Thyroid disease in women tests. The thyroid is a small gland in the front of the neck. The thyroid makes hormones called T3 and T4 that regulate how the body uses energy. Thyroid hormone levels are controlled by the pituitary gland, which is a pea-sized gland in the brain. It makes thyroid stimulating hormone (TSH), which triggers the thyroid to make thyroid hormone. In thyroid disease the immune system makes antibodies that damage thyroid cells and interfere with their ability to make thyroid hormone. Over time, thyroid damage can cause thyroid hormone levels to be too low. This is called an underactive thyroid or
Thyroid storm In cases, where critical illness is accompanied by thyrotoxicosis, this comorbidity prevents the down-regulation of thyroid function. Therefore, the consumption of energy, oxygen and glutathione remains high, which leads to further increased mortality. These new theories imply that thyroid storm results from an interaction of thyrotoxicosis with the specific response of the organism to an oversupply of thyroid hormones. The diagnosis of thyroid storm is based on the presence of symptoms consistent with severe hyperthyroidism, as outlined in the Signs and symptoms section above. Multiple approaches have been proposed to calculate the probability of thyroid storm based on clinical criteria,
