My thyroid was removed, can I have Liposcution again?

I do not know of any reasons why having your thyroid removed would prevent you from being able to undergo liposuction surgery. You need to consult with a board certified plastic surgeon and determine if there are any other reasons why you would not be a good candidate. Hypothyroid conditions are very common and I have never seen a patient have a complication with liposuction as a result of their thyroid hormone levels. 

 Generally speaking, the ideal patient for liposuction surgery is one who has achieved a long-term stable weight, is medically (psychologically and psychosocially) stable and presents with diet and exercise resistant adipose tissue of  specific areas, with good quality overlying skin elasticity. When the time is right, seek consultation with well experienced board-certified plastic surgeons who can provide you with good, specific, and ethical advice. Best wishes. 

If your metabolic situation is stabilized after thyroidectomy there is no contraindication to liposuction.
