Mini Gastric Bypass Surgery

People who choose Mini Gastric Bypass Surgery can enjoy sustainable and long-term weight loss. Reducing the size of the stomach pouch results in you feeling full more quickly and reduces the intake and absorption of calories.

Although each individual is different, on average someone who has Mini Gastric Bypass surgery can lose up to 35% of excess body weight in the first year after surgery. 

The positive health outcomes from Mini Gastric Bypass surgery include weight loss and the reduction of conditions related to increased weight. This includes but not limited to:

• Type 2 Diabetes
• High Cholesterol
• High Blood Pressure 
• Heart Disease 
• Stroke
• Mobility issue
• Joint pains
• Cancer
• Sleep Apnoea
• Infertility

Weight loss and better health can also improve the quality of your life and mental health, boosting self confidence and opening up new doors for how you want to live your life

Professor Puraksyastha will walk you through the preparation steps in the weeks leading up to your Mini Gastric Bypass surgery. The support you are given is tailored to you, following full metabolic, dietetic and psychological assessments. This is to ensure the best preparation and outcomes possible.

Our specialist dietitian will help you to prepare for your Mini Gastric Bypass surgery by undergoing a pre-operative liver-reduction diet lasting two weeks. The diet is low in fat and moderate in protein and low in calories, providing approximately 800-1000 kcal per day. The aim of the pre-operative diet is to shrink your liver meaning it can be moved more easily, making the operation safer. In the 24 hours before your surgery, you will be required to restrict your food and drink intake. 

Our specialist psychotherapists will also help you to be best prepared for your surgery, ensuring you have the psychological support to ensure best outcomes.

Dietary changes

There are three stages of texture modification diet following surgery, starting with a liquid diet and gradually building this back up to a long term, solid textured food.

Your specialist dietitian will help explain and guide your through the post-operative diet which follows the below stages:

• liquid diet (10 days)
• puree diet (3-4 weeks)
• soft diet (for around 6 weeks)

This is followed by a lifelong healthy, high protein diet of a normal solid texture from 12 weeks onwards.

Fluid intake remains important and you should aim to drink 1.5 litres a day.  Avoid high calorie fluids including hot drinks made with sugar and fizzy drinks as these can cause bloating and discomfort.

Alcohol should not be taken for three months after surgery and after this time in moderation after food.  

Lifestyle changes

Exercise –  After surgery we advise you to move around as much as possible and ensure that you don’t get dehydrated.  Exercise should be gentle for the two months –  i.e. swimming, walking, cycling. No heavy lifting or weight training for at least eight weeks

In the long-term increased activity levels are needed alongside a reduced dietary intake for optimal and sustained weight loss after bariatric surgery.

Driving – You should not drive for the first two weeks following surgery and contact your insurance to find out what their guidelines are.  

We suggest that when you are ready to drive that you ask a family member or a friend to drive you to a quiet street where you can attempt an emergency stop. If it feels comfortable then it is fine for you to drive.

Travel – We advise that you do not take a long haul flights for 8 weeks following your surgery

You can take flights of no more than 2 hours duration from two weeks after your surgery

Pregnancy – We advise you to avoid pregnancy for 2 years after surgery. Oral contraception can be restarted 1 month after surgery

Smoking – It is strongly advised to quit smoking in the long-term as this can undo the positive health outcomes from surgery, and increases risk of ulceration in the gastric pouch, chest infections, cancers and heart disease.

After your recovery period has ended, you can start to enjoy the lifestyle changes that come about from better health and increased mobility associated with Mini Gastric Bypass surgery.
