Shown below, are two lists of symptoms. One is a general list of symptoms that may indicate hypothyroidism or an under-functioning thyroid gland. The second list are the general symptoms that may indicate hyperthyroidism or an over-active thyroid gland. Eighty percent of thyroid hormone imbalances that are diagnosed, are in the hypothyroid category. The majority of thyroid hormone disorders are caused by autoimmune disease of the thyroid gland.

What are the main symptoms of "hypothyroidism"?

1. Tiredness, fatigue, lack of energy and stamina
2. Depressed mood, at times alternating with anxiety
3. Dry skin that flakes and dry brittle hair that tends to fall out
4. Constipation from slowed digestion
5. Slowed heart rate, hypotension and at times hypertension
6. Moderate weight gain from slowed metabolism
7. Goiter or nodules of the thyroid

(These symptoms can increase in severity without treatment)

What are the main symptoms of "hyperthyroidism" (generally opposite from
hypothyroidism)?

1. Excessive energy, feeling keyed-up and nervous (resulting in fatigue)
2. Anxious mood, at time alternating with depression
3. Oily skin and hair, excessive sweating
4. Diarrhea
5. Weight loss from increased metabolism
6. Rapid heart rate and hypertension
7. Eyes that bulge or seem exaggeratedly wide-open
8. Goiter or nodules of the thyroid

(These symptoms can also become severe, i.e.; heart and blood pressure)

People who experience a number of these symptoms or even one of them that is concerning, need to see their Doctor for a check up and evaluation. Thyroid hormone imbalances are usually first detected by blood testing and a patient presenting with symptoms of either hypothyroidism or hyperthyroidism, may be referred for a blood draw to test their thyroid function.
