Bariatric surgery

The Bariatric surgery section of The Body Optimist brings together information and first-hand stories about weight-loss surgery: gastric sleeve, gastric bypass, gastric band, preparation, follow-up care and body contouring. It's for people who are considering surgery or have already had it, with no promises about results and no judgment about their choice.

What the Bariatric surgery section covers

• The procedures: how sleeve gastrectomy, gastric bypass and the adjustable gastric band work.
• Preparing for surgery: medical and nutritional evaluations, and getting ready psychologically before the operation.
• Life after surgery: eating, digestive side effects such as dumping syndrome, getting back to exercise and long-term follow-up.
• Body contouring: plastic surgery on the skin after major weight loss, such as a body lift.
• Personal stories: experiences that differ widely from one person to the next, including weight regain.

How is the decision to have bariatric surgery made?

Bariatric surgery is a major treatment, and the decision is made with a specialized multidisciplinary team: a surgeon, a physician specializing in nutrition or endocrinology, a dietitian, and a psychologist or psychiatrist. Medical guidelines set eligibility criteria and recommend a thorough evaluation and preparation beforehand, followed by lifelong medical and nutritional follow-up. The surgery has lasting effects on digestion: vitamin and mineral supplements are often needed, complications can occur and results vary from person to person. Take the time to ask all your questions, and consider getting a second opinion.

Frequently asked questions

What are the main types of bariatric surgery?

The best known are sleeve gastrectomy, which removes a large part of the stomach; gastric bypass, which makes the stomach smaller and reroutes part of the small intestine; and the adjustable gastric band, which is used less and less. Each procedure has its own constraints and risks, to discuss with your surgical team.

Why is follow-up care after surgery so important?

Because the surgery has lasting effects on how you eat and absorb nutrients. Lifelong follow-up, as recommended by medical guidelines, helps monitor for deficiencies, adjust supplements, support you through psychological changes and catch any complications early.

What is dumping syndrome?

Dumping syndrome happens when food, especially sugary food, moves too quickly from the stomach into the small intestine. It can cause nausea, cramps, sweating, a racing heart or dizziness, from a few minutes to a few hours after eating, and is more common after gastric bypass. Your care team can help you adjust what and how you eat.
