Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

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...

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...

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...

Depressive Disorders: Etiology

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Anorexia nervosa: recent investigations.

Annual Review of Medicine

|January 1, 1978

Summary

This review details diagnostic criteria and recent studies on anorexia nervosa, including endocrine and hematological findings. Current research describes the disorder but hasn't pinpointed its cause, necessitating further investigation.

Area of Science:

Endocrinology
Psychiatry
Internal Medicine

Background:

Anorexia nervosa is a complex eating disorder with significant physical and psychological manifestations.
Understanding the underlying pathophysiology is crucial for effective treatment.

Purpose of the Study:

To review and synthesize recent findings related to the diagnosis and biological underpinnings of anorexia nervosa.
To highlight the current state of knowledge regarding the etiology of anorexia nervosa.

Main Methods:

Comprehensive literature review of recent studies.
Analysis of typological diagnostic criteria.
Examination of hematological, lipid, electrolyte, gastrointestinal, and electrocardiographic data.
Review of endocrine investigations (thyroid, adrenal, gonadotropin, growth hormone, catecholamines).

Main Results:

Descriptive criteria for anorexia nervosa have been refined through various studies.
Hematological, lipid, electrolyte, gastrointestinal, and ECG findings are characteristic but not causative.
Endocrine studies reveal alterations in thyroid, adrenal, gonadotropin, growth hormone, and catecholamine axes.
No single hypothesis for the etiology of anorexia nervosa is supported by current evidence.

Conclusions:

Recent research has enhanced the descriptive criteria for anorexia nervosa.
The etiology of anorexia nervosa remains multifactorial and not fully elucidated.
Further research is required to link anorectic behaviors with observed endocrine and catecholamine changes.
