Self-Evaluation: Self-Enhancement and Self-Verification

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Area of Science:

Gastroenterology
Functional Gastrointestinal Disorders

Background:

Rumination syndrome is a functional gastroduodenal disorder characterized by effortless, repetitive regurgitation of food.
It is often overlooked by physicians, despite characteristic clinical features.

Purpose of the Study:

To describe the clinical features, diagnostic methods, and treatment of rumination syndrome.
To highlight the diagnostic utility of postprandial high-resolution esophageal impedance manometry.

Main Methods:

Clinical observation and review of diagnostic findings.
Utilizing postprandial high-resolution esophageal impedance manometry to detect gastric pressurization and regurgitation.

Main Results:

Characteristic symptoms include effortless regurgitation, rechewing, and reswallowing or spitting.
High-resolution esophageal impedance manometry can identify gastric pressurization (>30 mmHg) and proximal esophageal food return, a pathognomonic sign.

Conclusions:

Rumination syndrome diagnosis is primarily based on characteristic symptoms and confirmed by esophageal impedance manometry.
Behavioral therapy, particularly diaphragmatic breathing, is the cornerstone of treatment, with further research needed for refractory cases and biofeedback efficacy.
