175 people had weight-loss surgery in Irish hospitals last year to tackle obesity.
According to Freedom of Information files, almost three-quarters were women.
Bariatric surgery is an effective way to help and maintain weight loss.
It reduces your hunger and restricts the amount of food you're able to eat and absorb.
Some 46 men and 129 women - a total of 175 people - underwent obesity surgery in Irish hospitals last year.
That is up from 130 back in 2020.
Susie Birney is from the Irish Coalition for People Living with Obesity and had the procedure in the past.
She said: "I had type 2 diabetes and on the day of my surgery, my type 2 diabetes has been in remission - and that's since 2015.
"It's a life-changing, one method of treatment, for people who live with severe and complex obesity."
But she believes many more would have the procedure if it wasn't for long waiting lists.
"It's years, it's not months... in the public system, people have to wait years.
"They actually see their multi-disciplinary team first, and they go through that process.
"And then if they meet the criteria, they go on the list for metabolic surgery or bariatric surgery.
"And that can be a matter of years, unfortunately".
61 people aged between 30 and 44 had obesity surgery last year.
