What is the Mini Gastric Bypass?

The mini gastric bypass offers similar weight loss to the roux-en-y gastric bypass but is the faster and simpler of the two bariatric procedures. Due to how the mini gastric bypass procedure is performed, the risk of an internal hernia doesn’t apply.

Now firmly established as a treatment offered by the NHS, the mini gastric bypass offers several benefits over the traditional gastric bypass surgery. For example, weight loss outcomes are marginally better, the bowel is not cut through and reattached, there is only one join between stomach and bowel. Less incisions made means less risk and faster recovery overall. This makes the difference between the roux-en-y gastric bypass and mini gastric bypass quite pronounced and worth considering.

How Does the Mini Gastric Bypass Work?

Much like the roux-en-y gastric bypass, the mini gastric bypass procedure works by restricting the intake of food into the stomach. It drastically reduces the size of the available stomach, without removing anything unlike the gastric sleeve. The mini bypass relies on a series of alterations to the stomach that can be better attributed to ‘plumbing.’

As well as restricting the physical size of your stomach the psychological size of your appetite will also be impacted due to the reduction in the hunger hormone (ghrelin) produced as a result of the surgery.

The Mini Gastric Bypass was developed by Dr Robert Rutledge in 1997.

What Can Mini Gastric Bypass Patients Expect?

Pre Op

You’ll be assessed to check that you’re fit for the operation. This may include blood tests, x-rays, and scans, as well as an explanation of the surgery and long-term outlook. You may need to lose weight and reduce the size of your liver. If your liver is smaller, the operation will be easier and safer.

You shouldn’t eat for several hours before your gastric bypass, but you can continue to drink clear liquids until two hours before. Should you need to stop any medication in preparation for your bypass surgery, your doctor will tell you. You’ll also have plenty of time to ask any questions and discuss your concerns before your surgery.

Associated Risks

As with any surgeries, there are risks involved in the gastric bypass procedure. These include excessive bleeding, infection, and blood clots among others. During your initial consultation, the Bariatric Consultant will be able to talk through these risks with you and answer any questions you may have.

In order to have a mini gastric bypass you need a BMI of at least 35. If you have a BMI of 35 you may be eligible, depending on whether you have any co-existing medical conditions or concerns. You can use our Calculator in order to determine your BMI, or use the NHS BMI Calculator.

How is body mass index (BMI) measured? 

An individuals BMI is calculated by using the following formula:

Frequently Asked Questions

What are my weight loss expectations?

Most patients can expect to lose up to 70% of their excess weight in the two years after their surgery.

What is Dumping Syndrome?

Dumping syndrome is a collection of uncomfortable symptoms, such as feeling sick, weak, faint, sweaty and diarrhoea, caused when sugary foods move from your stomach into the small intestine too quickly.
Avoid drinking and eating at the same time to help prevent dumping syndrome.

What can I eat After Gastric Bypass Surgery?

After surgery, you’ll not be able to eat until your X-ray and swallow test. At first, you’ll have to eat a soft diet and your dietitian will give you a diet plan for the weeks after surgery.

Can I Have Excess Skin Removed?

Surgery can be used to remove this excess skin, although under normal circumstances this is considered to be a cosmetic procedure.

What Qualifies Me for Gastric Bypass Surgery?

Must have a body mass index (BMI) of 35.

You must have also tried to lose weight through diet and lifestyle, and be willing to have long-term follow-up appointments and adopt a healthy diet and lifestyle. You’ll also need to be medically fit for surgery and anaesthetic.

How Dangerous is Gastric Bypass Surgery?

Gastric bypass surgery is a common procedure and most people have it without complications, but all surgery carries some risks. Your consultant will discuss potential risks and complications with you before the operation.

Can I Regain Weight?

Yes. The surgery won’t stop you craving or eating unhealthy food. You must be willing to make long-term lifestyle changes in order to avoid putting weight back on.

How Long do I Need off Work?

Depending on how strenuous your work is, you may need to recover for two to four weeks before returning to your job.

Is the Gastric Bypass Permanent?

Gastric bypass surgery is generally non-reversible. There is a risk of you reversing your weight loss if you do not follow the advice provided.

Can I Drink Alcohol?

It’s not recommended that you drink alcohol for the first six months. You will feel the effects of the alcohol faster than before. This is because you will absorb it differently.

Can I Drink Caffeinated Drinks?

It’s okay to drink caffeine after your gastric bypass surgery, but you should avoid drinking too much as it acts as a diuretic and can cause dehydration.

What Medications Should I Avoid?

You should avoid taking a class of medication known as non-steroidal anti-inflammatory drugs (NSAIDs) as these can irritate your stomach and cause stomach ulcers. Common drugs in this category include aspirin, ibuprofen, and naproxen.

How Much Water Can I Drink?

You should try to stay hydrated throughout the day after your gastric bypass surgery. Your dietitian will advise you on what you should be drinking in detail. Please avoid fizzy and sugary drinks.

What Happens if I Don't get Enough Protein?

As you start to lose weight after your bypass surgery, your body will need more protein to maintain your muscle mass and have a healthy metabolism. If you don’t get enough, your body will start to rely on the protein from your muscles. This will cause them to weaken.

Can Gastric Bypass Surgery Cause Low Iron?

Yes. After your surgery, your stomach may start to digest things differently, including the iron in your foods. You may need to take iron supplements during your recovery to prevent any deficiencies, your doctor will advise you.
