Alexithymia and functional gastrointestinal disorders (FGID).

Area of Science:

• Psychosomatic Medicine
• Gastroenterology
• Clinical Psychology

Background:

• Functional gastrointestinal disorders (FGID) are common conditions often linked to psychological factors.
• Alexithymia, characterized by difficulty identifying and describing emotions, is frequently observed in FGID patients.
• Understanding the interplay between alexithymia, demographics, and FGID symptom severity is crucial for effective management.

Purpose of the Study:

• To investigate alexithymia symptoms in patients with FGIDs compared to healthy controls.
• To examine the relationship between demographic variables, alexithymia, and gastrointestinal symptom severity.
• To explore the influence of educational level on alexithymia in FGID patients and controls.

Main Methods:

• A sample of 237 individuals (129 FGID patients, 108 healthy controls) was recruited.
• Participants completed the Toronto Alexithymia Scale (TAS-20) and Gastrointestinal Symptoms Rating Scale (GSRS).
• Data were analyzed using MANOVA, correlation coefficients, and Fisher's z-transformation.

Main Results:

• FGID patients reported significantly more alexithymia symptoms and greater gastrointestinal symptom severity than healthy controls.
• A significant association was found between educational level and alexithymia dimensions (difficulty identifying/describing feelings) in both groups.
• No significant difference in the relationship between education and alexithymia was observed between FGID patients and controls.

Conclusions:

• Patients with FGIDs demonstrate higher alexithymia scores and more severe somatic symptoms compared to healthy individuals.
• Increased educational attainment correlates with a reduced risk of alexithymia, potentially due to enhanced emotional processing abilities.
• These findings highlight the importance of addressing alexithymia in FGID management and suggest education as a potential protective factor.
