The oral glucose tolerance test (OGTT) is a test widely used in clinical settings to analyze insulin release and insulin resistance in the body. However, because insulin sensitivity and insulin resistance are interdependent on each other, it is unclear to what extent insulin sensitivity and insulin resistance can be predicted (Stumovill et al 2000) . The oral glucose tolerance test (OGTT) is a measurement of how blood glucose is metabolized in the human body with the use of a sugar called "glucose" which serves as an important source of energy for the body (Hillson, 2002) . More importantly, fasting blood glucose and fasting insulin are the two main variables used in population-based assessment. There are two types of glucose tolerance tests: These tests are conducted and most often the diagnoses are compared to the standards set by the World Health Organization on diabetes. The oral glucose tolerance test is mainly used in pregnant women who suffer from gestational diabetes (diabetes mellitus), a hormonal change that occurs due to resistance of the placenta to insulin during the 24th to 28th week of pregnancy, pre- diabetes which can also be referred to as, a borderline diabetic which can be distinguished when a blood glucose level is higher than normal insulin resistance and hypoglycemia (Beckett et al, 2013). Likewise, this occurs in obese patients and in individuals with non-healing skin infections or in patients with a family history of infection. Along with that, there are factors that affect the blood glucose concentration in an individual, this factor includes: alcohol, smoking, food, medications, physical activity. activity, biological factors (stress, allergies) and environmental factors. Normally, the liver releases glucose to maintain blood sugar levels. However, if you consume an alcoholic drink, especially drinks enriched with carbohydrates, they would lead to an increase in blood sugar. Similarly, when alcohol is consumed on an empty stomach, glucose input into the bloodstream is reduced and, as a result, a drop in blood sugar levels occurs in hypoglycemia (ADA, 2015). The purpose of the experiment is to determine the blood glucose concentration via OGTT and the physiological mechanism by which the blood glucose level is controlled, using the OGTT in the diagnosis of diabetes
