Thursday, May 13, 2021 (HealthDay News) – Weight loss surgery can cut the waist, and new research shows that it can also protect aging eyes.
The study found that the risk of cataracts after bariatric surgery (weight loss) can be significantly reduced, especially in young patients.
Why might that be? According to Swiss scientists, weight loss in obese patients can reduce oxidative stress in cells, inflammation of cells, and even diabetes, high blood pressure remission, all of which are healthy for the eyes.
In the United States, one surgeon called the findings “a real disaster” for weight loss.
Researchers have shown that “eating’s obesity-related effects affect almost every aspect of your health,” says Dr. Mitchell Roslin, director of obesity surgery at Lenox Hill Hospital in New York.
The study was led by Theresa Burkard, Dr. ETH of The Yurich. His team used data from national health registries in Sweden. The data were focused on more than 22,500 obese people who underwent obesity surgery between 2006 and 2019, and more than 35,500 obese patients who did not undergo bariatric surgery.
Patients ranged in age from 40 to 79, with an average of 6 years.
Although the study could not prove a causal link, the researchers found that the risk of cataracts in weight loss surgery was reduced by 29% compared with those who did not.
The lowest risk of cataracts was found in surgical patients aged 40-49 years, who were about 50% less likely to develop cataracts than those who did not have bariatric surgery, Burkard said.
In patients over 60 years of age, however, the beneficial effect seemed to disappear without a significant difference in cataract risk between groups.
The lowest risk of cataracts was associated with the surgical procedures that led to the greatest weight loss.
“Actions such as: [gastric] “Bypass or duodenal switch, which has more weight loss, less weight recovery, has a more pronounced effect on ‘cataract risk,'” Roslin said. This may be due to the fact that these procedures “change the diet more and provide more weight loss,” he said. sorted:
The Swiss team also saw no difference in reducing the risk of cataracts after bariatric surgery.
Dr. Matthew Gorsky is an ophthalmologist in Northwell Health in Great Neck, NY. Reading the findings, he said they give hope for a common, sometimes debilitating, eye disease.
“Cataracts are the leading cause of reversible blindness and vision loss in the world,” Gorsky said. Symptoms of cataracts include blurred vision, glare, headlights, loss of sensitivity to contrast, or difficulty perceiving depth. “Cataracts can lead to difficulty reading or driving during the day or night.”
Right now, “cataract surgery is the only way to treat cataracts – a low-risk, fast, effective procedure to improve vision,” Gorsky added.
“Obesity is a known risk factor for developing cataracts, so it makes sense that reducing obesity would reduce the risk of cataracts,” he said.
The results of the study were presented at a virtual meeting of the European Congress on Obstetrics on Wednesday. Findings presented at medical meetings should be considered preliminary until published in the peer-reviewed journal.
