Gastric Sleeve Surgery
Also known as sleeve gastrectomy, this procedure involves removing 70-80% of the stomach, leaving a tubular pouch. It restricts food intake and impacts gut hormones to reduce hunger.
Advantages
- Controls amount of food held in stomach
- Supports fast weight loss
- Shorter hospital stay than bypass
- Reduces hunger and appetite
!Things to Consider
- Irreversible procedure
- Potential for vitamin deficiency

Gastric Bypass Surgery
The stomach is divided into two parts, creating a smaller pouch. The small intestine is rearranged to connect to both. This limits food intake and calorie absorption.
Advantages
- Long term weight loss
- Controls consumed food amount
- Suppresses hunger via gut hormones
!Things to Consider
- Complex surgery
- Requires longer hospital stay
- Risk of vitamin deficiency

Intragastric Balloon
A non-invasive endoscopic procedure where a saline-filled balloon is placed in the stomach to create a feeling of fullness and reduce food intake.
Advantages
- Non-surgical / Non-invasive
- Very safe procedure
- No permanent changes to anatomy
!Things to Consider
- Temporary solution (6 months)
- Less weight loss than surgery

Adjustable Gastric Band
A band is placed around the upper part of the stomach to create a smaller pouch. The band's tightness can be adjusted by injecting saline.
Advantages
- Lowest level of complexity
- Short hospital stay (<24 hours)
- Reversible and adjustable
- No vitamin problems usually
!Things to Consider
- Slower weight loss
- Foreign body in the body
- Mechanical problems possible

Post-Bariatric Plastic Surgery
After significant weight loss following bariatric surgery, many patients are left with excess, sagging skin. Post-bariatric body contouring surgery removes this excess skin and reshapes the body to help you fully enjoy your transformation.
Our procedures include abdominoplasty (tummy tuck), arm lift, thigh lift, body lift, breast lift, and face/neck lift. These surgeries can dramatically improve body contour and eliminate skin irritation.
