Hypothyroidism is a condition where the patient has a deficiency in hormones produced by his thyroid gland. There are various thyroid conditions, both with excessive and insufficient function (as well as other types) -- and this category covers the latter of those two groups. Before you read further, please keep in mind that what is presented on this page is not intended to be taken as a replacement for medical advice from a professional. If you need advice, diagnosis, treatment, etc., please contact someone who might be able to assist you.
Triiodothyronine (T3) and thyroxine (T4) are thyroid hormones. When they are not present in sufficient amounts then there is said to be a deficiency -- hypothyroidism. Not only can a problem with the thyroid gland itself cause this, but in some circumstances it can be brought on by issues with the hypothalamus or pituitary gland.
Hypothyroidism can lead to a wide range of symptoms. A few of the possibilities for ones that may occur early in such a condition include: goiter (a form of swelling in the gland), brittleness and thinness of the fingernails, and a heart rate below sixty beats per minute (known as bradycardia). A couple possible symptoms in later stages of such a disease include the following: skin (particularly on the face) that is dry and has a puffy appearance, and speech that is slow with a voice that displays hoarseness. There are also potential symptoms which are more rare, such as: loss of hair, difficulty in swallowing, and high cholesterol levels.
