Therapy to Obese Type 2 Diabetes Mellitus:How Far Will We Go Down the Wrong Road?

Traditional glucose-lowering chemical agents, including various types of insulin and insulin secretagogues, insulin sensitizers, gliptins, etc., are based on diabetic pathogenesis of insulin resistance(IR) and islet insufficiency. Numerous evidence-based medical studies have shown that these traditional hypoglycemic chemical agents do not provide cardiovascular benefit to patients with type 2 diabetes mellitus(T2 DM) and may even increase the risk of all-cause mortality. Based on research evidence published to date, these studies show that overload of energy could increase the incidence and prevalence of T2 DM, and reduction in the heat load can significantly reduce the incidence of T2 DM. Therefore, the essence of T2 DM is heat overload, meaning heat overload is the etiology of obese T2 DM. At the same time, results of numerous studies show that heat overloading is the cause of IR. IR and islet dysfunction are protective factors in intervening with heat overload.These drugs, which are based on the mechanisms of IR and islet insufficiency, increase caloric reserve and cause or worsen obesity, which is equivalent to exacerbating the basic etiology and the cardiovascular risk factor of T2 DM. Thus, a reasonable strategy for prevention and treatment of obese T2 DM appears to promote the negative balance of calories and the elimination of caloric reserves. Chinese herbal medicines can promote negative balance of heat in many aspects, which can bring new hope for prevention and treatment of T2 DM.
