Preparing for your balloon procedure

Article explaining what bariatric surgery is and highlighting the differences between the procedures

Your pre-operative medical assessment

A very important step you must complete before you can have your gastric balloon procedure is your telephone pre-asessment call. In some cases, due to pre-existing medical conditions,  you may also be asked to visit your hospital to attend for medical assessment. We will let you know if this applies to you.

Telephone Assessment

You will receive a telephone call from one of our Bariatric Nurses to complete a final pre-operative admission assessment. This information is essential to complete your booking and allow hospital admission.

Going to Hospital - what you need to know before and during.

Before your procedure

You will be asked to eat and drink nothing from midnight on the evening before your admission. However, if your procedure is not until the afternoon, you may be allowed a light breakfast in the morning (to be confirmed in your pre-op call). Depending on admission time, the bariatric nurse will advise you accordingly.


You will receive written notification from the hospital or a telephone call from Healthier Weight confirming your admission details. If you have not received this letter within three days of your procedure, call the team on 0121 693 4488

Items to bring with you

You will be asked to take your regular medication on the day of your procedure (with a very small amount of liquid). However, some medication may require specific management and you will be advised about this before admission. In some circumstances (e.g. if you are diabetic) you may be asked to attend hospital in advance of your procedure for tests and to adjust your medication. 

On rare occasions balloon patients may have to spend the night in hospital. This could be due to a reaction to the sedation. Just in case, we advise all patients to please bring with you nightwear, essential toiletries, a dressing gown and slippers.

If you are using a continuous airways pressure (CPAP) machine for sleep apnoea, please ensure you take this to the hospital with you.

What will happen on the day

On the day of admission, you will be taken to the ward where the nursing staff will carry out baseline observations (pulse, temperature and blood pressure etc.) and complete the standard admission forms.

You will be seen by your consultant who will go through the consent form with you. In essence the consent is to confirm your understanding of the procedure, together with the risks and benefits. If you have any concerns or questions, please ensure you raise these with your doctor before signing the consent form.

Do I need someone to take me home?

After sedation we ask you not to drive or operate machinery within 72 hours. If you have driven to the hospital, please ensure there is someone to drive you home. Please be aware that if you choose to drive despite this advice, your car insurance company may not cover accidents that occur during this time.

I have received a bill from the hospital. What do I do?

If you have received a bill from the hospital which you are not expecting, please contact the Healthier Weight Administration Team immediately on 0121 693 4488. In most cases you should not receive a bill for anything that has been included in your procedure package. In very rare occasions this may happen and if so please accept our apologies. Extras such as newspapers, visitors’ meals etc. are not included in the package.

Regular medication

As a general rule, you will be asked to take your regular medication on the day of the procedure (with a very small amount of liquid). However, certain types of medication, for example anticoagulants or drugs for diabetes, may require more specific management and you will be advised about this before your admission. In some circumstances (for example, if you are diabetic) you may be asked to come in to hospital on the evening before the day of the procedure, so that specific tests can be carried out and medication adjusted accordingly.

Note: Please ensure that you take your regular medication with you to the hospital in its original package.
