Quick answer

WegoSlim: what to know first

WegoSlim is Hori Clinic's physician-supervised semaglutide weight-management programme. It is considered only after confirming eligibility, the exact medicine and labelled risks, and it works alongside nutrition, physical activity and follow-up rather than replacing them.

Suitable for: Adults with obesity, or overweight with a related health condition, after medical eligibility assessment
Discuss first: Discuss pregnancy plans, personal or family thyroid-cancer history, MEN2, severe gastrointestinal disease, pancreatitis or gallbladder history, kidney risk and all medicines
Discomfort: A brief injection prick; nausea, fullness, constipation or diarrhoea may be more relevant than injection pain
Downtime: No procedural downtime, but gastrointestinal symptoms and dehydration can affect daily activity
When change may be noticed: Appetite effects may begin after starting treatment; weight change is gradual and assessed over months
Alternatives: Nutrition, physical activity, behavioural care, another approved medicine or bariatric referral

What is WegoSlim?

WegoSlim is a doctor-supervised weight-management programme based on semaglutide, a once-weekly GLP-1 receptor agonist. It mimics GLP-1, a natural gut hormone released after eating that signals fullness to the brain and helps regulate blood sugar.

By making you feel full sooner and for longer and reducing cravings, it makes a calorie-controlled diet easier to sustain. It is started low and titrated up under medical supervision, alongside nutrition and lifestyle coaching — not a replacement for them. A doctor screens suitability and monitors progress and side effects.

How it works

Semaglutide activates GLP-1 receptors that regulate appetite.

You feel full sooner and for longer, reducing overall intake.

Combined with diet and lifestyle coaching under a doctor’s care.

Why it may help

Why WegoSlim

✦Helps you feel full sooner and longer
✦Once-weekly, doctor-supervised
✦Supports gradual, sustainable weight loss
✦Well-studied GLP-1 mechanism

A doctor may consider it for

—Difficulty controlling appetite or portions
—Weight loss has stalled with diet alone
—Want medically supervised support
—Ready to pair it with lifestyle change

On the day and afterwards

After a medical assessment, semaglutide is given as a once-weekly injection, typically started low and titrated up under supervision. The clinic guides injection technique, nutrition and side-effect management.

Mild nausea or digestive changes may occur early and usually settle as the dose is titrated. Regular follow-up monitors your progress and safety throughout.

When changes may appear

Weight loss is gradual over weeks to months and is most effective with diet and lifestyle support. As a medical programme, results and suitability are determined by your doctor.

Everyone responds differently. Before treatment, your doctor will examine the area and talk through a plan that makes sense for you.

WegoSlim, answered.

How is WegoSlim different from Mounjaslim?+

WegoSlim is based on semaglutide (GLP-1), while Mounjaslim is based on tirzepatide (GLP-1 + GIP). Your doctor advises which suits you.

Is it safe?+

It must be prescribed and supervised by a doctor, who screens suitability and monitors you. It is not appropriate for everyone.

Do I still need to diet?+

Yes — the medication supports appetite control, but lasting results come from combining it with healthy eating and activity.
