One of the things that you need to understand about thyroid problems is that most of the symptoms associated with thyroid do not develop immediately and they may take a long time to become apparent. Even when a person starts to show the first signs of a thyroid disease, he or she may brush them off as nothing. Therefore it is always a good idea for a person to be aware of the underlying reasons for such symptoms and consult the doctor to avail the best diagnostic solutions. The doctor is going to first carry out a basic physical examination and ask questions about any health issues or discomfort. Then the doctor is going to recommend tests for evaluating the thyroid hormone levels in the body. This can help to detect if the thyroid gland is overactive or underactive. An FNA or fine needle aspiration can be carried out if the doctor suspects the presence of thyroid cancer. Some of the other diagnostic tests that are associated with thyroid problems include elevated thyroglobulin level, depressed radioactive iodine uptake or RAIU and elevated erythrocyte sedimentation rate. In any case, the doctor may also perform some other evaluations just to clarify and make sure about the specific type of thyroid disease.


One of the most common methods of treating thyroid hormone related diseases is to carry out a hormonal replacement therapy. This particularly works well for hypothyroidism and hyperthyroidism. The doctor may also recommend other modes of treatment depending on the nature of the condition that has affected the patient. The age of the patient is also a determining factor when it comes to the type of treatment chosen and the drugs used. For instance, the medications that would be fine for a teenager may not work in the same way for an adult patient.

It is important to note that the treatment of a thyroid condition may go on for a long time and the patient may recover only gradually. The doctor may also recommend surgery in case of some extreme forms of thyroid problems. If a patient has been suffering from skin conditions, hair fall and depression, he or she may need to see a counselor or a skin specialist. For women who are suffering from thyroid problems, it is advisable to get in touch with a gynecologist. This will help in ensuring a wholesome treatment for the patient.
