"Anti-aging" hormone could actually shorten life
Common anti-aging treatments involving hormone-replacement therapy may actually decrease a person’s life span, according to a study at Albert Einstein College of Medicine in New York.
Researchers conducted an 11-year study of 184 men and women in their mid 90s. The researchers found that the people who had the greatest chance of living through the study period had relatively low blood levels of hormone called insulin-like growth factor 1, or IGF-1. The findings add to those of previous studies that have found individuals with high IGF-1 levels have an increased risk of cancer death.
The results of the study, published in the journal Aging Cell, are significant because it reflects the potential dangers of the anti-aging treatment that involves administering human growth hormone (HGH). It causes the body to produce higher levels of the hormone IGF-1.
The study did not explain what the findings might mean for treatments now offered by anti-aging clinics. Researchers explained that while their study provides better understanding of side effects of anti-aging hormone therapy, further research is necessary to better understand the complex relationship between hormone levels, life expectancy and disease.
