What is a gastric bypass?

A gastric bypass is one of the techniques used in bariatric surgery and is done not only to kick-start  the weight loss process, but also to prevent or treat health problems that are associated with excess weight. Even though obesity has been prevalent for ages, only recently has it been recognised as a disease of multifactorial origin. The first attempts to treat obesity for the sole purpose of weight loss began in 1950s, when jejunoileal bypasses were done to induce a state of malabsorption (a condition when nutrient absorption is impaired). Despite reaching desired weight loss results, the procedure had too many post–operative complications to be deemed successful. The gastric bypass was developed years later, in the 1960s. The surgical technique went through numerous modifications in order to decrease the number of complications and is now one of the most frequently performed bariatric surgeries worldwide.

How does a gastric bypass work?

A gastric bypass consists of two main steps:

  1. Firstly, the top part of the stomach is separated from the rest of the stomach, thus creating a small, 30 mlpouch.
  2. Afterwards, the small intestine is divided and the lower part of it is connected to the new stomach pouch.

In other words, this structure lets food bypass most of the stomach and enter into the middle part of the small intestine. Because of the small size of the stomach pouch, fewer calories are consumed, and the feeling of fullness is reached faster. Additionally, a small degree of malabsorption is caused by the food bypassing most of the stomach and a part of the small intestine. Finally, changing the route of food stream leads to a modified production of specific hormones that suppress hunger and induce the feeling of satiation. A gastric bypass is normally performed  laparoscopically, i.e. via keyhole surgery, when the procedure is performed using a few small incisions rather than a large one. The choice of surgical technique varies with each individual case. The surgery itself takes up to two hours and is done under general anaesthesia.

Who is a suitable candidate for a gastric bypass?

Bariatric surgery is a suitable choice for people, who:

  • have a BMI (Body Mass Index) that is 35 or above with or without conditions associated with obesity;
  • have a BMI of 30 to 35 and one or more comorbidities that are caused by obesity (such as high blood pressure or type two diabetes).

It is important to mention that bariatric surgery is only recommended after the patient has unsuccessfully tried to lose weight via diet and exercise.

Severe obesity is not the only requirement for weight loss surgery: one has to be in sufficient overall health to go through the operation.

Moreover, a patient must be willing to make permanent changes to their lifestyle and take part in long–term follow–ups which involve keeping track of your health, nutrition, behaviour and medical conditions.

In addition, a psychological assessment is necessary for patients considering a gastric bypass. A patient should have realistic expectations as well – even though a gastric bypass causes considerable weight loss, permanent lifestyle changes are a crucial contribution to the results and bariatric surgery should not be seen as a magic pill for weight loss.

It is also worth noting that a gastric bypass might not be the right solution to every patient, as some health conditions might indicate for another weight loss surgery method to be recommended.

How to prepare for gastric bypass surgery? What tests are needed?

What supplements and vitamins will I need to take?

Because of the restricted amount of food and the bypassed intestine, there is a chance of various vitamin and mineral deficiency development. Because of that, you will need to take certain supplements on a daily basis, including:

  • A high – potency multivitamin and mineral supplement that contains a minimum of 25 mg of iron, 400 mcg of folic acid, copper and zinc;
  • Calcium citrate (a dose that usually varies from 1200 to 2000 mg taken in separate stages);
  • 800 to 1000 international vitamin D units;
  • 1 mg of vitamin B12.

Certain adjustments may be made by your surgeon or nutritionist, and later on your GP, and you should make sure to follow the instructions carefully. You should also keep in mind that you will not be able to absorb whole pills as well as you did before, and they might have difficulties passing through your digestive system during the early postoperative period. Therefore, it is recommended to crush the tablets and open the capsules or purchase your medications and supplements in liquid or chewable form for the first month after surgery.

What will my diet look like?

