Gender-related differences in dyspepsia: a qualitative systematic review

Area of Science:

• Gastroenterology
• Clinical Epidemiology
• Gender Studies

Background:

• Functional gastrointestinal (GI) disorders are more prevalent in women than men.
• Research on gender disparities in functional GI disorders is increasing, with prior focus on irritable bowel syndrome.
• Gender differences in other functional GI disorders remain less understood.

Purpose of the Study:

• To systematically review existing literature on gender-related differences in patients diagnosed with dyspepsia.
• To synthesize findings on the clinical epidemiology and pathophysiology of dyspepsia concerning gender.

Main Methods:

• Searched MEDLINE, HealthSTAR, and PsycINFO databases for English-language articles on dyspepsia (1966-2001).
• Included epidemiologic studies, clinical trials, and review articles.
• Summarized findings within biological and psychosocial frameworks; statistical analysis was not feasible due to study heterogeneity.

Main Results:

• Most studies lacked detailed gender analysis beyond demographics.
• Few consistent gender differences were statistically significant.
• Potential differences in symptom patterns, pain perception, and antinociceptive mechanisms between genders were noted but unconfirmed.

Conclusions:

• Further research is needed to explore gender-related differences in dyspepsia epidemiology and their clinical significance.
• Well-designed, population-based studies with consistent dyspepsia definitions are required.
• Investigating gender-specific prevalence and management patterns of dyspepsia is crucial.
