Laparoscopic Gastric Bypass Q & A

What is a Laparoscopic Gastric Bypass?

A laparoscopic gastric bypass is a type of surgical procedure which helps patients to lose weight by changing how the stomach and small intestine accommodate food. The surgery shrinks the stomach which causes the patient to feel full when eating smaller portions of food. The passage of the food is also restricted and it no longer travels to specific parts of the stomach and small intestine. This restriction keeps the body from absorbing all of the calories from the consumed food.

Why are Gastric Bypasses Used?

Weight loss surgery is designed to help those who have not been able to lose weight even though they have taken traditional steps such as exercising and healthy eating. People with a higher body mass index, or BMI, usually around 40 and those who have a threatening or chronic disorder related to their weight, such as type 2 diabetes or high blood pressure, are good candidates for the procedure. Gastric bypass is meant to work in conjunction with healthy dieting and exercise. The patient must learn to control food portions and increase activity levels to truly benefit from the procedure.

What Can I Expect After the Surgery?

Most patients can expect the majority of weight loss to occur in the first 12 months after the surgery and typically recover very well. Weight loss will slow down and then stop over time. Maintaining activity levels and sticking to a healthy diet are crucial to keeping the weight off long after the procedure. Many medical issues can be alleviated by losing weight including:

  • Asthma
  • Gastroesophageal Reflux Disease
  • High Cholesterol and Blood Pressure
  • Obstructive Sleep Apnea
  • Type 2 Diabetes

As the excess weight comes off, patients will find it easier to be more active. Traditionally, after surgery the doctor or a dietitian will create a meal plan or diet to assist you with losing the weight and getting healthy.
