1 · A pouch about the size of an egg
Your surgeon makes a small pouch at the top of your stomach. It fills with a small meal, so you're satisfied with much less.

Patient Care Award 2025
In our patients' own words
“Meeting Dr Loy to discuss the best surgery for me, I felt it was the first time in my life I was genuinely being listened to and not just blamed or judged for being overweight.”
“I was extremely anxious on the day of my surgery, but their calm, reassuring presence eased my nerves immediately.”
“The nurses and doctors provided me with top care and made me feel human, not just like another patient through the swinging door.”
What could change for you
You've tried diets, apps, slimming clubs, maybe weight loss medication. If the weight keeps coming back, it isn't because you didn't try hard enough.
“The weight always comes back.”
Most people lose about 70 to 80% of their extra weight. If you're 5 stone over, that's about 3½ to 4 stone.
“My knees and back ache.”
With less weight to carry, back and joint pain often ease, so stairs and walks get easier.
“I have type 2 diabetes or high blood pressure.”
Both often ease as the weight comes off.
“I hide at the back of photos.”
Imagine stepping into the family photo instead of taking it.
How a gastric bypass helps
2 · Food takes a shorter route
The pouch is joined further down your gut, so food takes a shorter route and a small meal is enough.
3 · Usually home the next day
It's keyhole surgery through small cuts, 1 to 2 hours under general anaesthetic. You usually spend one night in hospital and recover in about two weeks.
Nervous about an operation? That's normal.
- “What if I feel sick after eating?”
Sugary food can make you feel faint or sick soon after eating. It's called dumping syndrome. Your dietitian shows you which foods to avoid.
- “Will I need vitamins for life?”
Yes. You take vitamins and minerals every day and have regular blood tests. We guide you on both.
- “I'm scared of the operation itself.”
Dr John Loy, who leads our bariatric unit, has done almost 3,000 weight loss operations. He answers every question before you decide anything.
- “I'm worried I'll be judged.”
Not here. You'll be listened to, not lectured.
- “Am I even suitable?”
That's what your free assessment is for.
Support that stays with you
The operation takes a day. Your support carries on long after it.
A dietitian programme, so you know what to eat at every stage.

“The team hand hold you throughout, follow up calls, check ins, and as Dr Loy said on the day of leaving after the Op, our care continues for months following the Op, which was comforting when you are at home afterwards.”

Not sure a bypass is the right one?
You don't have to decide alone. At your free assessment, Dr Loy recommends the operation that suits your health. If you've read about the mini bypass, he performs it when he judges it fits; most people are recommended another option.
