Can a person suffering from type 2 diabetes undergo Hair Transplant without any fear of complications.

If your diabetes is under control then hair transplant surgery should be no issue. One consequence of having diabetes is poor wound healing.  Fortunately wounds on the scalp with its abundant blood supply heal well (as opposed to wounds on the foot).

Fortunately, the risks of hair transplant are low.  The scalp is very vascular which makes infections rare.  If diabetes is under reasonably good control then I would have no reservations of performing a hair transplantation.  FUE may offer a healing advantage since long linear scars on a diabetic person may be more challenging to heal.

Yes, most individuals with type 2 diabetics can undergo hair transplantation. The vast majority have no problems. I like to order a hemoglobin A1c in my diabetic patients and we sometimes check blood sugars during the procedure. Complications in hair transplantation are rare to begin with. For the 18 million Americans with diabetes, a large proportion would be OK candidate for this type of surgical procedure. However, type type 2 diabetics, mainly "poorly controlled" type 2 diabetics, may have a higher risk of complications.  It would not be correct to assume that complications are impossible for an individual with type 2 diabetes. It is well known that wound healing can be impaired in type 2 diabetes. In fact, wound healing is one of the most important concern in type 2 diabetic individuals. Anyone with type 2 diabetes needs a full evaluation before surgery.
