Insights

Functional constipation (FC) in children is linked to both obesity and undernutrition, particularly in Asian populations. Further research is needed to understand the cause-and-effect relationship.

Area of Science:

  • Pediatric Gastroenterology
  • Nutritional Science
  • Public Health

Background:

  • Functional constipation (FC) and malnutrition are prevalent childhood diseases with significant long-term health implications.
  • Understanding the relationship between FC and nutritional status is crucial for effective pediatric healthcare.
  • This study systematically reviews the existing literature to analyze the connection between FC and malnutrition in children.

Approach:

  • A comprehensive systematic review and meta-analysis was conducted.
  • Searches were performed across major databases including PubMed, AAP, Cochrane, and ClinicalTrials.gov.
  • Eighteen studies involving 33,410 children were analyzed using a random-effects model and Newcastle-Ottawa Scale for bias assessment.

Key Points:

  • A significant association was found between FC and overweight/obesity (OR = 1.75, P = 0.02) and undernutrition (OR = 2.38, P < 0.001), especially in Asian countries.
  • In Asian populations, normal weight was more common in children without FC (OR = 0.54, P < 0.001).
  • The link between FC and short stature remains inconclusive.

Conclusions:

  • FC is correlated with both increased prevalence of overweight/obesity and undernutrition in children.
  • Further research is warranted to explore the causal relationship between FC and these nutritional states.
  • Investigating the potential benefits of FC treatment on nutritional outcomes is recommended.

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

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.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives01:22

Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives

Laxatives enhance bowel movements and alleviate constipation. They augment the stool's bulk, stimulate intestinal muscle contractions, draw water into the intestines, or soften the stool. There are five key types of laxatives: bulk laxatives, stimulant laxatives, osmotic laxatives, stool softeners, and lubricant laxatives.
Bulk-forming laxatives, such as psyllium, methylcellulose, and polycarbophil, absorb water in the intestine, increasing stool bulk and promoting bowel movement. This...

Assessment of the Gastrointestinal System II: Health Perception Pattern01:29

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:
