 The research plan involves reviewing patient records to identify potential subjects. Questionnaires will be distributed to gastroparesis patients and their caregivers during their visit to the GI clinic at the day of enrollment and at six-month intervals for a two-year follow-up period, after informed consent has been obtained. Patients and caregivers will also be recruited by telephone. Gastroparesis patients, who have an established patient-physician relationship with Dr. Sultan, will be contacted by telephone in order to inquire about their interest in participating in the study. The details of the study, including the questionnaires, risks, and potential benefits will be discussed over the phone. Then, if patients andor their caregivers are willing to participate in the study, the informed consent forms and the questionnaires will be mailed to them with a posted envelope to be returned to Dr. Sultan by mail.
