What is hypothyroidism?
You have hypothyroidism when the thyroid gland does not make enough thyroid hormone. (The thyroid gland is in the front of your neck.) Having too little thyroid hormone causes many symptoms. If you have any of these symptoms, tell your healthcare provider.
- Feel tired all the time.
- Have weak muscles.
- Be constipated.
- Gain weight.
- Have heavy or long menstrual periods.
You may have other problems:
- You feel cold a lot of the time.
- Your hair may be coarse or dry, or it may turn gray at a young age.
- Your skin may get thick and dry
- Your tongue may get thick.
- Your eyelids may be swollen.
- Your voice may deepen or grow hoarse.
Still other problems include:
- Slowed heart rate.
- Loss of interest in sex.
- Loss of hearing.
- Numb and tingling hands.
When this disease is not treated, these problems can happen:
- Swelling of the thyroid gland (which is called a goiter).
- Loss of consciousness or even a coma.
- Heart failure.
How does it happen?
Hypothyroidism most often happens to women over age 40, but it can happen to anyone at any time. For example, it may happen if:
- You have a disease, often a virus, that causes your thyroid gland to swell.
- Your brain isn't signaling your thyroid to make enough hormone.
- Your thyroid gland has been exposed to radiation during cancer treatment.
Often it is not known why the thyroid gland is not producing enough thyroid hormone.
How do I know if I have hypothyroidism?
Your healthcare provider will ask about your symptoms and examine you. You will have blood tests to measure the thyroid hormones your body makes.
How is it treated?
Your healthcare provider will prescribe thyroid hormone medicine. This will take the place of what your body would normally make.
- After you take the hormone pills for about a week, you will feel better.
- You will have another blood test to make sure you are taking enough hormone.
- After a few weeks, you should have no signs of the disease.
- Most likely, you will need to take your pills every day for the rest of your life.
- You will need to have a blood test to check your thyroid hormone level every few months for the rest of your life to make sure you are getting the right amount of thyroid hormone. As your body changes with time, the amount of medicine you need can change, too.
Taking your hormone pills is a safe, simple, and inexpensive way to keep healthy. It's important to:
- Take your pills every day, exactly as prescribed by your healthcare provider.
- Follow your provider's instructions for getting your thyroid hormone level checked regularly.
- Keep your follow-up appointments.
- See your healthcare provider if any of your symptoms are not getting better or they come back.
- You have new symptoms.
