Roux-en-Y Gastric Bypass Surgery
The Roux-en-Y gastric bypass is one of the more invasive weight loss surgeries. The Roux-en-Y gastric bypass has stood the test of time providing reliable, long-term weight loss with little long-term risk of malnutrition or complications.
This Roux-en-Y gastric bypass surgery works in three ways:
• By restricting the capacity of your stomach,
• By reducing your appetite and
• By bypassing part of your digestive system so the fat in foods is not absorbed.
The function of the stomach is to digest food. This digested food passes through the stomach into the small bowel where the majority of nutrients and calories are absorbed. In Roux-en-Y gastric bypass surgery the stomach is made smaller by dividing it into a small upper pouch and a larger remnant pouch. The smaller pouch is then connected directly to the middle portion of the small intestine (jejunum) bypassing the rest of the stomach and the upper part of the small bowel (duodenum).
The stomach is divided into a small upper pouch and a large lower pouch using surgical staplers which provide a seal between the two sections. A piece of the small bowel (jejunum) is then joined to the small stomach pouch bypassing the lower part of the stomach and the upper portion of the small bowel (duodenum).
The upper pouch is small so fills up quickly. The patient feels full and is unable to eat large volumes of food. The digested food then passes directly to the middle part of the small intestine and through the rest of the digestive system. As the digestive system has effectively been made shorter, absorption of nutrients and calories is reduced.
- More rapid initial weight loss compared to restrictive only procedures
- Perceived to offer patients a less restrictive diet
- Carried out using keyhole surgery leaving minimal scarring
- Helps create and maintain a feeling of fullness
- May produce “Dumping syndrome” in patients if they eat too many sweet foods, which may result in nausea, queasiness, vomiting and diarrhoea. (This can be considered a benefit as it forces the patient into healthier food choices or it can be considered a disadvantage of the surgery)
- Makes it easier to adopt changes to your eating habits and lifestyle
There may be other medical reasons why surgery is not right for you. Our team will go through your medical history and the results of any tests you may have prior to agreeing to proceed.
