Effect of yoga on pulmonary function tests of hypothyroid patients.

Aim of this study was to see any effect on respiratory functions in hypothyroid patients after pranayama (yoga). The subjects for the study were 20 hypothyroid females, 39.70 +/- 8.27 years of mean age referred from medicine department of UCMS & G.T.B. Hospital. Spiro metric recordings were taken with hypair (version-1.28). Baseline (first) recordings were taken when patient came for the first time. Patients came to yoga lab in physiology department for 21 days continuously where they were trained by the yoga instructors and then told to do pranayama at home and called at regular intervals after 7 days to see the compliance. The breathing exercises were done for 45 minutes everyday. After 6 months of pranayama second recording was taken and compared with the baseline. There were significant improvement in forced expiratory volume in first second (FEV1), Maximum voluntary ventilation (MVV) and Inspiratory Capacity(IC). Thus Pranayama and meditation has beneficial effect on pulmonary functions of hypothyroid patients along with conventional treatment.
