“Through my bypass I lost and maintained a 14st loss. Recovery was smooth sailing and my team was frequently in touch to see how I was.”
“After many years of procrastination I finally contacted Auralia seeking information regarding bariatric surgery, I was a nervous wreck and had no idea what to expect. From the very first consultation Dr. Loy put me completely at ease… he listened and there was no hard sell, no shaming, no judging.”
You've tried diets, apps, slimming clubs, maybe weight loss medication. Here's what a bypass changes.
“The weight always comes back.”
A bypass changes how much you can eat for the long term, so the weight doesn't creep back the way it does after a diet. Ten years on, most people still keep at least half of their extra weight off.
Most people lose about 70 to 80% of their extra weight.
“My knees and back ache.”
With less weight to carry, back and joint pain often ease, so stairs and walks get easier.
“I have type 2 diabetes or high blood pressure.”
Both often ease as the weight comes off.
“I hide at the back of photos.”
Stand in the middle of the family photo, not hidden at the back.
Your surgeon makes a small pouch at the top of your stomach, about the size of an egg. That's why a small meal is enough.
The pouch is joined further down your gut, so food skips the first part of it. That's why type 2 diabetes often improves so quickly after a bypass.
You spend one night in hospital and recover in about two weeks.


It's keyhole surgery, about 1 to 2 hours, and Dr John Loy, who leads our bariatric unit, has done almost 3,000 weight loss operations. You can ask him anything before you decide.
Call the surgical team's 24/7 number, any time, day or night.
Not here. You'll be listened to, not lectured.
Sugary food can make you feel faint or sick soon after eating. It's called dumping syndrome. Your dietitian shows you which foods to avoid.
Yes. You take vitamins and minerals every day and have regular blood tests. We guide you on both.
That's what your free assessment is for.

Lasting results come from the support after your operation, and it's all included.
A dietitian programme, so you know what to eat at every stage.
The Auralia app, with exercise, lifestyle and cooking classes, a food diary and messages to your dietitian.
Follow-up appointments, planned for you.
“…as Dr Loy said on the day of leaving after the Op, our care continues for months following the Op, which was comforting when you are at home alone afterwards.”
Your hospital is in Dublin, with clinics in Kilkenny and Limerick. Unlike a package abroad, if anything needs checking after your operation, your own team sees you here.
