The unexpected effects of Wegovy
Wegovy (semaglutide) is attracting a lot of attention for its powerful weight loss effects.
But have you ever heard the saying, “A weight-loss drug can also reduce drinking”?
As I was looking through the literature myself, I found a study showing that Wegovy also has a meaningful improvement effect on Alcohol Use Disorder.

It is not just about reducing body weight.
It may also affect the brain’s reward system and addictive behaviors.
Today, I’ll organize Wegovy’s unexpected effects based on scientific evidence and clinical experience.
📌 Wegovy’s “anti-addiction effect” revealed in a study of 80,000 people
According to a large-scale data analysis conducted in the United States,
83,000 patients with obesity
600,000 patients with diabetes

Based on their charts,
researchers tracked alcohol-related changes in Wegovy users.
As a result,
✔ 50% reduction in the risk of developing alcohol use disorder
✔ 56% reduction in relapse rates among patients with existing alcohol use disorder
In other words,
this is a meaningful result suggesting that Wegovy may also have a therapeutic effect on alcohol use disorder.
📌 Why does Wegovy reduce addictive behavior?
(GLP-1 & dopamine)
Wegovy is a GLP-1 receptor agonist (GLP-1 RA).
GLP-1 receptors exist not only throughout the body, but also in the brain.
Addiction ultimately begins in the dopamine reward circuit.

Human brain
Dopamine must be released in order for us to feel pleasure from food, alcohol, gambling, shopping, and so on.
When that pleasure is repeated, addiction forms.
But Wegovy acts on two things at the same time.
First, it reduces dopamine release itself,
and second, it also blunts responsiveness to dopamine.
As a result, obsession with and craving for reward behaviors such as food, alcohol, smoking, shopping, and gambling decreases.

In other words,
Wegovy can be seen not just as a simple diet drug, but as a neuroendocrine medication that acts on the brain’s reward system.
📌 Changes confirmed in real-life use by staff members
When my staff and I used Wegovy together, we shared a common observation.
“I suddenly stopped my habit of drinking alone every night.”
“Alcohol doesn’t taste the same as before, and it isn’t enjoyable.”
“Even when I try to drink, I can’t drink as much as I thought.”

At the beginning of Wegovy treatment,
people may try to drink out of habit,
but a decrease in interest in alcohol is very common over time.
In addition,
for some patients,
✔ reduced mood swings
✔ relief from feelings of depression
have also been reported as mood-improving effects.
(Of course, this is not an official efficacy claim, but an observed phenomenon.)
📌 A “virtuous cycle” of health, mental health, addiction, and dieting
If we organize the positive changes that may appear while using Wegovy, they are as follows.
Weight loss
Improvement in blood pressure, blood sugar, and triglycerides
Reduced drinking and smoking
Better physical health
Improved condition and mood
Feeling better, so dieting works better too

In this way,
a flow may emerge in which physical health → mental health → addiction behavior management → weight management
influence one another and create a virtuous cycle.
📌 It is not an officially approved indication
Wegovy’s anti-addiction effect is not an official indication.
Wegovy is currently approved as a treatment for obesity,
but it is not approved as a treatment for alcohol use disorder.
Therefore,
this effect should be understood as a possible additional benefit.
📌 Next-generation weight-loss drugs: beyond Wegovy
After Wegovy,
even more powerful next-generation drugs are appearing.

- Cagrilintide + Semaglutide
Wegovy ingredient + amylin analog
Reports of stronger weight-loss effects than GLP-1 drugs
- Retatrutide
Triple action of GIP + GLP-1 + glucagon
Weight loss rate of over 25%, with effects comparable to partial gastric and intestinal resection surgery
- Orforglipron
An oral (taken by mouth) GLP-1 drug instead of an injection
Greatly improved convenience of use
In the future,
options for obesity treatment are expected to become much more diverse.
📌 Closing remarks
Today, I organized Wegovy’s “unexpected effects,”
that is,
its reduction of addictive behavior and regulation of the brain reward system,
based on scientific evidence and clinical experience.
✔ Lose weight
✔ Become healthier
✔ Reduce addictive behavior
✔ Improve mental health

Wegovy may be a medication that contributes not only to simple dieting,
but also to overall health recovery.
Of course,
every effect varies greatly from person to person,
and it is only safe to take it after consulting a specialist.
As more research results become available in the future,
I will organize additional information again.
Thank you for reading.
