Prediabetes is one of the major clinically entity and considered as grey area between normal one and diabetes mellitus. In my opinion, at this stage probably Vaman karma helpful in controlling blood sugar level and check its further progression to type-2 diabetes mellitus. Ayurveda strongly emphasize that when such clinical condition really established in the body for prolong duration, it may lead to Madhumeha vis a vis Diabetes mellitus. Due to, wide spread pathogenic involvement Vaman karma break the process of pathogenesis . If this is not happen in due time, the disease is deeply rooted and it is difficult to be cure. Based on the above hypothesis a study has been undertaken to evaluate the efficacy of certain Panchakarma measures (especially Vamana and Virechana) and avoidance of sugar cane products, newly rice & potato as remedial measures in a series of patients of Prediabetes. The present parallel study was conducted on 60 patients divided in three groups treated with Panchakarma (especially Vamana and Virechana measures) along with the diet group & control group treated with modern drug (Metformin). The observation will be made in terms of clinical symptomatology, BMI, FBS, PPBS, serum cholesterol and serum TG. This study reveals that patients on undergoing with Panchakarma therapy have good glycemic control and no unwanted effects were noted at the end of therapy.
