The big worry

Put Off By The Thought Of A Big Operation?

You're not alone. It's the main reason people never go ahead. MagDI™ was designed to be different.

  • “I don't want part of my stomach cut away.”

    Nothing is removed. Two small magnets make a new path for your food, instead of staples.

  • “What if something goes wrong?”

    In the published studies, the magnets connected in every patient, with no leaks at the join.

  • “I can't put my life on hold.”

    Most people are back at a desk job within one to two weeks.

  • “What if I change my mind?”

    Your gut is kept whole, so the new path can be closed again if it's ever needed.

What changes for you

Not Another Diet. A Lasting Change.

Food normally takes a long route through the gut. MagDI makes a new shortcut, and part of your food takes it. Food Stomach Usual route New shortcut
Usual routeNew shortcut
  • Satisfied with smaller meals

    The shortcut makes your body produce more of its own fullness hormone, so you stop fighting your appetite.

  • Weight that stays off

    Because the change in your hunger is long term, keeping the weight off doesn't come down to willpower.

  • Healthier blood sugar

    In the first study, people with type 2 diabetes saw their average blood sugar fall from 8.2% to 6.6% within a year.

More energy, clothes you love, keeping up with the kids, and feeling like yourself again.

Results vary from person to person.
