Binge Eating Disorders01:23

Binge Eating Disorders

177
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...

Bulimia Nervosa01:30

Bulimia Nervosa

197
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...

What is Monogastric Digestion?

72.5K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Irritable Bowel Syndrome I: Introduction

393
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

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

426
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...

Anatomy of the Intestines01:23

Anatomy of the Intestines

74.1K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Area of Science:

  • Neuroscience
  • Microbiology
  • Psychiatry

Background:

  • Binge-eating disorder (BED) is prevalent, yet its underlying mechanisms remain unclear.
  • Emerging evidence implicates the gut microbiota and its communication with the brain via the gut-brain axis in BED pathogenesis.
  • Further mechanistic research is crucial for developing effective BED management strategies.

Purpose of the Study:

  • To propose a conceptual model integrating the gut microbiota into BED research.
  • To guide future research directions in understanding and treating BED.
  • To explore the role of gut microbiota in BED pathophysiology.

Main Methods:

  • This review synthesizes current research on the gut microbiota's role in BED.
  • It examines how diet-induced changes in gut microbiota affect key pathways in BED.
  • The review considers biological mechanisms linking gut microbiota to psychological effects in BED.

Main Results:

  • High consumption of hyper-palatable foods in BED reduces microbial diversity and increases inflammation.
  • Altered gut microbiota impacts pathways related to satiety, reward, impulsivity, and mood in BED.
  • Individual factors like genetics and stress can modulate the diet-microbiota-BED relationship.

Conclusions:

  • The gut microbiota is a significant factor in BED, influencing brain function and behavior.
  • Microbiota-targeted interventions, such as psychobiotics, show promise for future BED therapeutics.
  • The gut microbiota represents a novel and promising target for BED treatment development.
