Is gastric surgery a solution to overweight problems?

Nowadays, many people look forward to seeking weight loss treatment as they deal with overweight or obesity which increase the risk of health problems; such as diabetes, high blood pressure, sleep apnea, fatty liver disease, and possibly some types of cancer.

The UK is considered to have one of the highest rates when it comes to overweight problems with 67% of men and 57% women suffering from that problem.

There are many treatments for weight loss and they range from diet, exercise, behavioral modification, pharmacotherapy to surgery. All the options above but the latter, can offer a short-term solution and the loss of weight is basically limited.

Gastric surgery is thought to be one of the best way. Patients interested in this option need to know everything about the gastric bypass requirements.

Gastric surgery

This is a procedure in the field of the bariatric surgery which is designed to reduce the intake of food in people with overweight problems when losing weight by putting on diets and exercising have failed.

It is known as a restrictive procedure since it restricts the food intake, the calories and nutrients the body generally absorbs. This surgery carries a significant risk and side effects, for it requires changes in lifestyle.

Once the surgery takes place, the stomach gets smaller so people will feel full with less amount of food, which will no longer go to some parts of the stomach and small intestine in charge of breaking food.

The Roux-en-Y gastric bypass (RYGB) is one of the most popular surgeries and involves creating a stomach pouch by using staples out of a small portion of the top. Consequently, the bottom part of the stomach is no longer used and it is called the “Blind Stomach.”

What involves a Gastric Surgery

A gastric bypass decreases the stomach capacity as well as allows the passage of food into the jejunum, which is a small bowel joined to the new stomach pouch.

This induces gut hormones changes that lead to the increase of satiety (the feeling or state of being full) so it makes people stop feeling hungry all the time. Because of the changes produced by the surgery, patients have to fulfill all the gastric bypass surgery requirements.

Main steps in the procedure for a Bypass Surgery

There are two important steps that take place in the gastric surgery:

  • Make your stomach smaller: the surgeon will reduce the stomach by using staples. As a result, the food intake will be limited.
  • The bypass: The surgeon will connect the bypass to a section of the small intestine.

The Body Mass Index in the Gastric Bypass Surgery

Measuring overweight in patients is an important matter for Gastric Bypass Surgery. The BMI formula is used to measure the body fat related to other physical metrics and uses the person’s weight in kilograms, divided into the height in meters.

By using the BMI, surgeons can have an accurate determination of the amount of fat in the body. In adults, it is considered overweight when the BMI is over 25.

Based on the information provided by the Centers for Disease Control and Prevention, any person whose BMI is over 30 is considered obese. Individuals over 40 BMI are eligible for a gastric bypass surgery.
