Correlation between Increased BMI, Metabolic Syndrome, and Benign Prostatic Hyperplasia in Young Obese Males: A Comprehensive Review

Abstract

Background: Benign prostatic hyperplasia is a prevalent condition affecting men, with risk factors such as age, lifestyle, inflammation, sex hormones, and genetics. However, the link between metabolic syndrome and BPH has gained attention, particularly among young, obese males under 40. Literature Review:  This review explores the incidence and impact of increased body mass index and metabolic syndrome in causing benign prostatic hyperplasia (BPH) in young, obese males, particularly those under 40 years old. The connection between BPH and MetS was first noted over twenty years ago by Hammarsten and colleagues, who found a direct correlation between Mets components and prostate volume. Subsequent studies in the United States and the United Kingdom corroborated these findings, showing that young males with three or more MetS components have a higher risk of developing BPH. Studies employing the American Urological Association Symptom Index indicated that men with mild lower urinary tract symptoms (LUTS) significantly increased MetS prevalence among men under 40 years old. Research in Asia has highlighted a growing incidence of LUTS, correlating with increased blood pressure, fasting blood glucose, and increased BMI.  A meta-analysis found a 28% higher chance of developing BPH among men with higher BMI, and Obese persons were found to have a chance of having an enlarged prostate that was three and a half times higher than the average. Besides BMI, Various studies have examined other clinical markers associated with obesity, such as dyslipidemia and elevated serum insulin levels, which have been linked to increased prostate growth rates. Conclusion: These findings underscore the need for further research to understand the mechanisms and address the disparities in BPH prevalence among different racial and ethnic groups. Addressing obesity and MetS through lifestyle modifications and medical interventions could potentially reduce BPH incidence in young, obese males.
