Patients who underwent laparoscopic sleeve gastrectomy in the 6 month period between 01/04/2012 and 01/10/2019 were identified. For those meeting the inclusion criteria, demographic and medical data was extracted from hospital notes. This included initial BMI and the presence of, or treatment for, diabetes or hypertension.
Using the contact details available in the medical records, a scripted telephone interview was performed. The current weight of the patient as well as a current medical and drug history were elicited. This data was compared with data attained during initial patient interaction with the service.
Early weight loss, defined as weight lost in the 4 weeks following surgery, was subsequently correlated with outcomes in terms of weight loss and improvement/resolution of either hypertension or diabetes at a 7 year follow up interval.
