Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
Bulimia Nervosa01:30

Bulimia Nervosa

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...
Drug Dosing: Obese Patients01:21

Drug Dosing: Obese Patients

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...
Drugs for Treatment of Constipation-Predominant IBS01:21

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...
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,...
Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Area of Science:

  • Pediatric Gastroenterology
  • Adolescent Health
  • Obesity Research

Background:

  • Gastrointestinal symptoms and overweight associations are increasingly studied.
  • Limited research exists on overweight and constipation in community-based adolescent samples.
  • This study addresses the gap by examining constipation prevalence and its link to overweight in adolescents.

Purpose of the Study:

  • To determine the prevalence of constipation in a community-based sample of adolescents.
  • To analyze the association between being overweight and constipation in this population.
  • To investigate the relationship between overweight and fecal incontinence in constipated adolescents.

Main Methods:

  • A cross-sectional study involving 1,077 adolescents from five schools in Sao José dos Campos, Brazil.
  • Constipation defined using modified Rome III criteria.
  • Overweight defined as body mass index (BMI) at or above the 85th percentile for age and gender.

Main Results:

  • Constipation prevalence was 18.2% (196/1077).
  • No significant difference in constipation prevalence was found between males and females, or between age groups (<14 and ≥14 years).
  • Overweight prevalence was 13.5% (145/1077). Constipation prevalence was similar in overweight (19.4%) and non-overweight (18.0%) adolescents (p=0.764).
  • Fecal incontinence was more frequent in overweight constipated adolescents (37.0%) compared to non-overweight constipated adolescents (8.5%) (p=0.005).

Conclusions:

  • Constipation is highly prevalent among the studied adolescents.
  • No direct association was found between being overweight and constipation.
  • A significant association exists between being overweight and fecal incontinence in adolescents with constipation.
