Lasting weight loss with two small magnets. Nothing is cut away.
The magnets make a short cut inside your gut, so you feel full on less food and the weight stays off. It's done once, while you're asleep, and you're home the next day.
That's the whole device. Small enough to swallow with a glass of water.
You swallow one magnet that morning. Dr Loy places the other on the far side of the gut wall, and they click together, like magnets through a sheet of paper.
2
Over two to three weeks
Your body joins the two walls and opens a small doorway for food. The magnets then let go and leave naturally. You won't feel it.
3
From then on
Some food takes the short cut and reaches the part of your gut that says “I'm full” sooner. Smaller meals are enough, and you absorb fewer calories from what you eat.
1 / 3
Patients lose 34 to 39% of their total body weight in the first 12 months. Dr Loy will tell you what's realistic for you at your free assessment.

“…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.”
The difference
Why This Lasts When The Others Didn't
Diets
Your body fights back with hunger, and the weight creeps back.
Weight loss medication
Works while you take it. Stop, and the hunger returns, and the side effects and monthly cost add up.
Operations that remove or staple part of your stomach
They last, but recovery takes weeks, and what's removed can't be put back.
MagDI™
Done once, home the next day. Your own “I'm full” signal comes sooner, and nothing is removed.
Feeling nervous?
Worried About An Operation? That's Normal.
“It's a big operation and I'd be out for weeks.”
About an hour asleep, home the next morning, back at a desk in about a week.
“Something could go wrong.”
Every procedure carries some risk. Dr Loy explains yours honestly, and a full hospital team is around you.
“It's forever.”
It's reversible. Nothing is removed, so the new path can be closed again if it's ever needed.
“I have type 2 diabetes and high blood pressure.”
That's often why people come to us. Both often ease as the weight comes off.
“I'll be judged.”
Not here. You'll be listened to, not lectured.
Whatever is on your mind, ask it at your free assessment. That's what it's for.
Ireland's First Internationally Accredited Private Hospital
MagDI™ has been used in the US and Canada since 2021. The first procedures in Ireland and the UK were done here in September 2026, by Dr Loy, with Prof Michel Gagner, who developed it, at his side.
