Diabetes is a most common lifestyle disorder in modern era affecting more than 11.8% of adult population in India and 9.3% in global world. It has been a major cause of morbidity with high mortality rate due to its side complications; viz. Cardiovascular disorders, Chronic renal failure, Hearing and sight disabilities, Impotency, Respiratory syndrome etc. Inspite of its mention in ancient Ayurvedic texts & various revolutionized medical scientific research, it is being considered a major concern to treat it without a disciplined life style schedule of daily regimen, viz. Physical exercise or frisk walking or games and sports etc.; Observation of indicated and contra indicated dietary protocol; relaxation with proper sleep or meditation etc. to counteract day to day stress and hazards. (Shembhekar and Kate, 1980; Sinha et al 2018; Sami et al 2017) The efficacy of Hathyogic practices has been well documented and recognized all over the world today in management of diabetes on the basis of scientific investigations in India and abroad since 4-5 decades along with WHO recommendations in 1980. Since the declarations of UNO for 21st June as International Yoga day in 2015, Yoga has been considered an effective tool for healthy living and management of lifestyle disorders.While analyzing the yogic protocol/intervention in the previous research studies, the criteria/logic for selecting a particular Hathyogic practices; vizAsnas, Pranayam, Mudra, Meditationetc. has been left unexplained and these practices are selected in randomized way without observation of principles of yogic therapy andtextual evidences of yoga and Ayurveda. Thus, the need of the hour is to define the yogic treatment for diabetes in context of Principles of Yogic therapy and textual evidences. This research paper deals with Yogic treatment of Diabetes on the basis of 35 years of therapeutic experience in yoga, textual evidences of Yoga and Ayurveda and in the light of defined Principles of Yogic therapy.
