Endocrine SurgeryThyroid Disease
Written By Rosette Sclavos

Thyroid hormone levels are usually well-regulated. However, certain conditions can cause too much hormone production, resulting in hyperthyroidism (overactive thyroid).

Conversely, some conditions can lead to too little hormone production and hypothyroidism.

A blood test will assess these hormone levels when a thyroid issue is suspected.

Before any surgery, it is vital to address any significant abnormalities.
