Bariatric Surgery and Schizophrenia Diagnosis

Hi,

I have a brother who is extremely overweight and also has been diagnosed with schizophrenia.  He has had schizophrenia for the last 20 years and is under a doctor's and takes the necessary medicine for it.  Does anyone know of a doctor or hospital in the Maryland area that would consider him for bariatric surgery given his mental condition?  I've consulted with the bariatric surgery center at one hospital in Maryland and they will not perform surgery on him due to this condition.

Thanks very much...Joe
