All patients who initiated treatment with Lorcaserin during the review period will undergo chart review. The primary endpoint will be weight change in patients on Lorcaserin and average duration of Lorcaserin treatment over time (up to 1 year). Secondary endpoints will include changes in vital signs, liver function, glucose, and lipids. In addition, time on treatment, reasons for discontinuation of medication, and changes in healthcare utilization (to include inpatient and outpatient utilization) will be examined. This is a retrospective, one-arm observational study that will include chart reviews of 157 patients who have been treated in the clinic.
