Abstract
The disclosure is directed to techniques for delivering electrical stimulation therapy to support obesity management. The electrical stimulation therapy is configured to cause at least partial gastric distention. Gastric distention tends to induce a sensation of fullness and thereby discourages excessive food intake by the patient. The electrical stimulation therapy may be delivered to the gastrointestinal tract of the patient by electrodes deployed by one or more implantable leads coupled to an electrical stimulator. The electrical stimulator delivers stimulation pulses having a pulse width in a range found to be effective in causing gastric distention.
