Complications of Obesity in Polycystic Ovary Syndrome: Insulin Resistance and Inflammation.
Pak J Med Dentistry Jan ;10(2):16-21.

Background: The polycystic ovarian syndrome (PCOS), a well-known endocrine-metabolic disease, is caused by the interaction of environmental, genetic and metabolic factors. A cross-sectional, comparative study was planned to evaluate high sensitivity C-reactive protein (hs-CRP), insulin and lipid profile in non-obese and obese PCOS patients. Methods: Seventy-two women diagnosed with PCOS as per Rotterdam criteria, were placed in three groups in accordance with the body mass index: Group 1 (normal weight), Group 11 (overweight), and Group 111 (obese). Blood glucose, hs-CRP, serum insulin, lipid profile was estimated and insulin resistance was calculated. Data was analyzed using version 20 of SPSS. Analysis of variance (ANOVA) was used to compare the numeric variables among three groups of PCOS women and p-value < 0.05 was considered statistically significant. Results: Significantly, higher levels of insulin (13.03 ± 0.22), triglyceride (1.74 ± 0.96) and hs-CRP (7.24±4.11) were detected in obese PCOS women. The levels of fasting blood glucose (4.61±0.54) were also raised. Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) (2.69±0.79) showed insulin resistance in obese PCOS women (p=0.004). The obese group had significantly lower HDL-Cholesterol levels (0.82±0.09). Levels of total cholesterol (4.69±0.97) and LDL-Cholesterol (3.08±0.64) were increased but results were non-significant. These results indicate obesity leads to insulin resistance, dyslipidemia with low grade inflammation in PCOS. Conclusion: Frequency of insulin resistance, dyslipidemia and low-grade inflammation was found significantly higher in young obese PCOS women. Obesity may have an important role in the etiology as well as the complications associated with PCOS.
