Hypothyroidism means your body does not make enough thyroid hormone to keep normal levels of the hormone in your blood. Hypothyroidism is more common as people age. It affects women more often than men. Be sure to talk with your health care team to learn more about the causes.
Your Thyroid Gland
The thyroid gland is a butterfly shaped gland in the front of your neck. The cells in a normal healthy thyroid gland send out hormones, tri-iodothyronine (T3) and thyroxin (T4). When your thyroid gland gets a message from the brain that your body needs these two hormones, the thyroid gland sends them into the bloodstream. The blood then carries these hormones to the rest your body. These hormones are needed to control your body’s metabolism, growth, and activity of your nervous system.
When your body does not make enough thyroid hormone, you may have one or more of these symptoms.
Recent weight change
Decreased energy level
Intolerance to cold
Dry skin and hair
Coarse or thinning hair
Neck pain or swelling
Hoarseness of voice
Changes in menstrual cycle
Change in sleep habits
Joint or muscle pain
When your thyroid gland is not making enough thyroid hormone, your health care provider may give you a thyroid hormone. The pill often given is Synthroid®, or levothyroxine sodium. You will need to take your medicine each day at about the same time. The medicine needs to be taken on an empty stomach. Take at least 30-60 minutes before breakfast and other medicines each day. This medicine needs to be taken 4 hours apart from multivitamins, iron supplements, antacids, soy and calcium supplements. These supplements block the thyroid medicine from being absorbed.
Once you start taking a thyroid pill, you will need to have follow-up blood tests. These tests are needed to make sure you are taking the right dose. Your doctor will tell you when to return for blood tests. Once you have the right dose, your signs and symptoms should improve. This will likely
happen within a few weeks and resolve in 3-6 months or longer. Be sure that you keep taking your medicine even when you are feeling better.
Hypothyroidism is a lifelong condition. It must be treated with medicine. Do not stop taking this medicine unless told to do so by your doctor.
Your doctor may need to change the amount of medicine you are taking. Once you have started your medicine, you will need to watch for changes in how you feel.
Signs of too much thyroid hormone (hyperthyroidism):
Feeling warm when nobody else does
Unable to sit still
Hair may become fine and silky
Contact your health care team if you are having symptoms of too much or too little thyroid hormone, or if you have any questions.
