Bariatric Surgery - Risks

As with any surgical operations there are associated short and long-term complications such as internal bleeding, anastomosis leakage, blood clot in the legs (deep vein thrombosis; DVT), blood clot in the lung (pulmonary embolism), infection, malabsorption of vitamins and micronutrients (which may lead to anemia, weakness, osteoporosis and neurological problems), internal bowel hernia (less than 1%), ulcer perforation (0.8%), and weight regain.


Within Salford Royal bariatric surgery has been very successful and, over the last five years, we have had very few complications during the operation, and no-one has died within 30 days of the operation (that is how surgeons operations are measured!).

Patients who are morbidly obese have a greatly increased risk of premature death from a number of causes, especially diabetes, high blood pressure, heart and lung disease, as well as cancer. Weight loss surgery has been shown to reduce the risk of death, to improve or reverse the weight-related complications, and to improve quality of life. In the large majority of people, the benefits of surgery far outweigh the risks, but that balance has to be discussed with the surgeon and possibly the anaesthetist.
