Weight loss surgery may reverse liver damage

Bariatric surgery (weight loss surgery) can reverse liver damage in obese people, a new study has discovered.

The study added that this surgery is also good for the obese patients of the nonalcoholic fatty liver disease (NAFLD).

"Doctors should consider bariatric surgery as the treatment of choice for NAFLD in severely obese patients," said Michel Murr, a professor of surgery at University of South Florida-Tampa.

Murr said that patients with a body mass index greater than 35 and obesity-related co-morbidities, or a body mass index of greater than 40, can undergothis surgery to prevent liver related damagers.

For the study, liver biopsies from 152 patients - one at the time of the bariatric procedure and a second an average of 29 months afterwards - were compared by the researchers.

The researchers then reviewed post-operative biopsies and found that bariatric surgery resulted in improvements for these patients.

"As a tool in fighting obesity, bariatric surgery could also help prevent the emergence of widespread liver disease," he added. The findings of the study were published in the journal Digestive Disease Week (DDW).

Bariatric surgery is also known as weight loss surgery and it is used by obese patient to reduce their body weight.
