If you rely on replacement thyroid hormones, here's why it's important to take your prescribed dosage:

If left untreated, hyperthyroidism may lead to serious heart problems and be life-threatening. If your body is always running on overtime, you may have abnormal heart beat, sudden cardiac arrest, or hypertension (high blood pressure). A thyroid storm is when your heart rate, blood pressure, and body temperature go to dangerous levels due to un- or under-treated hyperthyroidism.

If left untreated, hypothyroidism may lead to serious problems and could be fatal. Slow heart rate means your blood isn't moving to vital parts of your body fast enough. Decreased body flow to organs like the kidneys can lead to failure. Hypothyroidism can affect  fertility and menstruation in women, and testosterone levels and sperm shape in men. Myxedema coma is when you are severely hypothyroid with decreased mental status, hypothermia, and other symptoms from slowed function all over your body.
