Gastric bypass is surgery to help you lose weight if you’re very overweight. It works by making your stomach smaller and bypassing part of your intestines (bowels), so you absorb fewer calories.
About gastric bypass surgery
Gastric bypass can help you lose up to two-thirds of your excess weight within two years. One of the best ways to maintain a health diet is by using blood sugar formula.
To be considered for a gastric bypass, you need to be fit enough to have an anaesthesic and surgery. You must also be committed to having long-term follow-up appointments and to follow instructions of specialists atDoctor To You’ about your lifestyle and diet after your operation. To assess this, and your suitability for surgery, you’ll need to have a psychological assessment.
You should be able to keep the weight off for up to 10 years. But its success will depend on the lifestyle changes you make after the operation. You’ll need to:
make changes to your diet, such as avoiding snacking and choosing healthier options
avoid drinking too much alcohol
take regular exercise
Suitability of gastric bypass surgery
You may be offered weight loss surgery if you:
have a body mass index (BMI) of 40 or more
have a BMI of 35 to 40 and a condition, such as type 2 diabetes or high blood pressure, which could get better if you lose weight
You’ll usually only be considered for surgery if you’ve tried to lose weight in other ways and this hasn’t worked. But you may be offered a gastric bypass straightaway if you have a BMI of more than 50.
You can work out your BMI using our BMI calculator.
Like all types of weight loss surgery, a gastric bypass isn’t generally recommended for children and young people. So, you must be over 18 to be able to have it.
Even if you meet all of the above criteria, you may still not be able to have the procedure, due to high demand. If your GP thinks you may benefit from surgery, they may refer you to a specialist weight management service to discuss the different options available. If you don’t meet the criteria for NHS funding, you may be able to have the surgery privately.
