Nutritional considerations in the patient with gastroparesis.

Gastroparesis, or delayed gastric emptying, has many origins and can wax and wane depending on the underlying cause. Not only do the symptoms significantly alter quality of life, but the clinical consequences can also be life threatening. Once a patient develops protracted nausea and vomiting, providing adequate nutrition, hydration, and access to therapeutics such as prokinetics and antiemetics can present an exceptional challenge to clinicians. This article reviews the limited evidence available for oral nutrition, as well as enteral and parenteral nutritional support therapies. Practical strategies are provided to improve the nutritional depletion that often accompanies this debilitating condition.
