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...
Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion01:20

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...
Pharmacokinetics in Obese Patients: Drug Absorption and Distribution01:25

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...
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...
Binge Eating Disorders01:23

Binge Eating Disorders

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...
Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

Summary

Impulse control disorders (ICDs) are common in individuals with morbid obesity awaiting bariatric surgery. These conditions, including skin picking and compulsive buying, are more prevalent in those with a history of binge eating.

Area of Science:

  • Psychiatry
  • Bariatric Medicine
  • Clinical Psychology

Background:

  • Morbid obesity is a complex condition often associated with psychiatric comorbidities.
  • Impulse control disorders (ICDs) represent a significant diagnostic challenge in this population.
  • Understanding the prevalence of ICDs is crucial for effective pre-surgical evaluation.

Purpose of the Study:

  • To determine the prevalence of current and lifetime impulse control disorders (ICDs) in individuals seeking bariatric surgery.
  • To identify specific ICDs most frequently observed in this patient group.
  • To explore the relationship between binge eating patterns and the presence of ICDs.

Main Methods:

  • A cohort of 100 morbidly obese individuals undergoing pre-bariatric surgery evaluation was assessed.
  • The Structured Clinical Interview for DSM-IV (SCID) module for ICDs was utilized for diagnosis.
  • Participants were categorized based on the presence of current and lifetime ICDs, and binge eating behavior.

Main Results:

  • Nineteen percent of participants had at least one current ICD, while 27% met criteria for a lifetime ICD.
  • The most common ICDs included skin picking (8% current, 9% lifetime), compulsive buying (6% current, 8% lifetime), and intermittent explosive disorder (5% current, 10% lifetime).
  • Patients with regular binge eating (n=25) reported a significantly higher history of ICDs compared to those without binge eating.

Conclusions:

  • Impulse control disorders are highly prevalent among morbidly obese patients awaiting bariatric surgery.
  • A significant association exists between regular binge eating and a history of impulse control disorders in this population.
  • These findings underscore the importance of screening for ICDs in pre-bariatric surgery candidates, particularly those with binge eating behaviors.
