Several ways this procedure works
Like many other bariatric surgeries, it creates a stomach pouch that is much smaller and will allow much smaller meals to be eaten, and this means that fewer calories will be taken in. Because the smaller stomach digests less, a part of the small intestine would then absorb nutrients, and calories will no longer have food passing through it, so there may be less nutrient and calorie absorption.
The Roux-en-Y gastric bypass is often referred to as simply gastric bypass, and it is often considered weight-loss surgery’s gold standard.
How Gastric Bypass Works
Restrict your food intake
The most important factor is that the food stream is rerouted, and this creates gut hormone changes that make the patient feel fuller, suppress their hunger, and reverse the way that obesity often leads to type 2 diabetes.
As the term “gastric bypass” indicates, this operation reroutes the food stream past much of the patient’s stomach and the initial portion of the small intestine. It not only forces a smaller food intake, but it also reduces the amount of nutrients that are absorbed.
two main parts to a gastric bypass
First, is that the stomach is made into a small pouch about thumb-sized and will hold about an ounce of volume by dividing the rest of the stomach from its top. The small pouch allows at any one time just a small portion of food to be eaten.
There is also a small bowel division with the help of a surgical stapler about 2 feet in length away from the stomach.
Second, the end of the small intestine is attached to the pouch, called a gastrojejunostomy.
Attached to the stomach’s remnant is the small intestine’s other end, and this is reconnected to the patient’s intestinal tract. This is known as a jejunojejunostomy and allows for digestive enzymes and stomach acids to mix with food.
The internal incisions are generally closed with sutures that absorb back into the body so that there are no stitches that have to be removed. The external incisions are often closed with staples, steri-strips, or sutures, depending on which the surgeon prefers.
Advantages of Roux-n-Y Gastric Bypass
- It produces weight loss that is sustained long term as well as significant and needs only limited dietary compliance to produce an excess weight loss of 60% to 80%.
- It restricts how much food can be taken in.
- It can cause conditions that will increase the expenditure of energy.
- It creates positive changes in the gut hormones that will enhance the feeling of fullness and reduce the appetite.
- It can typically keep the more than 50% excess weight loss maintained.
- It does not need a foreign body to be implanted such as the silastic ring that is required in gastric banding.
- It offers better weight loss than does the adjustable gastric banding.
- The procedure is a combination of methods, offering malabsorptive effects as well as restriction.
Risks of Roux-n-Y Gastric Bypass:
- There is a risk of developing nutrition deficiencies, and this risk is higher than with restrictive surgeries. A gastric bypass has food skip being in the duodenum, where most calcium and iron are absorbed. This may lead to a long-term deficiency in vitamins and minerals like iron, calcium, vitamin B12, and folate.
- Menstruating women may develop anemia because of the B12 and iron malabsorption.
- Decreased calcium absorption can lead to metabolic bone disease and osteoporosis
- Because the stomach is resected and stapled, gastric leaks can occur.
- It can cause patients to have dumping syndrome. This condition results from the contents of the stomach moving through the small intestine too quickly. This can cause diarrhea, sweating, faintness, weakness, and nausea, and it is especially a risk after eating sweet foods.
- Technically, this is an operation that is more complicated than sleeve gastrectomy and gastric banding, and this can potentially mean higher rates of complications.
- It requires that patients adhere to a set of dietary recommendations, taking vitamin and mineral supplements for life, and comply with all follow-ups.
