The present study was undertaken to find the role of dietary intervention and physical exercise on serum bilirubin level in IGT subjects. Thirty three newly detected otherwise healthy subjects with IGT, aged 35-63 years, were randomly selected to participate in a 12 weeks diet and exercise program. Nine participants were within 35-40 years while majority fifteen participants aged 41-50 years and rest six participants were above 50 (51-63) years. A male preponderance was observed among the study participants where 53.3% of the total participants were male (n=16) and 46.7% were female (n=14). Mean bilirubin (mg/dl) level was recorded 0.68 ± 0.29 at base line and with follow-up, the value was 0.66 ± 0.26 mg/dl. For men (n=16), serum bilirubin were 0.77 ± 0.39 and 0.75 ± 0.36 mg/dl at base line and follow-up while for women (n=14), the values were 0.67 ± 0.33 and 0.59 ± 0.28 mg respectively. The 35-40 years group (n=9) showed bilirubin from 0.66 ± 0.23 at base line to 0.73 ± 0.19 mg/dl at follow-up while 41-50 years group (n=15) had 0.70 ± 0.34 and 0.58 ± 0.26 mg/dl and for 51-63 years group (n=6), the values were 0.65 ± 0.29 and 0.73 ± 0.33 mg/dl respectively. Participants with BMI 20-25 had bilirubin 0.62 ± 0.29 mg/dl at base line and 0.71 ± 0.21 mg/dl at follow-up while with BMI >25 (n=20) had 0.71 ± 0.30 and 0.63 ± 0.2 8 mg/dl respectively. No significant changes in serum bilirubin were observed among the groups and therefore, the dietary intervention and physical exercise during the period did not have a significant role in this respect.
