Gastric electrical stimulation
Gastric Electrical Stimulation
Gastric electrical stimulation (GAS-trik eh-LEK-tri-kal stim-yoo-LAY-shun) is a medical procedure used to treat chronic gastrointestinal disorders.
Etymology
The term originates from the Latin gaster meaning stomach, and the English electrical stimulation referring to the application of electrical current to stimulate a response.
Definition
Gastric electrical stimulation involves the use of a device that sends mild electrical pulses to the nerves and smooth muscle of the lower stomach. This is thought to help control nausea and vomiting in people who have severe gastroparesis.
Procedure
The device used in gastric electrical stimulation, often referred to as a gastric pacemaker, is surgically implanted under the skin in the lower part of the body. Wires from the device are connected to the stomach. The device can be adjusted to send different amounts of electrical stimulation to the stomach.
