I believe that many people have had the question, that is, why some diabetic patients are as thin as wood, while some are very obese? We first understand the pathogenesis of diabetes, most of the blood sugar is elevated because the function of the pancreatic islet cells decline, the secretion of insulin is not enough to meet the body’s needs to break down sugar resulting in the inability to use from the points, blood sugar will be lost and wasted, the body will provide calories through the breakdown of fat, so it is getting thinner. But why are many diabetic patients in life is the body overweight or obese it? Some are still general belly! This is because insulin is not only the role of blood sugar control, many physiological activities in the body are directed by insulin, especially the metabolic process of fat, insulin is no substitute. Simply speaking, in general, if blood sugar is relatively high, insulin will convert the excess blood sugar into fat, in addition to promoting the cells to consume blood sugar. And through these conversion processes, fat will be stored, mainly in our liver and intestines. Therefore, when the body’s insulin is insufficient, this process will not be completed, so there will be some patients who are getting thinner and thinner. On the other hand, for obese patients, especially before the onset of diabetes, or even within the years of getting the disease, there is a special phenomenon, that is, the insulin in the body is not lacking or the degree of reduction, or even higher than normal levels, but the sensitivity of the cells to insulin is reduced, and it simply does not play the role of breaking down blood sugar, we call this phenomenon insulin resistance. In the future, for the treatment of diabetes, it is also necessary to develop treatment plans according to different physical conditions of different patients, diet, exercise, education, psychology, especially for obese patients with metabolic corrective surgery treatment, etc. This is a comprehensive sugar control program, tailored to the individual, so that more people can have a healthy body.
