What Is Weight Loss Surgery And How Does It Work?

Weight loss (bariatric) surgery is a surgical procedure performed on the digestive system by highly skilled medical professionals to help extremely obese patients lose weight. Unlike liposuction, where a chunk of fat tissue is removed from the body, weight loss surgery focuses on limiting the amount of food you consume and absorb.

This is done in two ways. First, by restricting the stomach area so that it cannot hold too much food, thereby preventing overeating or making you feel full sooner. And second, by shortening your small intestine, where the nutrients get absorbed, thereby preventing absorption of broken down food molecules that get converted into fat when not used as an energy source.

Bariatric surgery is minimally invasive and is done using a laparoscope. It is the most preferred method as it causes less pain and speeds up the healing process (2). However, a few open bariatric surgeries are also done depending on the condition of the patient and after taking their consent. But does this work? Find out in the next section.

Does Weight Loss Surgery Work?

Yes, weight loss surgery or bariatric surgery works for morbidly obese patients. Since it prevents you from overeating and reduces the absorption of nutrients, you will lose weight gradually. It will seem like you are losing weight naturally.

But you also have to be careful after you have undergone weight loss surgery. Proper diet and lifestyle should be followed to prevent regaining the weight. Moreover, patients suffering from depression or binge eating disorders need to be careful as they are prone to gaining the weight back (3).

So, yes, bariatric surgery helps you lose weight, but it also comes down to how determined you are to change your lifestyle, adhere to a new and better routine, and avoid gaining the weight back. But instead of predicting the future now, let’s focus on the present – do you really need a bariatric surgery? Find out next.

Weight loss surgery is not for everyone. Sometimes, you might feel you are overweight, whereas, in reality, you are not. Or you need to lose a little weight, which can be accomplished by choosing a better lifestyle. So, how do you know if weight loss surgery is the only option left for you? Well, experts have designed a checklist to screen patients suitable for bariatric surgery. Here are the criteria to qualify for weight loss surgery:

Apart from these, the questionnaire provided by the hospital will also determine whether you are the correct candidate for bariatric surgery or not. The doctors take the decision based on a number of factors so that the surgery is successful and helps you in the long run.

Now, let’s take a look at the types of weight loss surgery.

Types Of Weight Loss Surgery

Bariatric surgery is of four types. Your doctor will determine which type of surgery will be best for you, and each has its own pros and cons. Take a look.

1. Roux-en-Y Gastric Bypass

Also known as Gastric bypass, it is the “gold standard” of bariatric surgery.

Procedure

First, the surgeon staples the upper part of the stomach and creates a small pouch. Next, he/she cuts the small intestine and attaches the lower part of the small intestine to the newly created small stomach pouch. Now, the upper part of the small intestine is then attached to the lower part. The stomach becomes smaller, and hence, you cannot eat a lot and will feel full soon.

Attaching the lower part of the small intestine to the small pouch limits the absorption of calories. And attaching the upper part of the small intestine to the lower part aids proper digestion by supplying the digestive juices produced by the glands in the stomach lining.

Pros
Cons

2. Gastric Sleeve Surgery

Also known as sleeve gastrectomy or laparoscopic sleeve gastrectomy. Here’s how it is done.

Procedure

The surgeon removes 80% of the stomach. The remaining stomach, which now looks like a banana, is too small to hold too much food. Therefore, you eat less and lose weight.

Pros
Cons

3. Adjustable Gastric Band Surgery

Also known as laparoscopic adjustable gastric band surgery. Here’s how it is done.

Procedure

The surgeon places a ring with an inner inflatable band at the top part of your stomach, thereby creating a small pouch. It is similar to tying a knot with a band. The remaining part of the stomach remains below the band. Now, the inflatable band is filled with salt water by the surgeon to adjust the opening of the stomach pouch. So, when the stomach is small, you will eat less and prevent weight gain.

Pros
Cons

4. Duodenal Switch Surgery

Also known as biliopancreatic diversion with duodenal switch (BPD/DS), it is the most complex weight loss surgery. Here’s how it is done.

Procedure

First, a gastric sleeve surgery is carried out. Next, the duodenum and the last portion of the small intestine are divided, and both of these are joined together. About three-fourth of the small intestine is bypassed. The upper part of the small intestine that carries pancreatic enzymes and bile (important for digestion and absorption of fats and protein) is reconnected to the last portion. The small stomach pouch cannot hold too much food, so you will eat less. And since the pancreatic enzymes and bile get mixed at the end of the small intestine, fewer calories get absorbed.

Pros
Cons

These were the four weight loss surgery procedures that can help you lose the fat and lead a disease-free life. But the main question is, how much weight will you lose? Here’s what we found.
