Frequently asked questions

How quickly can I have this procedure?

We offer regular clinics and a date for the procedure will be discussed within the appointment. There are no waiting lists for this procedure. You should be able to have it done within a couple of weeks of enquiring if it’s determined you’re eligible and you’d like to go ahead.

How long will I be in hospital for?

When you come in to have the balloon placed, you’ll likely be in the hospital for around 1  hour from start to finish. Your procedure normally takes around 15 minutes to complete.

Where will my procedure take place?

Because the procedure is so straightforward and requires no anaesthetic, your consultant can perform the procedure in our outpatient department.

Do I need to have the balloon removed?

No, the balloon will deflate and pass naturally after around 16 weeks.

How much weight can I lose?

After approximately 16 weeks of the Allurion Programme, multiple clinical studies have demonstrated that patients lose on average 10–15% of their total body weight. If you still want to lose more weight, a second Balloon can be placed after completing the first programme.

Your consultant will talk to you about your specific goals and situation during your consultation.

When can I go back to work?

We generally advise that you have 1-2 days off work after the procedure.
