Change in insulin resistance, beta cell function, glucagon-like peptide-1 and calcitonin levels two weeks after bariatric surgery

Bariatric surgery causes profound improvement in metabolic parameters by increasing plasma glucagon like peptide - 1 (GLP-1) level even few weeks after surgery. GLP-1 analogues can cause calcitonin secreting medullary thyroid carcinoma in animals. The studies relating to the mechanisms that underlie these changes are few. The objectives of the study were to measure the change in insulin resistance, beta cell function, GLP-1 and calcitonin levels...
