Case study, Ritchie's story

Ritchie Hooper, showing weight loss after bariatric surgery  
Ritchie Hooper lost nearly 10 stone

Ritchie Hooper from Leybourne in Kent had bariatric surgery.

Ritchie says: "At my heaviest I weighed 25.5 stone and had a 54 inch waist. Sometimes I wonder how I got in that position in the first place.

"In 2009, I was diagnosed with type 2 diabetes and eventually I was put on insulin.

"The criteria for surgery are strict so it's definitely not a temporary fix. You need to be in the right frame of mind before you go ahead with something so invasive.

"I get lots of support from my specialist bariatric dietitian, and I also attend the bariatric surgery support group which meets once a month.

"Since the surgery I've lost 9.5 stone, I'm down to a 36 inch waist and I have come off the insulin.

"Before I would always take the shortest route or get the bus. In the summer there was a rail strike. I decided to walk part of the way to work. I felt great and had the biggest smile on my face when I got there."

Support groups

We run a patient support group once a month. This is for patients who have had or are waiting for weight loss surgery.

The group is run by specialist dietitians and takes place online.

There is a short educational activity or talk. This is followed by a general discussion and questions.

It is a chance to:

  • support each other between appointments
  • share your experience
  • make new friends
