How do bariatric weight-loss surgeries treat obesity?

Reyap Hospital

Severe obesity is a critical medical condition capable of affecting the patient's day-to-day lifestyle. Different aspects, such as physical, social, and emotional aspects, change drastically, which leads to more complications. Aside from that, a lot of chronic diseases are also linked to obesity. In fact, according to WHO, obesity has reached epidemic proportions globally. Due to this, governments, international partners, civil society, non-governmental organizations, and the private sector are now alarmed as the number of people who are obese is increasing. Thus, finding out solutions to address this health issue is essential.

Solution for Obesity

Fortunately, bariatric surgeries have demonstrated to be safe and effective treatment options. This is not only for their weight-loss capacities but also for their improvement in metabolic and hormonal affections. Also, it plays a major role in hunger and satiety and other conditions that appear as a result of obesity.

It is indicated for those patients with a BMI >40 or a BMI of 35-40 with associated comorbid conditions, such as type 2 diabetes, high blood pressure, etc., in whom conservative weight-loss measures have failed. Other criteria exist, which have to be discussed beforehand with the health professional.

Bariatric Weight-Loss Surgeries

Choosing the appropriate type of bariatric surgery depends mostly on the goals of each patient and the expert opinion of the surgeon. Every decision must be based on the chances of maximizing the outcome of the surgery. With this in mind, available bariatric weight-loss surgeries include:

  • Adjustable gastric banding. Also known as LAP-BAND®, it consists of the placement of a non-permanent silicone band or “belt” around the upper part of the stomach, separating it into a tiny upper portion and a larger lower one.
  • Gastric bypass surgery. It consists of surgically reducing the stomach to a small portion; this way, the amount of food the patient is able to eat is reduced drastically.
  • Gastric sleeve. Also known as sleeve gastrectomy, it involves the removal of a sleeve-like portion of the stomach, reducing it to a definitive small portion.
  • Gastric balloon. It involves the minimally invasive placement of a deflated balloon inside the stomach, for then inflating it, reducing the available gastric space.
  • Stomach stapling. Also known as vertical banded gastroplasty, it is a procedure similar to sleeve gastrectomy. It is a process that involves the reduction of the stomach through permanent stapling.
  • Biliopancreatic diversion with duodenal switch. It consists of removing the outer margin of the stomach, rearranging the intestines in such a way that the mixing area between food and digestive juices is shortened.

The listed items above are just some of the surgeries that you can choose from. But, as mentioned, it varies per condition. Wanting to be skinny or less fat is not a bad thing. However, considering factors is vital to avoid any possible complications that may be met in the future.  Take note that there are some risks that you may experience after or while in the procedure. Due to this, talking to an expert should be done first.

The Most Common Surgeries

Among the mentioned bariatric weight-loss surgeries, Gastric Bypass and Gastric Sleeve are the most common. Both are effective, however, there’s a considerable difference between them. To explain why, here are their advantages and disadvantages:

Gastric Bypass

To start, below are advantages and disadvantages of getting Gastric Bypass:


  1. This procedure limits the amount of food that can be consumed.
  2. Another advantage of Gastric Bypass is it gives significant long-term weight loss.
  3. It also leads to conditions that increase energy expenditure.
  4. >50% excess weight loss is the typical maintenance of this surgery.
  5. Gastric Bypass also gives favorable changes in gut hormones that reduce the appetite and enhance the satiety of the patient.


  1. Usually, people who have undergone this surgery stay longer at the hospital.
  2. It is also essential to remember that this procedure requires devotion to the recommendations on a diet, taking life-long vitamin or mineral supplementation, and compliance to follow ups.
  3. People who have undergone this can experience long-term vitamin/mineral deficiencies, particularly deficits in vitamin B12, iron, calcium, and folate.
  4. Also, this is technically a more complex operation, which could potentially result in higher complication rates.

Gastric Sleeve

Now, let’s move on the advantages and disadvantages of Gastric Sleeve:


  1. In this procedure, the smaller stomach still functions and usually works. So, the patient is still able to tolerate most foods, but in small portions.
  2. Also, the patient will be less likely to have ulcer due to less acid secretion.
  3. The intestines remain intact even after the operation, so there is a lesser chance of intestinal obstruction, anemia, osteoporosis, and protein and vitamin deficiency.
  4. Gastric Sleeve eliminates the upper portion of the stomach. It is a part where hormones are produced and stimulate hunger. Which means the appetite often lessens.
  5. There will be no adjustments or foreign bodies that will cause obstruction, slippage, or erosion.


  1. Unfortunately, this surgery is non-reversible since a part of the stomach will be removed.
  2. The body of the patient can still tolerate arb-rich and high-fat foods. This means it can slow weight loss.
  3. Without the intestinal bypass, weight loss can be more difficult or can be lessened.
  4. Also, insurance companies may not cover this operation since it is considered an investigational procedure.
  5. In this operation, stomach stapling is involved. Thus, there will be potential for leaks and other complications.

Given the facts above, you should be able to know which between the two is best for you. At the end of the day, the decision is still yours to make. But, before you decide, you should consider various factors to avoid risk and waste of money anymore. Perhaps the major thing to consider is looking for the best hospital to get the surgery done. You have to ensure that the place is reliable and provides high-quality services like Reyap Hospital.
