CoolSculpting is absolutely safe for patients with Type 2 Diabetes. Your body processes and reabsorbs the damaged fat cells very slowly over a period of weeks and months. Therefore, the amount of fat being absorbed into the bloodstream at any one time is extremely minimal, and should not affect your health in any way.
You should not have any trouble undergoing treatment so long as your diabetes is managed. It is however something that you should let your provider know about when you go in for a consultation. With regard to the disposal of the fat. The cryolipolysis process leads to apoptosis which means that the fat cells actually break down and self destruct over a two - three month period. As the cells break down they are removed from your body through your lymphatic system in a naturally occurring body process.
