I would suggest finding a good diet and exercise program for life that you can do to manage your weight issues. Liposuction will remove a collection of fat, but is not a weight loss procedure and will not control future weight gain. I am not certain of your terminal illness question. You may also want to be checked for food allergies. eating wrong foods, food you are allergic to, can make weight loss very difficult.
Although, laser liposuction is a good treatment to aid in the removal of areas of excess fat, no liposuction is a substitute for a good diet and exercise program. I would suggest you get back on a reasonable diet and exercise program you can stay on, indefinitely. Then, if you have problem areas of fat you may consider options such as laser liposuction. best wishes Dr Lepore.
