This study aimed to indicate the levels of body mass index (BMI), thyroglobulin levels, and interleukin 1 beta among a group of patients women with hyperthyroidism. Samples were collected (60 patients) and 30 healthy women who were considered as a control group in the city of Samarra after confirming that they had hyperthyroidism.
           The results of the study showed a significant decrease in body mass index (BMI) (P ≤ 0.05), as the affected group suffered from a decrease in weight compared to the control group. The results of the (TG) and (IL-1β) tests also showed the presence of a significant increase at a significant level (P≤0.05) in the values of the hyperthyroidism group when compared with the control group.
             It is clear from the results of the study that there is an effect of the disease on the body mass index, and that an increase in the levels of both (TG) and (IL-1β) may indicate an immune influence on the progression of the disease.
