Abstract
PURPOSE OF REVIEW: To present and discuss recent and previous literature on the nutritional implications and management of gastroparesis. We also briefly review its epidemiology, pathophysiology, and clinical manifestations.
RECENT FINDINGS: - Low viscosity soluble fibers are well-tolerated in patients with mild to moderate gastroparesis symptoms and can thus be used to supplement the diets of these patients. - High-fat liquid meals are reasonably well-tolerated in patients with gastroparesis and can be used to supplement diet as tolerated. - The risk of tardive dyskinesia (TD) with long-term use of metoclopramide is much lower than previously thought. The nutritional status of patients with gastroparesis ranges across a wide spectrum, depending on the severity of their disease. Some patients improve simply with dietary modifications, others respond well to medical therapy, and those with severe, drug-refractory disease often require enteral nutrition or TPN (total parenteral nutrition). Generally, the recommended diet is composed of small particles, low fat, and low fiber; however recent studies showed that low viscosity soluble fibers and high-fat liquid fats can be tolerated. Metoclopramide is the first prokinetic agent of choice, and while the risk of TD is lower than previously thought, long-term use should be avoided in certain patient populations. For those on enteral nutrition, the choice of formula should be based on osmolarity, fat content, and fiber content, in accordance with the patient's tolerance.
