New research suggests weight loss surgery may reverse the genetic signs of aging.
A small study found the chromosome caps called telomeres, which shorten as we age, actually grew longer in certain patients after bariatric surgery.
The growth was only two to three percent, but patients who were the sickest from obesity related illnesses seemed to benefit the most from the operation.
Patients who had high levels of 'bad' cholesterol and inflammation were also more likely to have telomere growth than those with lower levels.
Researchers say more studies are needed to confirm the effects of bariatric surgery on telomere lengths, and how it may affect a patient's actual health.
