Yoga has been found to benefit all the components of health viz. physical, mental, social and spiritual well being by incorporating a wide variety of practices. Pathophysiology of Type II DM and co-morbidities in Type II DM has been correlated with stress mechanisms. Stress suppresses body's immune system and neuro-humoral actions thereby aff ecting normal psychological state. It would not be wrong to state that correlation of diabetes with stress, anxiety and other psychological factors are bidirectional and lead to diffi culty in understanding the interrelated mechanisms. Type II DM cannot be understood in isolation with psychological factors such as stress, anxiety and depression, neuro-endocrine and immunological factors. There is no review which tries to understand these mechanisms exclusively. The present literature review aims to understand interrelated Psycho-Neuro-Endocrine and Immunological mechanisms of action of Yoga in Type II Diabetes Mellitus. Published literature concerning mechanisms of action of Yoga in Type II DM emphasizing psycho-neuro-endocrine or immunological relations was retrieved from Pubmed using key words yoga, Type II diabetes mellitus, psychological, neural, endocrine, immune and mechanism of action. Those studies which explained the psycho-neuroendocrine and immune mechanisms of action of yoga were included and rest were excluded. Although primary aim of this study is to explain these mechanisms in Type II DM, some studies in non-diabetic population which had a similar pathway of stress mechanism was included because many insightful studies were available in that area. Search was conducted using terms yoga OR yogic AND diabetes OR diabetic IN title OR abstract for English articles. Of the 89 articles, we excluded non-English articles (22), editorials (20) and letters to editor (10). 37 studies were considered for this review. The postulated mechanism of action of yoga is through parasympathetic activation and the associated anti stress mechanism. It reduces perceived stress and HPA axis activation thereby improving overall metabolic and psychological profiles, increasing insulin sensitivity, and improving glucose tolerance and lipid metabolism. Yoga has positive effects on immune system of diabetics.– Overall, Type II DM is influenced by psycho-neuro-endocrine and immune mechanisms where Yoga has important positive role in combating stressors and improving these systems to regain health. |
