What To Expect After a Gastric Bypass Surgery

This surgery usually involves a 2 to 6 day hospital stay (2 to 3 days for a laparoscopic approach). Most people can return to their normal activities within 3 to 5 weeks.

Gastric bypass surgeries may cause dumping syndrome. This occurs when food moves too quickly through the stomach and intestines. It causes nausea, weakness, sweating, faintness, and possibly diarrhea soon after eating. These symptoms are made worse by eating highly refined, high-calorie foods (like sweets). In some cases you may become so weak that you have to lie down until the symptoms pass.

Gastric Bypass Surgery Qualifications

Although guidelines vary, surgery is generally considered when your (BMI) body mass index is 40 or higher or 35 and you have 2 or more comorbidities (life-threatening or disabling conditions related to your weight).
Your doctor may only consider doing gastric bypass surgery if you have not been able to lose weight with other treatments.
The following conditions may also be required or are at least considered:

  • You have been obese for at least 5 years.
  • You do not have a history of alcohol abuse.
  • You do not have untreated depression or another major psychiatric disorder.
  • You are between 18 and 65 years of age.

All gastric bypass surgeries have risk, and it is important for you and your health care professional to discuss your treatment options to decide what is best for your situation.
