Weight loss surgery is a serious step. Patients with psychiatric conditions such as depression, bipolar disease, and/or schizophrenia should be under the care of a psychiatrist before they consider surgery. These conditions can become exaggerated by the body changes that are associated with weight loss. There are some medical conditions that make the surgery too risky to perform. These rarely occur but must be taken into account. If patients meet the eligibility guidelines that are outlined above, they will be candidates for the surgery.
