I am a 42 year old African American female with a colostomy resulting from rectal cancer diagnosed in 2002, removed with surgery in 2003. I have a history of asthma, joint pain, back pain, and high blood pressure. I do not have sleep apnea, however I do sleep with my mouth open. I have a BMI of +50, and I weigh 392lbs at 5'9" tall. I would like to know if I could be a candidate for any form of gastric bypass surgery? I am on steroids for my asthma, which make losing weight very difficult.
