SMALL MAGNETS. REAL CHANGE.

How does it
help me lose weight?

A shortcut lets some food reach the lower gut sooner. This helps change hunger signals and reduces the calories your body absorbs.

INSIDE YOUR BODYTwo parts of the gut held together by the MagDI magnetsIllustration: GT Metabolic
01 / 03

Your body makes the connection.

Two magnets hold two parts of your gut together. A new opening forms without cutting or staples at the join.

MagDI is keyhole surgery under general anaesthetic. It can be done alone, with a sleeve, or after earlier weight-loss surgery.

WHY MAGDI WORKS DIFFERENTLY

You've tried hard.
MagDI works differently.

01

DIETING ALONE

Less reliance
on willpower.

MagDI changes hunger signals. Eating less doesn't have to depend on fighting your appetite alone.

02

ONGOING INJECTIONS

A procedure.
No repeat dose.

An option to explore if you want a lasting physical change instead of ongoing weight-loss medication.

Minimally invasive, meaning that there’s less pain, faster recovery.Professor Michel Gagner · MagDI pioneer

“Do the magnets stay inside me?”

No. They pass naturally after the connection forms. No permanent magnets.

“Can it be reversed?”

The new connection can be closed with another operation. A sleeve, if included, cannot be reversed.

“What if I'm not suitable?”

That's what the free assessment is for. Dr Loy will explain your options.

HEARD. UNDERSTOOD. LOOKED AFTER.

“For the first time,
I felt listened to.”

“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.”

“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.”
