What Is Gastric Bypass Weight Loss Surgery?

Gastric bypass surgery is a minimally invasive surgery for weight loss. During gastric bypass surgery, your surgeon makes changes to your stomach and small intestine to change the way they absorb and digest food. The intervention involves creating a small sac from the stomach and connecting it directly to the small intestine, speeding up the patient's metabolism promoting weight loss.

Gastric bypass

  • Restricting the amount of food that your stomach holds
  • Limiting the amount of calories and fat your body absorbs
  • Changing your gut hormones, which help you feel fuller longer, contribute to appetite suppression and the reversal of obesity-caused metabolic syndrome

Procedure and recovery time

The gastric bypass procedure lasts 45 minutes and requires two nights of hospitalization. It is performed laparoscopically (2 incisions of 0.5 cm and the camera 1 cm). Recovery is virtually immediate; in approximately 3 days after discharge from the hospital the patient can return progressively to all activities.

Gastric bypass is done to help you lose excess weight and reduce the risk of weight-related health problems that can be life-threatening, such as the following:

  • Gastroesophageal reflux disease (GERD or Acid Reflux)
  • Heart disease
  • High blood pressure
  • High cholesterol levels
  • Sleep Apnea
  • Type 2 diabetes
  • Stroke
  • Sterility

Over time, people who are obese or overweight have used alternatives such as exercise, diet, and medications to try to control their overweight. However, most people end up suffering from complications such as high blood pressure, heart attacks, hormonal alterations, erectile dysfunction, diabetes, cerebrovascular events and joint damage and repercussions, among others.

Today, BARIATRIC SURGERY is the best choice for sustainable weight loss that lets patients achieve a healthy weight.
