Bariatric surgery is a procedure performed on obese individuals in order to help them achieve rapid weight loss. The risks associated with bariatric surgery fall into two main categories: those related to restricted food intake and rapid bariatric surgery weight loss and those associated with the surgical procedure itself.
Accordingly, bariatric surgery side effects can be categorized as:
- Immediate post-operative complications
- Infection of the wound and of the operative site (affects around 1 in 20 patients)
- Internal bleeding (occurs in around 1 in 100 patients)
- Development of blood clots (occurs in around 1 in 100 patients). Clots may develop in leg veins (deep vein thrombosis) or travel up to the lungs causing a pulmonary embolism, which can be life threatening.
