Obesity is a medical condition that has become a global public health issue. Due to the worldwide obesity epidemic, bariatric surgery has become the optimal treatment option for people who want to achieve sustained weight loss.

What Is Bariatric Revision Surgery?

The term bariatric surgery refers to changes made to the digestive system to help you lose weight by holding less food in the stomach. Many patients have long-term benefits with this procedure and do not require revision surgery, but some may develop issues.

Bariatric surgery no doubt feels appealing, but sometimes it does not work. Can we get bariatric surgery twice? — Many people wonder. So yes, it is the solution! If you previously had surgery, that wasn’t successful for you, and you put the weight back on afterward. You are qualified to have bariatric revision surgery. It would be beneficial to remove the complications from the prior surgery that prevented weight loss.

There may be gradual weight gain after a few years of surgery. It could be due to many reasons depending upon the type of surgery. Here, revision surgery can help you to achieve your weight loss goals. Here is a quick review of revision surgeries.

Gastric Sleeve Revision Surgery

If you already underwent this procedure and revisions are required— it is done using the endoscopic sleeve gastroplasty ESG method. With endoscopy, the stomach is operated through the throat. Without making any incisions, the stomach size is reduced by sutures. On the surgeon’s recommendation— a patient can return home within a few hours.

Gastric Bypass Revision Surgery

It is known as a transoral gastric outlet reduction. If you previously had gastric bypass surgery and need to undergo it again. During the procedure, the stomach’s connection to the small bowel is reconfigured.

Sometimes surgeon inserts sutures to the stomach via endoscope without any incisions made.  After doing this, the patient quickly feels full and stops overeating, this causes weight reduction. The patient can go home the same day.

Signs of a Failed Bariatric Surgery

Every patient’s body is different and can have these or related symptoms. It is normal to regain weight after initial success of the procedure.

Gaining Weight Following Bariatric Surgery

Bariatric surgery patients notice heavy weight loss in the first few months after the procedure. It is because the patient’s stomach size is reduced during the surgery, and the body heals post surgery. During this time, patient is on a strict diet advised by the doctor.

The human body works on the adaption policy according to the circumstances. If a patient does not follow a proper diet and starts consuming large portions, it may stretch the stomach to its regular size. If they continue to do so, the surgery goes ineffective.

Why Is My Weight Loss So Slow After Gastric Bypass?
