What Is Hypothyroidism?

Hypothyroidism is a medical condition in which a person’s thyroid gland does not produce enough of certain, important hormones. The thyroid is a small gland located at the front of your neck, which is responsible for providing energy to organs within your body. It is involved in important functions such as your heartbeat and your digestive system.

When there is a lack of thyroid hormones in the body, a person’s natural function begins to slow down. It is a fairly common condition that primarily affects people over the age of 60. It is more common in women than in men.

Signs and symptoms of hypothyroidism include:

  • Weight gain
  • Fatigue
  • Slowed heart rate
  • Decreased sweating
  • Depression
  • Sensitive face
  • Elevated blood cholesterol
  • Dry skin
  • Impaired memory
  • Menstrual changes
  • Stiffness in joints
  • Muscle weakness

Symptoms typically progress over the years. Book an appointment with our team of Specialists to learn more about hypothyroidism today.

What Is Synthroid?

Synthroid is a brand name for levothyroxine, a medicine used to treat hypothyroidism. It is typically taken as a tablet, though it is also available as an oral capsule or injectable solution.

Synthroid works by providing the thyroid hormone that your thyroid gland produces when it is functioning normally. Generally, Synthroid is taken for life in order to maintain the proper functioning of your body and its organs.
