Patient Coordinator

Raj Jain

Raj formed Allure Weightloss after previously working for the manufacturer’s of the Elipse Balloon (Allurion Technologies). He grew the UK Elipse market substantially and was involved with many of the clinics and doctors that provide the Elipse in the UK. For 12 years prior to working with Allurion, Raj worked with other global medical device companies in the bariatrics and aesthetics fields. His experience often is found valuable for patients as he shares a full 360 overview on the various options and technologies available for weight loss patients.

Raj believes the Elipse Programme is a ‘game changer’ with it’s success record and proven safety profile, and this convinced him to form Allure Weightloss – to offer patients the best in class Elipse Programme in the UK in order to help patients achieve their weight loss ambitions.

His belief in the programme together with his own “tried everything” weight loss struggles led Raj to participate in the programme himself and have the balloon. Raj is likely to be your first point of contact with Allure Weightloss and will no doubt share his own personal journey with the Elipse.
