Specialist Weight Loss Surgery Designed Around Your Needs

Every person's reason for considering weight loss surgery is different. For some, it is about improving their health and reducing the impact of obesity-related conditions. For others, it is about regaining confidence, becoming more active or reaching a point where previous attempts at weight loss are no longer delivering lasting results.

Meet Your Harrow Bariatric Surgeon

Weight loss surgery at our Harrow location is led by an experienced bariatric surgeon who believes successful outcomes begin with careful planning, open communication and personalised patient care.

Marco Adamo

Mr Marco Adamo MD is a consultant surgeon and lead surgeon of the Bariatric Unit at the prestigious University College London Hospital. He is specialises in upper gastrointestinal, bariatric and minimally invasive surgery.

Mr Marco Adamo graduated in Italy, where he also completed his training in general surgery. He practiced six years in Yorkshire, where he was appointed consultant in 2006. He was also awarded MD by Leeds University for his research on appetite hormones and bariatric surgery.

Five Years of Dedicated Aftercare

One of the reasons patients choose Tonic is the level of support they receive after surgery. While bariatric surgery is a significant milestone, maintaining successful weight loss depends on continued guidance, encouragement and specialist care throughout the years that follow.

Our structured 5-year aftercare programme has been developed to help patients adapt to lifestyle changes, build healthier habits and maintain successful weight loss. Through ongoing support from our multidisciplinary team, you’ll continue receiving expert advice long after your operation has taken place.

During the first two years, patients receive one-to-one support from:

  • A specialist psychotherapist.
  • A registered dietitian.
  • A bariatric nurse.
  • A dedicated fitness professional.
  • Ongoing follow-up with their surgeon.

This multidisciplinary approach helps patients establish healthier routines, adapt to dietary changes and remain motivated throughout their weight loss journey.

Support then continues for a further three years through dedicated telephone aftercare alongside ongoing surgeon follow-up, ensuring expert advice remains available whenever it is needed.

For many patients, this continued partnership provides reassurance that their journey does not end when they leave hospital. It continues through every stage of achieving and maintaining healthier, long-term outcomes.

I have lost over 10 stone and I feel absolutely incredible. I would never have dreamt to have the life that I currently have now.”

“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.”

“I lost 8.5 stone. I feel like one of the gym girls, I have done a 10k this year and I am signed up to Brighton half marathon next year! I chose Tonic because I saw so many success stories online and because of the aftercare package. You have the dietician, the PT, the psychotherapist and the constant support group from others who have had surgery and the team in the office”
