Surgeons performing an operation
Bariatric surgery induces weight loss by altering the digestive system. Preoperatively, patients are screened for their psychological fitness to undergo the procedure. Other pre-op tests for bariatric surgery test liver, heart and lung function.
Echocardiogram
An echocardiogram is often done before bariatric surgery. According to the Merck Manuals Medical Library, this ensures the patient does not suffer from heart failure or pulmonary hypertension, both of which may complicate surgery.
Psychological Screening
A pre-op psychology screening assesses the patient's mental health and helps to evaluate whether bariatric surgery is appropriate, according to the Penn Bariatric Surgery Program at Penn Presbyterian Medical Center.
Sleep Study
A sleep study done as a pre-op test for bariatric surgery determines whether a patient suffers from sleep apnea or other sleep disorders. According to the Penn Bariatric Surgery Program at Penn Presbyterian Medical Center, these conditions do not necessarily rule out bariatric surgery, although depending on their severity treatment may be altered.
Nutrition Screening
Preoperative nutrition screening for bariatric surgery is important to help gain an understanding of the patient's weight loss history and eating habits. The Penn Bariatric Surgery Program at Penn Presbyterian Medical Center states that the pre-op test evaluates eating behavior to help facilitate success following the procedure.
Liver, Kidney and Pulmonary Function
According to the Merck Manuals Medical Library, bariatric surgery patients may be tested for liver, kidney and pulmonary function. These are often recommended depending on a patient's medical history.
