What are common complications with a gastric sleeve or a lap band?

Eating problems: With an experienced surgeon, complications from both procedures should be very low, probably less than 2%. Most problems I see arise from patients eating incorrectly. Eating to large of a bite, too fast or not chewing well can lead to nausea,vomiting,reflux & discomfort. This can also happen if a patient's band is filled too tight. Make sure you follow your surgeon's recommended eating guidelines
