Prior to your Bariatric Surgery you will need to have a medical assessment to ensure your safety for surgery. This will either be by your local General Practitioner (GP) who will need to perform a basic physical examination covering your Pule rate, Blood Pressure, Heart and Respiratory examinations and an ECG. The alternative for people with more significant health issues will be a referral to a Physician for formal assessment.
The decision which way to go is made at your consultation.
