It is important to differentiate between the deficiency type and excess type of the disease. The case at the onset is often of the excess type mostly due to qi stagnation, liver fire, stagnant phlegm and blood stasis. The prolonged case belongs to the deficiency type, often characterized by yin deficiency or deficiency of both qi and yin. Clinically, the disease is categorized into the following syndromes: qi and phlegm stagnation, liver fire attacking the stomach, deficiency of both qi and yin, deficiency of heart yin and liver yin, and thyroid crisis.

The treatment is based on the principles of regulating qi to resolve phlegm, clearing away heat and purging fire, and softening hardness and dissipating mass. For the prolonged case with blood stasis, the principle of promoting blood circulation to remove blood stasis should be added. While for hyperactive liver fire affecting yin, tonifying yin should be taken as the main principle. In case of deficiency of spleen qi and stomach qi, tonifying qi and invigorating the spleen should be adopted.

Hyperthyroidism is when your thyroid gland, located at the front of your neck, produces too much thyroid hormone, causing your metabolism to speed up. This may seem like a good thing, but when your body works too hard it can take a big toll on your heart, bones, and mood. Hyperthyroidism has three forms that share several symptoms. The most common form is Graves disease. Hyperthyroidism may be caused by taking too much thyroid hormone when you are being treated for hypothyroidism. Hyperthyroidism is more common in women than men and usually occurs after age 60.

Hyperthyroidism is a set of disorders that involve excess synthesis and secretion of thyroid hormones by the thyroid gland, which leads to the hypermetabolic condition of thyrotoxicosis. The most common forms of hyperthyroidism include diffuse toxic goiter (Graves disease), toxic multinodular goiter (Plummer disease), and toxic adenoma.
