Obesity Surgery

Obesity Surgery

Obesity is among the common diseases of people, regardless of young or old. Obesity, which brings with it excessive fat in the body and therefore weight problems, is a disease that should be treated in a timely manner.

Different treatment methods have been developed by experts to treat this disease. Among these methods is gastric bypass surgery. This method has become popular in recent years and is applied in many health institutions. Here are the things to know about this method applied for people to get rid of obesity;

What is Gastric Bypass?

Gastric bypass is an application that reduces the size of the stomach and reduces the absorption of nutrients by bypassing the small intestine. This application is also known as gastric bypass and gastric bypass.

In the gastric bypass procedure, the remaining part of the stomach, except for 10% of the stomach, is deactivated and a small stomach is formed. Then the small intestine, which is responsible for the absorption of nutrients, is bypassed. By performing these two separate procedures, it is aimed to reduce the amount of food reaching the stomach and intestine.

What Does Gastric Bypass Do?

Gastric bypass, a surgical operation, reduces the amount of food the stomach can hold. Since the stomach size is decreased, individuals feel full more quickly, which helps prevent weight gain due to excessive food intake.
The gastric bypass treatment method is not only used for obesity. It is also applied to patients with high blood pressure, sleep apnea, and diabetes. Particularly when surgical intervention is necessary for treating diabetes, gastric bypass becomes an appropriate treatment option.
The decision for patients to undergo gastric bypass surgery is made after a series of tests and evaluations. After determining the surgery date based on the obesity and metabolic surgery program, the surgeon performs the procedure using a laparoscopic method.
Gastric bypass, also known as stomach reduction, is a surgical procedure performed in an operating room.
Obesity surgeons employ three different techniques for gastric bypass operations. The techniques preferred by surgeons for helping individuals overcome obesity include:

  • Proximal technique
  • Mini gastric bypass technique
  • Distal technique
For individuals recommended for gastric bypass surgery to resolve health issues, appropriate tests and evaluations must be conducted. This ensures that there are no contraindications for the surgery. If negative findings occur during these examinations, the surgery is canceled.
The recovery period after gastric bypass surgery is crucial. There are several considerations patients must pay attention to for a successful recovery:
  • Patients should stay in the hospital for an average of 4 days.
  • They must obtain approval from their doctor before leaving the hospital.
  • Patients should avoid lifting heavy objects for 1.5 months.
  • They must adhere to the nutrition program prepared by their doctor.
  • Gastric bypass may cause difficulties with driving, so patients should be cautious for about 2 weeks.
  • The return-to-work period is typically 3-4 weeks, but it may extend to 2 months or more depending on the nature of their job.

With gastric bypass, the small intestine is also shortened, resulting in a decrease in the amount of nutrients absorbed. Because the small intestine is connected to the newly formed stomach, less food is absorbed. Nutrients that are not absorbed go directly into the digestive system and are excreted, preventing weight gain. This also helps prevent future obesity-related problems.

Gastric bypass not only facilitates weight loss but also eliminates diseases such as high cholesterol and diabetes that arise from obesity. This allows people to live healthier lives.

For What Diseases Is Gastric Bypass Used?

In cases of diabetes, sleep apnea, and hypertension, individuals' body mass indexes must fall within the suitable range for the procedure to be considered. This is essential for deciding on surgery.

How Is Gastric Bypass Performed?

To conduct the surgery, a 1 cm incision is made in the patient's body using laparoscopic devices. Through this incision, access is gained to the stomach. The stomach is then divided into two parts, referred to as the large and small stomach. The entry to the stomach is closed during this process. After dividing the stomach, a bypass procedure is performed for the small intestine.

The bypass performed in the small intestine is also known as "bridge" bypassing. This procedure allows the shortening of the small intestine and connects it to the newly created small stomach, resulting in less nutrient absorption.

This process prevents food from reaching approximately 90% of the stomach and the remaining part of the small intestine. Instead, food is digested and excreted without passing through these sections.

Where Is Gastric Bypass Done?

To ensure the surgery proceeds smoothly, the obesity surgeon and their team work meticulously in the operating room. They also utilize sterilized surgical materials to complete the procedure.

What Are the Techniques for Gastric Bypass?

These techniques are determined based on the patient’s health condition, body mass index, and the surgeon’s discretion. Once the technique is chosen, the procedure is carried out in a sterile environment.

Pre-Operative Considerations for Gastric Bypass

If no adverse conditions are found, the surgery is approved. If a surgery date is scheduled, the patient is required to fast for at least 10 hours prior to the operation. Additionally, they should not consume any liquids.

Post-Operative Considerations for Gastric Bypass

Aside from these, if medication is prescribed by the doctor post-surgery, patients should use these medications as directed to prevent pain, infection, and other side effects.
