People who are considering surgery to help them lose weight may be overwhelmed by the many weight loss surgery procedures available today. Thus, it is important for them to know the pros and cons of each method to help them make an informed decision. Below is a discussion of the main surgical methods that help in weight loss.
Gastric bypass surgery
This is probably one of the most common weight loss surgery options. It involves the surgeon dividing the stomach into two equal parts, ensuring that the upper section of the stomach is sealed off from the lower part. What follows is a direct connection of the upper stomach to the small intestine’s lower part. Bypassing some components of the digestive system ensures that smaller amounts of calories are absorbed into the human body.
Pros: This surgery option is beneficial because it results in dramatic weight loss, which occurs within the initial six months after the surgery. A person may continue to lose weight close to two years later. As a result of the surgery, lifestyle diseases such as obesity and diabetes tend to improve significantly, leading to an overall improvement in one’s quality of life.
Cons: A major disadvantage of this method is that it impairs the ability of the human body to absorb food effectively. This means that the important nutrients needed by the body may fail to be absorbed into the bloodstream. This has an effect of making a person vulnerable to nutritional deficiencies. Therefore, taking supplements is important for the remaining part of one’s life after undergoing gastric bypass.
In addition, a significant number of people who undergo the surgery experience dumping syndrome, which results from food being deposited rapidly into the intestines without proper digestion. As a result, they may suffer from bloating, nausea, diarrhea and even stomach pains.
Adjustable gastric banding
Adjustable gastric banding is one of the least invasive weight loss surgery options. It entails separating the stomach into two parts by squeezing it with an inflatable band. This reduces the channel connecting the two sections and thus slows the speed at which food empties from the upper to the lower part of the stomach. As a result, it helps to limit the amount of food a person consumes at one sitting.
Pros: The procedure can be reversed through surgery by removing the inflatable band. In addition, the invasion during surgery is minimal, and one recovers quickly after the procedure.
Cons: Unlike gastric bypass, adjustable gastric banding does not result in quick weight loss. In fact, there is a high likelihood of people who have undergone this procedure regaining some of their lost weight after a couple of years.
Sleeve gastrectomy is another weight loss surgery option one may want to consider for weight loss purposes. It involves removal of nearly 75% of the stomach, leaving a narrow tube that leads to the intestines. In serious cases where one is obese and needs to lose a lot of weight, this procedure usually precedes gastric bypass.
Pros: This method is considered safer and simpler for obese and sick people, as there are lower risks involved in it.
Cons: Its major drawback is that it is completely irreversible; it cannot be undone, meaning that one has to live with the surgery’s consequences for the rest of his life. It is therefore very important that one is completely sure of their decision before undergoing this type of surgery.
