Within extremely precise limitations, the management of blood glucose levels in healthy individuals can be achieved and maintained. The glucose level rises immediately after a meal is consumed. Incretin hormones, which are appeared in the digestive system, play an essential function in the order of glucose, the maintenance of energy balance, and the protection of Langerhans islets cells. They are involved in the regulation of glucose levels in the body, and if their secretion is hindered, they can be used to anticipate the development of diabetes as soon as possible.The overarching goal of the research "is to identify the relationship between the production of GLP-1 and the development of insulin resistance", which ultimately results in type 2 diabetes.The case-control portion of current investigationdepends"on a revision of medical records from patients at the Clinic for Endocrinology", Diabetes, and Metabolic Diseases at the Clinical Center of Serbia, and computing the relevant parameters and doing statistical analysis.In terms of glucose profile, there was a substantial statistical divergence between the two groups that was found in the study. The relationship between Glucagon-like peptide 2 (GLP-2) and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) was found to be negative and statistically considerable (p=0.045). There was a statistically considerable positive association between DPP-IV and HOMA-IR (p=0.05).Our finding displays that insulin resistance can result in the suppression of glucagon-like peptide 1 production in persons with diabetes. According to the information presented here, reduction of GLP-1 secretion "is detached and will not occur in all people with poor glucose metabolism". This is due to a condition known as prediabetes, which will be discussed further in this section. Manuscript profile
