The high ratio of thyroiditis as a main cause of thyrotoxicosis in patients referred to the nuclear medicine department of Babol Shahid Beheshti Hospital

Thyrotoxicosis is a disease that results in excessive thyroid hormone activity in the blood. Common causes include Graves's disease, toxic nodular goiter (single or multiple) and thyroiditis. However, the cause of thyrotoxicosis may be different due to geographical areas, so in this study, the prevalence of thyrotoxicosis in the Babol County was investigated. In this cross-sectional study, 30 thyrotoxic patients who were referred for thyroid scan were evaluated. The thyroid scan was performed with radiopharmaceutical of technetium pertechnetate and based on the results of the scan; the patients were divided into two general groups. The first group increased the absorption of radiopharmaceutical or hyperthyroidism, which included graves and, toxic nodular goitre (single or multiple). The second group reduced the absorption of radiopharmaceutical, which included thyroiditis (subacute and painless). Of the 300 patients with thyrotoxicosis, 209 patients were women (69.7%) and 91 patients were men (30.3%). In thyroid scan, 135 cases of thyroiditis (45%), which 95 cases were women (70.4%) and 40 cases were men (29.6%), 96 patients of Graves (32%), 57 cases were women (4 (59%) and 39 cases were men (40.6%) and 69 cases of adenoma (23%), 57 cases were women (82.6%) and 12 cases were men (17.4%). Thyroiditis in our region may be more frequent than Graves' disease and can be the most common cause of thyrotoxicosis, which can be important in medical decision-making.
