I am 68 years old, 5'2" tall, and weigh 320 pounds! My family doctor suggested bariatric surgery 20 years age. I went through all the pre op "stuff" and got my surgery date. I was afraid and cancelled! So, Im finally ready and my lung doctor said Im at high risk! I have severe sleep apnea, asthma, and use oxygen . I am sad! Do I chance a stroke or blood clot? My heart doctor said I was ok,
