The disclosure describes techniques for electrical stimulation to regulate
the caloric intake of a patient and thereby alleviate obesity. A first
set of stimulation pulses is delivered to the stomach to suppress
appetite and limit food intake, and a second set of stimulation pulses is
delivered to the small intestine to accelerate food transit and reduce
caloric absorption. In this manner, the electrical stimulation limits
food intake and caloric absorption, providing a two-pronged therapy for
obesity. In a sense, the electrical stimulation electrically mimics the
physiological effects of the Roux-en-Y gastric bypass procedure without
the need for surgery.
