[Cheongdam OK Clinic] Wegovy Clinical Results and Real-World Cases

Wegovy,

Does it really work?

In the previous post,

we looked at the principles and effects of Wegovy.

�

This time,

we’ll focus on practical information such as

real-world cases, side effects, and precautions.

The clinical trial results for Wegovy published in the world’s most authoritative medical journal (NEJM),

and

real experience cases from medical staff and hospital employees

show Wegovy’s

‘true effects’ in vivid detail.

Wegovy’s effects: have they been proven in clinical trials?

To answer first,

Yes! They have been clearly proven.

Wegovy is a treatment that demonstrated both safety and effectiveness through the STEP series of clinical trials.

📊 STEP 1 Clinical Trial Summary (NEJM, 2021)

• Number of participants: 1,961 (BMI ≥ 30)

• Treatment period: 68 weeks (about 1 year and 4 months)

• Main results:

• Average weight loss rate: 14.9%

• More than 50% of participants lost 15% or more

👇 Below are the clinical trial results comparing Wegovy (semaglutide) and the placebo group.

STEP 1 Clinical Trial Results

Placebo group: the comparison group that received a “fake drug” without any actual drug ingredients.

These numbers show

not just a simple diet pill,

but a change at the level of being able to treat obesity.

What about in Korea? Obesity rates are low, but demand is high

Korea is a country with a low proportion of people with severe obesity,

with BMI 30 or higher.

According to Ministry of Health and Welfare data,

only about 5.9% of adults

are classified as having a BMI of 30 or higher.

In the OECD obesity rate ranking by country,

Korea ranks 31st out of 32 countries.

(Japan is 32nd)

Comparison of obesity population ratios by country (OECD 기준)

But

the interest in dieting is very high.

Real-life Wegovy use cases: a real story from our clinic’s medical staff

In January 2025,

at Cheongdam OK Clinic,

two directors and two staff members decided to lose weight

and began Wegovy treatment.

Director S

Comorbidities: high blood pressure, hyperlipidemia, prediabetes

• Results -

Lost about 16 kg (19%)

Both blood pressure and blood sugar levels normalized

Improved blood lipid levels

Overall health improved

Lucky draw Dr. and staff members

BMI: under 27

Although they did not exceed the approval criteria, they were prescribed at the doctor’s discretion

Noticeable changes such as reduced appetite, less snacking, and body shape changes

Lucky draw Dr.: lost 14 kg

Director P: lost 6.9 kg

Team Leader M: lost 10.7 kg

Everyone succeeded in their weight loss goals

and are maintaining them well.

Looking at the cases above,

we can confirm that even with a BMI under 27, it can be used safely

for medical purposes and under supervision.

📌 Even if BMI is under 27,

it may be prescribed at the doctor’s discretion

by comprehensively considering health status, lifestyle habits, and past dieting failures.

Wegovy changed more than just weight

"weight-loss drug,"

but what’s even more important is

the changes in health indicators .

• Metabolic benefits of Wegovy -

Blood pressure stabilization

In other words,

it’s not just about losing weight,

but about expecting improvements in the body’s overall health as well.

What you must know before using it

Because Wegovy is a prescription medicine,

we recommend using it only after consulting with a doctor.

Underlying conditions need to be checked

Health conditions such as diabetes and gastrointestinal disorders

should be assessed in advance,

Ongoing follow-up management is essential

It is important to monitor for changes while taking the medication.
