Hyperthyroidism, a condition where the thyroid gland is overactive, can arise from several causes.
Common Causes of Hyperthyroidism
The primary causes, as outlined in the provided reference, include:
- Graves' disease: This autoimmune disorder is the most frequent cause of hyperthyroidism.
- Toxic nodular goiter: This involves one or more nodules on the thyroid that become overactive.
- Thyroiditis: Inflammation of the thyroid gland can temporarily lead to hyperthyroidism.
- Excessive thyroid medicine: Taking too much thyroid hormone medication can also trigger this condition.
Symptoms of Hyperthyroidism
As the reference also points out, common symptoms associated with hyperthyroidism include:
- Nervousness and irritability.
- Excessive sweating (perspiration).
- Fine and brittle hair.
Treatment Options
Treatment approaches, as noted, can include a combination of:
- Medications to reduce thyroid hormone levels.
- Radioactive iodine therapy.
- Surgery to remove part or all of the thyroid gland.
- Beta-blocking medications to manage heart-related symptoms.
| Cause | Description |
|---|---|
| Graves' Disease | Autoimmune disorder causing thyroid overactivity. |
| Toxic Nodular Goiter | Overactive nodules on the thyroid gland. |
| Thyroiditis | Inflammation of the thyroid gland. |
| Excessive Thyroid Medicine | Taking too much thyroid hormone medication. |
In summary, hyperthyroidism stems from various underlying issues that overstimulate the thyroid gland. Understanding these specific causes allows for targeted diagnosis and treatment.
