Weight Regain after Gastric Bypass (Roux-en-Y)

The Gastric Bypass (Roux-en-Y) is an effective proven treatment for Obesity management.

Gastric Bypass ( Roux-en-Y) Surgery creates a small stomach pouch which is connected to a loop of the small bowel (the duodenum is bypassed.)

The bypassed remaining stomach and the small bowel are reconnected downstream which enables the digestive juices from the stomach, liver and pancreas to mix with the food and allow some of it to be absorbed.

The Gastric Bypass is a restrictive and malabsorptive weight loss surgery, meaning it both restricts the amount of food consumed and restricts the absorption of calories. Usually the Gastric Bypass produces superior weight loss results.

Long term Weight Regain after Gastric Bypass is possible, usually if poor habits occur… snacking between meals, poor dietary choices and lack of exercise, the same habits that originally created the obesity.

During the first year after surgery it is vital to adopt new dietary habits, exercise patterns, lifestyle habits and to change your mindset otherwise you are likely to return to the weight you were before surgery.

Bariatric surgery requires commitment and compliance from the patient, the surgery alone will not prevent weight gain for the rest of your life. A healthy balanced diet and exercise will help to maintain weight loss long term. Emotional difficulties can often lead to reverting to old bad habits, the habits that led to the obesity in the first place. It is therefore essential that emotional needs are addressed. You can overcome these difficulties with understanding and professional guidance.

If you are experiencing difficulties please do not be disheartened or embarrassed, the sooner you seek dietary and psychological help, the more likely you are able to get back on track and prevent a large increase in weight.

Re-Surgery Options:

Resize the gastric pouch

The aim of this surgery is to return the stretched gastric pouch to its original size. The smaller the pouch, the less food you will need to feel full.

Lengthen the bypassed limb (the Roux Limb)

This procedure converts the Proximal (conventional) Bypass (Roux-en-Y) to a Distal (lengthened) Roux-en-Y Bypass. This procedure will increase the malabsorptive element of the Gastric Bypass.

Addition of a Gastric band over the stomach pouch

This procedure attempts to reduce portion sizes and slows down gastric emptying.

Conversion to Duodenal Switch

This procedure is not normally performed in the UK due to high risk of nutritional deficiencies.

However it must be noted that the above are of little use long term unless diet, exercise, lifestyle and mindset are changed.

Hockey Stick Syndrome Surgery (Candy Cane Syndrome)

It is possible that the no longer-functioning portion of the small intestine near to the new join of the bypassed stomach and small intestine is causing abdominal pain, nausea and vomiting. This is called Hockey Stick Syndrome (or Candy Cane Syndrome).

Once the non-functioning portion of the intestine is identified (called the hockey stick or candy cane) it can be laparoscopically (keyhole surgery) removed. The vast majority of patients experience complete resolution of their symptoms post surgery.
