Medical concerns

You'll have a medical exam to diagnose any unknown obesity-related conditions. Your doctor also will test for problems that could make surgery more complicated. You may undergo tests for:

• Sleep apnea
• Cardiovascular disease
• Kidney disease
• Liver disease

You'll likely not be able to have surgery if you have these conditions:

• Blood-clotting disorders
• Severe heart disease that prohibits the safe use of anesthesia
• Other conditions that increase the risk of using anesthesia
