Can I get a liposuction while being diagnosed with secondary hypothyroidism and Hashimoto thyroiditis?

Sorry to hear about your recent diagnosis.  Fortunately this is an extremely common - and easily managed disorder.  With daily medication and periodic monitoring of blood levels, your thyroid function can be essentially restored to normal.  I suggest waiting until your levels have been appropriately controlled with your medicated as instructed by your primary care physician.  At that point, you would absolutely be a candidate for surgery!  Obviously it is important to discuss this with your surgeon as well as primary care physician. 

Thank you for the question. As long as your thyroid disease is being managed appropriately, keeping your thyroid hormone levels within normal range, you will remain a good surgical candidate. I would also ask for a surgical clearance from your endocrinologist.