You will have to follow a special diet after the surgery. The consistency of your food will start with liquids and purées before you will be able move on to consuming solid foods. Because of the new structure of your digestive system, you will only be able to eat in small portions. At first, you may feel nauseous or even vomit if you eat a larger portion of food. It is normally recommended not to exceed a 1000 calories per day. Nonetheless, you should make sure to consume foods that are high in protein (you should be getting a minimum of 65 to 75 grams per day). It is also recommended to avoid added sugar and foods and beverages high in sugar (especially carbonated ones). Moreover, alcohol should be avoided altogether at least the first year after surgery. In time, you will be able to add more variety and consistency to the foods in your diet. Be sure to have regular follow–ups with your nutritionist.

What is dumping syndrome?

Dumping syndrome (also known as rapid gastric emptying) is a condition that may develop after gastric bypass surgery and occurs when food moves from your stomach into your small intestine too rapidly. The symptoms are usually present after eating and can be more intense if the meal was high in sugar. You may have dumping syndrome if you experience these symptoms 10 to 30 minutes after eating:

Furthermore, you might experience symptoms of late dumping syndrome. Because of the low blood sugar, you may sweat, feel extremely lightheaded and weak and have a rapid heart rate.

Dumping syndrome can present itself with both early and late symptoms and can develop even after years have passed after bariatric surgery. On average, dumping syndrome can affect at least 3 out of 20 people who have had part of their stomach removed. If your symptoms cannot be controlled by dietary changes, you should contact your doctor.

Can my pouch stretch again?

Your pouch is naturally due to stretch to a certain degree over time. Nonetheless, it is highly unlikely for your pouch to go back to its original size. Even though larger meals should not cause any permanent damage, you should manage your eating habits as mentioned before: avoid overeating, don’t skip meals, be aware of the habit of emotional eating and refrain from carbonated beverages. Maintaining a steady diet will ensure that you are in the best shape possible.

How to ensure my results are successful?

It is also important to take part in the follow–up appointments with your doctor, so your progress can be tracked and any type of complications are noticed as soon as possible. In addition to everything, it is sometimes suggested to join a support group, which helps bariatric surgery patients discuss the issues they face post weight loss surgery.

Will I have loose skin after surgery? How to deal with that?

Due to excessive weight loss, you may be left with loose skin, usually on your abdomen, bottom, breasts, upper arms and thighs. Many people find this uncomfortable both psychologically and physically, as the loose skin can become irritated and painful. If you are bothered by excess skin, it is possible to fix it with cosmetic surgery. You should wait for at least a year or longer after your weight loss surgery to remove loose skin – it is important to reach a stable weight and make sure it does not change dramatically. If you are considering cosmetic surgery for loose skin, you should consult your doctor.

What are the risks?

There are complications associated with any type of surgery, such as the possibility of allergies, blood clot formation (deep vein thrombosis or pulmonary embolism), bleeding or infection. However rare, more specific gastric bypass complications include:

Common myths about gastric bypass
Myth no.1: weight regain
People who have bariatric surgery regain all of the weight. Even though patients do regain a small amount of weight, bariatric surgery has long–term results and high success rates.
Myth no.2: easier weight loss
Bariatric surgery is done because it is an easier version of diet and exercise. In reality, gastric bypass is done for patients who are resistant to conservative methods of weight loss. Weight loss surgery works in a different mechanism than diet and exercise, and it is easier to maintain a stable weight afterwards.
Myth no. 3: impossible pregnancy
Pregnancy is not possible after bariatric surgery. Even though it is recommended to wait at least 18 months after weight loss surgery, the procedure itself does not affect one’s ability to conceive and carry a baby.
Myth no.4: cosmetic purposes
Bariatric surgery is done for cosmetic purposes. Even if losing weight does improve one’s appearance and self-esteem, the main goal of a gastric bypass is prevention or treatment of obesity associated diseases and an increase in a patient’s life span.

How much weight can I expect to lose after gastric bypass?

The degree of your weight loss depends on a variety of factors including how well you keep up with your diet and exercise and your overall commitment to lifestyle changes. On average, patients lose about 70% of their excess weight. However, you should keep in mind that the average weight loss number may not apply to you – there are people who lose more or less weight.
