2. Introduction
• As a board-certified otolaryngologist, Dr. Frank Brettschneider treats a
variety of disorders of the ear, nose, throat, head, and neck. Dr. Frank
Brettscheider draws on an in-depth knowledge of both hypothyroidism
and hyperthyroidism.
The thyroid gland, located at the front of the neck, functions as a source of
hormones that maintain balance in metabolic function. Therefore, when
the thyroid malfunctions and secretes either too much or too little of the
required hormones, the patient experiences either a substantial increase
or a substantial decrease in metabolism.
An under-functioning thyroid, known as hypothyroidism, slows the body's
metabolism. A common congenital condition, it may also occur as a result
of damage to the thyroid, inhibited hormone production, or acquired
disease of the hypothalamus or pituitary gland. Signs vary based on the
patient's individual condition but can include fatigue, oversensitivity to
cold, muscle discomfort, and weight gain.

3. Hyperthyroidism vs. Hypothyroidism
• Patients may also present with a variety of ancillary
symptoms, such as dry skin and memory difficulties.
Hyperthyroidism, by contrast, results from an excess of
thyroid hormone in the body. Often a result of
hormone overproduction, prompted by disease or an
excess of iodide in the body, it may also develop from a
specific form of thyroiditis or other cause of
uncontrolled hormone release. Symptoms stem from
an overstimulated metabolism and may range from
heart palpitations and anxiety to insomnia and
difficulty concentrating. Other signs include weight loss
and menstrual irregularity.
