Hyperthyroidism is the result of excess thyroid hormone production,
causing an overactive metabolism and increased speed of all the body's
The thyroid gland
regulates the body temperature by secreting two hormones that control
how quickly the body burns calories and energy. If the thyroid produces
too much hormone, the condition is called hyperthyroidism, but if too
little is produced the result is hypothyroidism.
Although the exact
cause is not known, hyperthyroidism possesses the symtoms of: irritability,
nervousness, a perpetual feeling of being hot, less frequent and/or
decreased menstrual flow, hand tremors, intolerance of heat, rapid
heartbeat, insomnia and fatigue, weakness, hair and weight loss, and
sometimes protruding eyeballs.
According to Traditional
Chinese Medicine, hyperthyroidism is the result of kidney yin deficiency,
which is characterized by two groups of symptoms.
The first is the
result of a deficiency in energy related to kidney function, such as
dizziness, fatigue, forgetfulness, lower back pain, tinnitus, and general
weakness. The reproductive system may also be affected in this group.
The symptoms in
the second group are caused by "empty heat" represented by
dry skin, frequent thirst, hot flashes, insomnia and night sweats.
