Understanding Bariatric Surgery: Types, Benefits, and What to Expect

Bariatric surgery refers to surgical procedures that help in weight loss by making alterations to the digestive system. Numerous procedures such as gastric bypass and various other weight loss surgeries are referred to as "bariatric surgery." Bariatric procedures work in several ways, including reducing the amount of food the stomach may hold, lowering the body's ability to absorb nutrients, or doing both simultaneously.

The most common types of bariatric surgeries include adjustable gastric band, gastric bypass, sleeve gastrectomy, and duodenal switch. Gastric bypass surgery helps in losing weight by changing how the small intestine and stomach handle the food people eat. Sleeve gastrectomy involves the removal of about 80 percent of the stomach. In the gastric band, an inflatable band is placed around the top portion of the stomach that creates a smaller pouch above.

Weight-loss surgery, also called bariatric surgery, is an operation which involves making changes to the digestive system and causing weight loss. It is meant for people who are obesity and want to lose weight but haven’t been able to do so via other means.

When & Why a Doctor Performs Bariatric Surgery?

A doctor can recommend bariatric surgery when the patient has a level of obesity, a BMI of more than 40, or a BMI of 35 with conditions like joint pains, diabetes, hypertension, sleep apnea, abnormal cholesterol levels in the blood, and risk of developing heart disease, etc. Bariatric surgery is also considered when exercise and diet don’t work or when you have some serious health problems due to your weight.

What Are the Advantages and Types of Bariatric Surgeries?

1. Gastric Bypass Surgery

Gastric bypass, also known as Roux-en-Y (roo-en-wy) gastric bypass, refers to a type of weight-loss surgery, which involves the creation of a small pouch from the stomach and then connecting the newly created pouch to the small intestine. Following a gastric bypass, food that has been ingested is bypassed by going straight through the small stomach pouch and into the small intestine, avoiding most of the stomach and the first part of the small intestine. One of the bariatric procedures that is most frequently carried out is the gastric bypass. It is used when diet and exercise have failed or when a person's weight is significantly affecting their health. For more than 30 years, the Roux-en-Y (roo-en-wy) gastric bypass has been used, and it also offers a better balance between weight loss and any manageable side effects. The procedure can be carried out robotically or laparoscopically.

Steps Involved in Stomach Bypass Surgery

• The patient is given general anesthesia before the surgery starts.
• Some types of surgeries are performed with traditional large incisions in the abdomen. However, most of these surgeries are performed laparoscopically.
• After making the incisions using the open or laparoscopic technique, your surgeon cuts across the top of the stomach, sealing it from the rest of the stomach.
• Next, the surgeon cuts the small intestine and then sews part of it directly into the pouch. Food now goes into the small pouch of the stomach and directly passes into your small intestine sewn to it.
• Also, food bypasses most of the stomach and the first part of the small intestine, and instead directly enters the middle part of the small intestine.
• Surgery generally takes a few hours. After the surgery, the patient wakes up in a recovery room, and then the medical staff monitors him/her for any complications.

Which type of patients are advised for stomach reduction surgery?

Stomach reduction surgery is advised for a patient who has a body mass index of 40 or higher, or has a BMI from 35 to 40 and shows obesity-related conditions, such as diabetes, high blood pressure, heart disease, or severe sleep apnea.

Gastric Bypass Surgery Cost Range

The cost of bariatric surgery in India ranges from $6000 to $8000.

Success Rate of Gastric Bypass Surgery

The average success rate for gastric bypass surgery is about 96%. In most cases, people who have bariatric surgery lose a considerable amount of weight. About half of all patients will regain a small amount of weight. About 80% of patients consider the surgery a success as they achieve long-term weight loss. The success rate depends on several factors, such as how well you follow your diet plan after the procedure and how much physical activity the patient does. Individual differences may also affect your weight loss because everyone responds differently.

How Soon will I recover after Gastric Bypass Surgery?

Following gastric bypass surgery, recovery usually takes three to six weeks. For optimal weight loss following surgery, the patient needs to develop rigorous eating and activity habits. It is essential that you closely adhere to the surgeon's post-operative instructions to optimize the likelihood of a successful surgical outcome. These instructions will include types and amounts of foods to eat when to follow up, and what activities to restrict.

