What is in it for you

What A Gastric Bypass Can Do For You

  • Significant, lasting weight loss

    On average, people lose 60 to 70% of their excess weight, and most keep at least half of it off ten years later.

  • Less hunger

    A bypass changes the hormones that drive appetite, so you want less and feel full on smaller portions.

  • Fewer cravings

    Many people find they lose interest in sugary and high-fat foods.

  • Help with type 2 diabetes

    A gastric bypass improves type 2 diabetes for many people.

  • Easier on your body

    Losing weight reduces back and joint pain and lowers the risk of heart attack and fatty liver disease.

  • Proven over decades

    The gastric bypass is one of the most studied weight loss operations there is.

Results vary from person to person. Dr Loy will give you a realistic picture for your circumstances.

Another Option Dr Loy May Discuss With You

For some people, Dr Loy may also talk about MagDI™. It gives the effect of a bypass, but the new connection in the gut is made by two small magnets, which then pass naturally within two to three weeks. It has been in clinical use since 2021 and, in Ireland, it is available only at Auralia.

You do not need to choose. Dr Loy will recommend what suits you.

What Patients Say About Meeting Dr Loy

“Meeting Dr Loy to discuss the best surgery for me, I felt it was the first time in my life I was genuinely being listened to and not just blamed or judged for being overweight.”

Sarah K., Trustpilot review, April 2026

“He took the time to explain everything clearly and made sure I felt comfortable every step of the way.”

Miroslav P., Trustpilot review, November 2025

“The team hand hold you throughout, follow up calls, check ins, and 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 afterwards.”
