Parkinson's disease (PD) is a neurodegenerative disorder primarily characterized by motor symptoms
such as bradykinesia, rigidity, rest tremor, and postural instability. However, visceral- symptoms are
also a significant part of the disease spectrum, with gastrointestinal (GI) manifestations being among
the most common and debilitating. This review is one of the recent literature on the gastroenterological
manifestations of PD. This includes dysphagia, esophageal motility disorders, gastroparesis, constipation,
pelvic floor dyssynergia, nausea and vomiting, contraindicated medications, and SIBO[small intestine
bacterial overgrowth].
