Bulimia Nervosa

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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Anorexia Nervosa

Anorexia Nervosa

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
Symptoms and Physical Effects
Individuals with anorexia nervosa commonly exhibit extreme...

Pathophysiology of Vomiting

Pathophysiology of Vomiting

Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through interaction...

Assessment of the Gastrointestinal System II: Health Perception Pattern

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:

Binge Eating Disorders

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...

Summary

Most adults with cyclic vomiting syndrome (CVS) are at risk of malnutrition, despite potential overweight or obesity. Early nutritional assessment by a Registered Dietitian Nutritionist (RDN) is crucial for managing this condition.

Area of Science:

Gastroenterology
Nutritional Science
Clinical Medicine

Background:

Cyclic vomiting syndrome (CVS) frequently impacts nutritional status due to recurrent nausea and vomiting.
Systematic data on nutritional status in adults with CVS are limited.

Purpose of the Study:

To evaluate the nutritional status of adults diagnosed with cyclic vomiting syndrome (CVS).
To assess the effectiveness of validated screening tools in identifying malnutrition risk in CVS patients.

Main Methods:

A prospective study involving 80 adults diagnosed with CVS according to Rome IV criteria.
Nutritional status assessed using Patient-Generated Subjective Global Assessment Short Form (PG-SGA-SF), PG-SGA by a Registered Dietitian Nutritionist (RDN), and Malnutrition Screening Tool (MST).

Main Results:

70% of participants were at risk of malnutrition based on PG-SGA-SF, with 51% identified by MST.
Despite malnutrition risk, 27% were obese and 20% overweight; BMI did not differentiate nutritional status.
The PG-SGA-SF showed high sensitivity (100%) and specificity (71%) for detecting malnutrition.

Conclusions:

The majority of adults with CVS exhibit malnutrition, necessitating referral to an RDN.
Body Mass Index (BMI) is not a reliable screening tool for malnutrition in CVS.
Further research is needed to understand the mechanisms contributing to obesity in CVS.
