You do stand a chance at having the lap band weight loss surgery. For starters your bmi is probably over 40 and with your health problems that will help you get approved. I had alot of health problems along with being overweight,I wasn't 100lbs overweight but i had enough health problems to get approved. I am 5'2 also and i weighed 216 at the most when i started on my journey to having the surgery. Most insurances require a six month study with your Dr and a weight loss program before they will approve the surgery. I wish you the best of luck on your journey.
