Brief Answer: Thyroid Detailed Answer: You will likely benefit form treating this condition. Before you consider treatment options it will be necessary to diagnose the cause. This entails a thyroid related blood test and a special type of test called 'Radio Active Iodine 123 isotope Uptake and Scan'. However, it may not be feasible if you are nursing your infant, but still check with your local Endocrinologist and Nuclear Medicine physician as to what their advice is on this matter. If the scan is not an option, a test called TSI (Thyroid Stimulating Immunoglobulins) will be of assistance, although the Scan is more definitive in terms of distinguishing between the major types of hyperthyroidism. Essentially the idea is to understand if you have Graves disease or Thyroiditis. The latter often resolves spontaneously within several weeks and only needs symptomatic treatment such as beta blocker medications. The former is a more chronic form, for which you will need to consider the 3 options available for treatment ie medication (PTU not preferred now except in first trimester of pregnancy), Radiation and Surgery. Thyroid conditions can be complex to deal with and it is best you see an Endocrinologist to obtain a correct diagnosis followed by appropriate treatment options.