2. Sleeve Gastrectomy Surgery

With a sleeve gastrectomy, a significant section of the stomach is surgically removed along the larger curvature of the stomach, reducing the stomach to around 15% of its original size. Using a laparoscope, gastric sleeve surgery is a minimally invasive treatment. The surgery involves dividing the stomach into two unequal parts. Nearly 80% of the outer curved part of the stomach is cut away and then removed. The minimally invasive nature of this surgery helps the patient recover faster than a procedure in which the abdomen is opened with a larger incision.

Steps Involved in Gastric Sleeve Surgery

• The patient will have general anesthesia before the surgery. This will cause him/her to sleep through the surgery.
• The surgeon uses laparoscopy and will make several tiny incisions in the upper abdomen.
• The surgeon will now insert a laparoscope and place small surgery tools in these incisions.
• The anesthesiologist will pass a sizing tube via the patient’s mouth down into the stomach.
• Then, the surgeon uses a laparoscopic stapler in order to divide the stomach, making a narrowed vertical sleeve.

When is a Patient Advised for Weight Loss Sleeve Surgery?

Gastric sleeve surgery is advised for individuals who have tried other weight loss techniques without achieving long-term success. Your doctor might advise gastric sleeve surgery if an individual is severely obese with a body mass index over 40. The doctor can also advise if the person has a BMI from 35 to 40 and a health condition like high blood pressure, sleep apnea, heart disease, or type II diabetes.

Sleeve Gastrectomy Surgery Price 

The cost of sleeve gastrectomy surgery varies from person to person depending on numerous factors, such as the age of the patient, the country where treatment is availed, pre-existing conditions, type of surgery, facilities availed, the experience of the surgeon, etc.

The Success Rate of Gastric Sleeve Operation

The gastric sleeve success rate is around 80 to 90%. On average, people see an excess weight loss of around 60-70% within a year of surgery. Most obesity-related health conditions like fatty liver disease, joint pain, high cholesterol, Type 2 diabetes, hypertension, and sleep apnea improve or enter remission. A person is more likely to have successful results from gastric sleeve surgery if they are less than fifty years old, have fewer obesity-related comorbidities, have lower rates of anxiety and hypertension, and have lower rates of earlier abdominal surgeries.

Time is taken to start normal life after stomach sleeve surgery

Patients can return to normal life four to six weeks after the surgery. They should also follow a specific diet. Even after an individual has physically healed from the operation, they need to stick to specific recovery practices. A dietitian or doctor recommends long-term dietary as well as lifestyle changes to have healthy weight loss.

How is Bariatric Surgery carried out and by whom?

Most types of bariatric surgery are done laparoscopically. The laparoscope is inserted via small incisions in the abdomen. The camera attached to the laparoscope helps the surgeon see and operate inside the abdomen without making any large incisions. Laparoscopic surgery can also make the recovery shorter. Surgery generally takes several hours. After the surgery, you wake up in a recovery room, where trained medical staff closely monitor you for any complications. Depending on the procedure, you may be required to stay a few days in the hospital.

What is expected on the day of Bariatric Surgery?

On the day of gastric bypass surgery, the patient will be first taken to a pre-operative room where he/she will wear a hospital gown. A nurse will check the patient’s vital signs and then place a peripheral IV in the arm. This IV is generally used for giving fluids and medications to the patient before and during the surgery. To prevent blood clots, an inflatable compression device will be placed on the legs. The patient may also be given a shot of a blood-thinning agent. Then, an anesthesiologist and the surgical team will briefly discuss the surgery with the patient. The patient may need to sign consent forms. Finally, the patient will be taken into the operating theatre where he/she will be given medication to make them asleep.

Risks Involved in Bariatric Surgery

As with any major procedure, bariatric surgery also poses potential health risks, both in the long term and short term. Risks associated with the surgical procedure include blood clots, excessive bleeding, infection, lung or breathing problems, adverse reactions to anesthesia, leaks in the gastrointestinal system, and adverse reactions to anesthesia. Longer-term risks of weight-loss surgery may vary depending on the type of surgery. Some of these include gallstones, low blood sugar, ulcers, acid reflux, and vomiting.

When & how do I start preparing for my Bariatric Surgery?

To get optimal results from bariatric surgery, you should follow a standard pre-operative program. Months before the surgery, the patient should attend a presurgical lifestyle/education/ program. Then, 2 weeks before the surgery, the patient must follow a liquid-only diet. An individual should start and maintain a workout routine to reach and keep their weight loss goals. Daily calories should be lowered to a range from 1200 to 1500 calories. Caffeinated beverages should be avoided about one month prior to surgery.
