Systemic causes of abdominal pain

Area of Science:

• Gastroenterology and Internal Medicine
• Abdominal Symptomatology
• Systemic Disease Manifestations

Background:

• Abdominal symptoms often arise from intra-abdominal pathology.
• However, a significant number of cases are attributed to systemic and extra-abdominal conditions.
• Understanding these extra-abdominal causes is crucial for accurate diagnosis and effective management.

Purpose of the Study:

• To review the most important and common systemic and extra-abdominal diseases presenting with abdominal symptoms.
• To categorize these causes based on underlying mechanisms.
• To provide a comprehensive overview for clinicians managing patients with unexplained abdominal complaints.

Main Methods:

• Literature review of systemic and extra-abdominal diseases causing abdominal symptoms.
• Categorization of causes into metabolic/endocrine, hematologic, inflammatory, infectious, functional, and neurogenic.
• Synthesis of key findings regarding mechanisms and clinical presentation.

Main Results:

• Systemic diseases manifest abdominal symptoms through diverse pathophysiological pathways.
• Key categories identified include metabolic/endocrine disorders (e.g., diabetes, adrenal insufficiency), hematologic conditions (e.g., sickle cell disease, porphyria), inflammatory diseases (e.g., vasculitis), infections (e.g., Lyme disease), functional disorders, and neurogenic causes.
• Each category presents unique diagnostic challenges and therapeutic considerations.

Conclusions:

• Systemic and extra-abdominal diseases represent a critical differential diagnosis for abdominal symptoms.
• Recognition of these conditions prevents diagnostic delays and inappropriate intra-abdominal interventions.
• A broad clinical perspective is essential for comprehensive patient care.
