is pivotal in water and electrolyte absorption, forming feces from unabsorbed minerals, undigested food, bacteria, bile pigments, and shed epithelial cells. Essential...

01:21Drug Dosing: Obese Patients
329
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...
