Gastrointestinal dysfunction, including swallowing difficulties and constipation, is a common Parkinson's disease (PD) symptom. These issues stem from nervous system problems affecting digestion and bowel movements.

Area of Science:

  • Neurology
  • Gastroenterology
  • Movement Disorders

Background:

  • Gastrointestinal (GI) dysfunction is a prevalent and significant symptom in Parkinson's disease (PD).
  • Symptoms range from salivary issues and dysphagia to gastroparesis and constipation.
  • These dysfunctions can impact patient quality of life and disease management.

Purpose of the Study:

  • To outline the common gastrointestinal dysfunctions observed in Parkinson's disease.
  • To describe the specific features of these GI symptoms.
  • To highlight the potential impact of GI dysfunction on PD progression and treatment.

Main Methods:

  • Review of existing literature on gastrointestinal symptoms in Parkinson's disease.
  • Analysis of the pathophysiology linking PD to GI dysfunction.

  • Categorization of symptoms including salivary control, swallowing, gastric emptying, and bowel function.

    • Main Results:

    • Parkinson's disease frequently involves disordered saliva control, dysphagia (difficulty swallowing) in ~50% of patients, and gastroparesis.
    • Constipation is characterized by reduced bowel movement frequency and defecatory dysfunction.
    • These symptoms arise from both central and enteric nervous system impairments.

    Conclusions:

    • Gastrointestinal dysfunction is a core feature of Parkinson's disease, impacting multiple digestive processes.
    • Dysphagia and gastroparesis are significant symptoms that may relate to nervous system derangement.
    • Bowel dysfunction in PD results from delayed transit and impaired anorectal coordination, affecting treatment efficacy.
