Hypothyroidism (Underactive Thyroid) Information
Commonly known as an underactive thyroid, hypothyroidism is a condition that occurs as a result of the thyroid gland decreasing its hormone production. When your thyroid does not make enough thyroid hormones to meet the body's needs, many of the body's functions slow down.
What causes hypothyroidism? Several things can cause this condition, including:
- Radiation treatment.
People with hypothyroidism may experience a wide range of symptoms -- and some people may not have any symptoms at all. Some of the most common symptoms include:
- Weight gain
- Puffy face
- Brittle nails.
Thyroid hormone replacement therapy is often used to treat this condition. This involves medicines such as levothyroxine, Levoxyl®, Synthroid®, Levothroid®, and Unithroid® that work by restoring the levels of TSH and T4 hormones to normal.
