Glucose Tolerance Curve… Measuring cell sensitivity
Bad eating habits and the physical inactivity that characterizes our current lifestyle, are primarily responsible for the high excess weight, obesity, metabolic syndrome and Type 2 Diabetes incidence that is currently affecting the world’s population.
Excess weight and obesity lead to several health problems, but one of the main harmful effects these cause on the body, is that they can make our cells lose their sensitivity to insulin signals, which help metabolize the food (glucose) we eat, that is, the cells become insulin resistant and our blood glucose levels tend to increase.
Remember that excess weight and obesity, with a highly increasing incidence, are primarily responsible for the Type 2 Diabetes epidemic. Excess fat cells (adipocytes) in the adipose tissue, especially around the waist, tend to lead to insulin resistance among other serious health problems. Insulin resistance is a condition that indicates a certain degree of cell sensitivity loss to insulin signals, preventing glucose from entering the cells so it cannot be used as fuel. This in turn causes blood glucose (glycemia) levels to rise as the cells become more insulin resistant or glucose intolerant. If we don’t take timely measures, this situation will worsen and glucose levels will reach values deemed as Type 2 Diabetes.
The glucose tolerance curve is a very important test that allows us to know the degree of insulin resistance our cells have, i.e., how sensitive our cells are to insulin signals, which advices us on the action we should take, so our cells can again become increasingly sensitive to insulin signals and so we can prevent or delay a Type 2 Diabetes diagnosis.
