Gastric electrical stimulation for gastroparesis improves nutritional parameters at short, intermediate, and long-term follow-up.

Background: Nutritional depletion, either macronutrient- or micronutrient-related, is common in patients with drug-refractory gastroparesis (GP) for which there is often no effective treatment. We studied a group of 12 patients (4 men, 8 women; mean age, 35.7 years) who had symptoms of GP and were a subset of the Gastric ElectroMechanical Stimulation trial of gastric electrical stimulation.
