There are several types of thyroid diseases that result from either an overproduction or underproduction of thyroid hormones. Hyperthyroidism is caused by Graves' disease, toxic adenomas, subacute thyroiditis, or rare pituitary or thyroid gland issues and results in excessive thyroid hormone production. Hypothyroidism stems from an underproduction of thyroid hormones and can be caused by Hashimoto's thyroiditis, removal of the thyroid gland, excessive iodine exposure, lithium use, or rare thyroid cancer. Thyroid problems cause low energy levels due to improper hormone regulation in the body.

2. Types of Hyperthyroidism Types of Hyperthyroidism
Hyperthyroidism is the overproduction of
thyroid hormones

3. Graves' diseaseGraves' disease
The production of too much thyroid
hormone.

4. Toxic adenomasToxic adenomas
Nodules develop in the thyroid gland
and begin to secrete thyroid hormones,
upsetting the body's chemical balance;
some goiters may contain several of
these nodules.

5. Subacute thyroiditisSubacute thyroiditis
Inflammation of the thyroid causes the
gland to "leak" excess hormones,
resulting in temporary hyperthyroidism
that generally lasts a few weeks but
may persist for months.

6. Pituitary gland malfunctions or cancerous Pituitary gland malfunctions or cancerous
growths in the thyroid glandgrowths in the thyroid gland
Although rare, hyperthyroidism can
also develop from these causes.

7. Types of Types of HypothyroidismHypothyroidism
Stems from an underproduction of
thyroid hormones. Since your body's
energy production requires certain
amounts of thyroid hormones, a drop in
hormone production leads to lower
energy levels.

8. Hashimoto's thyroiditisHashimoto's thyroiditis
In this autoimmune disorder, the body
attacks thyroid tissue. The tissue
eventually dies and stops producing
hormones.

9. Removal of the thyroid gland:Removal of the thyroid gland:
The thyroid may be surgically removed
or chemically destroyed as treatment
for hyperthyroidism.

10. Exposure to excessive amounts of iodideExposure to excessive amounts of iodide
Cold and sinus medicines, the heart medicine
amiodarone, or certain contrast dyes given
before some X­rays may expose you to too
much iodine.
You may be at greater risk for
developing hypothyroidism, especially
if you have had thyroid problems in the
past.

11. LithiumLithium
This drug has also been linked as a
cause of hypothyroidism.

12. Cancer of the thyroid glandCancer of the thyroid gland
is quite rare and occurs in less than 10% of
thyroid nodules. You might have one or
more thyroid nodules for several years before
they are determined to be cancerous. People
who have received radiation treatment to the
head and neck earlier in life, possibly as a
remedy for acne, tend to have a higher­than­
normal propensity for thyroid cancer.
