“Life before surgery was fake, I had a happy face but was not really happy. I wouldn’t go on lads holidays with my friends or take my kids swimming. 

I have lost over 10 stone and it’s been life changing. I have got my life back. I can now take my kids swimming, go on holiday, do those things that I should have done 10,15,20 years ago.”

“Before I had surgery, I’d always yo-yoed with my weight. I was ashamed because of the size I’d gotten to. I was unable to buy the clothes I wanted to wear. I didn’t feel like the person that I wanted to be nor did my reflection match the person I felt inside. 

The surgery with Tonic has absolutely changed my life. I’ve lost 5 and a half stone, and I am more confident and outgoing.

“Before weight loss surgery, I couldn’t cope with doing anything strenuous and I couldn’t spend time with my children in the way I wanted to. My eating was out of control, and I had been yo-yoing. 

A year out from surgery, I’m a completely different person. Last year, my body fat percentage was in the morbidly obese category. Now, I’m in the healthy weight category.”
