Why choose Nuffield Health Leicester Hospital for your gastric bypass surgery?

Our recently refurbished Leicester hospital provides the perfect setting to begin your life changing weight loss surgery journey. Our highly experienced bariatric consultants will be with you every step of the way, from your first consultation right through to your thorough aftercare.

Before, during and after your gastric bypass operation you will be well supported by our dedicated matron-led nursing team. If you have tried conventional weight loss methods in the past without success and think you are a candidate for bariatric surgery, arrange a consultation with one of our experts today.

What happens during a gastric bypass?

  • A gastric bypass is performed under general anaesthetic and usually takes between two and four hours
  • Your surgeon will usually use laparoscopic (keyhole) surgery
  • They will make several small cuts on your abdomen
  • Your surgeon will place surgical instruments along with a telescope inside your abdomen to perform the operation
  • Your surgeon will create a tunnel behind your stomach
  • They will pass a stapling device through the tunnel and then staple your stomach to create a smaller stomach pouch
  • They will divide your small bowel below your stomach and bring up the lower end and attach it to your new stomach pouch
  • The contents of your new stomach pouch will now bypass the rest of your stomach and the first part of your small bowel.

Going home after gastric bypass surgery

  • You should be able to go home the day after your procedure
  • Your stomach may be sore and you may experience nausea or vomiting
  • These symptoms should ease quickly
  • You will start with a liquid-only diet, progressing to soft food and then to solid food
  • Due to nutritional deficiencies created by gastric bypass you may need dietary supplements for the rest of your life
  • Some patients experience “dumping syndrome” if they eat the wrong foods; resulting in nausea, vomiting and diarrhoea
  • You should be able to return to work after two to four weeks depending on the extent of surgery and your type of work
  • Many patients experience rapid weight loss in the first 6-9 months following gastric bypass
  • It is important that you maintain any diet or exercise programme prescribed in order to continue this progress.

What complications can occur with gastric bypass surgery?

General complications of any surgical procedure may include:

  • Pain
  • Bleeding
  • Infection of the surgical site (wound)
  • Unsightly scarring
  • Developing a hernia in the scar
  • Blood clots (deep vein thrombosis).

Although rare, specific complications of a gastric bypass may include:

  • Damage to internal organs
  • Surgical emphysema
  • Developing a hernia near one of the cuts
  • Pouch stenosis
  • Staple-line bleeding
  • Anastomotic leak
  • Developing a hernia inside the abdomen
  • Change in bowel habit or diarrhoea
  • Nutritional deficiencies
  • Anastomotic ulcer
  • Developing gallstones

The decision to have gastric bypass surgery must be considered very carefully. Our experienced consultants and bariatrics nurses can give you all the information you need.

What other weight loss treatments are available at Nuffield Health Leicester Hospital?
