GI Detox

How GI detox works

Clearing and rebalancing your gut builds the foundation for weight loss.

Gut bacteria testing
01

Gut bacteria testing

We check the balance of harmful and beneficial bacteria. Knowing your gut is the starting point.

Witch Slim Laser

Nonsurgical fat reduction,
developed at WEBIEN

Witch Slim pairs Witch Potion,
a fat-dissolving solution formulated by Dr. Hong-chan Lee,
with HIFU Plus high-intensity focused ultrasound.

The solution breaks down fat cells in the treated area,
and HIFU Plus helps your body clear the fat and waste.

Gastric balloon × Witch Slim

A gastric balloon helps you eat less, but it doesn’t shrink the fat cells themselves, a common cause of weight regain.
Adding a fat-dissolving treatment to reduce the fat layer makes the results more effective.

Medication

Two types of weight-loss medication

Medications come as injections or pills. They work differently, so the right choice depends on your body.

Injectable weight-loss medication pens
Injectable

Injectable medication

These medications slow how quickly food leaves your stomach and act on appetite signals in the brain,
so you feel full longer on less food.

Dosing
Daily or weekly injection under the skin
Best for
Appetite that’s hard to control
Oral weight-loss medication tablets and capsules
Oral

Oral medication

Options include medications that curb appetite and cravings or reduce fat absorption.

Dosing
Taken daily by mouth
Best for
Patients who prefer to avoid injections

Whatever the medication, results last longer
with healthy eating and activity habits.

More important than the type

It’s not about which drug —
it’s about the right one for you

The same medication can work well for one person and not for another.
The right choice depends on your weight, related conditions, lifestyle and diet history.
Our surgeon evaluates you before prescribing and follows your progress
until you finish treatment.

Medication is a tool.
Care and guidance set the direction.

Gastric Balloon

An MFDS-approved
BIB gastric balloon

We use the BIB gastric balloon approved by Korea’s Ministry of Food and Drug Safety (MFDS). An endoscopy beforehand confirms whether the balloon is right for you.

After placement, you get six months of one-on-one follow-up with your physician and a personalized plan.
Additional procedures are available if needed.

Probiotic Gastric Balloon

Weight loss and gut health,
treated together

The probiotic gastric balloon combines two procedures. The BIB gastric balloon helps you feel full sooner and reset your eating habits, while endobiotics deliver probiotics directly into the small intestine by endoscopy.

An unhealthy gut can slow weight loss. Treating both helps you manage your weight and your gut at the same time.

Before treatment, gut bacteria testing checks your current gut health,
and we guide your diet and probiotic plan based on the results.

Sleeve Gastrectomy

Reducing the stomach
to about one-third

We remove the outer curve of the stomach, including the fundus — the part that stretches most — leaving a narrow sleeve that doesn’t expand easily.

As a result, you feel full on much smaller portions,
so you naturally eat less and lose weight.

Laparoscopic Surgery

One-day, single-port laparoscopic surgery

Same-day
surgery

Surgery follows consultation and testing to confirm your condition.

Same-day
discharge

You can get back to daily life quickly, depending on your condition.

Single-port
technique

One small incision at the navel keeps scarring to a minimum.

* Some procedures or conditions may require a hospital stay.

Before & After

Individual results may vary, and side effects are possible depending on the treatment. Please talk with our medical team for details.

We don’t stop at the number on the scale.
We rebuild your health from the foundation up.
